Effects of trap fishing on reef fish communities
Aquatic Conservation: Marine and Freshwater Ecosystems, 2006Abstract Trap fishing is widespread on coral reefs but the sustainability of this practice is causing concern because it is efficient and unselective. The effects of trap fishing were investigated by comparing fish assemblages among six Caribbean islands subject to different trapping pressures.

Abstract There is a remarkable benthic fish community in deep water in Lake Tanganyika that is rich in endemic species and genetically diverse. Its lower limit is determined by oxygen concentration, some species ranging down to about 200 m depth at the south of the lake where the oxygenated layer is deepest.

Historical Fishing Communities
2016Community-building is one tool of human resilience to overcome the challenges of a hostile environment such as the marine. The chapter provides an overview of how the concept of community has been deployed in historical and social anthropology studies of maritime communities since the 1920s.

Nature Climate Change, 2019
With climate change, marine species are on the move and changing in abundance. Now, research shows that the ecological impacts of climate change will differentially affect fishing communities, even within the same region.

Visual Communication in Fishes
1980The intensity and spectral distribution of the light encountered by an animal species set reasonably broad operational limits for the efficient generation and reception of visual signals. This phenomenon is of special importance to fishes because aquatic environments cause profound changes in the nature of light that penetrates to any depth (Blaxter ...

Fishes, the most abundant and diverse group among all vertebrates, exploit the largest number of communication channels. These two volumes explore how fishes use hearing and vision, as well as the vibrational, electric and chemical modalities in their interactions with one another.

Fishing communities: the course of the fishing life
2018Social contexts inevitably influence entry into the occupation and how fishing lives are shaped by the unfolding of non-fishing identities. Temporal perspectives can help us understand what it means to be a fisher – including the importance of social contexts for entering the occupation and how non-fishing identities shape the unfolding of fishing ...

Gymnotiform fish: an important component of Amazonian fioodplain fish communities
Journal of Fish Biology, 1996Estimates of the density, biomass and species diversity of fish from floating meadow and flooded forest habitats suggest that gymnotiform fish constitute an important component of Amazonian flood plain fish faunas. Electric eels, Electrophorus electricus are unexpectedly abundant within Varzea forest.
