Composite premix feed for freshwater fishes

Abstract

The invention provides a composite premix feed for freshwater fishes. According to the composite premix feed disclosed by the invention, the composite premix feed and a same large formula are in concerted application for being applied in actual production of a fish pond, and in an application process, the formula of the composite premix feed for the freshwater fishes is adjusted repeatedly, and current product quality and application effects are stable, so that the problems that the feed cost for crucian carps is high, the growth rate is not high, the bait coefficients are high, and the investment return rate is low are solved. The composite premix feed disclosed by the invention does not contain additives and medicines, which are not permitted to use in China, and the composite premix feed is guaranteed to conform to feed hygienic standards. Astragalus polysaccharide, bile acid, high-stability VC, VE, inositol and the like are added, so that the immunity and the stress resistance of fish bodies are improved, the constitutions are strong, the vitality is high, the death rate is low, and the freshwater fishes are safe to live through the winter, and are resistant to long-distance transport.

Description

technical field [0001] The invention belongs to the field of aquaculture and relates to a compound premixed feed for freshwater fish. Background technique [0002] "National crucian carp is based on Jiangsu, and Jiangsu crucian carp is based on Yancheng", which tells the proportion of Jiangsu crucian carp in national aquaculture. The aquaculture area in Jiangsu is 11 million mu, of which the freshwater aquaculture area is nearly 8 million mu. The freshwater aquaculture area in Yancheng is nearly 4 million mu. The main species of aquaculture are crucian carp and grass carp. [0003] The development of the breeding level of the whole heterogeneous gibel carp can be divided into three stages: from 2001 to 2004, the heterogeneous gibel carp grew from 0.1 catties / tail to 1 catties / tail, and the feed coefficient was 2.0, but the feed price was low. The breeding cost is low, and the farmers have a net profit of 300-1000 yuan / mu; from 2005 to 2009, the heterogeneous gibel crucian c...
