发展我市水库渔业,为人民提供更多的商品鱼——优质蛋白,从价值形态上说,是创造了财富。从生态学效率方面考虑,则是射入水中的太阳能转化为产品。我市水库养殖总面积为57.06万亩,占全市总水面的60％(不包括河流水面)。目前我市水库鱼产量还很低,发展潜力很大。从历史上看,解放前后,我市水产品主要来自海河水系的河流,以及遍布各区县的洼淀(即现今部份水库前身),水产品市场供应鱼类品种繁多,数量大。而当时池塘养鱼很少,产量微不足道,说明天然水域中的商品鱼曾占绝对地位。现在随着环境条件的改变和工农业生产的发展,使得这些水库生产的商品鱼在整个淡水鱼总产量中所占的比重减小,年产和单产较低,单产最高的塘沽区黄港二库1981年平均亩产15公斤,单产最低的是静海县团泊水库1979—198(?)年平均亩产1.05公斤。我市两个大型水库鱼单产情况是:于桥水库1974—1980年平均单产为8.15公斤/亩,北大港水库1966—1980年平均单产为3.6公斤/亩。由于水库、洼淀主要依靠天然饵料,如管理得当,会发挥更大作用。
Development of our city reservoir fisheries, to provide people with more fish products - high-quality protein, from the value of morphology, is to create wealth. From the ecological efficiency point of view, it is into the water of solar energy into products. The total area of reservoir aquaculture in our city is 57.06 mu, accounting for 60% of the total surface water of the city (excluding river water surface). At present, the production of reservoir fish in our city is still very low with great potential for development. Historically, before and after the liberation, the aquatic products in our city mainly came from the rivers of the Haihe River system and from the depressions (that is, predecessors of some reservoirs) of various districts and counties. There are a large variety and large quantities of fish in the aquatic products market. At that time, very few fish ponds, production is negligible, indicating that the natural waters of fish had an absolute position. Now with the change of environmental conditions and the development of industrial and agricultural production, the production of commercial fish in these reservoirs has decreased in the proportion of the total output of freshwater fish. The annual output and yield per head are lower with the highest yield of Huanggang II Library in 1981 an average of 15 kilograms per mu, the lowest yield is static sea Mission Park Reservoir 1979-198 (?) Annual average yield 1.05 kilograms. The yields of two large-scale reservoir fish in the city are as follows: The average yield of Yuqiao Reservoir in 1974-1980 is 8.15 kg / mu, and the average yield of Beidagang Reservoir in 1966-1980 is 3.6 kg / mu. Due to the reservoir, Depression mainly rely on natural food, if properly managed, will play a greater role.
