Expanded pelleted feed of grown eel fishes without pollution

Abstract

The invention discloses a nuisance-free bulked granulated compound feed for adult eels, which comprises steam heated fish meal 45-55%, flour 18-25%, soybean waste 5-15%, bulked soybean 1-10%, fish oil 2-6%, brewer's yeast powder 2-6%, minerals 1-3%, choline chloride 0.3-1%, and vitamins for eels 0.2%. The feed has a higher conversion rate.

Description

technical field [0001] The invention relates to the field of fish feed, in particular to the field of eel feed. Background technique [0002] Eel, Anguilla japonica, commonly known as eel, is an important marine fish. In the traditional eel breeding process, most of them are fed with powdered feed after being stirred into agglomerates. This feeding method has the disadvantage of polluting the water quality due to the dissolution of the feed. In recent years, the culture of European eel has emerged, requiring fresh water quality and relatively stable breeding conditions, otherwise it is very easy to get sick. Especially since 1996, because the price of finished eels has fallen sharply, farmers are in urgent need of a high-quality and low-cost eel feed that can reduce water pollution. [0003] Due to the advantages of low production cost, high digestion utilization rate, low aquaculture cost, less pollution to aquaculture water, and wide range of raw material sources, extrud...

AI Technical Summary

Problems solved by technology

However, compared with the traditional powdered feed, the quality of eel extruded pellet feed is slightly worse, such as eel feeding instability, poor body color (brown), etc., which affects the commodity value

Therefore, the use of eel extruded pellet feed to breed eels is not yet popular, especially in my country. The promotion of eels has been affected. Guangdong has re-used powdered feeds within two months of eel cultivation, while Fujian Province still uses powdered feeds. Eel feed mainly feeds eels, and no extruded pellet feed is used
