Water cascading type fish egg incubator

Abstract

The invention discloses a movable water cascading type fish egg incubation device, which is composed by assembling a plurality of incubators, wherein the quantity of the incubators can be adjusted according to the incubation scale. Each incubator is formed by bonding glass and internally provided with a water transfer chamber, an incubation chamber and a water collecting tank, and a water cascading type circulation structure is adopted. The device favorably overcomes various defects of high water consumption, low incubation efficiency, and the like of the traditional incubation equipment, has the advantages of energy and water saving, wide application range, low purchase cost, convenient management, high incubation efficiency, and the like, can be used for the artificial incubation of various types of fish eggs, and is suitable to fish fry production units or aquatic product research and development institutions.

Description

technical field [0001] The invention belongs to the technical field of fish reproduction, and relates to a fish egg hatching device, which is suitable for artificial hatching of various types of fish eggs, and is especially suitable for hatching fish eggs of various famous fishes and ornamental fishes. Background technique [0002] Existing fish egg hatching equipment mainly includes hatching ring road, hatching vat or cement pool. The working principle of the hatching circuit and the hatching tank is to use the action of water flow to wash up the fish eggs to prevent the fish eggs from sinking to the bottom and suffocating to death. The hatching ring is suitable for large-scale commercial production of green carp, grass carp, silver carp, and bighead carp fry, but has disadvantages such as high cost and large water consumption; hatching tanks are mainly used for small-scale production of famous and high-quality fish fry, with heavy structure and low water consumption.

AI Technical Summary

Problems solved by technology

The hatching ring is suitable for large-scale commercial production of green carp, grass carp, silver carp, and bighead carp fry, but has disadvantages such as high cost and large water consumption; hatching tanks are mainly used for small-scale production of famous and high-quality fish fry, with heavy structure and low water consumption. Disadvantages such as large size and low hatching efficiency

Cement ponds are mainly used for small-scale static water hatching of sticky fish eggs such as carp and crucian carp, which have the disadvantages of large floor area and low hatching efficiency

[0003] Various ornamental fishes, as well as American shad, mullet, yellow catfish, loach and many other famous and high-quality fishes, generally have a medium-to-small single-batch breeding scale, require high hatching conditions for fish eggs, and require careful management. The existing hatching environment There are problems such as inconvenient operation and management, large water consumption or low hatching efficiency in equipment such as roads or hatching tanks, which cannot fully meet the hatching requirements of various fish eggs

[0004] In the process of scientific research such as fish species breeding, there is an urgent need for fish egg hatching devices that are portable, flexible, easy to control hatching conditions, wide in scope of application, and low in purchase cost. Existing hatching devices are difficult to meet the needs of scientific research
