Change in oceanographic conditions causes structural alterations in marine fish communities, but this effect may go undetected as most monitoring programs until recently mainly have focused on oceanography and commercial species rather than on whole ecosystems. In this paper, the objective is to describe the spatial and temporal changes in the Barents Sea fish community in the period 1992-2004 ...
Responses to over-fishing are very similar. Efforts begin with gear restrictions, area closures and seasonal closures. Entry restrictions, including a license moratorium and a license buyback program, often follow. The results are similar too. Over-fishing and effort increases continue. Common property (not open access) regimes (community development quotas—CDQs), private property regimes (indi...
BACKGROUND Effective yet practical strategies are needed to increase engagement in HIV treatment and prevention services, particularly in high-HIV-prevalence hotspots. We designed a community-based intervention called "Health Scouts" to promote uptake and adherence to HIV services in a highly HIV-prevalent fishing community in Rakai, Uganda. Using a situated Information, Motivation, and Behavio...
On coral reefs, herbivorous fishes consume benthic primary producers and regulate competition between fleshy algae and reef-building corals. Many of these species are also important fishery targets, yet little is known about their global status. Using a large-scale synthesis of peer-reviewed and unpublished data, we examine variability in abundance and biomass of herbivorous reef fishes and exp...
Fish as a ‘bridge’ connecting migrant fishers with the local community: findings from Okinawa, Japan
Migration is part of fishers’ livelihood strategies, and the topic of ‘migration and fisheries’ has gained considerable attention from researchers. Previous works identified negative and positive impacts of migrant fishers on local communities. However, little attention has been given to how social relationships are actually built between migrant fishers and local residents. This paper is based...
Disturbance of the Marine Benthic Habitat by Commercial Fishing: Impacts at the Scale of the Fishery
Commercial fishing is one of the most important human impacts on the marine benthic environment. One such impact is through disturbance to benthic habitats as fishing gear (trawls and dredges) are dragged across the seafloor. While the direct effects of such an impact on benthic communities appear obvious, the magnitude of the effects has been very difficult to evaluate. Experimental fishing-di...
Marine Protected Areas (MPAs) offer a unique opportunity to test the assumption that fishing pressure affects some trophic groups more than others. Removal of larger predators through fishing is often suggested to have positive flow-on effects for some lower trophic groups, in which case protection from fishing should result in suppression of lower trophic groups as predator populations recover...
