Özet
Length-Weight Relationships, Condition Indexes and Meat Yields of Rapa Whelks (Rapana venosa Valenciennes, 1846) in Yakakent (the southern Black Sea) were investigated. This study was to determine the length-weight relationships, condition indexes and meat yields of Rapana venosa in Yakakent (Samsun, Black Sea). For this aim, 431 rapa whelk specimens were sampled at monthly intervals between December 2014 and November 2015. The total length and weight of the specimens ranged from 43.52 to 109.52mm and from 15.42 to 234.53g, 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 for rapa whelks. The condition indexes varied between 2.58-40.43 with a mean 15.74 +/- 0.26. The highest mean condition index (24.52) was recorded in January 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 in September (23.30%).
