Age growth, and sex of golden grey mullet, Liza aurata (Risso, 1810) in homa lagoon (Risso, 1810) in homa lagoon (İzmir bay, Aegean Sea)

Çalışmada, dalyanın üretim sezonu içinde kuzuluklardan avlanmış 342 bireyden faydalanılarak türün; yaş, büyüme ve eşey oranlan saptanmıştır. Örneklerin, 7.5-39.5 cm total boya sahip O-lV'üncü yaştaki bireylerden oluştuğu belirlenmiştir. Populasyon için boy-ağırlık ilişkisi W=0.01 *L293,1^=43.2 cm, K=0.33 yıl"1 ve to=-0.30 yıl olarak, erkek:dişi oranı 1:1.87 ve ilk eşeysel olgunluk yaşı her iki eşey için birinci yaş olarak saptanmıştır.

Homa Dalyanı'nda (İzmir Körfezi, Ege Denizi) Altınbaş Kefal' in Liza aurata( Risso, 1810) yaş, büyüme ve eşey oranı

In this study, age, growth, and sex ratio of 342 golden grey mullets, which were caught in fish traps during fishing season were determined. The samples were between 7.5 and 39.5 cm in length and were between < 1 and 4 years old. The length-weight relationship for this population was calculated as W = 0.01 *L2'93, L^ = 43.2 cm, K = 0.33 yr~1, and t0 = -0.30 yr. The male:female ratio of the population was 1:1.87 and first maturity was at the age of one year for both sexes.
