Catfish culture, whether intensive or polyculture, is generally fed 2 to 4 times a day. Increasing the feeding frequency and feeding a small number of meals will be beneficial to the digestion and absorption of channel catfish, and avoid metabolic disorder caused by excessive feeding, which will lead to intussusception of channel catfish. Generally, the culture cycle of Japanese catfish fed with heavy feed is 1.5 ~ 2 years, with fish released in March ~ April in spring and sold in April ~ May in the following year. Expanded materials can effectively shorten the breeding cycle. Similarly, fish released in March and April in spring can reach the market specifications before stopping feeding, 4 to 5 months earlier than feeding heavy materials.
