Çanakkale Boğazı’ndaki Eriphia verrucosa (Forskål, 1775)’nın (pavurya yengeci) boy-ağırlık ilişkisi

Bu çalışma, Çanakkale Boğazı’nda Eriphia verrucosa (Forskål, 1775)’nın (pavurya yengeci) boy-ağırlık ilişkisinin belirlenmesi amacıyla Nisan 2016 - Mart 2017 tarihleri arasında gerçekleştirilmiştir. Çalışmada, aylık olarak serbest dalış yöntemi ile 239 adet dişi (%39,97) ve 359 adet erkek (%60,03) olmak üzere toplam 598 adet birey örneklenmiştir. Bireylerin karapaks genişliği (CW) tüm, erkek ve dişi bireyler için sırasıyla; CWort. 55,03±0,52mm, 56,55±0,75mm ve 52,76±0,63mm olarak hesaplanmıştır. Bireylerin ortalama ağırlıkları (W) ise erkek ve dişiler için sırası ile 90,48±03,37g ve 62,44±02,16g olarak ölçülmüştür. Pavurya yengeçlerinin CW-W ilişkisi, tüm bireyler için W=0,0003CW3,1083 (R²=0,9158), erkekler için W=0,0002 CW3,163 (R²=0,9223) ve dişiler için W=0,0001CW2,6995 (R²=0,8427) olarak hesaplanmıştır. Hesaplanan b değerine göre tüm ve erkek bireyde pozitif allometri, dişi bireylerde ise negatif allometri tespit edilmiştir.

Length-weight relationship of Eriphia verrucosa (Forskål, 1775) (warty crab) in Çanakkale Strait

This study was carried out between April 2016 and March 2017 in order to determine length-weight relationship of Eriphia verrucosa (Forskål, 1775) in Çanakkale Strait. In the study, 598 individuals were sampled by using skin diving techniques as 239 female (39.97%) and 359 male (60.03%). The carapace width (CW) of the all individuals, males and females was calculated as 55.03±0.52mm, 56.55±0.75mm and 52.76 ± 0.63mm, respectively. The mean weights of the individuals (W) were measured as 90.48 ± 03.37g and 62.44 ± 02.16g respectively for male and female. Relationship between CW and W of warty crab individuals were expressed as W=0.0003CW3.1083 (R²=0.9158) for all individuals, W=0.0002CW3.163 (R²=0.9223) for male and W=0.0001CW2.6995 (R²=0.8427) for females. According to the calculated b value, positive allometry was determined for all individuals and males, negative allometry was determined for female individuals.
