Intensive fry breeding system of Pelteobagrus fulvidraco

Abstract

An intensive fry breeding system of Pelteobagrus fulvidraco includes a disease prevention and control region for fish body quarantine and sterilization of personnel, tools and water entering the system; a parent fish sorting region including at least one parent fish temporary culture pond for cleaning and specification sorting of parent fishes entering the system from outside; a parent fish spawning inducement region including at least one spawning inducement pond and at least one injection workbench for performing injection spawning inducement to parent fish; an artificial insemination region for completing artificial spawn collection, artificial insemination, artificial debonding and washing; a spawn hatching region including at least one set of fry hatching device for hatching spawn into fry; and a fry temporary culture region including at least one fry temporary culture pond for temporary culture and first-feeding, wherein the disease prevention and control region, the parent fish sorting region, the parent fish spawning inducement region, the artificial insemination region, the spawn hatching region and the fry temporary culture region are all arranged at the production site. The above functional regions are adjacent in sequence. The inventive system has novel facilities, industrialized and large-scale fry breeding and reduced fry propagation cost, and is small in land occupation and low in water consumption.

Description

technical field [0001] The invention relates to fish cultivation, in particular to an intensive fish fry breeding system for peliotus catfish. Background technique [0002] Pelteobagrus fulvidraco is an important economic food fish in my country, and its market demand is constantly increasing. At present, the supply of yellow catfish fry is in short supply. Although the production of yellow catfish fry has been carried out all over the country, the backward production technology restricts the production scale, resulting in low output and cannot meet the production needs. The traditional fish fry artificial breeding firstly controls the fish fry production process based on experience, but there is no quantitative standard for the important key control indicators in the production process, so the production cannot be standardized; Facilities such as hatching boards, palm bark, and earthen ponds for semi-artificial spawning will lead to uneven quality of fry, and the number of...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide an intensive fry breeding system for yellow catfish, which can solve the problem that the aging of the fry production facilities of yellow catfish in the above-mentioned prior art affects the quality of fry, and occupies a small area and saves water. Realize the industrialization and scale of fry production, and reduce the cost of fry breeding
