Otolith morphometry and population parameters of red porgy, Pagrus pagrus (Linnaeus, 1758) in Saros Bay (North Aegean Sea)
Abstract
In this study, total length (TL) – total weight (TW) relationship, age, growth, and the morphometric relationships of otolith between otolith length (OL) and otolith weight (OW), total length (TL) and otolith length (OL), total weight (TW) and otolith length (OL), otolith width (OWi) and otolith length (OL) of Pagrus pagrus were investigated in Saros Bay (North Aegean Sea). A total of 100 specimens were measured as minimum TL 9.6 cm, maximum TL 44.4 cm, and minimum TW 17.1 g and maximum TW 1372.5 g. A total of 55 otoliths were measured as minimum OL 0.52 cm, maximum OL 1.17 cm, minimum OW 0.0181 g, and maximum OW 0.1456 g. The relationships between TL and TW, OL and OW, TL and OL, OL and TW, OL and OWi were determined as TW=0.021*TL2.885 (r2=0.98), OW=0.105*OL2.609 (r2=0.929), OL=0.024*TL+0.249 (r2=0.839), TW=0.235*OL0.237 (r2=0.814), and OWi=0.501*OL+0.116 (r2=0.832), respectively. Maximum age was 9 years for P. pagrus and von Bertalanffy growth parameters were estimated as L∞=51.59 cm, K=0.12 year-1 and t0=-1.13 year.
