人工诱导青虾成熟和产卵

Induced Maturation and Spawning of Macrobrachiurn nipponense

本文研究了青虾催产的方法。采用注射孕酮;切除眼柄和激光照射复跟等技术,人工诱导青虾成熟和产卵,效果明显。并且孵化出的幼体与自然成熟的卵孵化出的幼体在生长上没有显著差异。

Several methods for induced spawning of Macrobrachium nipponense were studied. Obvious effects were obtained while techniques of progesterone injection, laser radiation on the compound eye and ablation of eye stalk were adopted to induce maturation and spawning of the prawn. No significant difference in growth was observed between the larvae artifieially, induced and those hatched out from the eggs naturally laid.
