Problems solved by technology

[0003] However, after the introduction of the large barb fish species in my country, the existing seed culture is usually directly through the outer pond when the fry are 2-3cm. The specific growth conditions are carefully managed, resulting in uncontrollable yield, low survival rate and high input costs, especially the unreasonable use of feeding feed and inappropriate feeding methods, which are not conducive to its rapid growth

Abstract

The invention discloses an industrial culture method of barbus capito seedling, which comprises the following steps of: A, throwing fish fries, namely throwing fries of 2-3cm in size into a cement pond; B, feeding with microcapsule feed at time, and feeding rotten chicken manure once a week into the pond; C, dividing the pond, namely dividing the pond when the fries grow to 9-10cm, putting a halffries in the total amount of the fries into a new cement pond with the same specification, wherein the water quality of the new cement pond and the old cement pond is the same, and simultaneously sterilizing the old water pond by adopting quicklime; D, feeding in separate ponds at time after the ponds are divided, and driving fish flock after feeding for half an hour each time; E, finishing seedling raising when the fries grow to 15cm. The method has the advantages that the fish body constitution is improved through rotten chicken manure feeding, quicklime sterilizing and driving breeding, thehigh survival rate is ensured, the fast growth of the fish fries is ensured, the purpose of fine management is achieved, the controllability of the yield is ensured and the investment cost is reduced.

Description

technical field [0001] The invention relates to a method for cultivating large barb, in particular to a method for cultivating large barb seedlings. Background technique [0002] The giant barb belongs to the family Cyprinidae, the subfamily Cyprinidae, and the genus Barp. It is a euthermic fish with delicious meat, fast growth, strong stress resistance, and salt-alkali tolerance. It has excellent properties such as wide appetite, fast growth, delicious meat, salt and alkali resistance, and strong adaptability. It is more cold-resistant than Chinese barbed barb, light spiny barb, black scale barb, and money barb, which enriches the cultured species of barb in northern my country. [0003] However, after the introduction of the large barb fish species in my country, the existing seed culture is usually directly through the outer pond when the fry are 2-3cm. Careful management of specific growth conditions leads to uncontrollable yield, low survival rate and high input costs...
