Under certain conditions, ovulation and plasma gonadotropin levels can be stimulated by ovarian fluid from other ovulated females. The African catfish, Clariasgaricpinus, is an example. It lives in muddy water and spawns at night, conditions expected to favor pheromone commimication. Moreover, this species is a seasonal breeder, spawning after rainfall. The sudden mass spawning requires synchronization. Water from males or ovulated females, and also ovarian fluid of ovulated females, experimentally induced ovulation in 67% of females. Plasma gonadotropin was also increased by these treatments (Resink etal., 1989c).

The African catfish (Clarias gariepinus) is native to subtropical Africa but is now cultured across the planet. Males and females of this species spawn as pairs in flooded vegetation in turbid waters and appear to use pheromones to locate and identify each other. 

Can be defined as weight or mass increase with age in a multiplicative way (from Medewar, R, Size, shape and age, in Essays in Growth and Form Presented to D Arcy Wentworth Thompson, Clarendon Rress, Oxford, UK, 1945, p. 708, as cited by Smith, R.W. and Ottema, C., Growth, oxygen consumption and protein and RNA synthesis rates in the yolk sac larvae of the African catfish Clarias gariepinos).
