Description Proučavan je fekunditet traglja, Spicara maena L. uzorkovanog na istočnoj obali srednjeg Jadrana u vrhuncu mrijesta (od 16. rujna do 10. listopada). Ženke, uslijed protoginije, su utvrđene do ukupne dužine od 20,0 cm. Apsolutni fekunditet je kolebao od 42 140 kod drugog godišta do maksimalnih 80 509 u trećem godištu. Srednji je promjer oocita bio od 1,68 do 1,92 mm. Odnos između apsolutnog fekunditeta i ukupne dužine, odnosno ukupne mase, određen je slijedećim eksponencijalnim jednadžbama: Fl = 33,4 TL2.6 (R2 = 0,933) i Fw = 560.2Wt + 15874 (R2 = 0.693). Nije bilo značajne korelacije između veličine oocita i veličina ženki.
We studied the fecundity of Spicara maena L. collected in the eastern central Adriatic Sea at the peak of the spawning period (from 16 September to 10 October). Due to protogyny, females up to
a total length of 20.0 cm were observed. Absolute fecundity varied from a minimum of 42140 eggs for two-year-olds to a maximum of 80509 for three-year-olds. The mean oocyte diameter ranged
1.68-1.92 mm. The relationships between absolute fecundity and total weight and length of the females were best described by the following exponential equations: Fl = 33.4 TL2.6 (r2 = 0.933) and
Fw = 560.2Wt + 15874 (r2 = 0.693). There was no significant correlation between oocyte size and maternal size.
