Weight and length relationships (WLRs) and meat yield of brown garden snail, Helix aspersum (Müller, 1774) and Turkish snail, Helix lucorum Linnaeus, 1758 (Mollusca: Gastropoda: Helicidae) in the Sinop province, Turkey

Abstract

The present work carried out on the length – weight relationship of two commercially important mollusks Helix aspersa and Helix lucorum were analyzed from Sinop province in the Central Black Sea region climate, Turkey. Totally 86 specimens of H. aspersa and 67 specimens of H. lucorum were collected for this study in 5 April 2018. Parameters of the shell length and weight (W) relationship by using the formula W = aLb . The weight – shell height, weight – shell width and shell height - shell width results suggested that two helix species (H. aspersa and H. lucorum) showed negative growth characteristics (b<3, P<0.05). The shell height and shell width of H. lucorum was significantly (P<0.05) greater than the mean shell height and shell width of H. aspersa. The mean meat yield of H. lucorum was significantly (t-test, P<0.001) lower than the mean meat yield of H. aspersa. The present study can be use for future researches for cooperation to their results.
