Problems solved by technology

At present, these two types of Schizothorax have become popular characteristic breeding species in mountainous areas such as Chongqing, Sichuan, Yunnan, and Guizhou. However, due to the lack of research on fry breeding methods and farmers entering After the fingerling stage, conventional breeding methods are used to raise them, so that the survival rate of fry cultivation is low and the breeding cycle is generally long in the cultivation of Schizothorax full mouth and Schizothorax fine scales

Embodiment Construction

[0025] The present invention will be described in detail below in conjunction with accompanying drawing:

[0026] 1. Selection of aquaculture water: choose underground spring water as the aquaculture water source, water quality requirements: water temperature 13-21 ℃, dissolved oxygen above 6mg / L, ph value 6.5-7.8, other indicators meet fishery water quality standards.

[0027] 2. Construction of breeding ponds

[0028] (1) Fry cultivation pool. Splash to Wuzi stage: The area of ​​the single-mouth pool is 10 square meters, length × width × depth = 5.0m × 2.0m × 0.6m, water enters from the middle of one end of the pool width, and the water exits from the other end, the slope from the inlet end to the outlet section 3.0%, the inner wall of the pool is covered with white tiles, and the water inlet and outlet are equipped with filter and anti-escape nets, and the water intake can be adjusted.

[0029] Wuzai to Cuntian stage: the area of ​​single-mouth pond is 30-50 square meters...

Abstract

The invention discloses a schizothorax intensified and quick breeding method. Staged separated breeding is performed, and the aquatic water environment is continuously kept within a range appropriate for growth of schizothorax, so that ingestion and growth all the year round are realized; various kinds of fry bait are matched scientifically and reasonably to meet the growth requirements of schizothorax, so that the rate of survival in fry cultivation reaches about 90%, the breeding period from the fries to marketable fishes is shortened to about 2.5-3 years, the sizes of marketable fishes are consistent, and during the cultivation and breeding, no serious disease or loss is caused; besides, the method is simple to study, popularize and master, and has the advantage of high cultivation benefit (the input-output ratio is 1:5), and has huge application value and positive significance in promoting income increase and wealth acquisition at impoverished mountainous areas.

Description

technical field [0001] The invention relates to a method for rapid fish cultivation, in particular to an intensive and rapid cultivation method for Schizothorax. Background technique [0002] Both Schizothorax chinensis and Schizothorax slenderscale belong to the subfamily Cyprinidae Schizothorax, and are important cold-water economic fish endemic to China. Because of its fresh and tender meat and high nutritional value, it is a rare and high-quality fish species in the production area. In the area of ​​Ya'an, Sichuan, Schizothorax is known as "Yayu". In Wuxi, Chongqing, Schizothorax and Schizothorax are collectively called "Wuxi Yangyu". Logo Protection Certification. At present, these two types of Schizothorax have become popular characteristic breeding species in mountainous areas such as Chongqing, Sichuan, Yunnan, and Guizhou. However, due to the lack of research on fry breeding methods and farmers entering After the fingerling stage, conventional breeding methods ar...
