Mullet and crucian carp mixed culture puffed feed and preparation method thereof

Abstract

The invention relates to a mullet and crucian carp mixed culture puffed feed and a preparation method thereof, and belongs to the technical field of aquatic feeds. The mullet and crucian carp mixed culture puffed feed is prepared by the steps of crushing fish meal, soya bean meal, rapeseed meal, peanut meal, DDGS (Distillers Dried Grains with Soluble), peas, bean curd residues, cottonseed meal, wheat, cassava, corns and rice bran, and then agitating and uniformly mixing with soya-bean oil, monocalcium phosphate, an anthraquinone extract, glycine betaine, allicin, table salt and a fish premix to obtain a mixture; agitating, uniformly mixing and crushing the mixture by an ultrafine grinder to obtain a mixed material; transferring the mixed material into a regulating device and introducing vapor for regulating; after the regulation, conveying the mixed material into an extruding and puffing granulation machine to prepare pellet feeds; drying the puffed pellet feeds, cooling and packaging. The puffed feed has balanced and abundant nutrition and the nutritional requirements of mullets and crucian carps can be met at the same time; the puffed feed is used for the mixed culture of the mullets and the crucian carps and has the good stability in water; the puffed feed floats on the water surface and the ingestion efficiency is improved; the food coefficient is reduced and the cultivation cost is reduced; the pollution to a water environment is reduced.

Description

technical field [0001] The invention relates to a barracuda and heterogeneous gibel crucian carp polyculture extruded feed and a preparation method thereof, belonging to the technical field of aquatic feed. Background technique [0002] Barracuda is a wide-salt and wide-temperature omnivorous fish. Its protein requirement is low, its growth rate is fast, and its meat is fresh and tender, delicious, and has strong disease resistance. It is widely cultivated in coastal areas of our country. Under natural conditions, barracudas often scrape benthic diatoms and organic debris deposited on the surface of the bottom mud, and also eat some filamentous algae, copepods, polychaetes, molluscs and small shrimps. In terms of conditions, it also likes to eat rice bran, bean cake powder, peanut cake powder, dried daphnia and artificial bait. Allogenetic gibel carp is an important freshwater aquaculture species in my country. However, in recent years, frequent diseases have occurred in aq...
