摘要
本文论述了海洋游虾类有关生物学问题的研究进展。(1)叙述了浮游虾类的产卵和幼体发育期。讨论了它们的繁殖方式和环境之间的关系。提出了虾类的繁殖朝着产较多较小的卵或较少较大的卵两个不同的方向发展,是以不同的繁殖方式达到相同的效果,即节省繁殖能量、适应环境和保存种族的观点。(2)讨论了蜕皮增长和蜕皮间隔期及其影响因子。叙述了某些虾类的生长速度、寿命和死亡。(3)叙述了浮游虾类的行为例如集群和昼夜垂直移动。讨论了引起昼夜垂直移动的主要外界因子。介绍了Omori的垂直移动分组。(4)叙述了海洋浮游虾类生物量的水平分布与垂直分布。(5)讨论了浮游虾类的食物关系。
This paper is a review on the biology studies advances of pelagic and planktonic shrimps in the Ocean and its neighbour sea regions.Spawning types and the numbers of larval stages in each phase for different groups in the shrimps have been discribed. The relationship between the way of reproduction and environment conditions has been discussed. The auther in this paper presented a new viewpoint that the reproduct types of the shrimps may evolve into having greater numbers of smaller eggs or having fewer numbers of larger eggs, which achieved similar effects, that is, reduce energ consume for reproduction, adaptation to environment and keep continuity for the species with different reproduction ways.The molt increment and the intermolt period, and factors influenced them were disscussed. The growth rate, life-span and mortality for some the shrimps were discribed.The behaviour movements e. g. shoaling and diurnal verticil migration by pelagic and planktonic shrimps have been discribed. The exogenous main factors caused the migration have been discussed. It has been recommended that divided into groups for the migration by Omori.Level and vertial distribution of bimass of pelagic and planktouic shrimps has been discribed.The food relationship for the shrimps has been discussed.
