测定了中华绒螯蟹 期、 期氵蚤状幼体及仔蟹 (壳宽 :0 .4 42± 0 .0 3 4 cm)的瞬时耗氧率 ,对瞬时耗氧率和溶解氧 (DO)作相关分析。结果表明 ,河蟹幼体的不同发育阶段、处于不同环境中的个体 ,其瞬时耗氧率不随溶解氧的升降而升降。同时测定了处于不同发育阶段河蟹幼体所处水环境的瞬时耗氧率以及各自的窒息临界点和半致死点 The instantaneous oxygen consumption rate of mitochondrial Eriocheir sinensis, Ephemeral fleas and larvae (shell width: 0.42 ± 0.304 cm) were measured. The instantaneous oxygen consumption rate and DO related analysis. The results showed that the instantaneous oxygen consumption rate of crayfish larvae in different developmental stages and in different environments did not rise and fall with the rise and fall of dissolved oxygen. At the same time, the instantaneous oxygen consumption rate of water environment of crab larvae at different developmental stages and their respective critical and semi-lethal points of asphyxia
