- Abstract
This study reports the batch fecundity (BF) and oocyte diameters of Belone belone from the Aegean Sea (Izmir and Candarli Bays). A total of 51 female specimens of garfish were collected from January to December 2003. Oocyte diameters (n = 12140) of B. belone ranged from 0.063 to 3.5 mm, concentrating between 0.063 and 1.5 mm. The fish weight - BF relationships according to both hydrated oocyte and oocyte size frequency methods were BF = - 0.3794 W + 192.22 (R² = 0.037) and BF = 5.165 W - 55.21 (R² = 0.218), respectively. Mean oocyte numbers in the ovaries were 4144 ± 604 with varied from 662 to 15962. Maximum BF was 2130 (mean: 670 ± 97) in hydrated oocytes, and 8189 (mean: 1667 ± 559) in large oocytes. There was no linear relationship between BF and fish weight according to determination coefficients.
