如何保持池塘渔业的高速发展,增强发展后劲。是当前渔业发展的中心问题之一。笔者根据我省情况,就养鱼池塘的清淤问题,谈点浅见。旨在引起各级领导的高度重视,推动池塘渔业的持续稳步发展。一、池塘渔业在渔业中有举足轻重的地位 1991年全省水产品总量为56.30万t,比1978年的11.87万t增长了3.74倍。其中:池塘产量达到42.20万t,比1978年的7.19万t增长了4.87倍。1991年比1978年水产品产量绝对增加数为44.43万吨,其中池塘产量绝对增加数为35.01万t,占全省水产品产量绝对增加数的78.80％。 1978年至1991年年平均放养面积为469.65万亩,其中池塘养殖面积为234.67万亩,占总放养水面的49.77％;年平均养殖产量为29.01万t,其中池塘产量为23.44万t,占养殖总产的80.80％
How to maintain the rapid development of pond fishery and enhance the development potential. It is one of the central issues in the current development of fisheries. According to the author’s situation in our province, the fish pond dredging problems, talk a little advice. Aiming at arousing the great attention of leaders at all levels and promoting the sustainable and steady development of the pond fishery. First, the pond fishery has a pivotal position in the fishery In 1991, the total amount of aquatic products in the province was 563,000 tons, an increase of 3.74 times that of 118,700 tons in 1978. Of which: the pond production reached 4220000 t, compared with 719000 t in 1978 increased by 4.87 times. The absolute increase in the output of aquatic products from 1991 to 1978 was 444,300 tons, of which the absolute increase in pond production was 350,100 tons, accounting for 78.80% of the absolute increase in the province’s aquatic product output. From 1978 to 1991, the average annual stocking area was 4,696,500 mu, of which 2,346,700 mu was pond aquaculture, accounting for 49.77% of the total stocking water surface; the annual average aquaculture production was 290,100 t, of which the pond production was 234,400 t, The total output of 80.80%
