Chinese carp spawn incubation equipment

Abstract

The invention discloses Chinese carp spawn incubation equipment, which is characterized by comprising a cylindrical tank body which is built on the ground and has an opening facing upwards and a spawn access pit which is connected with an opening on the bottom part of the wall face of the tank body and is lower than the bottom surface of the tank body, wherein at least three water filling openings are distributed and embedded in an annular form in the wall face of the tank body; the water outlet directions of the water filling openings are opposite to the tangential directions of the tank body; the water filling openings are connected to a discharge hole of a water pump by the same pipe; a cylinder which is lower than the outer edge of the tank body and higher than any water filling opening is arranged in the center of the tank body; the a water discharge hole which runs through the bottom surface of the tank body is formed in the center of the cylinder; and the inside wall face and bottom surface of the tank body and the outside surface of the cylinder have smooth structures. When the technical scheme of the invention is used, the natural environment of the water flow in Yangtze River can be simulated and created, so the spawn incubation efficiency is improved greatly. In addition, as the inside wall face and bottom surface of the tank body and the outside surface of the cylinder have smooth structures, the accumulation of the spawn at edges or corners is prevented effectively and the spawn is well protected from being damaged by accidental impact.

Description

technical field

[0001] The invention relates to an agricultural breeding equipment, in particular to an equipment for artificial hatching of fish eggs in the self-production breeding process of freshwater fish, and belongs to the technical field of fish farming in agriculture. Background technique

[0002] The four major fish refer to artificially raised herring, grass carp, silver carp, and bighead carp. It is a high-yielding fish species selected for polyculture in pond fish farming in China for more than 1,000 years. The four major family fishes all belong to Cyprinidae, Cyprinidae. Due to the rapid growth and strong disease resistance of these four types of fish, they are suitable as fish for public consumption. Moreover, the ages of the growth inflection points of the four major domestic fishes are all 2-3 years older than their sexual maturity ages, and they will continue to grow after sexual maturity.

[0003] From the perspective of fish farming technology, in add...
