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.

Bu çalışmada, Karadeniz’de algarna ile avlanan deniz salyangozunun, Rapana venosa, biyokimyasal kompozisyonunun mevsimsel değişimi araştırılmıştır. Deniz salyangozu örnekleri Aralık 2014 ile Kasım 2015 tarihleri arasında Karadeniz’in Samsun ili Yakakent ilçesinde avlanan balıkçılardan elde edilmiştir.  Kurutulmuş deniz salyangozu numuneleri homojenize edilerek ham protein, ham yağ ve ham kül analizi için kullanılmıştır. Ortalama ham kül değeri en fazla kış mevsiminde (%2,91±0,134), en düşük ilkbahar mevsiminde (%2,37±0,051) (P<0,05) tespit edilmiştir. Ortalama ham yağ miktarlarının mevsimler arasında tespit edilen istatistiki fark önemsiz çıkmıştır (one way ANOVA, P>0,05). Mevsimler arasında ortalama ham protein miktarları arasındaki fark istatistiki olarak önemsiz bulunmuştur (one way ANOVA, P>0,05). Ortalama kuru madde değeri en yüksek kış aylarında (%31,33±0,448), en düşük ise sonbaharda (%30,01±0,280) tespit edilmiştir. Kış mevsiminde tespit edilen kuru madde miktarı aynı zamanda istaitstiki olarak da ilkbahardan yüksektir (P<0,05). Deniz salyangozunun biyokompozisyonuna yem uygunluğu, plankton çeşitliliği, sıcaklık, üreme aktivitelerinin etkisi önemlidir, ayrıca gonat, sindirim bezleri, ayak ve manto kabuk gibi organların biyokompozisyonların bilinmesi de gereklidir. Bu yüzden, gelecekte yapılacak çalışmalarda bu faktörler dikkate alınmalıdır.
