为了开发利用沼泽,我们于1988～1989年在黑龙江省宝清县进行了沼泽地养鱼试验。试验池面积35亩(水源为沼泽性河水),每亩放养体重25～60克的鲤鱼种及草鱼种共150～200尾、体长13.5～15厘米的鲢、鳙鱼种共10～20尾,经70～80天的饲养,出池规格都在体重0.4公斤以上,其中37％的个体达到0.9～1.1公斤。两年共产成鱼3689公斤,获纯利5315元。在沼泽地这种非水非陆的特殊环境下养鱼,除进行科学的饲养管理工作外,更重要的是建造适合沼泽环境的鱼池。这方面我们
In order to develop and utilize swamps, we carried out marshland fish culture experiments in Baoqing County, Heilongjiang Province from 1988 to 1989. The test pond area is 35 mu (water source is swamp river), and carp species and grass carp species weighing 25-60 grams per mu are 150 ~ 200, silver carp and bighead carp with 13.5-15 cm body length are 10-20 , After 70 ~ 80 days of breeding, the size of the pool are more than 0.4 kg weight, of which 37% of the individual reached 0.9 to 1.1 kg. Two years a total of 3689 kilograms of fish, net profit of 5315 yuan. In addition to scientific farming and management, it is even more important to fish fish ponds in wetlands, which are non-aqueous and non-land-based fish farms. We are in this area
