Resumo
A survey performed in the Guaratuba Bay (25º52'S; 48º39'W) and the adjacent marine area has provided additional data about the habits of the croaker in the southern coast of Brazil. A dynamic pattern of movements along the marine and estuarine waters was observed, but it does not indicate spawning activity in the study area. During autumn/winter, pre-adults and adults use the marine waters. In spring/summer, following gonadal maturation,the individuals leave this area and probably move to deeper waters, where they spawn. Until the end of summer, the estuary is then occupied by juveniles coming from the marine spawning area. In autumn/winter, these juveniles and the new pre-adults move to the marine zone adjacent to the bay and begin gonadal maturation. It is suggested that the Guaratuba Bay and the adjacent marine area constitute an important site for growth and recruitment of the early lifestages of M. furnieri and initial stages of reproductive activity.

ABSTRACT
A survey performed in the Guaratuba Bay (25º52'S; 48º39'W) and the adjacent marine area has provided additional data about the habits of the croaker in the southern coast of Brazil. A dynamic pattern of movements along the marine and estuarine waters was observed, but it does not indicate spawning activity in the study area. During autumn/winter, pre-adults and adults use the marine waters. In spring/summer, following gonadal maturation,the individuals leave this area and probably move to deeper waters, where they spawn. Until the end of summer, the estuary is then occupied by juveniles coming from the marine spawning area. In autumn/winter, these juveniles and the new pre-adults move to the marine zone adjacent to the bay and begin gonadal maturation. It is suggested that the Guaratuba Bay and the adjacent marine area constitute an important site for growth and recruitment of the early lifestages of M. furnieri and initial stages of reproductive activity.
