This enhances the effectiveness of hormonal sex-reversal and reduces cannibalism. "We are happy with the recent signing of this agreement for . why is there no mayor humdinger toy. As tilapia grow-out systems intensify, demand for all-male fry or fingerlings increases. This improves seed productivity and also synchronizes spawning, even when clutch removal is practiced. All-male stocks, therefore, give rise to larger fish of uniform size that fetch higher market prices. The ideal population size is infinitely large, ensuring no loss of genetic variation. . A thorough understanding of these methods is needed to start a productive hatchery. However, tilapia females spawn asynchronously, producing only about 2,000 eggs per clutch. Meanwhile, the ideal sex ratio is 3:1 up to 7:1.
