Turkish Journal of Zoology

This study aims to determine the species belonging to the family Turridae in İzmir Bay, based on specimens collected from 11 stations between 1995 and 1998. As a result of examinations, 15 species are determined in the region. Among these, Mangelia paciniana (Calcara, 1839), Raphitoma echinata (Brocchi, 1814) and Philbertia horrida Monterosato, 1884 are Mediterranean endemic species, and are new records for the Turkish coasts. Other species listed in this study are distributed both in the Mediterranean Sea and the Atlantic Ocean.

Age And Growth Parameters Of Red Bandfish (Cepola Rubescens L., 1766) In İzmir Bay, Murat Kaya, Okan Özaydin, Hüseyi̇n Avni̇ Benli̇

Turkish Journal of Zoology

The age and growth parameters of red bandfish (Cepola rubescens L.,1766) were determined from the specimens collected in İzmir Bay (Aegean Sea) between January 1996 and February 1997. Mean length at age data from otolith readings were used to estimate the growth parameters of the von Bertalanffy equation: for females, L_{\infity}=78.48 cm, K=0.17 y^{-1}, t_o=0.0972 y, W_{\infity}=110.00 g, K=0.10 y^{-1}, to=0.1033 y and for males L_{\infity}= 83.22 cm, K=0.16 y^{-1}, t_o=0.0888 y ; W_{\infity}=129.83, K=0.0818 y^{-1}, to=-0.4117 y. Length-weight relationships was estimated for males and females to be W=0.07723 L^{1.11217} and W=0.029154 L^{1.38434}, respectively. The observed mean total length and …
