Estimation of growth, mortality and the exploitation rate of the Scaldfish (Arnoglossus laterna Walbaum, 1792) population from the Yumurtalık (Adana) Bight
Abstract
This study was carried out for the identification of the growth characteristics, mortality rates and the exploitation rate of the scaldfish (Arnoglossus laterna) stock from the Yumurtalık
Bight. von Bertalanffy growth constants for this species were L∞=15.60 cm, K=0.13year-1, t0=-1.54year and W∞=27.64gr, and it was estimated that the highest growth in length and weight for scaldfish were between the age groups Ist to IInd and Vth to VIth respectively. Also, it was estimated that total mortolity was Z=0.5319 and its components were M=0.3619 and F=0.1700. In addition to this, it was found that the exploitation rate on the scaldfish stock inhabited along the Yumurtalık Bight was not enough.
