Description

Fish shoal roe hatching apparatus for fish protection

Technical Field

The invention relates to the technical field of fish egg incubation, in particular to a fish school and fish egg incubation device for fish protection.

Background

The rough-skinned weever is coastal migratory fish, can grow in saline water and pure fresh water, is a Chinese national secondary protection animal, is endangered because of excessive hunting, and migration is cut off, and the water source pollution that continuously increases influences the living environment of weever, and the yield of the rough-skinned weever is less and less, and the quantity of the rough-skinned weever in the wild environment can be effectively helped to recover through artificial incubation of rough-skinned weever fry, so that the rough-skinned weever protection work is facilitated.

Present roe hatching apparatus often needs to fish out the fry in the hatching apparatus through the diddle net after the roe hatching, place in the container that holds water, and the diddle net frequently stirs in hatching apparatus, make the fry receive the frightening easily, thereby make the fry acutely move, lead to the survival rate of later stage fry to reduce, and in time use the manual work of diddle net to select and drag for the fry, also can't be with the roe of hatching failure and the better separation of fry, water quality in the roe corrupts the pond of growing seedlings in order to avoid hatching failure.

Disclosure of Invention

In order to overcome the technical problems, the invention aims to provide a fish school egg hatching device for fish protection, which is characterized in that a holding rod, the holding rod and a supporting arm are arranged, the holding rod is held and pulled upwards, two bottom plates are turned upwards and matched with side plates to close a bottom end opening of a carrying box, the holding rod is conveniently pulled to communicate the carrying box with a water body in the carrying box and carry fish fries together, carrying and fry collecting of the fish fries after fish egg hatching are facilitated, frightening and damage to the fish fries in the fry collecting and carrying processes are reduced, the subsequent survival rate of the fish fries is improved, the first bottom frame and the second bottom frame are conveniently replaced through the arrangement of elastic buckles, the first bottom frame and the second bottom frame, the fish eggs can conveniently pass through the second bottom frame, the fish fries and the fish eggs which are not hatched are separated, water in a fry breeding pond is prevented from being damaged by the fish eggs, upward microflow is formed in a water tank through the arrangement of a water, therefore, the fish eggs are slowly rolled in the placing frame, fertilized eggs are prevented from being deposited and placed on the sand net on the bottom frame for a long time, and accordingly saprolegniasis is obtained, and the hatchability of the fish eggs and the quality of fish fries are improved.

The purpose of the invention can be realized by the following technical scheme:
