Aspects of the reproductive biology of Tilapia guineensis was carried out in the laboratory.  Twelve ripe male and female brooders of T. guineensis  (body length, 12.2 - 12.9cm and weight, 100 – 130g) paired 1@:  in triplicate were made to spawn naturally in glass aquaria (60 x 30 x 30cm3). Results show mean fecundity to be 1,269 eggs per female spawner with mean egg size of 1.48mm. Hatching of eggs started 47-48hours after fertilization at a mean temperature of 27.40C. Percent hatch was 74.8% and length of hatchling as 3.8mm.  Time of yolk sac absorption was observed to be 4 days with swim-up fry length, 5.7mm and weight, 1.67mg. Parental care was prominently displayed by both parents.


Keywords:  Tilapia guineensis, reproduction, aquaria, brackish water.
