Özet
This study revealed the length-weight relationship, age, growth and mortality parameters, and reproductive biology of thecommon sole, Solea solea in the Sea of Marmara, Turkey. Samplings were conducted with bottom trawl between March2017 and December 2018 at 34 stations. The length-weight relationship was calculated as W=0.0082×TL3.01. Ages wereranged between 1 and 5 years. The von Bertalanffy growth parameters were calculated as L?=34.56 cm, K=0.48 y-1, and t0=-0.01 y. The size at first maturity was 21.9 cm TL. The extended reproduction period was observed (from September to April).The rates of natural mortality (M), total mortality (Z), fishing mortality (F), and exploitation rate (E) were calculated to be0.79, 2.4, 1.61, and 0.67, respectively. The biological reference points were calculated as Fopt=0.395; Flim=0.53 andEopt=0.333, respectively. The length where the maximum yield can be obtained (Lopt) was found as 22.3 cm TL. The resultsshowed that S.solea is under the influence of excessive fishing pressure in the Sea of Marmara.
