Reproductive biology of Diplodus vulgaris ( Teleostei , Sparidae ) in the southern Tunisian waters ( Central Mediterranean )
ACTA ADRIATICA(2013)
摘要
The reproduction of the common-two banded seabream (N=916), Diplodus vulgaris, was studied in the Gulf of Gabes (Tunisia). The length at the first maturity averages 13.64 ± 0.18 cm for males and 13.84 ± 0.17 cm for females. Macroscopic examination of gonads and gonad-somatic index indicated that spawning occurs once a year between November and February with peak activity in November and December. Fecundity estimates ranged from 8 400 to 30 800 oocytes. ISSN: 0001-5113 AADRAY ACTA ADRIAT., 53(3): 437 446, 2012
