Christian Larbi Ayisi

The Cichlidae family is in the order perciformes. The fish family Cichlidae presents an array of fishes with great diversity. Production of eggs and fry in tilapia are affected by several factors within its environment which includes temperature, day length, density and sex-ratio of broodstock, length and/or weight of breeders, food quality, and stress as well as the water quality (oxygen, salinity, pH etc.) but also the overall spawning capacity of a group. The mating system of the African cichlid fish Oreochromis mossambicus resembles that of other lekking animals; males defend mating territories where the spawning pits they dig are sites only for mating and oviposition and are not used for rearing offspring.
