我省有小型水库11757处,养殖面积63万多亩,其中小一型1772处,32万多亩,小二型9985处,31万多亩。这些小型水库一般分布在山丘区,为发展山区渔业,解决山区人民吃鱼难提供了良好的条件。要开发利用这部分水域,首先必须分析它的渔业优势和潜力,再采取措施,使优势和潜力得以发挥。山区小型水库发展养鱼,有它独特的优势。一,水面大小适合精养半精养。小一型水库一般养殖面积200亩左右,小二型水库30亩左右,水深一般在6—7米左右,加上权属一乡一村,社会问题少,又不与农争地,这样便于经营,便于管理。二,水体清新,溶氧充足,水温昼夜变化小。外源性营养物质丰富。这些生态方面的优势是池塘无法相比的。三,鱼种来源、防逃、捕捞等问题易解决。这对于大中型水库来说是“老大难”问题。由于水面小,所需鱼种池不多,一般
There are 11,757 small reservoirs in our province with a breeding area of 630,000 mu, of which 1,772 are small ones, 32,000 mu are small ones, 9985 are small ones and 310,000 mu are small ones. These small reservoirs are generally distributed in hill areas, which provide good conditions for developing mountain fisheries and solving the problems of mountainous people eating fish. To develop and utilize this part of the waters, we must first analyze the advantages and potential of its fisheries and take measures to make the advantages and potentials come into play. The development of fish farming in small reservoirs has its unique advantages. First, the size of the water for intensive semi-intensive. Small reservoirs general breeding area of about 200 acres, about 30 acres of small reservoirs, water depth is generally about 6-7 meters, plus ownership of a rural village, less social problems, not with the agricultural land, so easy Management, easy to manage. Second, fresh water, adequate oxygen, water temperature changes day and night small. Exogenous nutrients rich. These ecological advantages are unmatched by ponds. Third, the source of fish species, anti-flight, fishing and other issues easily solved. This is a big deal for large and medium-sized reservoirs. Due to the small water surface, small fish ponds are required, in general
