幼鱼,是鱼类捕捞资源补充的直接来源,也是鱼类养殖业的天然苗源。因此,进行幼鱼调查,可为鱼类资源估计及其长期预报提供科学依据;也能为渔业繁殖保护区的规定、新捕捞对象的探索和鱼类天然苗源的发掘等提供重要资料。我国海域辽阔,系统开展这项研究工 Juveniles are a direct source of supplemental fishing resources for fish and are a natural seedling source for fish farming. Therefore, the survey of juveniles can provide a scientific basis for the estimation of fish resources and its long-term prediction. It can also provide important information for the provisions of the fisheries breeding reserve, the exploration of new fishing targets and the excavation of natural fish seed sources. China’s vast sea, the system to carry out the research workers
