Abstract

Thisstudy aims to calculate the age, growth, and mortality rate of commerciallyimportant fish species, namely Engraulis encrasicolus, Trachurus mediterraneus,Sprattus sprattus, Merlangius merlangus, and Mullus barbatus, in the southeasternBlack Sea between 2008 and 2011. These species are commercially important forTurkish and other riparian country fisheries. The samplings were carried outusing bottom trawls, purse seines and various gillnets. Length-weight,age-length, the Von Bertalanffy equation, total mortality rate (Z), naturalmortality rate (M), fishing mortality rate (F), and exploitation rate (E) wereestimated for each species to use in further population analyses and stockassessments research. Additionally, the results of this study were evaluatedconsidering the “Task Group 3 Report-Commercially Exploited Fish andShellfish” in the Marine Strategy Framework Directive (MSFD)published by the European Commission (2008/56/EC).
