Black Sea trout (Salmo labrax) is one of the promising Salmonid species for these purposes considering increased demand for this species in the aquaculture sector. In this research, triploid Black Sea trout were treated with heat shocks during reproduction and triploidy of obtained trouts were identified with different techniques. For this reason, heat shocks were applied at 26.5°C, 28°C and 36°C temperatures for 10 minutes during 30th minute of fertilization and triploidy was determined with fragment analysis, flow cytometry and classic hematological methods. Results indicate that all three temperatures were suitable for the successful reproduction of Black Sea trout. However, 26.5°C gives better results considering both the triploidy success and survival rates. Besides, all three determination techniques especially erythrocyte size measurements and flow cytometry can be used in evaluating of triploidy in Black Sea trout with precise results.
