High-survival-rate weever fry breeding device and method

Abstract

The invention provides a high-survival-rate weever fry breeding device and method. The device comprises a water inlet pipe, a water draining pipe, a fixing support, oxygen increasing pumps, a breedingpond, a feeding tank, a warm lamp, a rotating shaft, rotating wings, an activated carbon filtering screen plate, and a heat preservation covering film. The water draining pipe is mounted below the water inlet pipe; the right end surface of the water inlet pipe is connected with breeding pond; the fixing support is installed on the upper end face of the breeding pond; the warm lamp is installed onthe lower end face of the fixing support; the inner wall of the breeding pond is covered with the heat preservation covering film; the oxygen increasing pumps are mounted at the upper side in the breeding pond; the feeding tank is mounted at the right sides of the oxygen increasing pumps; the rotating shaft is mounted at the lower ends of the oxygen increasing pumps; the rotating wings are mounted at the lower end of the rotating shaft; and the activated carbon filtering screen plate is mounted the lower side of the interior of the breeding pond. According to the high-survival-rate weever frybreeding device and method, the problem of the poor breeding effect of an existing weever fry breeding device can be solved, and the weever fry breeding device is reasonable in structure, convenientto assemble and mount, good in breeding effect, and high in practicality.

Description

technical field [0001] The invention relates to a perch seedling raising device and method with a high survival rate, and belongs to the technical field of seedling raising devices. Background technique [0002] Perch, also known as flower perch, Zhaihua, perch board, four-rib fish, etc., commonly known as perch, is listed as "China's four famous freshwater fish" together with Yellow River carp, mandarin fish and Heilongjiang Xingkai Lake big white fish. my country's perch species are mainly Songjiang perch, also known as four-gill perch, also known as tiger head fish. Bass, body length and side flat, lower jaw longer than upper jaw, firm meat in the shape of garlic cloves, swim bladder can be used to make fish maw, often steamed and eaten. Bass meat is white and tender, with few thorns, no fishy smell, very delicious taste, rich in protein and vitamins, and can be used as medicine. It is an extremely precious tonic. The general body length is 30-40cm, and the weight is 40...
