Andrias outdoor ecological breeding pond and breeding method

Abstract

The invention discloses an andrias outdoor ecological breeding pond and breeding method. The breeding pond comprises a pond body and a plurality of andrias habitat caves distributed at intervals alongthe upper edge of the pond body, the bottom of the pond body is of a pot bottom shape, the depth of the center of the pond body is 120-150 centimeters, the center of the bottom of the pond body is provided with a dirt collection pit and a sewage discharging pipe, and the portion, close to the edge of the pond, of the pond body is provided with an impeller-type aerator; the entrance of each andrias habitat cave is provided with a movable flashboard. The breeding method comprises the steps that fries of spotted silver carps, silver carps, carps, grass carps and other conventional aquacultured fishes are put into the pond body to serve as fish baits of andrias, when the bait fishes grow to the size suitable for 1-year-old andrias larvae or older andrias larvae to swallow the bait fishes, theandrias larvae are stocked, mixed breeding of the bait fishes and andrias is achieved, and andrias eat the bait fishes; the breeding method also comprises water quality management, water temperatureadjustment and breeding management of the fish baits and andrias in four seasons. The andrias outdoor ecological breeding pond and breeding method can improve the degree of large-scale breeding of andrias, reduce the breeding labor cost and andrias feeding cost, can make andrias grow in a natural ecological environment, and can improve the quality and taste of the meat of andrias.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and relates to an outdoor ecological breeding pond for giant salamanders, and at the same time relates to an outdoor ecological breeding method for giant salamanders. Background technique [0002] Chinese giant salamander (Andrias davidianus), commonly known as giant salamander, is the largest amphibian in existence and has high economic value. In recent years, with the successful research and development of giant salamander artificial propagation technology and another breakthrough in giant salamander imitation ecological reproduction technology, the reproductive rate of giant salamander has been greatly improved, and giant salamander seedlings have been supplied in large quantities, which in turn has boosted the rapid development of giant salamander industry. In the development of the giant salamander industry, commercial giant salamander farming is basically an indoor farming model. Altho...

AI Technical Summary

Problems solved by technology

Although the indoor breeding mode is easy to manage, it has always had the following shortcomings: 1. The construction cost of the indoor breeding pond is relatively high, and the scale is limited. 2. The cost of bait and management is relatively high. 4. The meat quality of giant salamanders has declined, 5. High-density feeding can easily lead to frequent salamander diseases
