Ocak-Şubat 2011 ve Eylül 2012 tarihleri arasında toplam 24 trol çekimi yapılmıştır. 800 gözlü kesimli dip trol ağından kaçan kırma mercan (Pagellus erythrinus) bireylerini yakalamak için örtü kullanılmıştır. 40 mm kare, 44 ve 50 mm rombik gözlü trol torbalarından kaçan bireylerin ölüm oranları 7 gün boyunca yapılan gözlemler ile tespit edilmiştir. Ayrıca su sıcaklığının kırma mercan ölümleri üzerine etkisi de incelenmiştir. Kırma mercan’ın ölüm oranları düşük bulunmuştur (<%5). Kış ve yaz mevsimleri için deneme ve kontrol gruplarında saptanan ortalama ölüm oranlarında istatistiksel olarak önemli bir fark bulunmamıştır (p>0,05). Her iki mevsim için de ağ göz boyutu ve şekli istatistiksel olarak önemli bir faktör değildir (p>0,01).

In total, 24 replicate hauls were conducted on January-February in 2011 and September in 2012. A tailored bottom trawl with 800 meshes around the mouth was used with covers to retain individuals of common pandora (Pagellus erythrinus). Mortality of fish escaping through 40 mm square, 44 and 50 mm diamond mesh codends was investigated by collecting and monitoring the escapees from the codend covers for 7 days. We also observed possible water temperature effect in the escape mortality of common pandora. The escape mortality of common pandora was negligible (<5%). No significant was demonstrated difference in the average mortality for all test codends and controls between the winter and the summer (p>0.05). Mesh size and shape was not a significant factor (p>0.01) for the both seasons.
