Rocky reef fish assemblage structure in coastal islands of Southern Brazil
Rocky reef fish assemblage structure in seven coastal islands of Southern Brazil was characterized by underwater visual census (20 m x 2 m transect method 40 m2), average depth of six meters, to obtain density (fish/40 m2) and biomass (grams/40 m2). Fish

How many fish? Comparison of two underwater visual sampling methods for monitoring fish communities [PDF]
Background Underwater visual surveys (UVSs) for monitoring fish communities are preferred over fishing surveys in certain habitats, such as rocky or coral reefs and seagrass beds and are the standard monitoring tool in many cases, especially in protected

Perceptions of trends in Seychelles artisanal trap fisheries: comparing catch monitoring, underwater visual census and fishers' knowledge [PDF]
SUMMARYFisheries scientists and managers are increasingly engaging with fishers’ knowledge (FK) to provide novel information and improve the legitimacy of fisheries governance. Disputes between the perceptions of fishers and scientists can generate conflicts for governance, but can also be a source of new perspectives or understandings.

ABSTRACT Risk management has evolved to analyze risks in a systemic way, integrating local knowledge with the abstract concept of resilience, which is now an imperative for vulnerable and exposed communities. However, existing decision‐support tools are mainly focused on technical‐functional aspects and, although based on rigorous and scientific ...

fishmax: An R package for Bayesian estimation of maximum body size in animals
Abstract Maximum body size is a key trait of an animal species, determining its population dynamics, productivity and interactions with other species and the environment. For fish in particular, the maximum body length or Lmax$$ {L}_{\mathrm{max}} $$ correlates strongly to other life history parameters and is commonly used in ecological models and ...

ABSTRACT Biophysical processes associated with large‐scale nearshore oceanographic upwelling can influence coral reef communities by increasing the delivery of nutrient subsidies and food resources to reefs. However, these processes occur alongside anthropogenic activities that may alter ecological patterns across coral reef ecosystems.
