Çardak Lagünü’nde pinter ile avlanan yeşil yengeç, Carcinus aestuarii’nin Nardo, 1847 birim çabadaki av miktarı

Çardak Lagünü’nde (Çanakkale Boğazı) yapılan bu çalışmanın amacı pinterle avlanan Yeşil Yengeç, Carcinus aestuarii ’in aylık birim çabadaki av miktarını (BÇAM) belirlemektir. Bu çalışmada yengeç örnekleri Nisan 2015-Mart 2016 arasında pinter aracılığı ile aylık olarak 6 farklı istasyondan toplanmıştır. Çalışma sonucunda toplam 686 dişi, 1755 erkek ve 17 immature birey toplamda 2458 yengeç bireyi örneklenmiştir. En yüksek av verimi Ekim ayında (12.74 birey/gün), en düşük av verimi ise Şubat ayında (2.43 birey/gün) elde edilmiştir. En yüksek BÇAM değeri (10.02 birey/gün) 1. Istasyon için, en düşük (7.02 birey/gün) 6. istasyon için hesaplanmıştır.

Catch per unit effort (CPUE) of green crab, Carcinus aestuarii Nardo, 1847 captured by fyke-nets in Çardak Lagoon

The aim of this study is to determine the catch per unit effort (CPUE) of Green Crab, Carcinus aestuarii captured monthly by fyke-nets in Çardak Lagoon (Çanakkale Strait). In the study, the crabs individuals were sampled by means of fyke-nets at 6 different stations between April 2015 and March 2016. A total of 2458 individuals (686 female, 1755 male and 17 juvenile) were captured. The highest number of catch per unit effort (CPUE) value in October, and the lowest value was in February. The CPUE value was recorded from the highest station number 1 and calculated from the lowest station 6.
