Aims: The goal of this research was to investigate the impact of grape seed extract on some biochemical parameters of rainbow trout (Oncorhynchus mykiss) with an average weight of 42.5±1.44g.
Methods and Results: Fishes were fed with diets containing 0%, 0.5%, 1% and 1.5% of grape seed extract (GSE) during 42 days. At the end of the experiment, kidney, spleen, muscle and liver tissues were taken from fish and total protein, total lipid and total carbohydrate levels were determined.
Conclusions: The total protein levels of 0%, 0.5%, 1% and 1.5% group were increased importantly by dietary GSE supplementation (p<0.05). On the other hand, the total carbohydrate and total lipid levels were not significantly affected by the dietary level of GSE in all tissues.
Significance and Impact of the Study: In conclusion, we demonstrated an improvement of total protein, total lipid and total carbohydrate parameters of Oncorhynchus mykiss by dietary GSE supplementation.
