Method for promoting natural egg reproduction of common carp and crucian carp

Abstract

The invention discloses a method for promoting natural egg reproduction of common carp and crucian carp. The method comprises the steps of making spawning nests with a natural herbaceous plant material for eggs of common carp and crucian carp to be adhered to; placing the spawning nests into a water area at the proper time; after the spawning nests are placed well, installing underwater lights in water below the spawning nests at intervals of 50 meters, wherein the underwater lights are used for inducing common carp and crucian carp to enter the spawning nests to lay eggs for reproduction; and every 3-5 days, spraying a proper amount of salt solution or potassium permanganate solution onto the surfaces of the spawning nests, so that the eggs can be adhered more firmly and embryonic development of healthy fertilized eggs can be protected. With the adoption of the method, common carp and crucian carp resources in lakes and reservoirs can be proliferated effectively. The spawning nests and a corresponding technique provided by the invention are simple in technology and low in cost, and no advanced facility instruments are required.

Description

technical field [0001] The invention relates to the technical field of fish reproduction and resource multiplication, in particular to a method for promoting natural spawning and reproduction of carp and crucian carp. Background technique [0002] Carp (Cyprinus carpio Linnaeus) and crucian carp (Carassius auratus Linnaeus) are widely distributed in major rivers, lakes, reservoirs and ponds across the country, and are important economic fish in my country. Carp and crucian carp have the habit of laying sticky eggs with philodendron. During the breeding season every spring, carp and crucian carp can naturally spawn and reproduce in natural water bodies rich in aquatic plants. However, no matter what kind of water bodies such as rivers, lakes, reservoirs, etc., the lack of aquatic plants will inevitably seriously affect the natural spawning and reproduction of carp and crucian carp, which will eventually lead to a continuous decline in the natural resources of carp and crucian...

AI Technical Summary

Problems solved by technology

In recent years, in order to increase fish resources, although "floating artificial fish nests", "fixed artificial fish nests" and the construction of "gravel artificial spawning grounds" have emerged to simulate fish nests and spawning grounds, However, in inland lakes, reservoirs and other large water surfaces that lack aquatic plants, carp and crucian carp resources are multiplied. How to choose cheap, easy-to-obtain, and large-scale artificial fish nest materials, choose suitable artificial fish nest breeding areas and scientifically set fish nest scales. There is still a lack of technical methods to accurately grasp the spawning timing of carp and crucian carp, timely set up artificial fish nests, and protect the setting places of artificial fish nests from damage and influence.
