2000～2001年在6座中型低坝水库中,开展网拦养殖河蟹试验。2000年网拦养蟹面积133 3hm2,投放豆蟹40万只,扣蟹30万只,年底起捕成蟹1 5万kg,销售额147 6万元,实现利税107 9万元,水库分成30万元。2001年推广网拦面积346 7hm2,起捕成蟹2 75万kg,水库分成60万元。为丘陵地区低坝类中型水库充分利用其水土资源发展水利渔业,提供了一种可靠的借鉴。
From 2000 to 2001 in six medium-sized low-dam reservoirs, to carry out net barbed culture crab test. In 2000, the net area of crabs was 133 3 hm 2, 400,000 bean crabs and 300,000 crabs were crabs. From the end of the year, 15,000 kg of crabs were crabrated and the sales amount was 14.7 million yuan. The profits and taxes were 10.79 million yuan, and the reservoir was divided into 30 Million. In 2001, a total area of 346,7hm2 was popularized and a total of 2.75 million kg of crabs were caught. The reservoir was divided into 600,000 yuan. It provides a reliable reference for the development of water conservancy and fishery for low dams medium-sized reservoirs in hilly areas by making full use of their water and soil resources.
