| Abstract | To evaluate the effects of betaine on broodfish, reproductive performance and eggs’ quality based on seed output were carried out. An experiment was with four betaine levels (0.0, 0. 0 5, 0 .1 , 0 . 1 5%) w as established. Betaine levels were dissolved in 100 cc distilled water, and then pulverized over the feed separately . Eggs w ere harvested from the mouths of females in 5 - day interval and incubated in tray - based hatchery. The productive performance s were evaluated on the total number of eggs, percentage of fish spawning, percentage of relative fecundity, percentage of egg fertiliza tion and percentage of egg hatchability. The quality of eggs was measured and examined under binocular microscope. The results showed that high water temperature lead s to decrease in seed production of Nile tilapia, especially in dry season. Betaine supple mentation in various levels did not influence on Nile tilapia females’ reproductive performances. The total number of eggs, percentage of fish spawning, absolutely fecundity and relative fecundity were not influenced by betaine levels. The percentage of eg g fertilization and hatchability were not influenced by betaine levels. However, broodfish that were fed by 0. 0 5% level of betaine showed better response than other levels, comparatively. |
