摘要Objective: To determine the fecundity of Boops boops (B. boops) from Aegean Sea coast of Turkey. Methods: A total of 470 specimens of B. boops were collected monthly from November in 2008 to October of 2009 in Izmir Bay (central Aegean Sea). Total length and total weight of each fish were measured and the maturity stages of gonads were determined. About 30 mature ovariums were taken to determine fecundity and oocysts were counted by using gravimetric method. Results: About 210 were females (44.7%) and 226 males (48.1%) while 34 (7.2%) were hermafrodite in terms of sexuality with sex ratio (female: male) of 0.93:1.00. The fecundity of the bogue was assessed by the gravimetric method with 30 ovaries from females between the total length of 19.6 and 27.6 cm [(mean: 23.5 ± 2.1) cm]. Estimates of total fecundity varied between 33072 and 66123 oocytes (mean: 49008 ± 8826) and fecundity–total length, fecundity–weight relationships were expressed as :F = 8207.6e0.075TL, F = 30297e0.003TW respectively. Conclusions: The results of the study will contribute to the reproductive biology of B. boops and will be useful for management of fisheries.
