Problems solved by technology
[0003] 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 deteriorates the water quality of aquaculture; secondly, with the increase of aquaculture density, the water environment deteriorates, and aquaculture diseases are also increasing. 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.

Abstract
The invention discloses a feed for fish culturing, and particularly relates to a formula and production process of a black carp feed. The invention aims at providing the formula and production process of the black carp feed which has the advantages of good quality and little water pollution. The formula of the black carp feed comprises the following materials in percentage by weight: 26%-30% of fish meal, 4%-6% of shrimp meal, 18%-22% of soya bean meal, 7%-10% of peanut meal, 8%-12% of rapeseed meal, 20%-25% of high-gluten flour, 1%-2% of calcium biphosphate, 0.1%-0.3% of salt and 0.1%-0.5% of choline chloride. The obtained black carp feed has the advantages of good stability in water and high digestion ratio and utilization ratio of fishes on puffed feeds and can reduce a great amount of phosphorus and nitrogen emission every year by adopting a puffing technology and play a significant role in improving water quality and increasing the benefits of farmers.
Description
technical field [0001] The invention relates to a feed used for fish farming, in particular to a formula and a production process of 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. [0003] 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 deteriorates the water quality environment of aquaculture; secondly, with the increase of aquaculture density, the water body environment deteriorates, and the aquaculture diseases are also increasing day by day. Many diseases have seriously threatened the aquacu...
