目前我县水库的鱼种池大都条件较差(均属沙滩建池),有的虽经改造,仍漏肥漏水较严重,每年培育鱼种需要大量的有机肥料,这不仅增加了生产费用,也因有机肥肥源的限制,影响扩大鱼种生产和提高鱼种规格。现在大多数水库的鱼种池单产水平很低,培养不出足够的规格大、质量好的鱼种投放水库,严重地阻碍了水库渔业生产的迅速发展。为此,我
At present, most of the fish ponds in our county reservoir are in poor condition (all belong to the beach construction pond). Although some of them have been transformed, they still leak more serious water leakage and require a large amount of organic fertilizer to breed fish species each year. This not only increases the production cost, Due to the restriction of organic fertilizer sources, the expansion of fish species production and the improvement of fish species specifications are also affected. At present, most reservoirs have very low yields of fish species ponds and not enough large-sized and good-quality fish species to be put into reservoirs, which seriously hinders the rapid development of reservoir fishery production. For this, me
