Reproductive biology of the flatfish Etropus crossotus (Pleuronectiformes: Paralichthyidae) in the Paranaguá Estuarine Complex, Paraná State, subtropical region of Brazil
Provedor de dados: 83
Autores: Oliveira,Elton Celton de; Favaro,Luís Fernando.
The present work studied the reproduction of the flatfish Etropus crossotus in the Paranaguá Estuarine Complex, Paraná State, subtropical region of Brazil. Monthly collections of biological material occurred from October 2008 to October 2009, at seven sampling sites, through ten-minute otter trawl surveys in the shallow infralittoral areas of the estuary. Temperature, water salinity, photoperiod, and rainfall data were also recorded. Ovarian histology was used to: 1 - describe ovarian development microscopically, 2 - make the quantitative analyses of both sexes more precise. The maturation curve, the frequency of gonadal maturation states and the condition factor verified that the reproductive period occurred from October to January. The frequency of young...

Aspectos reprodutivos de Sphoeroides greeleyi (Gilbert), Pisces, Osteichthyes, Tetraodontidae, da gamboa do Baguaçu, Baia De Paranaguá, Paraná, Brasil

The present study analyses the reproductive aspects of Sphoeroides greeleyi (Gilbert, 1900), such as morphology and histochemistry of carbohydrates in the oogenesis phases, maturity scale, time and type of spawn, sexual rate and first ripened mature size for females. From the monthly captured animais (Nov 1998 to Nov 1999) the morphometric data (entire length and total weight) were extracted and the sex and the gonadal maturity were determined. Some ovaries were prepared for microscopic analysis that charac-terized six phases for the development of the ovarian folheies. Through the carbohydrates analysis the acid carbohydrates could be related to the oogenesis maintenance and the neutral carbohydrates to the beginning of embryonic development. A maturity...

Reprodução do peixe-rei, Atherinella brasiliensis (Quoy &amp;amp; Gaimard) (Atheriniformes, Atherinidae), em uma planície de maré adjacente à gamboa do Baguaçu, Baía de Paranaguá, Paraná, Brasil
Provedor de dados: 104

The present study investigated the reproductive biology of silverside, Atherinella brasiliensis (Quoy &amp;amp; Gaimard, 1825) in a tidal flat of Paranaguá Bay, littoral of Paraná State, Brazil. Fish were captured monthly from November 1998 to October 1999 by the mean of a seine-net. For each individual, total body length, total weight, sex, and gonadal weight were recorded. Gonadal development stages were also defined based on the histological examination of the ovaries and on the visual aspects of the testes. It was defined that the reproductive period of A. brasiliensis extends from June to December, based on he analyses of individual gonadosomatic index (GSI) values distribution in relation to the sampling periods, on the monthly variation of the GSI...
