摘要
通过对河沟养殖情况的调查分析,结合河沟生态特点,认为可将河沟划分为宽浅型和窄深型两种类型,浅滩面积占40%以上的宽浅型河沟养殖河蟹效果较佳,应侧重养蟹;浅滩面积低于40%的窄深型河沟养殖河蟹则不理想,应侧重养鱼。
Considering the ecological characteristics, by analyzing effects of crab culture in river-channel,the river-channel could be divided into two types, wide-shallow and narrow-deep. The river-channels with over 40% of wide-shallow area were suitable for crab culture and the narrow-deep with below 40% of wild-shallow area were suitable for fish culture.
