摘要
本文介绍了一种全新的河蟹土池育苗方法。这种方法的优点在于河蟹育苗全程不投喂人工饵料。布苗前培养藻类,当藻类浓度较大时开始布苗,而后接种轮虫。在以后的培养过程中,通过施有机肥和无机肥调控饵料状况,使蟹苗自始至终有足够的饵料。结果显示,在5个试验池塘中仅有一个池塘达到了预期效果,其余4个池塘效果不好。用人工调控饵料生物的方法进行河蟹土池育苗技术还需要进一步完善。
A new method of artificial breeding of Mitten crab in earthen ponds has been introduced in the paper.The advantage of this method is that it need not feed on artificial diet in the course of breeding of Mitten crab.Before breeding,algal should be cultivated,and when algal concentration is high,rotifer should be inoculated.The situation of diet that provides enough diet for crab larvae is regulated by fertilized.The results show that there is only one pond that obtained expected effects in five ponds,but oth...
