Effects of frequency of eggs and fry harvest on seed production and growth of Nile tilapia

Abstract: This study analyzed the potential of harvesting eggs and fry at different time intervals for improved seed production of Nile tilapia. Broodstock were put in 3x1m2 hapas at a sex ratio of 3 females: 1male. Eggs and fry were harvested at intervals of 8 days, 10 days, 12 days and 14 days respectively. The results showed a direct positive relationship between the harvesting frequencies and total seed production, where Broodfish in the 14 days treatment produced the highest total seed output (13979 ± 314) followed by 12 days (10167 ± 248), 10 days (6645 ± 135) and 8 days (4509 ± 112) respectively. The 8 days harvesting frequency consistently recorded zero swim up fry throughout the study while the 10 days treatment yielded the highest egg counts of 4272 ± 127. The specific growth rates and condition factors of females did not significantly differ among all the treatments.
