Acrossocheilus fasciatus spawning pond

Abstract

The invention discloses an acrossocheilus fasciatus spawning pond. The acrossocheilus fasciatus spawning pond comprises a parent fish pond and a separating pond. A spawn collecting pond is arranged at the bottom of the parent fish pond, a spawning bed is arranged between the parent fish pond and the separating pond and paved with gravel, and gaps are reserved between the gravel so that spawn granules can enter the spawn collecting pond along with water flow and parent fish can be stopped above the spawning bed. A water inlet is formed in the upper portion of the parent fish pond, a drainage spawn collecting pipe is arranged at the bottom of the spawn collecting pond, and a vertical pipe and an inverted-U-shaped pipe are arranged on the drainage spawn collecting pipe. An overflow port is formed in the separating pond, and a spawn taking valve is arranged at the bottom end of the separating pond. According to the acrossocheilus fasciatus spawning pond, after being laid by parent fish in the parent fish pond, spawn granules rapidly penetrate through the spawning bed and enter the spawn collecting pond along with water flow, so that it is avoided that spawn granules are devoured by parent fish; due to the design of the separating pond, zygotes can be easily, conveniently and efficiently collected, the high-intensity operation of fishing for zygotes manually is relieved, and interference with the spawning behavior of parent fish is avoided. The acrossocheilus fasciatus spawning pond is simple in structure and low in cost and saves time and labor, the spawning rate and fertilization rate of parent fish exceed 90%, and the zygote collecting rate reaches 98% or above.

Description

technical field [0001] The invention relates to the field of breeding freshwater fish, in particular to a spawning pool for bald-lipped fish. Background technique [0002] The light-lipped fish (Acrossocheilus fasciatus), commonly known as grouper, is distributed in the mountainous areas of southern my country. It lives in mountain streams with clear water and gravel bottoms and rapids in the upper and middle reaches of rivers. It spawns when the water temperature is 18-27°C. The spawning season It is generally from May to August, and the peak breeding period is from June to July. It is a rare and valuable economic fish in streams and has great development and utilization value. [0003] In the artificial breeding of bald-lipped fish, most of the open containers filled with gravel are placed at the bottom of the spawning pond, and the broodstock lay eggs on the gravel for insemination, and the fertilized eggs are manually separated from the gravel and transferred to the hatch...

AI Technical Summary

Problems solved by technology

[0004] In view of this, the present invention provides a spawning pond of bald-lipped fish to solve the problems of large loss of fertilized eggs in the artificial breeding of bald-lipped fish, time-consuming and laborious manual retrieval of fertilized eggs, and interference with broodstock to reduce spawning
