Age, Growth and Mortality of Rock Gurnard (Trigloporus lastoviza (Bonnaterre, 1788)) (Osteichthyes:Triglidae) in İzmir Bay

Abstract

In this study, age, growth and mortality of the rock gurnard (Trigloporus lastoviza) was investigated in İzmir Bay (Aegean Sea) between January and December 2005. The fork lengths of females were ranged from 11.9 cm to 19.8 cm, and that of males from 8.2 cm to 18.2 cm. Sex ratio was 1:1.07 (female: male). The observed maximum age was 6 for females and 5 for males by otolith readings. The length-weight relationships were estimated as W=0.0116*FL3.032 (r=0.985); W=0.0136*FL2.971 (r=0.979) and W=0.0117*FL3.030 (r=0.984) and the von Bertalanffy growth equations for length were found as; Lt=26.80 (1-e-0.152 (t-2.822)), Lt=19.59 (1-e-0.361 (t-1.370)), Lt=23.28 (1-e-0.235 (t-1.887)) for females, males and sex combined, respectively. The growth performance index value (Φ) was calculated as 2.105 for all specimens. Total, natural and fisheries mortalities were estimated as 1.25, 0.62 and 0.63 year-1respectively
