Problems solved by technology

At present, there are few researches on the special opening feed for European seabass. Most of them use natural baits such as rotifers as the opening 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 are not considered, and the effect of attracting food is poor, which cannot ideally promote the growth and development of fry.

Abstract

The invention discloses dicentrarchus labrax starter feed and a preparation method thereof. The starter feed is prepared from the following components in percentage by mass: 20-40 percent of fish meal, 10-30 percent of chicken meal, 3-10 percent of shrimp shell meal, 3-10 percent of yeast, 10-30 percent of blood worms, 5-15 percent of squid meal, 5-15 percent of copepods, 15-30 percent of flour, 1-5 percent of soybean oil, 1-3 percent of phospholipids, 1-3 percent of glycine betaine, 1-2 percent of vitamin mixture, 2-4 percent of mineral mixture, 1-5 percent of EPA, 1-5 percent of a compound exogenous enzyme preparation, 1-5 percent of a microbial preparation and 1-2 percent of attractant. The feed is designed, researched and developed according to the rule of nutritional requirements of dicentrarchus labrax fries, has a grain size meeting the high requirement of dicentrarchus labrax grow seedlings, has strong attraction performance and strong digestability and absorbability, and can be used for remarkably reinforcing the starting rate and immune level, effectively promoting healthy growth of fries and remarkably increasing the survival rate of larvae.

Description

technical field [0001] The invention belongs to the technical field of aquaculture. More specifically, it relates to an open mouth feed for European seabass and a preparation method thereof. Background technique [0002] European perch is a kind of fish under the genus of perch. It can survive in both fresh water and salt water. It is one of the important economic fish in Europe and the second largest cultured species in Europe except salmon. The market price of this fish is relatively high in Europe, but it is not yet available in the Chinese market, and there are only a small amount of breeding technology research reports. The fish has a high meat yield, no spines, delicious taste, high nutritional value, and has a high breeding prospect. [0003] Affected by biological characteristics and breeding methods, there are still large differences in nutritional requirements between European seabass and other fish. At the same time, because European seabass has different nutri...
