Some biological aspects of brown comber, Serranus hepatus (L.) (Pisces: Serranidae), in the Sea of Marmara, Turkey

Zeliha Erdoğan, Hatice Torcu Koç

Abstract

Age, growth, gonadosomatic index and condition factor of brown comber, Serranus hepatus (L.) were evaluated from 162 specimens collected in Bandırma Bay, the Sea of Marmara between the years of 2012 and 2013 by the hauls of trawls. Total length ranged between 6.5-11.1 cm, while weight varied between 3.62 and 21.52 g. The length-weight relationship was W=0.0216*L2.84, showing negative allometry. According to otolith readings, samples were determined between 1–5 years. The von Bertalanffy growth parameters were estimated as L∞=12.46cm, k=0.19 yıl-1, to=–4.32, W∞=34.77 g, k=0.09 yıl-1 and to=-1,63. Although brown comber has no economic value for Turkish Seas, it is important in the view of biodiversity.
