Reprodução de Stellifer rastrifer (Jordan) (Teleostei, Sciaenidae) na Baía de Guaratuba, Paraná, Brasil
Provedor de dados: 104
Autores: Chaves,Paulo de Tarso da Cunha; Vendel,Ana Lúcia.
A total of 1312 individuais of S. rastrifer were sampled from March 1994 to September 1996 at the Guaratuba Bay, Southern Brazilian coast. This species is a permanently inhabitant of the mangrove area throughout the year. The weight/length relationship of the species in the region is "In TW =-12,35 + 3,22 In TL", and the individuais may reach 172mm of total length. The analyses of gonadal morphology and gonadossomatic index indicate that S. rastrifer is a multiple spawner species, that reproduces at the mangrove area during a long period of the year. The reproductive activity is more intense during the winter and mainly the spring, when the value of Condition Factor declines and empty folheies are found in the ovaries.

Feeding habits of Stellifer rastrifer (Perciformes, Sciaenidae) at Guaratuba mangrove, Parana, Brazil
Provedor de dados: 52
Autores: Chaves,Paulo de Tarso C.; Vendel,Ana Lúcia.
Feeding habits of Stellifer rastrifer (Perciformes, Sciaenidae) at Guaratuba mangrove, Parana, Brazil, were studied from February 1996 to February 1997. It was observed that its diet was based on invertebrates, mainly Decapoda non-Brachyura and Polychaeta. In a smaller proportion there were plants, Copepoda, Gammaridea and Mollusca. The level of contribution of each food item changed according to the season and the individual size. Such plasticity in feeding behaviour was similar to that described to some fish populations from other estuaries, and could be an indicator of the high level of instability presented by this kind of ecosystem.
