Method for breeding finless eel in pond

Abstract

The invention provides a method for breeding finless eel in pond in order to solve the problem that the fertility rate, the hatchability and the survival rate of the finless eel are low during the fully artificial propagation process at present, and therefore, the scale breeding requirements can not be satisfied. The method comprises the following steps: simulating a natural breeding environment of the finless eel in the pond, accelerating maturity of the finless eel by an artificial method, enabling a female finless eel and a male finless eel to voluntarily mate and propagate in the pond, andsufficiently utilizing a foam nest required in natural propagation to incubate, thereby greatly increasing the fertility rate, the hatchability and the survival rate of the finless eel, and thereforethe problem of scale breeding of finless eel fries.

Description

technical field

[0001] The invention belongs to the technical field of aquaculture, and in particular relates to a method for large-scale artificial propagation of eel seedlings by using ponds. Background technique

[0002] Rice field eel is a special aquaculture species with high protein, low fat and therapeutic effect. With the gradual reduction of wild eel resources and the increasingly prominent contradiction between supply and demand in the market, artificial breeding of eels has become an inevitable trend in the development of special aquatic industries. However, at present, the seedlings of artificially cultured rice field eels mainly come from wild catches. Due to the increasing scarcity of natural rice field eel seed resources and the immature artificial propagation technology of rice field eels, the development of rice field eel industry is seriously restricted. At present, the method of artificial breeding of rice field eel mainly adopts the methods of injecting ...
