应用耕水机养殖南美白对虾的试验

为探索一条新的水产养殖途径，该文利用耕水机进行南美白对虾养殖对比试验。在一个养殖周期内对溶解氧、温度、pH值和亚硝酸盐等水环境因子及南美白对虾生长情况、品质和经济效益进行了分析研究。试验结果表明：与非耕水机养殖比较，使用耕水机能够提高水体溶解氧均匀度和温度均匀度，增加池塘溶解氧含量；维持水体pH值在7.6～8.9之间；降低水体亚硝酸盐含量；对虾生长速度快且品质优良；节约耗电量56.9%、饵料15.5%、药费45.4%；提高单位面积产量20.1%。试验和分析结果证明使用耕水机能够改善水体环境，降低养殖成本，增加养殖收入，有较高的实际应用价值。

Experimental study on applying biofan to cultivate Penaeus vannamei

In order to explore a new way in aquaculture, a Penaeus vannamei comparative test was conducted by using Biofan in this paper. In one breeding cycle, water environmental factors such as dissolved oxygen, temperature, pH and nitrite, Penaeus vannamei growth and quality and economic efficiency were analyzed. The results show that comparing with aquaculture without biofan, the method improves water dissolved oxygen uniformity, temperature uniformity and increases the dissolved oxygen content of the pond; maintains the water pH value between 7.6-8.9; reduces the nitrite content in water; improves the Penaeus vannamei growth speed and quality; saves 56.9% on power consumption, 15.5% on bait, 45.4% on drug; increases yield by 20.1% per unit area. Test and analysis results showed that using Biofan can improve water environment, reduce aquaculture costs and increase aquaculture production and income, so it has high value of practical application.
