Description

Barbarbus barbus barb seedling temporary rearing pond

Technical Field

The utility model provides a pond is supported temporarily to barb barbel seed seedling belongs to fish seed seedling and supports technical field temporarily.

Background

The spinibarbus is also called as Qingbo fish, belongs to the spinibarbus barbus of the subfamily of the spinibarbus of the family Cyprinidae as a high-quality fish in a water system of China, is one of the most main freshwater cultivated varieties at present, and is distributed in each large water system in the south of the Yangtze river of China. The Sinocyclocheilus grahami is active, quick in swimming, strong in snatching ability, cold-resistant and disease-resistant. Under the background that the price of a traditional cultivated variety is reduced and the profit is reduced, the cultivation profit of the barbel barb is obviously increased in temperature, so that the cultivation scale of the barbel barb is obviously enlarged, and the problem of temporary cultivation of seedlings is increasingly prominent.

Generally, the fry breeding and adult fish breeding are performed in separate ponds, and the fry needs to be classified and screened in the process of growing up continuously. In the process of grading screening operation, the loss of seedlings is easily caused by mechanical damage. Meanwhile, the fry rearing pond is generally in an idle state after the fry rearing is finished, and the utilization rate is low.

Therefore, how to design a barb brei fry pond of supporting temporarily, solve the high and fry of the classified screening of barb brei fry in the process of supporting temporarily and cultivate the lower problem of the idle utilization ratio in pond of supporting after accomplishing with the fry, promote the survival rate of supporting temporarily of barb brei fry, improve and breed the surface of water utilization ratio, become the technical problem that technical staff in the field remained the solution.

Disclosure of Invention

To the not enough of above-mentioned prior art, the to-be-solved technical problem of the utility model is: the utility model provides a pond is supported temporarily to barb garrulous millet seed, solve the seed loss height that leads to and the seed cultivation after accomplishing the seed cultivation that the classified screening of the in-process of supporting temporarily and cultivate the lower problem of idle utilization ratio in pond, promote the survival rate of supporting temporarily of barb garrulous millet seed, improve and breed the surface of water utilization ratio.

In order to solve the technical problem, the utility model discloses a following technical scheme:

a temporary culture pond for barbel barb seedlings comprises a seedling culture net cage, a small-size grading screening net enclosure and a large-size grading screening net enclosure, wherein the seedling culture net cage is composed of a net cage with an opening at the upper end, the net cage is formed by sewing nylon net sheets, four corners of the whole net cage are hung on four vertical rods, and goose stone-warming pendants are hung at the four corners of the lower end; the small-size grading and screening net enclosure and the large-size grading and screening net enclosure are the same in structure, the meshes of the net pieces are different, the nylon net pieces of the linked goose warming stone pendant are hung at the lower end of the nylon net pieces to form a rectangle, and four corners of the nylon net pieces are hung by vertical rods.

Preferably, the mesh size of the nylon net sheets of the seedling cultivation net cage is 0.125 cm.

Preferably, the mesh size of the small size grading screening net enclosure net sheet is 0.1 cm.

Preferably, the mesh size of the large-size grading screening net enclosure net sheet is 0.25 cm.

Preferably, the vertical rod is made of bamboo or wooden piles.

Advantageous effects

The utility model relates to a temporary raising pond for barbel barb offspring seeds, which comprises an offspring seed raising net cage, a small size grading screening net enclosure and a large size grading screening net enclosure, wherein the offspring seed raising net cage comprises a net cage with an opening at the upper end, the net cage is formed by sewing nylon net sheets, four corners of the whole net cage are hung on four vertical rods, and goose greenstone is hung at four corners of the lower end; the small-size grading and screening net enclosure and the large-size grading and screening net enclosure are the same in structure, the meshes of the net pieces are different, the nylon net pieces of the linked goose warming stone pendant are hung at the lower end of the nylon net pieces to form a rectangle, and four corners of the nylon net pieces are hung by vertical rods. Temporarily culturing the seedlings in the seedling culturing net cages, and directly placing the seedling removing boxes into a small-size grading screening net enclosure after the temporary culture is finished; after the seedlings grow up, removing the small-size grading screening net enclosure, entering the large-size grading screening net enclosure, and performing centralized temporary culture and feeding on the seedlings, so that the survival rate is higher; the temporary fry rearing and adult fish rearing are integrally operated, so that the water surface utilization rate is greatly improved; compared with the traditional classification screening, the operation of removing the box and the net enclosure step by step has less mechanical damage and low fry loss.
