Problems solved by technology

[0007] 3. The energy provided by the above-mentioned patents for farmed fish is mainly through soybean oil and vegetable oil, but the content of unsaturated fatty acids contained in soybean oil and vegetable oil is relatively low, and the energy supply is relatively weak
[0008] 4. The traditional compound feed pollutes the aquaculture water more, and the digestion and absorption of the aquaculture fish is poor
[0009] In short, although the above invention patents have a certain effect on the color retention of yellow catfish, they have certain deficiencies in the growth performance of the cultured fish and the pollution of the cultured water. Higher and higher cost of farming

Abstract

The invention discloses a swelling granular mixed feed for postlarva of pelteobagrus fulvidraco, relating to the field of pelteobagrus fulvidraco feed. The feed is suitable for feeding the pelteobagrus fulvidraco in postlarva stage (namely the pelteobagrus fulvidraco in the postlarva stage with the weight of 0.2-2g); the feed is a mixture prepared by all raw materials according to the processing method of expanded granular feeds; according to the weight percentage, the feed comprises the following raw materials of: 50-55% of fish meal, 18.48-20.4% of flour, 1-2.5% of cottonseed meal, 11-15% of soybean meal, 1-2% of maize protamine, 2.5-3.5% of fish oil, 4-5.5% of beer yeast, 0.9-1.5% of mineral matters, 0.4-0.7% of choline chloride and 0.2% of multivitamin. Compared with normal mixed feed, the swelling granular mixed feed has the advantages of comprehensive nutrition, high livability, little pollution on culture water, greenness, and no public nuisance.

Description

technical field [0001] The invention relates to the field of fish feed, in particular to the field of puffed granule compound feed for juvenile yellow catfish. Background technique [0002] Pelteobagrus fulvidraco Rich belongs to Siluriformes, Crocodiles, and the genus Pelteobagrus fulvidraco, also known as Huangga, Huangguzi, Huanglatin, etc. Small freshwater bottom economic fish commonly found in lakes, reservoirs, ditches and other waters. [0003] Natural yellow catfish is a mild bottom carnivorous small fish with high edible value and certain medicinal value. In recent years, with the increase of people's demand for yellow catfish, wild yellow catfish can no longer meet the demand of the market, and people have begun to adopt the method of artificial feeding to raise yellow catfish. For the yellow catfish in the juvenile stage, starting from 5 days after it emerges from the membrane, it is generally cultured by feeding on zooplankton and artificially feeding with feed...
