Özet
This study was conducted to determine the seasonal variation in biochemical composition of the veined rapa whelk, Rapana venosa caugth by beam trawl (Algarna) in the Blach Sea. R. venosa samples were obtained from fishermen who fishing off Yakakent at Samsun province in the Black Sea between December 2014 and November 2015. Homogenised dired veined rapa whelk meats were used for crude protein, crude oil and crude ash analyzes. Mean crude ash values was the highest in winter (2.91 +/- 0.134%) and the lowest in spring (2.37 +/- 0.051%) (P<0.05). The mean lipid values were not statistically difference among the seasons (one way ANOVA, P > 0.05). The mean crude protein values were also not statistically difference among the seasons (P>0.05). Mean dry matter values was the highest value in winter (31.33 +/- 0.448%) and the lowest in spring (30.01 +/- 0.280%). The dry matter values in winter was also statistically higher than spring (P<0.05). Food availability, plankton composition, temperature, reproduction activities, analysed tissues such as gonad, digestive gland, foot and mantle are the importent factors effect the biochemical composition of rapana. Thus, these factors should be take into account in the future studies.
