Mixed‐Species Fish Shoals: Any Port in a Storm?
ABSTRACT Mixed‐species fish shoals are common, and form for a variety of reasons. We suggest that short term mixed‐species shoals, that persist for minutes or hours, might form because lone individuals (or small groups) of one species might benefit from joining larger groups of heterospecifics to reduce predation risk.

Assessing Fish Community Structure and Diversity Across Environmental Gradients in a Tropical Bay
ABSTRACT Understanding the relationship between species distribution and the environment across spatial gradients is crucial for biodiversity evaluation. We surveyed fish populations in a tropical bay, covering a spatial gradient from the outer zone with favorable marine conditions to the inner zone affected by human activities.

Length–weight relationship (LWR) and its parameters can be used for the development of models for the rational exploitation of fishery resources. In this study, we estimated the parameters of the LWRs and length–length relationships (LLRs) of 12 fish species caught incidentally by the artisanal whiteleg shrimp fishery in the Biosphere Reserve Marismas ...
