Abstract

In this study, some biological characteristics of a total of 173 Mediterranean toothcarp (Aphanius fasciatus) specimens caught from Gulbahçe bay (İzmir bay) were investigated. Female: male ratio was 1:0.12. Total length of the specimens varied between 13.5 and 63.9 mm. The length-weigth relationship equation was found as W=3.645*10-6 L3.40. Egg diameter and oil globule diameter were ranged from 1.00 to 2.25 mm and from 0.2 to 0.6 mm, respectively. Mature egg number and total egg numbers also varied from 100 to 263 eggs and from 498 to 1262 eggs, respectively.
