14430

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.
