The Effect of Using Wheat Protein at Different Ratios Instead of Fish Meal on Growth Parameters and Fatty Acid of Juvenile Sea Bass (Dicentrarchus labrax L. 1758)

Abstract

In this study, a feeding experiment was conducted using different rations (25%, 50%, 75%, and 100%) of wheat flour protein instead of fishmeal in fry fish (Dicentrarchus labrax) feeds. In the experiment, an average weight of 2.33±0.2 g juvenile seabass was used. Seabass fries were fed with the experimental feeds for 60 days. The experiment was designed in triplicates. At the end of the experiment, the growth parameters and fatty acid composition of fish fries were examined. As a result, it was statistically determined that the use of wheat flour protein at a high rate had a negative effect on the growth parameters of the fish. Significant changes in fatty acid composition were also observed.
