Some Population Parameters of Morocco dentex, Dentex maroccanus Valenciennes, 1830 in the Northeastern Mediterranean Sea

Abstract

In this study, a total of 95 Dentex maroccanus samples (n♀=37, n♂=58) were examined from the northeastern Mediterranean Sea. The sex ratio was calculated as 0.63:1. The mean total length (TL), fork length (FL), and standard length (SL) were 12.1 ± 0.082 cm, 11.1 ± 0.075 cm, and 10.0 ± 0.068 cm for all samples, respectively. The mean weight (W) was 32.81 ± 0.575 g. The length-length relationships were determined as TL=1.1367SL+0.7136, TL=1.0607FL+0.2804, and FL=1.0631SL+0.494 for all samples, respectively. The total length-weight relationships were determined as W=0.08TL2.409, W=0.1183TL2.246, and W=0.0489TL2.613 and the growth was negative allometric for all individuals, females, and males, respectively. The mean condition factor was calculated as 1.84 for all individuals, 1.78 for females, and 1.88 for males. There are no previous studies about the population parameters of Morocco dentex and the present study gave the first information on the length-weight, length-length relationships, and condition factors of D. maroccanus population inhabiting the northeastern Mediterranean Sea
