[0005] The technical problem to be solved by the present invention is to overcome the defects and deficiencies of the above-mentioned prior art, and provide a special open feed suitable for the habits of large yellow croakers, which can solve the problems of dull color, poor meat quality and taste, high-density breeding, frequent diseases, Problems such as poor body shape have broken through the shortcomings of traditional seedling raising, reduced labor, added animal protein and unsaturated fatty acids, and optimized the entire formula to increase digestibility and nutrition. The low-flour formula reduces sugarmetabolism. At the same time, it ensures the water resistance of pellet feed, significantly and effectively promotes the growth of larvae and juvenile fish, and has strong food attractant, which has the advantages of enhancing opening rate, promoting growth and improving survival rate

Abstract
The invention discloses starter feed of larimichthys crocea and a preparation method of the starter feed. The feed is prepared from the following ingredients by mass percentage: 20-60% of white fish meal, 10-30% of chicken powder, 3-10% of egg powder, 3-10% of beer yeast, 8-30% of wet artemia, 5-15% of spirulina, 2-5% of flour, 1-5% of fish oil, 1-3% of phospholipid, 1-3% of betaine, 1-2% of vitamin mixture, 2-4% of mineral element mixture, 1-3% of EPA (eicosapentaenoic acid), 1-5% of DHA (docosahexaenoic acid), 1-5% of microbial preparation and 1-2% of phagostimulant. The starter feed of thelarimichthys crocea can solve the problems of dim color, poor meat and taste, frequent diseases, poor figure and the like of the larimichthys crocea, achieves high density cultivation, breaks throughdefects of the traditional fry breeding, reduces manpower, improves digestible absorbency and nutrition, and reduces sugarmetabolism burden; at the same time, the water resistance of pellet feed is ensured; the young fish growth can be promoted significantly and effectively; and the starter feed is strong in feed attraction and has the advantages of increasing a diet rate, promoting the growth and increasing a survival rate.
Description
technical field [0001] The invention belongs to the technical field of aquaculture. More specifically, it relates to a large yellow croaker opening feed and a preparation method thereof. Background technique [0002] Large yellow croaker is one of the traditional "four seafood" (large yellow croaker, small yellow croaker, hairtail, squid), and is the main economic fish in my country's coastal waters. [0003] Large yellow croaker has been artificially bred. In 2016, there were nearly 2 billion large yellow croaker seedlings. The fishing moratorium period increased, the price of chilled food increased, and there were many diseases in the cultivation of biological bait, which was greatly affected by external factors. At the same time, the supply of biological bait was insufficient, the quality was unstable, and the nutrition was not good. balanced, resulting in a low survival rate. Affected by biological characteristics and breeding methods, large yellow croaker and other fi...
