Artificial breeding method for yellow catfishes

Abstract

The invention provides an artificial breeding method for yellow catfishes. The method comprises the following steps of pond selection, wherein a pond which is good in water filling and drainage condition, 20-25 cm thick in silt and average 2 m deep in water is selected as a breeding pond; pond sterilization, wherein bleaching water is splashed in the whole pond 20 days before fry are put, after sterilization is conducted for 3 days, new water is changed to reach 2 m, and fertilizer is applied to pond water; fry putting, wherein 10,000 yellow catfishes are put every two days for three times, 3%-5% of a salt solution needs to be soaked for 5-9 min for sterilization 10 h before the fry are put; daily management, wherein from the first day to the 20 day, feed for the fry is put 3-5 times each day, after the 21<st> day, feed for adult fishes is put 6-7 times each day, and soybean milk is splashed to promote reproduction of zooplankton every morning and night. The yellow catfishes bred through the method are high in survival rate, yield and growth rate. The feed for the adult fishes is added with the traditional Chinese medicines of pollen pini, American ginseng, spirulina and hawthorn fruit powder, the immunity of the fished can be improved, and the digestive systems of the fishes are improved.

Description

technical field [0001] The invention relates to the field of culture technology, in particular to an artificial culture method of yellow catfish. Background technique [0002] Yellow catfish, commonly known as yellow spicy ding, Ang thorn fish, is a species of the genus of the genus Peeled catfish. Mainly distributed in the Yangtze River in China. Mostly active in still water or slow-flowing rivers, like bottom dwelling life, inhabits the bottom of the lake during the day, and swims to the upper layer of the water to look for food at night. It has strong adaptability to the environment, so it can live in adverse environmental conditions. [0003] Now, in many places in China, there are yellow catfish farming, but due to different regions, different environments, and different temperatures, the methods must be different. However, our country has a vast territory, and the farming methods in many places are relatively the same. It is easy to cause many unnecessary troubles, ...

[0003] Now, in many places in China, there are yellow catfish farming, but due to different regions, different environments, and different temperatures, the methods must be different. However, our country has a vast territory, and the farming methods in many places are relatively the same. It is easy to cause many unnecessary troubles, and often may cause slow growth of fish, decline in production, etc.
