Induced breeding technology has been successfully demonstrated for both sexes of commercially important freshwater fishes, except that of male catfish (Clarias batrachus), commonly known as magur. 8. However, it has not been widely practiced since 1987 due to the replacement of Clarias batrachus in the culture system by the hybrid. 1971. 1975. Clarias batrachus is not a territorial species, unless an intruder makes an attempt to raid its nest during the mating season.

January 26, 2016 notes that the walking catfish is threatened and is becoming critically endangered in its native range in Asia (2013). I cannot confirm that. But due to prolific breeding ability, excessive acclimatization in the Indian condition and simplicity in rearing, this exotic species has compelled the fishermen in Bihar and other states of India to culture it on large scale, . Typically, larvae weigh approximately 0.00186g upon hatching. The increase in stocking density decreased the total weight, specific growth rate (SGR) and percent weight gain of Clarias larvae during a 13‐day experiment. The Asian catfish, Clarias batrachus (Linnaeus, 1758), is a highly valued species endemic to India that is currently in drastic decline in most of its natural habitat.

Opegaster is the most prevalent trematode parasite in the walking catfish and it predominately inhabits the gut and gall bladder. The female will return once the eggs have hatched and the male and female take part in protecting the fry until they are independent.
