Popis: This study was performed to assess exploitation, growth characteristics, reproduction, mortality rates and exploitation rate of the Brushtooth lizardfish (Saurida undosquamis), from the Babadillimanı Bight, located in the Western entrance of Mersin Bay. For this purpose, 2757 individuals Brushtooth lizardfish were obtained by monthly samplings between May 1999 and April 2000, and they consisted of 39 % males, 29% females and 32% juveniles. Considering growth characteristics, Length-weight relationship was W = 0.0047xL3.095, and von Bertalanffy growth constants in length and weight were L∞ = 41.57 cm, K = 0.118 year-1, to =-1.895 year and W∞ = 474.59 g, respectively. It was also estimated that total mortality was Z = 0.7664 year 1, and its components were M = 0.4033 year-1, F = 0.3631 year-1. When exploitation rate was taken into account, it was found that the Brushtooth lizardfish was under exploited (E=0.47 year-1) in the Babadillimanı Bight.
Bu çalışma, kuzeydoğu Akdeniz’deki Indo-Pasifik Iskarmozu (Saurida undosquamis Richardson, 1848)’nun yaş, büyüme, üreme ve ölüm oranlarını belirlenmek amacıyla yapılmış olup; Mayıs 1999-Nisan 2000 tarihleri arasında aylık olarak gerçekleştirilen dip trolü örneklemeleri sonucunda elde edilen 2757 adet S. undosquamis incelenmiştir. Boy-Ağırlık ilişkisinin l-1, to = - -1, M=0.4033yıl-1 ve F=0.3631yıl-1 olduğu, stoktan yararlanma düzeyleri dikkate alındığında ise, bölgede hemen hemen optimum düzeyde yararlanıldığı (0.47 yıl-1) belirlenmiştir.
