海水池塘多营养层次生态混养模式与技术

Multi-trophic ecological mixed culture model and technology of the seawater ponds

根据生态学原理,将鱼、虾、贝合理搭配在一起,进行了多营养层次生态混养模式和海水池塘养殖水质调控相结合的综合调控技术,使得养殖水体中的非离子氨浓度NH 3≤0.02 mg/L,无机氮浓度(以N计)≤0.5 mg/L,水质稳定;池塘养殖年亩产值在16000元以上,经济效益提高50%以上,达到了营养物质高效利用、养殖效果显著提高的目的。

According to the principle of ecology,fish,shrimp and shellfish were reasonably matched together,and the comprehensive regulation technology combining the multi-trophic level ecological mixed culture mode with the water quality control of seawater pond culture was carried out.The water quality was stable with the concentration of non-ionic ammonia NH 3≤0.02 mg/L and the concentration of inorganic nitrogen(in terms of N)≤0.5 mg/L.The annual per-mu output value of pond culture is more than 16000 yuan,the economic benefit is increased by more than 50%,and the purpose of efficient utilization of nutrients and significant improvement of breeding effect has been achieved.
