What is breeding of fish?
Fish breeding is the process of producing young ones from parent brood fish for ensuring species continuity and survival. In aquaculture, fish breeding has been proven to be one of the most desired areas of aquaculture, managing to secure the industry profitability of some pond and cage farms.
How did catfish reproduce?
Male and female channel catfish mate during the spring and summer by swimming together and releasing the eggs and sperm into a nest built by the female or both the male and female. After mating has occurred, the male chases away the female and then goes on to guard his eggs until they hatch.
