This study is the first spawning and larval rearing of the F-1 hybrid striped bass (Morone chrysops female X M. saxatilis male) grown in culture conditions in Turkey. The F-1 Hybrid striped bass was fed with commercial pellet feed in floating net cages. They reached the sexual maturity at two years old. Female brood fish were given 30 mu g/kg of LHRH-a (Lutenizing hormone releasing hormone analogue) and male fish given 10 mu g/kg; of CHP(Dried carp pituitary), 4 mg/kg was used for the female and half that amount for the male for induced breeding. The fish injected LHRHa were successfully induced to both strip spawning and tank spawning by a single hormone injection. However, fish injected CPH and saline, untreated control did not spawn. Latency period was found to be 20.41 +/- 0.91 hour. In term of fertilization rate, larval deformity rate no significant difference was found between tank spawning and strip spawning (p>0.05). Fertilization rates ranged from 56.3% to 85.4% and hatch rates were between 0.99% and 46.88%, whereas the level of larval deformities ranged between 81.25% and 100%.
