Abstract: Age, growth, length-weight relationship and reproduction were in<strong>ve</strong>stigated for<br />
striped seabream (Lithognathus mormyrus L., 1758) collected from Beymelek Lagoon<br />
(Antalya, Turkey) between February 2006 and January 2007. The ages of striped seabream<br />
ranged from 0 to 3 years for males and from 0 to 4 years for females. Their total lengths and<br />
weights ranged between 14.4 and 26.4 cm and 42 and 297 g for males and 14.3 and 27.4 cm<br />
and 40 and 329 g for females, respecti<strong>ve</strong>ly. The growth parameters of the von Bertalanffy<br />
equation were: L-infinity = 28.3 cm, K = 0.456 year(-1) and t(0) = -1.859 year for males, L-<br />
infinity = 28.1 cm, K = 0.466 year(-1), and t(0) = -1.982 year for females and L-infinity = 31.5<br />
cm, K = 0.319 year(-1) and t(0) = -2.201 year for all individuals (male, female, and immature).<br />
The fitted length-weight relationships of males and females were W = 0.0089 x L-3.1599 (r(2)<br />
= 0.9591) and W = 0.0076 x L-3.2187 (r(2) = 0.8982), respecti<strong>ve</strong>ly. Weight increased positi<strong>ve</strong><br />
allometrically with the total length for males, while isometrically for females. First sexual<br />
maturity length was determined as 17.8 cm for male and 18.5 cm for female striped seabream<br />
in Beymelek Lagoon. According to trends of GSI values, it was assumed that the spawning was<br />
in April and May.<br />

Abstract:The study aims to in<strong>ve</strong>stigate some reproducti<strong>ve</strong> properties of bullet tuna (Auxis<br />
rochei) in Turkish waters. A total of 216 bullet tunas, 110 males (50.93%) and 106 females<br />
(49.07%), from the Turkish Mediterranean coasts were sampled monthly between December<br />
2008 and December 2009. The sex ratio was 1:1.04. A total of 106 ovaries were obtained from<br />
the females, and these ovaries were histologically examined to determine the reproducti<strong>ve</strong><br />
conditions and de<strong>ve</strong>lopmental stages of oocytes. The gonado-somatic index (GSI) values<br />
calculated for females indicated that spawning generally occurred between May and<br />
September. The most intensi<strong>ve</strong> spawning period was obser<strong>ve</strong>d between June and August. A<br />
total of 40 females collected between May and September were sexually mature.<br />
