Seasonal Variation in Biochemical Composition o ISSN:1307-3311 f the Veined Rapa Whelk, Rapana venosa (Valenciennes, 1846) Caugth By Beam Trawl (Algarna) in The Black Sea
Abstract
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.
