Problems solved by technology

[0005] (1) Powder breeding: there are three types of eels that are prone to enteritis, (also known as eel essence, left seedlings or eel tails, mainly refer to some eels that grow slowly or are small and difficult to grow, and generally weigh only a few grams. ) problems such as large quantity, low feed absorption rate, large water pollution, and high feed price;
[0006] (2) Extruded feed farming: there are problems of low feed efficiency, low weight gain rate, and high feed price
[0007] At present, there is no feed specially designed for the nutritional needs of American eels on the market, and the nutritional level of common extruded materials and powders on the market does not meet the nutritional needs of American eels, thus affecting the growth performance of American eels and reducing the Benefits of farming

Abstract

The invention discloses a puffed feed for American eels. The puffed feed comprises the following components: fish meal, chicken meal, mixed vegetable protein, fermented soybean meal, hydrolyzed feather meal, glutamic acid residues, monocalcium phosphate, high-gluten flour, mixed vegetable oil, choline chloride, bile acid, a vitamin mixture, a mineral substance mixture, methionine and lysine. The invention also discloses an application of the American eel expanded feed in American eel culture. The feed disclosed by the invention has the characteristics of low cost, high feed efficiency and thelike, and can improve the growth performance of the American eel, improve the breeding weight gain rate and survival rate of the American eel, reduce the morbidity of enteritis, promote fat and protein metabolism, guarantee the liver and gallbladder health of the American eel and improve the breeding benefit.

Description

technical field [0001] The invention relates to the field of aquatic fish feed, in particular to an American eel extruded feed and a preparation method and application thereof. Background technique [0002] American eel is one of the main species of artificially cultured eel. It has the basic characteristics of fish, its appearance is like a snake, the number of vertebrae is 103-111, and the optimum growth water temperature is 22-28 ℃. [0003] Eels belong to the ray-finned fish class, eel order, eel suborder, and eel family. They are downriver migratory fish, that is, eels grow in land rivers and migrate to the spawning grounds in the ocean after maturity. Life history can be divided into egg stage (spawning in the sea), willow leaf eel (drifting with ocean currents, as thin as a willow leaf), glass eel (transparent glass eel seedlings), eel thread (melanin begins to appear, the main source of seedlings), Yellow eel (yellow belly), silver eel (silver belly). The sex of ee...
