为了研究南美白对虾不同养殖密度池塘的水质变化规律,并对不同养殖面积、养殖密度和经济效益的关系进行分析,2012年5—8月,通过对不同养殖密度南美白对虾养殖池水质周期性连续监测,得到养殖水体水质污染状况及一般规律。在试验设置的养殖密度下,各个养殖池的水质指标均在对虾健康生长合适范围值内。随着养殖密度的增加,水体中TN、TP、NH3-N、NO2-N的含量逐渐增加,CODMn无明显的变化规律;同时对不同养殖密度和养殖面积与经济效益的关系进行了统计分析。结果表明,养殖面积为0.067 hm2,养殖密度为105~150万/hm2的小规模养殖模式效益最高。
Abstract
In order to study the rule of water quality changes under different breeding densities and to analyze the relationship between different breeding area, different breeding densities and economic benefit, the author studied the general pollution rule in white leg shrimp Penaeus vannamei ponds by monitoring different breeding density ponds continuously from May to August in 2012. Under the experimental testing density, the water qualities were in the normal range of shrimp for healthy growth. The contents of TN, TP, NH3-N and NO2-N increased with the increasing densities while the CODMn had no significant changes. The author studied the relationship between different breeding densities and area and economic benefit, and the results showed that area of 0.067 hm2 and breeding density of 1050 to 1500 thousand individuals per 0.067 hm2 were the best model for small-scale shrimp culture.
