Some Population Parameters of The Lessepsian Suez Puffer From Iskenderun Bay, Northeastern Mediterranean, Turkey

In this study the length-weight relationships (LWRs), length-length relationships (LLRs) and relative condition factor were determined for Lagocephalus suezensis captured in the Gulf of Iskenderun, northeastern Mediterranean Sea. Sampling was carried out by commercial bottom trawls using at 24 and 50 meters depths during August and December 2012. The population of Suez puffer fish showed the expected ratio of 1:1. The exponent b values were 2.6764 plus or minus 0.0025 for male and 2.9144 plus or minus 0.0019 for female and 2.7946 plus or minus 0.0014 for sexes combined of L. suezensis. The coefficient of determination (R2) was significant for all individuals. The types of growth for both sexes were negative allometric growth for L. suezensis. The LLRs between the three length measurements (total length, fork length, standard length) were highly correlated (R2 Greater than 0.9527). Relative condition factor (Krel) ranged from 1.165 plus or minus 0.009 (for male) to 1.169 plus or minus 0.009 (for female). This study presented the first reference on LLRs and condition factor for Lessepsian puffer from NE Mediterranean coast of Turkey.
