近5年来(1981～1985),日本海区最重要的商品蟹之一三疣梭子蟹(短尾类、十足目),每年采扑量为4100～5600吨,其产值为60～80亿元。为了增加梭子蟹资源,1985年在日本海域放流稚蟹2700万尾。研究蟹幼体阶段的代谢,不仅可在人工养殖条件下合理的培育稚蟹,而且可在潮间带和浅海自然条件下,研究蟹的生活习性;可通过耗氧率的测定估计蟹的代谢损失及其它生物效率。为了提高蟹的人工培育技术,某些学者曾测定了蟹幼体的耗氧量。森冈泰启测定过溞状1期幼体的耗氧量,北岛力等曾测定从溞状1
In the recent 5 years (1981 ~ 1985), one of the most important commercial crabs in the Japan Sea, Portunus trituberculatus (short-tailed and deciduous) has an annual output of 4,100 to 5,600 tons and an output value of 6 to 8 billion yuan. In order to increase the resources of the shuttle crabs, in 1985, 27 million young crabs were released into the sea of Japan. Studying the metabolism of larvae in crab larvae can not only cultivate crabs properly under the conditions of artificial breeding, but also study the habits of crabs under the natural conditions of intertidal zone and shallow sea. The metabolic loss of crabs can be estimated through the determination of oxygen consumption rate And other biological efficiency. Some scholars have determined the oxygen consumption of crab larvae in order to improve the artificial cultivation of crabs. Morioka Tai Kai has been measured over the ridges of a larvae of oxygen consumption, Kitajima force had been determined from the 溞 1
