The main objective of the reproduction is to maintain the existence of the species and therefore fish have a strategies and tactics to achieve this objective. The reproduction behaviours are important to be studied in relation to know the population dynamic of fishes and their spawning seasons.

This paper reviews the reproductive strategy, fecundity and spawning frequency of fishes. Keywords : Fecundity; Spawning frequency; Gonadal development; Synchronous; gonadosomoatic index
