今年我区的网箱养鱼试验,由于着手比较晚,各项准备工作不充分,结果不算太好,但也有一定的收获。初步证明,网箱养鱼在鱼类饵料生物比较丰富的水域,即使在不投饵的情况下,可以认为是一种比较有前途的养殖方法。对水质比较清瘦的水域,如能保证饵料的供应,则对一些索食性鱼类(如草、鲤等)的养殖,也是非常有希望的。如遵化县般若院水库由于水质比较肥沃,成鱼网箱亩产10250斤的滦南大顾庄,水质亦比较肥沃,鱼种网箱折合亩产四点四六万尾,鱼种规格42—62尾/斤,鲢鳙鱼体长达四、五寸。玉田县河渠(水质较 This year my cage fish cage test, due to start relatively late, the preparatory work is not sufficient, the result is not too good, but there are some gains. Preliminary evidence shows that fish cage aquaculture in the relatively rich biological waters, even in the case of not feeding, can be considered a more promising breeding methods. For the relatively watery waters, if the supply of bait can be guaranteed, it is also very promising for the culture of some of the predatory fish (such as grass, carp, etc.). For example, Zunhua County as the hospital reservoir as a result of more water quality, fish cage per capita production of 10,250 kg of Luannan Zhu Gu Zhuang, water quality is more fertile, fish cage equivalent to 46,400 mu, fish species size 42-62 Tail / kg, silver carp and bighead carp as long as four or five inches.
