Ecological type compound feed for juvenile Centropristis striata

Abstract

The invention discloses centropristis striata linnaeus young fish ecotype mixed feed, which is characterized in that the mixed feed is prepared from the following components in weight percentage: 52.0 to 62.5 percent of fish meal, 1.0 to 6.0 percent of casein, 6.0 to 11.0 percent of wheat gluten, 13.0 to 25.0 percent of alfa-starch, 0 to 3.0 percent of fish oil, 0.5 to 7.0 percent of soybean oil,0 to 17.0 percent of cellulose powder, 0. to 0.9 percent of mixing powder of a plurality of amino acids, 0.5 to 1.0 percent of composite vitamins, 0.8 to 1.2 percent of composite mineral salt, 0.01 to 0.05 percent of zymin, 0.1 to 0.6 percent of small peptide and 0.05 to 0.3 percent of compound traditional Chinese herbal preparation. Tests show that the centropristis striata linnaeus young fish fed by the mixed feed has the advantages of high feed intake, obvious food calling and high growth rate; and the weight is averagely increased by 24.50 to 69.62 percent, the survival rate is up to between 90.0 and 100 percent which is 85.0 percent higher than that of the comparative group, feed coefficient is up to between 1.20 and 1.84, and disease resistant capability is improved.

Description

Technical field: [0001] The invention relates to a compound feed for fish, in particular to a compound feed for juvenile American black grouper [Centropristis Striata]. Background technique: [0002] Since the reform and opening up, my country's agricultural production level has been rapidly improved, the development has been strengthened, and the momentum is good. It provides people with rich and cheap animal food, especially in the process of developing blue agriculture, and the aquaculture industry has achieved unprecedented development. For aquaculture, due to the lag and weakness of research on fish nutrition and physiology, it is difficult to provide accurate nutritional requirements for fish animals, and it is impossible to produce suitable compound feed for fish, which makes aquaculture even more difficult. Better and faster development constitutes a "bottleneck". At the same time, with the development of economy and society and the improvement of people's living st...
