He didn’t come from a wealthy family. He’s not a Hollywood superstar, nor does he have some amazing tal ents, like script-writing, politics or athleticism. However, what he has is something that is available to us all, and that is a determination to succeed.At the age of 25, Cardone took the first job that he could find. That job was as a car salesman. It was a title and a position that Grant was not very fond of. However, the economy was slow, which meant he didn’t have many options, so he made it work.Cardone was committed to becoming the best salesperson he could be. So, he invested (投资) heavily in his own self-improvement by reading books and studying his craft and his industry. After committing himself to becoming his very best, his income quickly doubled. And soon thereafter, he became one of the best car salesmen in the country. He eventually moved on to running his own business, and was extremely smart and disciplined (自律的) with his money. Cardone only spent money on what was absolutely necessary for food and housing. He would place anything left over into an investment fund just for the property market.Cardone’s focus on learning more so that he could earn more, along with having the discipline to invest his extra money, instead of wasting it on useless things, helped him become a self-made millionaire just five years later by the age of 30.Cardone has since gone on to become a well-known international businessman, speaker and the owner of Cardone Capital, a $ 1.5 billion investment firm. He’s authored the New York Times bestselling books If You’re Not First, You’re Last, and other famous books like The 10X Rule, and Axiom Award winning Sell or Be Sold. In addition to this, he also founded Cardone University, a popular sales training platform that has over 50,000,000 and growing users.It took Cardone only five years to completely change his entire life. With the right mindset and sufficient willpower, just imagine what five years could do for you.4. Why did Cardone choose to become a car salesman?A.To meet a superstar.

D.He put most of it in the bank.6. What does paragraph 5 mainly tell us about Cardone?A.His achievements. B.The plans for his company.C.His experiences of education. D.The reasons for his popularity.7. What can we learn from Cardone’s story?A.Failure is the mother of success.B.Investment is risky but rewarding.C.Making money calls for professional advice.D.Success requires determination and efforts.A team of researchers at the University of Cambridge have created an innovative floating device that uses solar power to transform polluted water or seawater into clean hydrogen (氢气) fuel and purified water.This device is particularly beneficial for areas with limited resources or without access to the electricity, as it can operate with any open water source and does not rely on external power sources. It takes its inspiration from photosynthesis, the process by which plants turn sunlight into food. However, unlike earlier versions of the “artificial leaf”, which could produce green hydrogen fuel from clean water sources, this new device operates from polluted or seawater sources and can produce clean drinking water-at the same time.“In remote or developing regions, where clean water is relatively scarce and the basic facilities necessary for water purification are not readily available, water splitting (分解) is extremely difficult,” said Ariffin Mohamad Annuar, a member of the research team. “The device that could work using polluted water could solve two problems at once: it could split water to make clean fuel, and it could make clean drinking water.”The device that can make clean fuel and clean water at once using solar power alone could help address the energy and the water crises facing so many parts of the world. For example, the indoor air pollution caused by cooking with “dirty” fuels, such as kerosene, is responsible for more than three million deaths annually, according to the World Health Organization. Cooking with green hydrogen instead could help reduce that number significantly.“It’s such a simple design as well: in just a few steps, we can build a device that works well on water from a wide vari ety of sources,” said Ariffin Mohamad Annuar. “In addition, the new device uses more of the sun’s energy. The light-driven process for making solar fuels only uses a small portion of the solar spectrum (光谱) —there’s a whole lot of the spectrum that goes unused.”8. What do we know about the new device?A.It can hardly produce clean hydrogen fuel.B.It needs a lot of power to function properly.C.It is not as convenient as the “artificial leaf”.D.It can turn polluted water into purified water.9. What does the underlined word “scarce” in paragraph 4 mean?A.Insufficient. B.Cheap. C.Available. D.Useless.10. Which word can best describe the new device?A.Costly. B.Environmentally-friendly.C.Outdated. D.Complex.11. Why does the author mention the example in paragraph 5?A.To stress the harm of air pollution to human beings.B.To predict how many people will buy the new device.C.To show the potential impact of the new device on the world.D.To explain the skills of selling the new device to the poor people.Recent research has found that Martian (火星的) soil contains all the essential nutrients necessary for growing rice, planetary scientist Abhilash Ramachandran of the University of Arkansas in Fayetteville, reported at the Lunar and Planetary Science Conference, providing new possibilities for agriculture on the Red Planet.The study, conducted by a team of researchers from the University of Arkansas in Fayetteville, tested simulated (模拟的) Martian soil to determine its suitability for growing rice. The researchers found that the soil contained all the essential nutrients needed for the crop to grow.However, it would be a bit challenging for the plants to survive in the soil that has perchlorate, a chemical that has been detected on Mars’ surface and can be poisonous to plants.The team grew rice plants in a Martian soil simulant primarily made of Mojave Desert basalt (玄武岩). However, the new-grown plants developed slighter shoots and thinner roots than the plants that grew from the potting mix. Even replacing just 25 percent of the simulant with a potting mix made a big difference, the team found.The team of researchers then conducted an experiment to grow rice in soil containing perchlorate. They used a wild rice variety and two genetically edited varieties, which were designed to stand up to environmental stressors such as drought, and tested them in Mars-simulated soil with and without perchlorate.The study revealed that a concentration of three grams of perchlorate per kilogram of soil resulted in no growth of rice plants. However, when the concentration was reduced to one gram per kilogram, one of the genetically edited lines successfully grew both a shoot and a root, while the wild variety was only able to grow a root.“We want to send humans to Mars but we cannot take everything there. It’s going to be expensive,” said Ramachandran. The discovery could be a game-changer for future missions to Mars, as it could enable astronauts to grow their own food on the planet, reducing the need for costly and complex resupply missions.12. How did the researchers conduct their study?A.By asking questions. B.By carrying out experiments.C.By making a case study. D.By referring to former studies.13. The gene-edited variety grows better in one kilogram of soil containing ______.A.one gram of perchlorate B.two grams of perchlorateC.three grams of perchlorate D.four grams of perchlorate14. Why did the researchers want to grow rice on Mars?A.To find a wonderful way to make money.B.To support the growing population on Earth.C.To help astronauts feed themselves on Mars.D.To enable people to eat new varieties of rice.15. What’s the best title for the text?A.What Should We Grow on Mars?B.How Did Martian Soil Change Over Time?C.People Are Likely to Live on Mars Years LaterD.Martian Soil May Have All the Essential Nutrients Rice NeedsWriting a poem is about observing the world within or around you. 16 , from love to loss to the gate at the old farm. Writing poetry seems difficult. However, with the right approach, you can write a poem that you can be proud to share with others.Pick a specific theme or idea. This can make it easier for you to narrow down what images and descriptions you are going to use in your poem. For example, you may decide to write a poem around the theme of love and friendship. 17 .Avoid cliché(陈词滥调). Your poetry will be much stronger if you avoid cliches, which are phrases that have become so familiar that they have lost their meaning. 18 . By doing so, your reader is surprised and attracted by your writing. If you feel a certain phrase or image is too familiar to your reader, replace it with a more unique one.19 . Poetry is made to be read out loud. So you should write your poem with a focus on how it sounds on the page. Pay attention to the structure of your poem and your word choice. Notice how each line of your poem flows into one another and how placing one word next to another creates a certain sound.Get feedback(反馈) from others. You can also share your poem with other poets to get feedback from them and improve your poem. 20 , where you discuss your poems with other poets and work on your poetry together. Or you may take a poetry writing class, where you work with an instructor and other poets to improve your writing.Urquhart finished running 1,402 kilometers over the course of 28 days in Antarctica, setting the record for the longest-ever run in a polar region.Australian Urquhart is an _________ mar athon runner.

细胞衰老英语作文

细胞衰老英语作文Title: Understanding Cellular Senescence: Implications and Mitigation Strategies。
Cellular senescence, the phenomenon where cells cease to divide and undergo functional changes as they age, is a crucial aspect of biological aging. This intricate process involves various molecular mechanisms and has significant implications for human health and disease. In this essay, we will delve into the intricacies of cellular senescence, its underlying mechanisms, its impact on aging, and potential strategies to mitigate its effects.At the core of cellular senescence lies the gradual accumulation of cellular damage and the activation of specific signaling pathways. One of the key mechanisms driving senescence is telomere shortening, where the protective caps at the ends of chromosomes progressively erode with each cell division. Once telomeres reach a critical length, cells enter a state of replicativesenescence, halting further proliferation.Apart from telomere attrition, cellular senescence can also be triggered by various stressors, including oxidative stress, DNA damage, and oncogene activation. These stressors activate signaling pathways such as the p53-p21 and p16INK4a-Rb pathways, leading to cell cycle arrest and the acquisition of a senescent phenotype.The consequences of cellular senescence extend far beyond the individual cells. Senescent cells secrete a myriad of pro-inflammatory cytokines, growth factors, and matrix metalloproteinases, collectively termed the senescence-associated secretory phenotype (SASP). The SASP not only perpetuates the senescent phenotype but also contributes to chronic inflammation, tissue dysfunction, and age-related pathologies.The impact of cellular senescence on aging and age-related diseases is profound. Accumulation of senescent cells is observed in various tissues and organs with advancing age, correlating with age-related functionaldecline and disease susceptibility. For instance, in the context of cardiovascular aging, senescent endothelialcells impair vascular function and promote atherosclerosis. Similarly, in neurodegenerative diseases like Alzheimer's, senescent glial cells contribute to neuroinflammation and neuronal dysfunction.Given the detrimental effects of cellular senescence, there is growing interest in developing strategies to mitigate its impact and promote healthy aging. One promising approach is the selective elimination of senescent cells, a concept termed "senotherapy." Several senolytic agents, such as dasatinib and quercetin, have shown efficacy in targeting and clearing senescent cells in preclinical studies. These compounds selectively induce apoptosis in senescent cells while sparing healthy ones, thereby rejuvenating aged tissues and ameliorating age-related pathologies.Moreover, interventions targeting the SASP, termed "senomorphics," hold therapeutic potential in modulating the detrimental effects of senescent cells. By dampeningthe pro-inflammatory and pro-tumorigenic components of the SASP, senomorphics could attenuate age-related inflammation and tissue dysfunction.In addition to pharmacological interventions, lifestyle factors such as diet, exercise, and stress management play a crucial role in modulating cellular senescence and promoting healthy aging. Caloric restriction, intermittent fasting, and dietary supplementation with anti-oxidants have been shown to mitigate cellular senescence and extend lifespan in various model organisms. Regular physical activity also exerts anti-senescent effects by promoting DNA repair, reducing oxidative stress, and enhancing mitochondrial function.In conclusion, cellular senescence is a multifaceted process that plays a central role in biological aging and age-related diseases. Understanding the underlying mechanisms of senescence and developing targeted interventions to alleviate its effects hold promise for promoting healthy aging and extending lifespan. By harnessing the power of senotherapy, senomorphics, andlifestyle modifications, we can strive towards a future where aging is not just prolonged but characterized by vitality and resilience.。

以花芽为题目的英语作文

以花芽为题目的英语作文Floral Buds: The Latent Blossoms of Spring.In the heart of winter, when the icy grip of frost cloaks the world in a monochrome tapestry, there lies a hidden promise of beauty waiting to unfold. Deep beneath the barren earth, encased within protective layers of bud scales, reside the floral buds—the dormant embryos of the springtime spectacle.Floral buds are the future flowers, miniature marvels awaiting the opportune moment to burst forth into vibrant life. They embody the essence of hope and renewal, concealed within the silent depths of winter's embrace. Their journey from dormancy to full bloom is a breathtaking symphony of nature's artistry.Anatomy of a Floral Bud.Floral buds are composed of a complex arrangement oftissues and structures that work in harmony to ensure the successful development of the flower. At the core lies the apical meristem, a cluster of undifferentiated cells responsible for the growth and development of all floral parts.Surrounding the meristem are the primordia, small mounds of tissue that will eventually give rise to the various flower structures—petals, sepals, stamens, and carpels. These primordia are arranged in a specific spiral pattern known as the floral formula, which determines the number and arrangement of each type of floral organ.The primordia are enclosed within protective layers of bud scales. These scales, often covered in a waxy or hairy coating, shield the developing flower from desiccation, cold temperatures, and mechanical damage. As the bud matures, the bud scales gradually soften and spread apart, allowing the flower to emerge.Dormancy and Environmental Cues.Floral buds enter dormancy during the unfavorable conditions of winter. This period of arrested development allows the buds to conserve resources and protect the delicate flower primordia from freezing temperatures.The release of buds from dormancy is triggered by a combination of environmental cues, primarily temperatureand photoperiod. As the days lengthen and temperatures rise, the buds sense the approaching spring and begin to break their winter slumber.The Miracle of Flowering.With the arrival of spring, the floral buds emerge from dormancy and embark on an extraordinary transformation. The bud scales unfold, revealing the vibrant colors andintricate patterns of the flower. The petals, initially tightly furled, gradually unfurl like delicate origami creations, showcasing their full glory.The stamens, bearing pollen grains, protrude from the center of the flower, ready to transfer their geneticmaterial to the carpels, the female reproductive organs.The carpels, consisting of the ovary, style, and stigma, await the arrival of pollen grains to initiatefertilization and seed production.The Purpose of Flowers.Flowers, the culmination of the floral bud's journey, serve a vital role in the plant's reproductive strategy. They attract pollinators, such as bees or butterflies,which carry pollen from one flower to another, ensuring genetic diversity and the production of new seeds.Seeds, carried by the wind or animals, disperse theplant's offspring to new locations, allowing the species to colonize new territories and adapt to changing environments. Flowers, therefore, are essential for the survival and propagation of plant species.Floral Buds in Literature and Art.Floral buds have long captured the imagination ofartists, writers, and poets. Their symbolism of hope, beauty, and renewal permeates various cultures and artistic expressions.In Japanese culture, cherry blossom buds, known as "sakura-tsubomi," are celebrated as a symbol of springtime and the ephemeral nature of life. The delicate pink buds are often depicted in paintings, poems, and traditional crafts, inspiring a sense of wonder and awe.In Western art, the floral bud has been used to symbolize purity, innocence, and the promise of new beginnings. Painters from the Renaissance to the present day have captured the beauty of floral buds in their still-life compositions and allegorical paintings.Conclusion.Floral buds are unassuming marvels, the silent precursors of springtime's glorious display. Hidden within their protective layers, they embody the promise of renewal and the extraordinary beauty that nature has in store. Asthey emerge from dormancy and burst forth into bloom, floral buds remind us of the cyclical nature of life and the indomitable spirit of nature. From their humble beginnings to their radiant blossoms, floral buds are a testament to the wonders that lie dormant, awaiting the right moment to reveal their full potential.。

JOURNAL OF THE Vol.40,No.4 WORLD AQUACULTURE SOCIETY August,2009 Compensatory Growth of Olive Flounder,Paralichthys olivaceus, Fed the Extruded Pellet with Different Feeding RegimesYoung Jin Cho and Sung Hwoan Cho1Division of Marine Environment and BioScience,College of Ocean Science and Technology,Korea Maritime University,Busan606-791KoreaAbstractThis study was performed to determine compensatory growth of juvenile oliveflounder fed the extruded pellet(EP)with different feeding regimes.Seven treatments with triplicates of differentfeeding regimes were prepared;αfish was daily fed for6d a week throughout8wk(8WF);αfish was starved for1wk and then fed for3wk twice[(1WS+3WF)×2];βfish was starvedfor2wk and then fed for6wk(2WS+6WF);χfish was starved for5d and then fed for9d four times[(5DS+9DF)×4];δfish was starved for10d and then fed for18d twice[(10DS+18DF)×2];εfish was starved for2d,fed for5d,starved for3d,and then fed for4d four times[(2DS+5DF+3DS+4DF)×4];andφfish was starved for4d,fed for10d,starvedfor6d,and then fed for8d twice[(4DS+10DF+6DS+8DF)×2],respectively.Total feeding daywas all same,36d except for control group(48d).Weight gain offlounder in the8WF treatment washigher than that offish in other treatments.And weight gain offlounder in the2WS+6WF treatmentwas higher than that offish in the(5DS+9DF)×4and(4DS+10DF+6DS+8DF)×2treatments.Feed consumption offlounder in the8WF treatment was higher than that offish experienced feeddeprivation.Feed efficiency ratio(FER),protein efficiency ratio(PER),and protein retention(PR)were not significantly different among treatments.Chemical composition of the whole body offish withand without liver,except for moisture content of liver,was not different among treatments.T3leveloffish in the8WF and2WS+6WF treatments was higher than that offish in the(5DS+9DF)×4treatment.It can be concluded that juvenile oliveflounder achieved better compensatory growth at6-wk refeeding after2-wk feed deprivation compared with that offish with different feeding regimes.And T3level offish seemed to partially play an important role in achieving compensatory growth.Oliveflounder,Paralichthys olivaceus,is one of the most commercially important marine finfish in Eastern Asia including Korea,Japan, and China.Therefore,many studies on the effective production offlounder have been conducted;dietary nutrient requirements(Lee et al.2000a,2000b;Kim et al.2002;Lee et al. 2002),alternative protein sources forfishmeal in the diet(Sato and Kikuchi1997;Kikuchi 1999),optimum feeding frequency(Lee et al. 2000b),and the feeding strategy(Cho and Lee 2002;Cho2005b;Cho et al.2006).The optimum periods for the growth of olive flounder were between the late spring and early autumn in Korea,however,red tide and cold-water mass frequently occurred in this period as well.Flounder are commonly starved to minimize mass mortality atfish farms during 1Corresponding author.the occurrence of red tide and cold-water mass, and it eventually resulted to the economical loss offish farmers due to a decrease infish production.Because feed cost and discharged water pollution source fromfish farms were directly related to the use of the diet,not only the nutritional and physiological status offish but also the environmental conditions directly affectingfish performance must be carefully considered atfish farms before the supply of feed tofish.Compensatory growth offish,which is rapid or faster than normal growth rate offish,result-ing from refeeding after undernutrition could be an applicably effectivefish culture technique in the occurrence of red tide and cold-water mass(Cho et al.2006).Compensatory growth offish was largely influenced by several fac-tors,such asfish size or age(Bilton and Robins 1973),feeding protocol(Jobling and Koskela©Copyright by the World Aquaculture Society2009505506CHO AND CHO1996;Rueda et al.1998;Gaylord and Gatlin 2000),nutrient levels in the diet(Gaylord and Gatlin2001),feeding regimes(Wang et al. 2000;Cho and Lee2002;Tian and Qin2003, 2004;Cho2005a,2005b;Cho and Jo2005; Cho et al.2006;Oh et al.2007),and so on. Also compensatory growth has been observed in most of the cold-,warm-,and tropical-water finfish species(Bilton and Robins1973;Quin-ton and Blake1990;Damsgaard and Dill1998; Rueda et al.1998;Gaylord and Gatlin2000, 2001;Wang et al.2000;Tian and Qin2003, 2004;Cho2005a;Cho and Jo2005).In the earlier studies(Cho2005b;Cho et al.2006),flounder achieved full compensatory growth whenfish were starved up to2wk in the8-wk feeding trials.The use of extruded pellet(EP)is highly rec-ommended in most of thefish farming because of easy observation of feeding activity,easy management,and minimal water pollution.And a short-term feed deprivation offish for grad-ing,transporting,and medicating frequently occurred around the year atflounder farming. Therefore,the purpose of this study is to deter-mine the possibility of compensatory growth of flounder with successive short-feed deprivation compared with that offish with long-term feed deprivation.Materials and MethodsFish and Experimental Conditions Juvenile oliveflounder was purchased from a private hatchery(Kyungbook,Korea)and accli-mated to the experimental conditions for2wk. During the acclimation period,flounder were fed the commercial EP twice a day.Fortyfloun-der averaging12.6g were randomly chosen and distributed to21–80Lflow-through tanks (water volume:150L)each.Water tempera-ture ranged from14.8to24C(mean±SD= 18.6±2.89C)and photoperiod followed natu-ral conditions.Theflow rate of water into each tank was9.7L/min,and aeration was supplied to each tank.Design of the ExperimentSeven treatments with triplicate of different feeding regimes were prepared:fish was daily fed for6d a week during8wk(8WF),which was used as a control group;αfish was starved for1wk and then fed for6d a week during 3wk twice[(1WS+3WF)×2];βfish was starved for2wk and then fed for6d a week during6wk(2WS+6WF);χfish was starved for5d and then fed for9d four times[(5DS+ 9DF)×4];δfish was starved for10d and then fed for18d twice[(10DS+18DF)×2];εfish was starved for2d,fed for5d,starved for3d, and then fed for4d four times[(2DS+5DF+ 3DS+4DF)×4];andφfish was starved for4 d,fed for10d,starved for6d,and then fed for 8d twice[(4DS+10DF+6DS+8DF)×2], respectively.Thus,total feeding day was all same,36d except for the control group(48d). The EP(Suhyup feed;52.0%crude protein and 11.0%crude lipid)was hand-fed to satiation twice(0900and1630h)a day as feeding schedules.Remaining EPs in each tank were collected in30min after feeding and deducted from total feed consumption.The experiment lasted for8wk.Analysis of Proximate Composition and BloodChemistry of FishFivefish from each tank at the end of the experiment were sampled for the chem-ical analysis.Analysis of proximate compo-sition of the whole body offish with and without liver was conducted based on AOAC (1990).Crude protein content was determined using the Kjeldahl method(Auto Kjeldahl Sys-tem,Buchi B-324/435/412,Switzerland),lipid content determined using the ether-extraction method,moisture content determined by dry-ing the sample in a dry oven at105C for24h,fiber content determined using automatic ana-lyzer(Fibertec,Tecator,Sweden),and ash con-tent determined using muffle furnace at550C for4h.Blood samples were obtained from the cau-dal vein of randomly chosen threefish from each tank by using a heparinized syringeCOMPENSATORY GROWTH OF FLOUNDER WITH DIFFERENT FEEDING REGIMES507after they were starved for24h and anes-thetized with MS-222at the concentration of 100mg/L.Plasma was collected after centrifu-gation(890g for10min),stored in freezer at–70C as separate aliquots for analysis of total protein,glucose,cholesterol,triglyc-erides(TG),glutamic oxaloacetic transaminase (GOT),and glutamic pyruvic transaminase (GPT),and enzymatically analyzed by using automatic chemistry system(HITACHI7180 and7600–210,Hitachi,Japan)based on the manual of Daiichi Pure Chemicals Co.Ltd (2005).In addition,total plasma T3(tri-iodothyronine)and T4(thyroxine)hormones of fish at the end of feeding trial and starved fish every week throughout the feeding trial were analyzed by radio-immunoassay(Gamma Counter,Cobra II,Packard,USA)using Coat-A-Count kit(DPC,Los Angeles,CA,USA).Statistical AnalysisOne-way ANOV A and Duncan’s multiple range test(Duncan1955)were applied to detect the differences among treatments by using SAS Version9.1(SAS Institute,Cary,NC,USA).Results and DiscussionSurvival(%),weight gain(g/fish),and spe-cific growth rate(SGR)of oliveflounder fed the EP with different feeding regimes are given in Table1.Survival ranging from98.3to 100%was not significantly(P>0.05)differ-ent among treatments.However,weight gain of flounder in the control group(8WK),in which fish were fed for48d during8wk without star-vation,was significantly(P<0.05)higher than that offish in all other treatments,in whichfish were fed for36d with successive starvation and feeding regimes during8wk in this study.Sim-ilar trend that weight gain of Atlantic halibut, Hippoglossus hippoglossus,fed daily for99d (control)was higher than that offish fed for 63–67d with different starvation and feeding regimes(Heide et al.2006).Difference in partial compensatory growth offlounder in the2WS+6WF treatment in this study and full compensatory growth offish in the2WS+6WF treatment in the previous studies(Cho2005b;Cho et al.2006)could be resulted from the difference infish size in those studies;smallfish(12.5g)in this study versus largefish16(Cho et al.2006)and54g(Cho 2005b).Smaller sizefish is more susceptible to feed deprivation than largerfish,so smaller flounder did not compensate fully in the same feeding regime in this study.The possibility of full compensatory growth offish varies depend-ing onfish species,fish size,feeding proto-col,water temperature,feed nutrients,dura-tion of feeding trial,etc.(Bilton and Robins 1973;Jobling and Koskela1996;Rueda et al. 1998;Gaylord and Gatlin2000,2001;Wang et al.2000;Tian and Qin2004;Cho2005a, 2005b;Cho and Jo2005).However,weight gain offlounder in the2WS+6WF treatment was significantly(P<0.05)higher than that offish in the(5DS+9DF)×4and(4DS+Table1.Survival(%),weight gain(g/fish),and

fish in the (1WS +3WF )×2,(10DS +18DF )×2and (2DS +5DF +3DS +4DF )×4treatments.A similar result was reported in Atlantic halibut (Heide et al.2006)in that one initial longer period of starvation achieved clear compensatory growth over two to three shorter intermediary periods.Also,SGR of flounder in the 2WS +6WF treatment was sig-nificantly (P <0.05)higher than that of fish in the (5DS +9DF )×4and (4DS +10DF +6DS +8DF )×2treatments,but not signifi-cantly (P >0.05)different from that of fish in other treatments.These results probably indi-cated that one initial long period of feed depri-vation (2wk)is preferred to achieve better compensatory growth of flounder over the suc-cessive short period of feed deprivation for aquaculture purposes.Although flounder accept EP as well,its application is very limited in flounder farm-ing in reality as a result of poor growth of fish probably resulted from its swollen diges-tive tract and mistrust of flounder farmers on EP,which is still controversial.Besides,com-pensatory growth of flounder fed the dry pellet instead of EP with same feeding strategy in this study came out with different result from this study and will be reported in another study.Feed consumption (g/fish),feed efficiency ratio (FER),protein efficiency ratio (PER),pro-tein retention (PR),condition factor (CF)and hepatosomatic index (HSI)of olive flounder fed the EP with different feeding regimes are shown in Table 2.Feed consumption of floun-der in the 8WF treatment was significantly (P <0.05)higher than that of any fish expe-rienced feed deprivation in other treatments,probably resulting to poorer growth of fish in the latter than in the former.Weight gain of flounder seemed to be proportionally affected by feed consumption of fish in this study.Hyperphagia is one of the primary mechanisms leading to compensatory growth of fish after feed deprivation and was commonly accompa-nied especially when fish achieved full compen-satory growth

was significantly(P<0.05)higher than that offish in the(4DS+10DF+6DS+8DF)×2treat-ment,but not significantly(P>0.05)different from that offish in other treatments.The low-est feed consumption offlounder in the(4DS+ 10DF+6DS+8DF)×2treatment resulted to the poorest weight gain offish in this study. FER ranging from1.11to1.26,PER rang-ing from1.98to2.25,and PR ranging from 34.2to39.8offlounder were not significantly (P>0.05)different among treatments.Simi-larly,FER and PER of Atlantic halibut expe-rienced feed deprivation were not affected by feeding regimes(Heide et al.2006).Although fish achieved compensatory growth,improve-ment in feed efficiency was not observed(Wang et al.2000;Tian and Qin2003).HSI offlounder in the(5DS+9DF)×4and(4DS+10DF+6DS+8DF)×2treat-ments,in whichfish achieved poor weight gain, was significantly(P<0.05)higher than that offish in the8WF,(1WS+3WF)×2,2WS+ 6WF,and(2DS+5DF+3DS+4DF)×4treatments,but not significantly(P>0.05) different from that offish in the(10DS+ 18DF)×2treatment.Similarly,HSI offloun-der decreased in proportion to weight gain of fish whenfish were refed after feed depriva-tion(Cho2005b).However,CF offlounder in the(10DS+18DF)×2treatment was signifi-cantly(P<0.05)higher than that offish in the (1WS+3WF)×2and(2DS+5DF+3DS+ 4DF)×4treatments,but not significantly(P> 0.05)different from that offish in other treat-ments in this study.However,unlike this study, HSI and CF offish were the good indices to indicate the possibility of compensatory growth offish and decreased rapidly with feed depri-vation period and increased rapidly with subse-quent refeeding(Gaylord and Gatlin2000;Cho et al.2006).Proximate composition of the whole body offish with and without liver,except for moisture content of liver,was not signifi-cantly(P>0.05)different among treatments (Table3).Moisture content of liver infish in the2WS+6WF and(2DS+5DF+3DS+ 4DF)×4treatments was significantly(P< 0.05)higher than that offish in the8WF,Table3.Proximate composition(%)of oliveflounder at the end of the feeding trial1.Whole body

not affected by feeding regimes with short-and long-term starvation and refeeding (Cho and Lee 2002;Cho 2005b;Cho et al.2006;Heide et al.2006).Blood chemistry of olive flounder at the end of the 8-wk feeding trial is presented in Table 4.Plasma protein,glucose,TG,GOT,GPT,and T 4levels of flounder were not signif-icantly (P >0.05)different among treatments.However,cholesterol level of flounder in the 8WF and (10DS +18DF )×2treatments was significantly (P <0.05)higher than that of fish in the (5DS +9DF )×4,(2DS +5DF +3DS +4DF )×4,and (4DS +10DF +6DS +8DF )×2treatments,but not significantly (P >0.05)different from that of fish in the (1WS +3WF )×2and 2WS +6WF treatments.T 3level of flounder in the 8WF and 2WS +6WF treatments was significantly (P <0.05)higher than that of fish in the (5DS +9DF )×4treat-ment,which was the lowest.A trend toward an increased T 3level of fish in proportion to weight gain of fish,which was the highest T 3level in the 8WF treatment,followed by fish in the 2WF +6WF treatment and relatively low for fish in the (4DS +10DF +6DS +8DF )×2treatment in this study,probably indicated that T 3level of fish played an important role in achieving compensatory growth of fish after feed deprivation and partially agreed with Van der Geyten et al.’s (1998)study.Eales (1988)explained that inhibition of thyroid function appeared to be one of the most consistent endocrine responses to feed deprivation,and feed deprivation resulted to the decrease in growth and circulating levels of the T 3and T 4.Similarly,feed restriction affected the thyroid function.Circulating T 3level correlated with the weight gain of red drum,Sciaenops ocella-tus ,at lower feeding ratio levels,actually reach-ing maximum levels at a feeding ratio below that yielding maximal weight gain,whereas T 4level did not differ among fish at different feed-ing ratios (Mackenzie et al.1993).However,in this study,it was difficult to explain why the lowest T 3level was observed in flounder inT a b l e 4.P l a s m a c h e m i s t r y o f o l i v e flo u n d e r a t t h e e n d o f t h e 8-w k f e e d i n g t r i a l .1P l a s m a c h e m i s t r yG l u c o s e C h o

with the least feed consumption.Gaylord et al. (2001)reported that plasma thyroid hormone following realimentation minimized the effects of feed deprivation on growth and feed effi-ciency of channel catfish subjected to the3-d feed deprivation treatment when compared with longer periods(5-and7-d feed deprivation). In considering these results,it can be con-cluded that juvenile oliveflounder achieved better compensatory growth at6-wk refeeding after2-wk feed deprivation compared with that offish with different feeding regimes.And T3 level offish seemed to partially play an impor-tant role in achieving compensatory growth whenfish were refed after feed deprivation.AcknowledgmentsThis work was supported by the Korea Research Foundation(KRF)(KRF-2006-005-J00501)and research fund(Project no. #20088033-1)from the Ministry of Land, Transport and Maritime Affairs,Republic of Korea.Literature CitedAOAC(Association of Official Analytical Chemists).1990.Official methods of analysis,15th edition.Asso-ciation of Official Analytical Chemists,Arlington, Virginia,USA.Bilton,H.T.and G.L.Robins.1973.The effects of starvation and subsequent feeding on survival and growth of Fulton channel sockeye salmon fry.Journal of Fisheries Research Board of Canada30:1–5.
