Abstract
    A reproductive study was conducted on 305 individuals of common pandora Pagellus erythrinus, from Mazarrón Bay (Murcia, southeast coast of Spain), providing information for a more adequate interpretation of the gonadosomatic index in this species and its relationship with the stage of maturity of the fish. In terms of the other Mediterranean Sparidae, the GSI values obtained rank in the middle of the scale, being 3.9 ± 1.4% (X ± SD) in spawning females, and 2.0 ± 0.9% in mature males. The GSI of primary males was lower (0.3 ± 0.8), suggesting that there is no sperm competition in this species. Reproductive season in the study area falls within the period between early April and middle July, although the ovotestes may retain some activity until the end of September.
