湖泊网围养鱼是近几年兴起的新型渔业生产方式。是改革传统湖泊渔业利用方式的一项突破。随着网围养鱼技术的推广应用,我国的湖泊渔业取得了长足的进步。但由于网围养鱼历史较短,各地生产经营水平不同,总的还存着单产水平低,群体增重倍数不高,经济效益不高的问题。如何提高湖泊网围养鱼的单产水平。提高经济效益,这是湖泊网围养鱼进一步推广应用中急需解决的课题。鉴于以上情况,我们在滆湖进行了湖泊网围养殖高产技术的研究,现将试验情况介绍如下。材料和方法试验条件:本研究以滆湖南部的官林围养场、丰义乡围养场为试验点,供试验用网围建在湖底平坦,远离航道处;平均水深1.5米,底质为粘土,流速一般为0.1米/秒;水质良好,溶解氧0.81—10.35毫克/升,PH值8.04～8.36。试验规模:本研究主要以30亩以下面积为
Fish culture around the lake is a new type of fishery production that has emerged in recent years. It is a breakthrough in reforming the utilization of traditional lake fisheries. With the popularization and application of net fish farming technology, China’s lake fishery has made great strides. However, due to the short history of net fish farming around the different levels of production and management, the total still exist low yield levels, population weight gain is not high, the problem of low economic returns. How to improve the yield of fish around the lake net? Improve economic efficiency, which is the urgent need to address the issue of further promotion and application of fish around the lake. In view of the above, we conducted a lake lacustrine breeding high-yielding technology research, test conditions are as follows. MATERIALS AND METHODS Test conditions: In this study, Guilin surrounding farms in Fenghuang Lake, Fengye surrounding farms as a test point for the test net built at the lake flat, far away from the waterway; average depth of 1.5 meters, the substrate For the clay, the flow rate is generally 0.1 m / s; good water quality, dissolved oxygen 0.81-10.35 mg / l, PH value of 8.04 ~ 8.36. Test scale: The main area of this study is 30 mu
