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 and low weight gain rate
[0007] Although there are some special powdered feeds for Japanese eels on the market, due to the influence of feed processing technology, their fat content is low, which does not meet the nutritional needs of Japanese eels
Moreover, the nutritional level of ordinary extruded feed and powder on the market does not match the nutritional needs of Japanese eels, and there is a lack of an extruded feed designed for the nutritional needs of Japanese eels

Abstract

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

Description

technical field [0001] The invention relates to the field of aquatic fish feed, in particular to a special extruded feed for Japanese eels, a preparation method and application thereof. Background technique [0002] Japanese eel is one of the main varieties of artificially cultured eel. It has the basic characteristics of fish and looks like a snake. The optimum growth water temperature is 25-30°C. [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 eels is determined by the environment an...
