Abstract

This study was carried out to investigate the growth data, egg production and changes in the biochemical structure of meat of Abant trout depending on feeding frequency (once a day, twice a day, three times a day, four times a day) in order to contribute to the economy through the private sector. All fish in the groups were planned to be of similar weight at the beginning of the study. Individual fish weights were measured at the beginning of the study, and the average was found to be 224.87 ± 0.69 g. At the end of the study, the weights of the fish groups that were fed differently were 536.77 ± 37.46 g, 693.52 ± 67.53 g, 770.47 ± 37.29 g, and 810.63 ± 42.09 g, respectively. The absolute numbers of eggs taken per brood from the once meal group to the four-time meal group were found as 707 ± 38, 999 ± 77, 1036 ± 110, and 1053 ± 60 eggs/broodstock, respectively. In terms of fatty acids, which are an important contributor to meat quality, the second, third, and fourth meal groups were found to be advantageous compared to the first meal group. According to the data obtained at the end of this study, which lasted 392 days, it was seen that the groups which received meals twice, three times, and four times could be cultured by the private sector because of the good results. Especially the three-time meal group yielded the best results in terms of growth, egg production, biochemical data, and meat quality. It has been concluded that breeding and species-specific feed production studies will contribute to the cultivation studies.
