Black carp feed

Abstract

The invention provides a black carp feed. The feed is prepared from the following components in percentage by weight: 10-20 percent of pork lung, 10-20 percent of rapeseed meal, 10-15 percent of soya bean meal, 8-15 percent of rice bran, 2-4 percent of grease, 15-20 percent of fish powder, 6-10 percent of kelp, 0.1-0.5 percent of edible salt, 3-15 percent of wheat bran, 0.1-0.3 percent of choline chloride and 0.7-1.8 percent of premix. The black carp feed is prepared by mixing and blending a plurality of plant components, the mixture is rich in protein, fat, vitamins and minerals and facilitates absorption of black carp and growth and development of black carp, and the components adopted in the nutritional fish feed are common products and low in production cost.

Description

technical field [0001] The invention relates to a feed, in particular to a herring feed. Background technique [0002] Herring is one of the four major fishes in my country. It has always been a favorite delicacy of consumers, and it is also a first-class delicacy and gift for festivals, weddings and ceremonies. At present, there are several major problems in the breeding technology of herring: First, in the environment of still water ponds in most of my country's aquaculture industry, high-density aquaculture causes a large amount of aquatic animal excrement, residual bait, disinfectant, etc. A large amount of harmful substances are released, which increases the density of aquaculture, deteriorates the water environment, and aquaculture diseases are also increasing. Many diseases have seriously threatened the efficiency of aquaculture. The loss of feed in water and the accumulation of excreta have become the main sources of pollution of water bodies, leading to deterioratio...

Problems solved by technology

At present, there are several major problems in the breeding technology of herring: First, in the environment of still water ponds in most of my country's aquaculture industry, high-density aquaculture causes a large amount of aquatic animal excrement, residual bait, disinfectant, etc. A large amount of harmful substances are released, which increases the density of aquaculture, degrades the water environment, and aggravates aquaculture diseases. Many diseases have seriously threatened the efficiency of aquaculture.

However, the loss of feed in water and the accumulation of excreta have become the main pollution sources of water bodies, resulting in deterioration of water quality, large-scale reproduction of pathogens, decreased survival rate, increased dosage of medicines, frequent water changes, and increased breeding costs.
