The object of the present work is to supply basic information about the reproductive biology of this species. Samples were collected in Cádiz Bay between February 1999 and March 2000. A total of 901 specimens (440 females and 461 males) were examined. Sex ratio did not differ from the theoretical 1:1, except in May 1999, and February 2000. Minimum size at maturity was 191 mm total length for females and 160 mm total length for males. Approximately 50 % of the population matured at 262 mm for females and 302 mm for males. The spawning season extends from March to August, with a peak in May-June. Fecundity ranged from 227 to 1233 eggs/female, and was related to body length and weight. Length-weight relationship for the sexes differed, and showed positive allometry. The condition factor showed a minimum in the spawning season, which is interpreted as the result of mobilization of somatic energy reserves needed for reproductive development, and/or the use of reserves stored in the body as a source of energy in spawned fish, influenced by reduced feeding during this period.This study received support from the Instituto de Ciencias Marinas de Andalucía - Consejo Superior de Investigaciones Científicas, Spain.Peer reviewedCSIC - Instituto de Ciencias del Mar (ICM)200820082001info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501317025 bytesapplication/pdfhttp://hdl.handle.net/10261/5394reponame:DIGITAL.CSIC.
