Atoll-scale patterns in coral reef community structure: Human signatures on Ulithi Atoll, Micronesia
The dynamic relationship between reefs and the people who utilize them at a subsistence level is poorly understood. This paper characterizes atoll-scale patterns in shallow coral reef habitat and fish community structure, and correlates these with environmental characteristics and anthropogenic factors, critical to conservation efforts for the reefs and the people who depend on them. Hierarchic...
We report the complete genome sequence of Ebola virus from a health worker linked to a cluster of cases occurring in the fishing community of Aberdeen, Sierra Leone (February 2015), which were characterized by unusually severe presentation. The sequence, clustering in the SL subclade 3.2.4, harbors mutations potentially relevant for pathogenesis.
agunmukha river is an important water body having plentiful aquatic resources. the fisheries communities in the river are familiar with a diverse range of fishing gear and crafts to catch fish. therefore, the objectives of the present study were to explore fishing gear and fishing crafts, catch composition of the respective gearand identification of fish biodiversity of agunmukha river. a step ...
Fishing is a potent ecological force. In Lake Victoria, East Africa, Nile perch, Lates niloticus contributes to a multi-million dollar fishing industry but is threatened by over-exploitation. We quantified spatial and temporal trends in the distribution, diet and size of Nile perch in Lake Nabugabo, Uganda, a satellite of Lake Victoria. From 1995 to 2007, we detected a decline in catch per unit...
This paper explores the tensions, issues and problems being experienced by one small fishing community off Canada’s east coast, as it confronts the challenges of a rapidly growing aquaculture industry. It examines the significance for the community of changing property regimes, directly related to a government policy, proclaimed in October 2000, that is transforming ownership patterns in the in...
Effects of Marine Reserves versus Nursery Habitat Availability on Structure of Reef Fish Communities
No-take marine fishery reserves sustain commercial stocks by acting as buffers against overexploitation and enhancing fishery catches in adjacent areas through spillover. Likewise, nursery habitats such as mangroves enhance populations of some species in adjacent habitats. However, there is lack of understanding of the magnitude of stock enhancement and the effects on community structure when b...
Identifying the various drivers of marine ecosystem regime shifts and disentangling their respective influence are critical tasks for understanding biodiversity dynamics and properly managing exploited living resources such as marine fish communities. Unfortunately, the mechanisms and forcing factors underlying regime shifts in marine fish communities are still largely unknown although climate ...
Subsistence (or food) fisheries are under-studied, and the interaction between subsistence and commercial fisheries have not been studied systematically. Addressing this gap is the main contribution of the present paper, which focuses on how to deal with the challenge of overlapping commercial and subsistence fisheries. The study was conducted in Norway House Cree Nation, with qualitative data ...
One type of regulation that has recently started to attract the attention of policymakers regarding artisanal fisheries is that of Territorial Use Rights (commonly known as TURFs in the literature). TURFs basically consist in the allocation of fishing rights to individuals and/or groups to fish in certain geographical locations. A requisite for these communities to be granted fishing rights is ...
The necessity to move from a traditional fishery management to an ecosystem approach is now acknowledged. Indicators are required to support the development of this approach. For example, community indicators have been proposed to assess the impact of fishing. We tested here the applicability of one such community indicator, the abundance-biomass comparison (ABC method), as a measure of the imp...
