Abstract

AbstractThe present paper reports the abundance and biomass of Dasyatis centroura (Mitchill, 1815), D. marmorata (Steindachner, 1892), D. pastinaca (Linnaeus, 1758), and D. tortonesei Capapé, 1975 at various depth levels and seasons in the Gulf of Antalya, and total length-weight (TL-W), disc length–weight (DL-W) and disc width weight (DW-W) relationship of 391 individuals of D. pastinaca, 21 individuals of D. marmorata, and five individuals of D. centroura, caught in trawling surveys. A total of 116 hauls were carried out, between August 2009 and April 2010 seasonally in the Gulf of Antalya, at six stations and six depth levels (25, 50, 75, 100, 150, 200 m) using a commercial bottom trawl. Dasyatis species were sampled from 65 hauls and the frequency of occurrence was 56.03% for D. pastinaca, 11.21% for D. marmorata, 2.59% for D. centroura and 0.86% for D. tortonesei. The overall mean abundance and biomass was 55.32 ind./km2 and 107.53 kg/km2 for D. pastinaca; 2.54 ind./km2 and 2.56 kg/km2 for D. marmorata, 0.50 ind./km2 and 25.97 kg/km2 for D. centroura and 0.25 ind./km2 and 1.34 kg/km2 for D. tortonesei. The general TL-W, DL-W and DW-W were described by the equations: W = 0.023*TL2.76; W = 0.0999*DL2.74 and W = 0.037*DW2.97 for D. pastinaca; W = 0.002*TL3.23; W = 0.034*DL3.02 and W = 0.0045*DW3.59 for D. marmorata; and W = 0.00001*TL4.04; W = 1.481*DL2.16 and W= 0.141*DW2.59 for D.centroura.
