三湖连江水库有养鱼面积1.5万亩.库底淤泥较厚,有机质丰富。1988年调查,有水生植物28种,分属18科20属。以断面法测定,全库年总生物量(湿重)17317.9t,三个湖区都以沉水植物占绝对优势。近几年,水库草食性鱼年实际产量约2.5万 kg,为水库鱼产力的50%。合理利用水生植物资源的措施是:增加团头鲂、三角鲂等种类;增殖长春鳊资源;利用水生植物丰富的库汊、库湾进行围、拦养草食性鱼类。
The Three Lakes Lianjiang Reservoir fish culture area of 15000 acres.Carbon silts thick, rich organic matter. Survey in 1988, there are 28 species of aquatic plants, belonging to 18 families and 20 genera. Measured by the cross section method, the total annual biomass (wet weight) of the whole reservoir was 17317.9t, and submerged macrophytes dominated the three lake areas. In recent years, the annual actual output of herbivorous fish in reservoirs is about 25,000 kg, which is 50% of that of reservoir fish. Rational use of aquatic plant resources measures are: to increase the group ditch, triangular plover and other species; proliferation of spring chandelier resources; the use of aquatic plants rich library 汊, library Bay for the periphery, stop feeding herbivorous fish.
