Simple and high-efficiency circulating water hatching system

Abstract

The invention discloses a simple circulating water hatching system, comprising a circulating water treatment system and a compound hatcher, wherein the circulating water treatment system comprises a water tank, a circulating water pump and a water quality treatment device, the compound hatcher comprises a water pump, a support and a hatching barrel which is provided with a water inlet and a water outlet, the water inlet and the water outlet of the hatching barrel are provided with protective screens which can prevent roes from escaping, and the water pump is used for driving water flow to keep the roes in the hatching barrel in a floating state. The circulating water treatment system disclosed by the invention can filter impurities out of the circulating water, sterilize and disinfect the circulating water and adjust the temperature of the circulating water, thus the roes can be hatched in optimal circulating water environment and the hatchability is high; the roesin the compound hatcher are in a floating state, thus sticky roes can be directly hatched while the viscosity is not reduced and the hatching way is simple and convenient; meanwhile, multiple layers of water tanks can be placed on a stereoscopic rack of the hatching system vertically, thus large-scale hatching can be realized in a smaller space and the hatching efficiency is high.

Description

technical field [0001] The invention relates to a hatching system, in particular to a fish egg hatching system. Background technique [0002] The artificial hatching of fish generally adopts the method for hatching loop or hatching bucket at present. The hatching ring road is generally built outdoors, the site scale is relatively large, and the construction cost is relatively high. It is mainly used for artificial hatching of the four major fish fry; the hatching bucket is a funnel-shaped drum, which is erected by a support. The former has a large scale and is not suitable for small-scale hatching. The hatching conditions are difficult to control and are easily affected by the weather. It is easy to form a dead angle in the hatching circuit, causing the accumulation of fish eggs to die. The latter has a single structure and cannot perform the hatching function alone. Since there are no special supporting facilities, it is very inconvenient to use, and the hatching condition...
