Artificial seedling growing method of mystus guttatus

Abstract

The invention relates to a vertebrate culture technology, and specifically relates to an artificial seedling growing method of mystus guttatus. The method comprises the following steps: selecting a rectangular cement pool as a fry culture pool, wherein the area of the pool is 2 to 5m<2>, the length-breadth ratio of the pool is 3-3.2:1, and the depth of the pool is 70 to 80cm; selecting fry with a length of (1+ / -0.2)cm for putting into the culture pool, feeding the fry with rotifers for cultivation, and performing inflation and sewage suction; and when the fry is cultivated to a length of 2-3cm, feeding the fry with copepods, performing inflation until the water surface tumbles slightly, performing the sewage suction, cultivating the fry into a length greater than 3cm, obtaining fish fingerlings. According to the invention, the survival rate of the fry is high, the growth stability is high, the seedling growing cost is low, and the labor investment is small.

Description

technical field [0001] The invention relates to a vertebrate breeding technology, in particular to a method for artificial seedling cultivation of the spotted porcupine. Background technique [0002] Spotted carp is a species of the genus Carpiaceae. It enjoys the reputation of "King of Freshwater" and "Four Famous Fishes of the Pearl River". Its meat is tender, delicious, and has high nutritional value. The prospect of popularization, but its quantity is scarce, can't meet the market demand, therefore, artificial breeding technology provides a new way for the mass production of spotted porcupine. [0003] In the prior art, such as the literature "Growth, Breeding, Feeding Habits and Breeding Techniques of the Spotted Catfish" (Li Hongjing, Chu Zhangjie, Hubei Agricultural Science, 2006, 45 (6): 807-809), "Cultivation of Wild Spotted Catfish Seedlings" Experiment" (Li Daoyou, Zhang Zhuqing, Zhou Lu, etc., Guizhou Animal Husbandry and Veterinary Medicine, 2013, 37(3): 67-68)...

Problems solved by technology

[0002] Spotted carp is a species of the genus Carpiaceae. It enjoys the reputation of "King of Freshwater" and "Four Famous Fishes of the Pearl River". Its meat is tender, delicious, and has high nutritional value. The prospect of popularization, but its quantity is scarce and cannot meet the needs of the market. Therefore, artificial seedling breeding technology provides a new way for the mass production of spotted porcupine

[0003] In the prior art, such as the literature "Growth, Breeding, Feeding Habits and Breeding Techniques of the Spotted Catfish" (Li Hongjing, Chu Zhangjie, Hubei Agricultural Science, 2006, 45 (6): 807-809), "Cultivation of Wild Spotted Catfish Seedlings" Experiment" (Li Daoyou, Zhang Zhuqing, Zhou Lu, etc., Guizhou Animal Husbandry and Veterinary Medicine, 2013, 37(3): 67-68), "Artificial Cultivation Technology of Spotted Puffer Fish" (Yang Jiajian, China Aquatic Products, 2002(2): 42-43 , 57), all have carried out in-depth research on the breeding of spotted carp, but the development of artificial breeding technology of spotted carp is relatively short, and there are still the following problems: ①The environmental water temperature control range for the cultivation of spotted carp fry is too large, which affects the survival of fish fry cultivation ② The setting of fry density in the breeding pond is unreasonable. If it is too large, it will affect the survival rate of fry. If it is too small, it will not be able to make full use of the water space, thereby reducing the yield of fish fry and increasing the cost of cultivation.
