1. Intraspecific food resource partitioning in Brazilian silverside Atherinella brasiliensis (Atheriniformes: Atherinopsidae) in a tropical estuary, Brazil
RESUMO Nós investigamos a partição intraespecífica de recursos alimentares do peixe-rei Atherinella brasiliensis em um estuário tropical. Um total de 1.099 estômagos foi analisado, e a dieta foi constituída principalmente de Gastropoda, Larva de Ceratopogonidae, Larva de Decapoda, Calanoida, Cyclopoida, Hymenoptera e Brachyura. A análise de ordenaç�

3. Growth of the silverside Atherinella brasiliensis in a subtropical estuary with some insights concerning the weight-length relationship
ABSTRACT Specimens of Brazilian silverside (Atherinella brasiliensis, n=9672) with a length range of 1.5 to 14.2 cm were captured in the intertidal areas of the Estuarine Complex of Paranaguá, Brazil, between August 2010 and July 2011. The species’ weight-length relationship was represented by the equation W=0.00533 L3.136 with a slightly positive allomet

4. Community structure of metazoan parasites of silverside, Odontesthes bonariensis (Pisces, Atherinopsidae) from Argentina
The helminth communities of silverside, Odontesthes bonariensis (Valenciennes, 1835), from two Argentinean lagoons were studied and compared at component community and infracommunity levels. Nine helminth species were found: five digeneans (Austrodiplostomum cf. mordax, Ascocotyle (Phagicola) cf. diminuta, Ascocotyle sp., Thometrema bonariensis and Saccocoel

5. Growth of the Silverside Atherinella brasiliensis in Tramandaí Estuary, Southern Brazil (Actinopterygii: Atherinopsidae)
O crescimento de Atherinella brasiliensis (Quoy & Gaimard, 1824) foi estudado através de amostras mensais na laguna de Tramandaí, Imbé, Rio Grande do Sul, Brasil. Os animais foram capturados com uma rede de arrasto de praia (picaré) de 15 m de comprimento, 3 m de altura e malha de 5 mm entre nós adjacentes. Relações peso/comprimento e curvas de cresci

6. Improving the production of transgenic fish germlines: in vivo evaluation of mosaicism in zebrafish (Danio rerio) using a green fluorescent protein (GFP) and growth hormone cDNA transgene co-injection strategy
In fish, microinjection is the method most frequently used for gene transfer. However, due to delayed transgene integration this technique almost invariably produces mosaic individuals and if the gene is not integrated into germ cells its transmission to descendants is difficult or impossible. We evaluated the degree of in vivo mosaicism using a strategy whe

7. Dinâmica populacional e Atherinella brasiliensis (Quoy &Gaimard, 1824) da praia de Itamambuca, Ubatuba (SP) / Populacional dynamic of the Atherinella brasiliensis (Quoy &Gaimard, 1824) from Itamambuca beach, Ubatuba (SP)
The present study analyzed the life history and metal levels of Atherinella brasiliensis from Itamambuca beach, Ubatuba (SP). Surveys were conducted monthly, in diurnal and nocturnal periods, between September 2003 and February 2005, in four stations at the beach and one at the Itamambuca river, using beach seine. Individuals showed daily migration into the

8. BIOLOGIA REPRODUTIVA DO PEIXE-REI Odontesthes argentinensis (ATHERINOPSIDAE), DA REGIÃO MARINHA COSTEIRA E REGIÃO ESTUARINA DA LAGOA DOS PATOS.
The silverside Odontesthes argentinensis (Valenciennes, 1835) is distributed in the coastal region of the South Atlantic since the south of Brazil until Argentina (coastal sea population - PMAR) penetrating in the estuaries to which are adapted, being considered a resident estuarine species (estuarine population - PEST). This work had as objective to determi

11. Reprodução do peixe-rei, Atherinella brasiliensis (Quoy & Gaimard) (Atheriniformes, Atherinidae), em uma planície de maré adjacente à gamboa do Baguaçu, Baía de Paranaguá, Paraná, Brasil
The present study investigated the reproductive biology of silverside, Atherinella brasiliensis (Quoy & 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 wer

12. A growth hormone-based phylogenetic analysis of euteleostean fishes including a representative species of the Atheriniformes Order, Odontesthes argentinensis
The GH (growth hormone) cDNA sequence of the marine silverside fish Odontesthes argentinensis was obtained using the RACE protocol (Rapid Amplification of cDNA Ends). The marine silverside GH cDNA sequence is 928 nucleotides long and was found to encode a polypeptide of 204 amino acids, including a signal peptide of 17 amino acids. The 5' and 3' untranslated
