Fishes oosperm hatcher with all-directional hydrologic cycle

Abstract

The invention discloses an all-wave water cycle fish germ cell hatchibator, which relates to a fish germ cell hatching device which is essentially composed of a pelagic ring (1), a sieve cloth canister (2), a pressure water tray (3), a base basin (4) and a pressure pipe (5); the pelagic ring (1), the sieve cloth canister (2) and the base basin (4) are connected from up to down in sequence; in thebase basin (4), the upper part thereof is provided with the pressure water tray (3) and is fixed by a bolt (7); the bottom of the base basin is provided with the pressure pipe (4) and is fixed by a fastening piece (6). The all-wave water cycle fish germ cell hatchibator has simple structure, light weight, and convenient collection, remotion and carrying; the water cycle has no dead angle, and thehatchability of the germ cell is improved; the area for water passing through is increased, and an egg membrane cannot stuck on the sieve cloth for filter water when a fish berry deciduates, therefore, the sieve cloth does not need to be washed and brushed, the use is convenient, and the cost and the physical force are saved. The all-wave water cycle fish germ cell hatchibator has high cost performance, thereby being applicable to the effective hatch of the fish germ cell.

Description

technical field [0001] The invention relates to a fish fertilized egg hatching device, in particular to a fish fertilized egg hatcher with all-round water circulation. Background technique [0002] Aquaculture is an important way for human beings to use water resources to develop the economy, improve the diet structure, and improve people's living standards; the promotion and utilization of aquaculture technology is the responsibility and obligation of aquaculture science and technology workers to serve the society and benefit mankind. [0003] In aquaculture technology, the hatching of fish fertilized eggs is one of the important links, and it is very important to improve the quality of fish fertilized eggs hatched. Fertilized eggs can be hatched in different containers, either in static water in cages, or in running water in hatching tanks, hatching tanks, and nursery ponds. [0004] The existing hatching tanks are mostly made of ceramic tanks, such as figure 1 , 2 It i...

Problems solved by technology

However, there are dead angles in the water cycle, which cause fish eggs to adhere to a large range of tank walls and affect the success rate of hatching; and because of the small water passing area, the egg membranes are easy to adhere to the water filter mesh when the fish eggs are removed. Blocking the mesh, making fish eggs or fry overflow out of the tank, causing huge losses
