1. Metaplasia in swim bladder epithelium of the endangered annual fish Austrolebias nigrofasciatus (Cyprinodontiformes: Rivulidae) results in inadequate swimming and delayed growth
RESUMO A criação de peixes anuais é frequentemente comprometida pela ocorrência de peixes que não inflam a vesícula gasosa após a eclosão. Estes peixes não têm capacidade de se manter e nadar na coluna d’água e se locomovem no fundo da água, por isso são chamados belly-sliders. Portanto, objetivamos entender os fatores subjacentes à inflaçã

2. Review of the family Rivulidae (Cyprinodontiformes, Aplocheiloidei) and a molecular and morphological phylogeny of the annual fish genus Austrolebias Costa 1998
ABSTRACT The family Rivulidae is the fourth most diverse clade of Neotropical fishes. Together with some genera of the related African family Nothobranchiidae, many rivulids exhibit a characteristic annual life cycle, with diapausing eggs and delayed embryonic development, which allows them to survive in the challenging seasonal ponds that they inhabit. Rivu

3. What are the main local drivers determining richness and fishery yields in tropical coastal fish assemblages?
ABSTRACT Seasonal ecological effects caused by temperature and photoperiod are typically considered minimal in the tropics. Nevertheless, annual climate cycles may still influence the distribution and abundance of tropical species. Here, we investigate whether seasonal patterns of precipitation and wind speed influence the structure of coastal fish assemblag

4. Productive performance and economic evaluation of tilapia stocked in different times of the year
ABSTRACT This study aimed to determine production cycles based on the stocking period and the influence of the cycles on productive performance indices, production costs, and profitability. The present study was carried out on a fish farm located in Palmital - SP, Brazil, which consists of 2706 m3 of net cages with an annual production of 400 tons of tilapia

5. Parasites of two coexisting invasive sailfin catfishes (Siluriformes: Loricariidae) in a tropical region of Mexico
ABSTRACT Currently many species of Amazon sailfin catfishes (Loricariidae) have been introduced to wild environments outside their native range. There is, however, little knowledge about their role as vectors of parasites that can infect native fish or even humans through its consumption. The aim of the present study was to determine the parasitic fauna of t

6. The reproductive biology of Pinguipes brasilianus Cuvier, 1829 (Osteichthyes: Pinguipedidae) in temperate rocky reefs of Argentina
ABSTRACT Pinguipes brasilianus is a conspicuous and abundant rocky-reef fish inhabiting the Northern Patagonian gulfs of Argentina, Southwest Atlantic. This study describes its reproductive biology in this region. We made macroscopic and histological descriptions of the testis and ovary development, analyzed the evolution of the gonadosomatic index (GSI) in

7. Sex determination in annual fishes: searching for the master sex-determining gene in Austrolebias charrua (Cyprinodontiformes, Rivulidae)
Evolution of sex determination and differentiation in fishes involves a broad range of sex strategies (hermaphroditism, gonochorism, unisexuality, environmental and genetic sex determination). Annual fishes inhabit temporary ponds that dry out during the dry season when adults die. The embryos exhibit an atypical developmental pattern and remain buried in th

8. Ecophysiological responses to the effect of annual management on an endemic viviparous fish in central plateau of Mexico
Studies on the biological aspects of fish typically focus on species that currently have commercial value, causing species that lack such market value to be ignored. This is the case of several freshwater fish, specifically of several members of the Goodeidae family. In the State of Querétaro there are several species of this family characterized for being

9. Spectrolebias brousseaui (Cyprinodontiformes: Rivulidae: Cynolebiatinae), a new annual fish from the upper río Mamoré basin, Bolivia
Spectrolebias brousseaui é descrita de uma poça temporária localizada na região superior da bacia do río Mamoré, departamento de Santa Cruz, Bolívia. A espécie nova distingue-se de todos os congêneres pelo padrão de cor azul escuro nos dois terços posteriores do corpo com pontos azuis claros iridescentes alinhados verticalmente em machos. Spectrol

10. Growth of Critically Endangered annual fish Austrolebias wolterstorffi (Cyprinodontiformes: Rivulidae) at different temperatures
Devido à importância do conhecimento da biologia das espécies ameaçadas de extinção para o planejamento de ações de conservação e manejo, o objetivo deste estudo foi investigar a influência da temperatura sobre o crescimento de Austrolebias wolterstorffi (Ahl, 1924). Para verificar a influência da temperatura no crescimento da espécie, as temper

11. Idade, crescimento e biologia reprodutiva da Raia-viola Rhinobatos percellens (Walbaum, 1792) capturada pelo arrasto de praia em Caiçara do Norte/RN.
Caiçara do Norte (05 04S and 36 03W) is considered one of the biggest marine fish producer in the Rio Grande do Norte State where beach seine captures shrimp. Rhinobatos percellens is the third most abundant species found in the by-catch. From June 2003 to May 2011, 714 beach seine hauls were closely monitored with the objective of analyzing the population

12. Spatial and temporal structure of fish assemblages in a hyperhaline coastal system: Ría Lagartos, Mexico
The spatial and temporal fish species assemblages were analyzed throughout two annual cycles (2004-2005 and 2007-2008) in the Ría Lagartos Lagoon system, Mexico, via non-parametric multivariate analyses. We compared density and biomass of fish species among five habitat types defined by combinations of structure and environmental characteristics (hyperhalin
