Problems solved by technology

This patent provides a raw fish compound feed with low feed coefficient, balanced nutrition, strong food-attraction and good stability in water, but the amount of fish meal is as high as 37-48%. Fish meal is a raw material with high nitrogen and phosphorus, and the feed also adds 0.8-1.2% calcium dihydrogen phosphate is added, although this feed formula can quickly promote the growth of raw fish, but the discharge of N and P is high, which is not good for the environmental protection of water bodies

Description

【Technical field】 [0001] The invention relates to a raw fish feed and a preparation method thereof, in particular to an environment-friendly raw fish puffed feed with low nitrogen and phosphorus discharge and a preparation method thereof, belonging to the field of aquatic feed. 【Background technique】 [0002] Raw fish, scientific name hybrid snakehead, belongs to the distant hybrid offspring of black snakehead and spotted snakehead. It is one of the important economic fish breeding species in my country. It is widely loved by people because of its delicious meat and rich nutrition. At present, some manufacturers one-sidedly pursue the economic benefits of raw fish farming and ignore the protection of the water environment. The amount of fish meal in raw fish compound feed on the market reaches 30% to 50%, and fish meal contains 50% to 72% of crude protein and 1.6% to 4.2% of phosphorus. It is a high nitrogen (N) phosphorus (P) raw material, feed formula Unreasonable structu...
