Length-weight relationship and condition of Arnoglossus kessleri Schmidt, 1915 in Iskenderun Bay (Eastern Mediterranean, Turkey)

Length weight relationship (LWR) studies have an important role in estimating population biomass, determining growth rate and stock status of fishes. In this study a total of 133 scaldback, Arnoglossus kessleri Schmidt, 1915 were caught in Iskenderun Bay between September 2014 and May 2015 using a commercial bottom trawler. As a result, the estimates for b parameter of the LWR ranged between and 2.97, 2.68 and 2.74 for males, females and both sexes, respectively. Fulton’s condition (KF) factor values also revealed significant variations (p
