The special feed comprises raw materials in parts by weight as follows: 20-80 parts of fish meal, 30-80 parts of prawn powder, 15-35 parts of blood worm powder, 2-8 parts of cod-liver oil, 1-3 parts of palm oil, 1-4 parts of citrus oil, 10-30 parts of bone meal, 20-30 parts of sweet corn protein powder, 8-14 parts of corn germ meal, 2-10 parts of bean pulp, 10-30 parts of fermented bioprotein, 5-15 parts of black sesame powder, 8-14 parts of bloodworms, 0.5-3 parts of aloe powder, 0.5-3 parts of lotus leaf powder, 0.1-0.8 parts of cerium citrate, 1-3 parts of methionine, 1-3 parts of threonine, 0.01-0.07 parts of a complex enzyme, 0.01-0.09 parts of microelements, 1-3 parts of Chinese herbal medicines, 2-10 parts of an attractant and 0.5-1.5 parts of multivitamins. With the adoption of the special feed, even if under the condition of manual high-density culture, the fatality rate of the mandarin fish fries is very low, the feed is good in palatability and high in nutritional value, the ratio is reasonable, the cost is low, and fish is delicious.

Description

technical field [0001] The invention relates to the technical field of aquatic feed, in particular to a special feed for mandarin fish fry. Background technique [0002] Mandarin fish is a rare and precious freshwater fish. It has the characteristics of fast growth and high nutritional value, and is deeply loved by the people. It keeps rising and reaches 120 yuan per kilogram, but this kind of fish has a peculiar food habit. It feeds on live fish and shrimps all its life. Under normal circumstances, it absolutely refuses to eat dead bait or compound feed. This phenomenon is very rare among fish. Live bait is fed, and mandarin fish fry will feed on other species of fry when they come out of the film. The supply of live bait has become a restrictive factor for the rapid and large-scale development of aquaculture production. Especially when mandarin fish is in the rapid growth period, the demand for live bait The cost of input by fishermen is extremely high, and how to prepare...

The supply of live bait has become a restrictive factor for the rapid and large-scale development of aquaculture production. Especially when mandarin fish is in the rapid growth period, the demand for live bait The cost of input by fishermen is extremely high. How to prepare an artificial feed for mandarin fish has become a technical problem that needs to be solved urgently.
