Abstract

The growth and mortality of brushtooth lizardfish Saurida undosquamis (Richardson, 1848) in Iskenderun Bay (eastern Mediterranean Sea) were investigated based on length frequency data using the FISAT software. Total length of the sampled 4711 fish ranged from 6.0 to 39.0 cm. The von Bertalanffy growth function estimates were L-infinity = 42.00 cm, k = 0.51 year(-1), t(0) = -0.29 years. Total mortality rate (Z) was computed as 1.76 year(-1) and the exploitation ratio was 0.51, indicating that the brushtooth lizardfish stock is on the verge being overfished.
