| 英文摘要 | The bottom aquaculture of yesso scallop(Pa tinopecten yessoensis)has developed rapidly in the north of Yellow Sea,China,but not without accompanying productivity problems.We,therefore,conducted field surveys to investigate factors related to growth and mortality rates of bottom-cultured scallops after release.Specifically,we focused on the effects of total antioxidant capacity(TAOC)and three key enzymes involved in antioxidant and metabolic function:glutamic pyruvic transaminase(GPT),lactic dehydrogenase(LDH),and superoxide dismutase(SOD).Across summer and winter,we also measured the relative mRNA expression of GPT and SOD to understand their seasonal variation in the scallops,along with how such variation correlated to growth and mortality.Results show that bottom cultured scallops experienced mass mortality during the first six months post-release.During winter(December),scallops grew more rapidly and suffered less mortality than in summer(August).The observed lower performance probably resulted from less advantageous environmental factors during the summer seasons,such as high temperature and low dissolved oxygen.These environmental stressors enhance protein consumption while decreasing energetic resources in scallops.Furthermore,scallops in summer exhibited high antioxidant levels that probably competed for energy with process integral to growth and survival.These negative factors combined to elevate mortality rates.In conclusion,we provided evidence suggesting correlations between metabolic/antioxidant activity and growth and mortality of bottom-cultured yesso scallops.These correlations implied us an accurate method to estimate the performance of bottom culture system.Suggestions about innovative aquaculture techniques were also discussed in the study.Our results might provide a possible guideline to the improvement of bottom culture techniques for this commercially valuable seafood species. |
