     It is preferable to start induced spawning in the early of middle of March (water temperature over 10℃),and the pond area is about 1000 m2.The stocking density of parent crabs should be 750 kg/10-11ha,with a sexual ratio of 2 ̄3(female): 1(male). The male crabs should be moved out timely when most of the females are berride.

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.

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。

it is frequently occurred in mitten crab breeding that earlier zoeas (Zoea1 and Zoea 1 ) are parasitized by Zoothamnium sp., resulting in sudden death because of bacterial or virus infection. The authors conducted experiments to kill Zoothamnium sp. by applying Malachite green. Nystatinum,chloromycetin and potassium permanganate, and the results showed that Malachite green and Nystatinum were the best in killing the parasites. However,based on the effect of zoea disease prevention and treatment, the authors...

Nystatinum,chloromycetin and potassium permanganate, and the results showed that Malachite green and Nystatinum were the best in killing the parasites. However,based on the effect of zoea disease prevention and treatment, the authors emphasized the importance of eaflier prevention and treatment, which should be started from the stage of temporary rearing of parent crabs, the pathogen carriers.

在河蟹育苗中常见早期溞状幼体(ZⅠ、ZⅡ)被聚缩虫(Zoothamniumsp)寄生引起细菌性或病毒性感染,造成突发性死亡。作者用孔雀绿、制霉素、氯霉素、高锰酸钾等药物对聚缩虫进行杀灭试验,结果显示以孔雀绿和制霉素的杀虫效果最好。但从早期 状幼体的病害防治效果来看,由于越冬亲蟹是病原体的携带者,因此作者强调防治工作必须从亲蟹暂养时做起,立足于早防早治;且以多种药物综合性措施为妥。

Induced spawning and cultivation of berried crab are two important production links in artificial breeding of mitten crab,which are directly related to the successful hatchery work.

河蟹人工育苗中亲蟹促产及抱卵蟹培育是关系到育苗成效的两个重要生产环节。作者通过多年来的生产性试验,亲蟹的抱卵率和抱卵蟹成活率均达90%以上。促产处理宜在3月上中旬进行(水温在10℃以上),促产地面积在1000m2上下,投放亲蟹密度为750kg/10-1公顷,雌雄性比掌握在2~3:1,待绝大多数雌蟹抱卵后应及时将雄蟹捕出。抱卵蟹培育的关键是防逃、合理投饲及水质管理。
