Abstract

Age, growth, length-weight relationship and reproduction were investigated for striped seabream (Lithognathus mormyrus L., 1758) collected from Beymelek Lagoon (Antalya, Turkey) between February 2006 and January 2007. The ages of striped seabream ranged from 0 to 3 years for males and from 0 to 4 years for females. Their total lengths and weights ranged between 14.4 and 26.4 cm and 42 and 297 g for males and 14.3 and 27.4 cm and 40 and 329 g for females, respectively. The growth parameters of the von Bertalanffy equation were: L\infinity = 28.3 cm, K = 0.456 year-1 and t0 = -1.859 year for males, L\infinity = 28.1 cm, K = 0.466 year-1, and t0 = -1.982 year for females and L\infinity = 31.5 cm, K = 0.319 year-1 and t0 = -2.201 year for all individuals (male, female, and immature). The fitted length-weight relationships of males and females were W = 0.0089×L3.1599 (r2 = 0.9591) and W = 0.0076×L3.2187 (r2 = 0.8982), respectively. Weight increased positive allometrically with the total length for males, while isometrically for females. First sexual maturity length was determined as 17.8 cm for male and 18.5 cm for female striped seabream in Beymelek Lagoon. According to trends of GSI values, it was assumed that the spawning was in April and May.

Özet

Şubat 2006 - Ocak 2007 tarihleri arasında Beymelek Lagünü’nden yakalanan mırmır balıklarının (Lithognathus mormyrus L., 1758) yaş, büyüme, boy-ağırlık ilişkisi ve üremesi incelenmiştir. Mırmır balıklarının yaşları erkekler için 0 ile 3, dişiler için 0 ile 4 arasında değişmiştir. Total boy ve ağırlıkların da erkekler için 14,4-26,4 cm ve 42-297 g, dişiler için 14,3-27,4 cm and 40-329 g arasında değiştiği saptanmıştır. Von Bertalanffy büyüme denkleminin parametreleri erkekler için L∞ = 28,3 cm, K = 0,456 yıl-1 ve t0 = -1,859 yıl, dişiler için L∞ = 28,1 cm, K = 0,466 yıl-1 ve t0 = -1,982 yıl ve tüm bireyler (erkek, dişi ve eşeysel olgunluğa erişmemiş) için L∞ = 31,5 cm, K = 0,319 year-1 and t0 = -2,201 şeklinde bulunmuştur. Boy-ağırlık ilişkisi ise erkek ve dişi bireyler için sırasıyla W = 0,0089×L3,1599 (r2 =0,9591) ve W = 0,0076×L3,2187 (r2 =0,8982) olarak belirlenmiştir. Ağırlığın boy ile erkek bireylerde positive allometrik, dişi bireylerde ise isometric olarak arttığı saptanmıştır. İlk eşeysel olgunluk boyu erkeklerde 17,8 cm, dişilerde 18,5 cm olarak bulunmuştur. Üremenin ise, GSI değerlerinin seyrine göre Nisan ve Mayıs ayında gerçekleştiği tahmin edilmiştir.
