1), magnitude of decrease in daily growth was 51.21%. Increase in stocking density resulted in reduction in size at maturity in both the sexes (male: 2 to 7.5%; female: 1.37 to 5.57%), reduction in fecundity (25 to 31%), fry production (18.58 to 28.58%) and inter-spawning interval (25 to 40%). At a living space of 597 cm 3 /fish (40 fish aquarium1 ), though males constructed the nest, females failed to spawn as post
