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

Embodiment 1

[0028] A method for artificial seedling cultivation of spotted porpoise, is characterized in that, comprises the following steps:

[0029] (1) Select the rectangular cement pond as the fish fry cultivation pond, and its area is 3m 2 , with an aspect ratio of 3:1 and a depth of 78cm;

[0030] (2) select the fish fry with a length of 1.1cm and put them into the culture pond, feed rotifers and cultivate them, wherein, feed 5 times a day, feed once every 5 hours, each feeding weight is 7% of the fry body weight, and aerate and absorb dirt ;

[0031] (3) Cultivate until the fry length is 2cm, feed copepods, and inflate until the water surface is slightly tumbling, absorbing dirt, cultivate until the fry length is > 3cm, and obtain fish species.

[0032] In the culture pool, a No. 100 air stone is set every 0.5 square meters.

[0033] The pool water is natural river water that has been settled, filtered and sterilized.

[0034] The pool water has a dissolved oxygen content of 7....

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.
