A Research on Growth and Meat Quality Parameters and Economic Conversion Rates of Different Feeding Regimes Applied to Cultured Large Rainbow Trout (Oncorhynchus mykiss) in Net Cages in the Black Sea

This study aimed to determine the effects of different feeding regimes applied to large commercial rainbow trout (Oncorhynchus mykiss) with an initial weight of 1045.12±43.51 g in the Black Sea on growth, meat quality performances, and economic conversion rates. The study was conducted in a commercial fish farm in the Sinop district of the Southern Black Sea (Turkey). Fish were grouped according to three different feeding regimes (R group fed according to feeding table (1% fish weight); D group fed 1 day/fasted 1 day; E group fed 6 days/fasted 1 day) and fed twice a day for five months. At the end of the 150-day study, it was found that the R and E groups had the best growth parameters (weight gain, specific growth rate, and thermal growth rate) and these results were statistically different from the D group (p
