Problems solved by technology

At present, there is little research on the special feed for sweet-scented osmanthus fish, and most of them use natural bait as the feed, which has the disadvantages of high cost, easy pollution of water quality, unstable quality, and easy introduction of pathogens such as parasites, bacteria and viruses.
Moreover, factors such as opening rules, nutritional requirements and feeding preferences of different fry were not considered.

Abstract

The invention discloses starter feed for mandarin fish and a preparation method thereof. The starter feed is made from, by weight, 20-60% of white fish meal, 10-30% of chicken meal, 3-10% of egg meal,3-10% of beer yeast, 10-30% of wet brine shrimp, 10-30% of fresh shrimp, 15-30% of flour, 1-5% of fish oil, 1-3% of phospholipids, 1-3% of betaine, 1-2% of vitamin mixture, 2-4% of mineral mixture, 2-6% of EPA (eicosapentaenoic acid), 1-5% of DHA (docosahexaenoic acid), 1-5% of a microbial preparation, and 1-2% of a food attractant. The starter feed herein is developed and researched according tonutrient needs and feeding characteristics of the mandarin fish, and the content of animal proteins is increased; the whole formulation is optimized, the particle size of the starter feed may reach dozens and even hundreds of micrometers, the requirements of different specifications of young fishes for particle size palatability can be met, digestibility, absorbability and attractiveness of the starter feed are effectively improved, starting rate is significantly increased, and fry survival rate is effectively increased.
