Özet
Bu çalismada, Yakakentbölgesindeki (Samsun, Karadeniz) deniz salyangozlarinin boy-agirlik iliskileri,kondisyon indeksleri ve et verimleri tespit edilmistir. Bu amaçla, Aralik2014-Kasim 2015 tarihleri arasinda aylik periyotlarla 431adet deniz salyangozuörneklenmistir. Toplam boy ve agirlik degerleri sirasiyla 43,52-109,52mm ve 15,42-234,53garasinda degisim göstermistir. Boy-agirlik iliskisi denklemi W=0,0007 L2,7287(r2=0,91) olarak hesaplanmistir. Deniz salyangozlari negatif allometrik birbüyüme göstermistir (t=6,4432; P <0,05). Kondisyon indeks degerleri 2,58-40,43araliginda ve ortalama 15,74±0,26 olarak bulunmustur. En yüksek kondisyonindeks degerleri Ocak ayinda (24,52), en düsük ise Temmuz ayinda (11,17) belirlenmistir.Et verimi oranlari %9,8-%46,27 araliginda, ortalama 29,32±0,29, en yüksek Ocakayi (%36,45), en düsük Eylül ayi (%23,30) olarak tespit edilmistir.
Length-WeightRelationships, Condition Indexes and Meat Yields of Rapa Whelks (Rapana venosa Valenciennes, 1846) inYakakent (the southern Black Sea) were investigated. This studywas to determine the length-weight relationships, condition indexes and meatyields of Rapana venosa in Yakakent(Samsun, Black Sea). For this aim, 431 rapa whelk specimens were sampled atmonthly intervals between December 2014 and November 2015. The total length andweight of the specimens ranged from 43.52 to 109.52mm and from 15.42 to234.53g, respectively. The length-weight equation calculated as W=0.0007 L2.7287(r2 =0.91). Negative allometric growth (t = 6.4432, P<0.05) was observed forrapa whelks. The condition indexes varied between 2.58-40.43 with amean 15.74±0.26. The highest mean condition index (24.52) was recorded inJanuary and the lowest (11.17) in July. Meat yields ranged from 9.08% to 46.27%with a mean 29.32±0.29, the highest in January (36.45%) and the lowest inSeptember (23.30%).
