本文报导了以海捕日本对虾进行人工越冬,然后切除雌虾单侧眼柄,投喂优质饵料,控制适当的生态条件,通过精心的管理,促进日本对虾性腺成熟并培育出虾苗的试验过程。日本对虾越冬成活率为93.3％,性腺促熟率为86.6％,交配率为75.9％。眼柄切除后12天即进入产卵高峰,出苗量为9.6万尾/m~3,无节幼体到仔虾成活率为69.0％,育出日本对虾苗量145.5万尾。

This article reports on the experimental process of catching Japanese shrimp by sea over artificial wintering, then cutting off the unilateral eyelids of females, feeding high-quality bait, controlling appropriate ecological conditions, and carefully managing gonadal maturation and breeding of shrimp . Japanese winter shrimp survival rate was 93.3%, gonadal maturation rate of 86.6%, mating rate of 75.9%. 12 days after excision of the eyelid, it reached the peak of spawning. The amount of emergence was 96,000 / m 3, the survival rate of nauplius to larvae was 69.0%, and the number of Japanese shrimp was raised to 1,455,000.
