İzmir Körfezi' nde barbunya (Mullus barbatus, L., 1758) balığının üreme özellikleri

Barbunya (Mute barbatus), izmir Körfezi'nin en önemli demersal balık türlerinden biridir. GSI değerine göre üremenin Mayıs ayında olduğu tespit edilmiştir. Bir dişinin bir defada bıraktığı yumurta miktarının, 1923 ile 13600 adet/birey arasında değiştiği görülmüştür. Sulanmış yumurta yöntemine göre, bir defada bırakılan yumurta miktarı-total boy arasındaki ilişki; F=0,0002L65341, R2= 0,66 ve bir defada bırakılan yumurta miktarı- ağırlık arasındaki ilişki ise, F= 0,3504W-4,8279 R2= 0,715 olarak hesaplanmıştır. Olgunlaşmış yumurta çapları, 0,61-0,72mm ve yağ damlası çapları, 0,19-0,22 mm arasında değişim göstermektedir, ilk üreme boyu, total boy olarak dişiler için 14,2 cm ve erkekler için 12,4 cm olarak hesaplanmıştır.

Reproduction characteristics of red mullet (Mulllus barbatus L., 1758) in İzmir Bay

Reproduction characteristics of red mullet (Mullus barbatus L, 1758) in Izmir Bay. Red mullet (Mullus barbatus L.,1758) is one of the most important demersal fish species on izmir Bay. Reproduction characteristics of this species was studied. Depending on GSI value, reproduction occurs in May. Batch fecundity between 1923 and 13600. By hydrated oocyte method, batch fecundity- total length relation was computed as; F=0,0002L65M1, R2= 0,66 and batch fecundity- weight relation F=0,3504W-4,8279, R2= 0,715. Mature oocyte diameters between 0,61-0,72mm and oil globule diameters between 0,19- 0,22 mm. The length at first maturity was estimated as total length for females 14,2 cm and for male 12,4 cm.
