Introduction: Video techniques are used worldwide to study marine communities. As elsewhere, the use of remote underwater videos has recently increased in Brazil and there is a need for information about their advantages, disadvantages, reliability tropical habitats. Objective: To evaluate baited video stations (BRUVS) fish diversity research habitat. Methods: We record fishes relationship with...

In many marine ecosystems small pelagic fish exert a crucial role in controlling the dynamics of community, mainly due to their high biomass at intermediate levels food web. These use coastal as nursery areas, but also forage and avoid predation or competition. We studied spatial, seasonal, lunar diel variations community from protected area Bijagós Archipelago, Guinea-Bissau. Fish were sampled...

Os estuários são habitats favoráveis à ocupação por diversas espécies de peixes em virtude da disponibilidade abrigo e alimentação. Entre as ferramentas gestão recursos pesqueiros, os estudos baseados tamanho dos espécimes úteis para a melhor compreensão estrutura das comunidades estuarinas podem ser associados aos aspectos reprodutivos seletividade aparelhos captura aplicáveis mitigação efeito...

Allis shad Alosa alosa hatches and develops in freshwater before migrating to the sea during its first months of life. Some field research works dedicated diet species put forward that young stages allis feed mainly on zooplankton, being opportunistic euryphagous; their would diversify through ontogeny relation growth. However, these assumptions have never been confronted availability prey, exa...
