摘要
本文根据生产性试验,就河蟹土池人工育苗中培育管理与亲蟹成活率的关系、影响幼体成活率的主要因素及淡化对出池蟹苗成活率的影响等有关技术问题进行了初步探讨,并提出了若干改进措施。
In this paper some technical problems are preliminarily discussed about relations ketween rearing managements and survival rates of parent crabs, major factors influencing survival rates of larvae of E.sinensis and effects of dilution of sea-water on survival rates of megalopa larvae after restocked in freshwater according to the results of production experiments during March to May, 1994.At the same time proper measures to raise success rate of crab propagation in earth ponds are put forward.
