Reproductive characteristics of catfish

Catfish can reach sexual maturity at the earliest age 1, but only some of the faster-growing individuals (the most mature ones) The small ones are: female fish with a body length of 22.4cm and a weight of 51g; male fish with a body length of 17.8cm and a weight of 34g), accounting for about 50 of the group, and all 2-year-old individuals are sexually mature. In the natural environment, its breeding season is from April to July, and the optimum water temperature for spawning is 9 to 30°C.

Catfish has a special spawning type. The development of oocytes in its ovaries is synchronous, but they are not produced in the same batch, but are produced multiple times. Under artificial conditions, one broodstock can induce labor 3 to 4 times a year, with an average of about 2,000 eggs each time. The total number of eggs laid annually is slightly lower than the number of eggs conceived. The diameter of eggs laid in the later stages of reproduction is slightly smaller than that of eggs laid in the early stage.
