池塘养鱼不仅要提高单产,更重要的是应与经济效益联系起来。因此,养鱼户必须掌握当地市场鱼货价格、销路等规律与信息,合理调整养鱼品种,以取得最佳的经济效益。从淡水鱼市场价格看,由于北方地区特别偏爱鲤鱼,全年每公斤鲤鱼价为5—12元,而鲢、鳙鱼仅2—4元,草鱼的价格处在两者之间。这几种鱼虽差价悬殊,鲤鱼却又很畅销,鲢、鳙鱼又相对滞销。这是因为群众生活水平高了,对鱼的品质要求也随之提高。从这一点看,多养鲤、草鱼应该是有利可图。
Pond fish culture not only to improve yields, more importantly, should be linked with the economic benefits. Therefore, fish farmers must master the local market fish prices, sales and other laws and information, a reasonable adjustment of fish species, in order to obtain the best economic benefits. From the price of freshwater fish market, carp price per kg of carp is 5-12 yuan for the whole year due to the special preference of carp in the northern area. However, the price of silver carp and bighead carp is only 2-4 yuan, and the price of grass carp is between the two. Although these types of fish disparity, carp is very popular, silver carp, mackerel and relatively unsalable. This is because the living standards of the masses are high, and the quality requirements of the fish also increase. From this point of view, more carp, grass carp should be profitable.
