Conventionally, in the artificial reproduction of catfish, we have about 35% of the high performing catfish fingerlings, 45% of average performing fingerling and 15% of very low performing fingerlings and 5% to mortality.

However, this may not be the case everywhere and all the time.

This question would help know if crossing breeding of two high performing adult catfish would result to the production of greater percentage of high performing catfish fingerlings.

N:B high performing or performance as used in this context, referrs to increase in size.
