摘      要：Growth and energy budget of marine amphipod juvenile Eogammarus possjeticus at different temperatures(20℃,24℃,26℃,28℃,30℃,32℃ and 34℃)were investigated in this *** results showed that the cumulative mortality rate increased significantly with rising temperature(p0.01),and exceeded 50%after 24 h when temperature was above 30℃.With the temperature increasing from 20℃ to 26℃,the ingestion rate and absorption rate increased,but decreased significantly above 28℃(p0.01),indicating a decline in feeding ability at high *** specific growth rate increased with rising temperature,but decreased significantly(p0.01)after reaching the maximum value at 24℃.Similarly,the oxygen consumption and ammonia emission rates also showed a trend of first increase and then ***,the O:N ratio decreased first and then increased with rising temperature,indicating that the energy demand of *** juvenile transferred from metabolism of carbohydrate and lipid to *** the energy distribution of amphipods,the proportion of each energy is *** rising temperature,the ratio of the energy deposited for growth accounted for ingested gross energy showing a trend of decrease,while the energy lost to respiration,ammonia excretion,and feces accounted for ingested gross energy being showed a trend of *** seemed that rising temperature increased the metabolism and energy consumption of the amphipods and,meanwhile,decreased the energy used for growth,which may be an important reason for the slow growth and small body size of the amphipods during the summer high-temperature period.
