经过本地近几年的实践表明,成鱼、龙虾、水芹轮作养殖,既能最大限度地利用鱼池闲置期,增加有效产出,又可提高池塘养殖的经济效益。此种养殖模式能合理地利用水产动、植物的生长期规律,充分挖掘水体生产潜力,是水产养殖结构调整的一个可行模式,具有广阔的发展前景。1池塘条件池塘面积为0.8 hm~2(12亩),长方形,东西走向为佳,水深2～2.5m,塘埂宽度3～5m;池塘坡比1:3以上,池
After local practice in recent years shows that adult fish, lobster, water celery crop rotation, both to maximize the idle period of fish ponds to increase effective output, but also improve the economic benefits of pond culture. This aquaculture model can reasonably make use of the law of growth of aquatic animals and plants and fully exploit the potential of water production, which is a feasible mode for aquaculture structural adjustment and has broad prospects for development. 1 pond conditions The pond area of 0.8 hm ~ 2 (12 acres), rectangular, east-west trend is better, the depth of 2 ~ 2.5m, pond width 3 ~ 5m; pond slope ratio of 1: 3 above, pool
