An economically important species of Citharus linguatula was investigated in the Sea of Marmara (Eastern Mediterranean, Turkey). Length-weight relationships, growth parameters, reproductive time, and first sexual maturity length of the species were determined. A total of 236 individuals were analyzed, total length and weight varied from 7.5 to 26.5 cm TL (17.11±3.62 cm) and 2.67 to 180.81 g (44.07±1.84 g), respectively. The length-weight relationship was calculated as W=0.0047*TL3.17 in total. The growth type was positive allometry for both sexes. Total individuals were ranged in age between 1 and 4. According to sexes, von Bertalanffy growth parameters were calculated as L∞=23.44 cm, K=0.74 per year, and t0=-0.09 year for females and L∞=20.75 cm, K=0.56 per year, and t0=-1.14 year for males. The size at first maturity was 17.6 cm TL for males, and 16.7 cm TL for females. When sexual maturity, K, and GSI values were evaluated together, the reproduction period of C. linguatula was determined between September and December. |
