Weight-Length Relationships (WLRs) of Scaldback, Arnoglossus kessleri Schmidt, 1915 (Pleuronectiformes: Bothidae), Caught by Beam Trawl in the Southeastern Black Sea (Rize, Turkey)
Abstract
The Scaldback, Arnoglossus kessleri, is an endemic fish to the Mediterranean and Black seas. The present study was conducted to determine the weight-length relationships (WLRs) of this endemic species caught by beam trawl on the Rize province coasts of the southeastern Black Sea, Turkey and to compare the WLRs parameters of A. kessleri from different geographical locality for contributing fisheries management of this fish species in the Black Sea. The WLRs parameters of A. kessleri were showed that A. kessleri exhibited positive allometric (or hyperallometric) growth characteristics for male and combined data (Pauly’ t test, P < 0.05) and isometric growth for female (Pauly’ t test, P > 0.05). The values of coefficient (r) for female, male and combined data of this species are different from zero (P < 0.05), indicated that A. kessleri has higher correlation in the WLRs equations. In addition to this, to compare the estimations calculated from the present study with other studies, log(a) values were plotted against values of slope (b), proved to be consistent with previous studies data for unsexed A. kessleri specimens. This study provides new basic information on the LWRs for A. kessleri populations, in support of sustainable fisheries management of this species and especially of the coastal waters in the Black Sea, Turkey.
