济宁市任城区地处鲁西南,南临我国北方最大的淡水湖——南四湖。滨湖、涝洼地、煤矿塌陷水域资源丰富。全区拥有各类宜渔资源1.33万hm~2(20万亩),133.3 hm~2(2000亩)以上的水域类型有20处,这些水域均为封闭式水域。但由于各种因素,使这些水域的经济鱼虾类急剧衰竭。为进一步探讨大水面经济鱼虾类的增养殖技术,2005年我们承担了区科技局下达的“666.7 hm~2(万亩)青虾增养殖技术研究”项目,经过一个生产周期的养殖试验,达到预期效果,超额完成项目下达的各项经济技术指标。现将试验情况介绍如下:
Jining city is located in the southwest of Shandong Province, south of China’s northern largest freshwater lake - Nansi Lake. Lakes, waterlogging depression, coal mine collapsed waters rich in resources. There are 13,300 hm ~ 2 (200,000 mu) of all kinds of suitable fishery resources in the region and 20 types of waters above 133.3 hm ~ 2 (2000 mu), all of which are enclosed waters. However, due to various factors, economic fish and shrimps in these waters have been rapidly depleted. In order to further explore the aquatic economic fish and shrimp aquaculture technology, in 2005 we assumed the District Science and Technology Bureau issued “666.7 hm ~ 2 (mu) of aquaculture technology research” project, after a production cycle of farming Test, to achieve the desired results, over the completion of the project issued by the economic and technical indicators. Now the test situation is as follows:
