Background. Ampelisca eschrichtii Krøyer, 1842 of the Sakhalin Shelf of the Okhotsk Sea, Far Eastern Russia, comprise the highest known biomass concentration of any amphipod population in the world and are a critically important prey source for western gray whales. Growth and reproduction in this population has not been apparent...

The motivation of this paper is to detail the application of Markov chains in
simulating fleet dynamics in Australia's Northern Prawn Fishery (NPF).
The Markov chains are enhanced through the use of the multinomial logit
(MNL) and Seemingly Unrelated Regressions (SUR) models to explain
transition probabilities. The terms MNL Markov...
Small-scale fisheries play an important role in generating employment, income and livelihood to the
fisherfolk. It constitutes 81 per cent of the total fisheries sector in India. But, this sector remains neglected
and the fisherfolk are socially and economically backward. Even after six decades of planned
development nearly 62 per...
Conservation and management of North American West Coast fisheries
encompass a broad array of issues including the economic, spatial, and
temporal relations between the coastal pelagic species live bait fishery and
the highly migratory species recreational fishery. For the better part the
century, the live bait fishery has supplied live...
Throughout the Indo-Pacific region, communities are increasingly
empowered with the ability and responsibility of working with national
governments to make decisions about their marine resources. In some
instances, co-management arrangements have been successful at
conserving marine resources by developing locally appropriate rules to
limit overexploitation. These examples have often prompted...
In his report the economics of
ecosystems and biodiversity, P. Sukhdev compared the valuation of
ecosystem services and biodiversity to a compass which helps decision
makers to engage in the conservation of environment and against the loss
of biodiversity. Following this road, the authors present the results of an
economic...
Based on empirical studies carried out in Reunion Island, Moheli
(Comoros) and Madagascar, this communication deals with the non
biological productions of MPAS as a major driver of the marine resources
conservations governance. Three types of productions can be drawn for
each type of stakeholders: territorial, behavioural and economic. Firtly,...
The purpose of Oregon's Nearshore Research Inventory (NRI) project was to inventory and map the current and future use of Oregon's nearshore environment by the scientific research community for use in Oregon's marine spatial planning process. Spatial and qualitative data on the use of Oregon's ocean and coast by the...
The goal of this thesis is to advance the methodology and thought regarding the transferability of ecological estimates of ecosystem services. Conceptually and in practice, ecological estimate transfer parallels economic benefit transfer in ecosystem services research and policy, yet the literature for benefit transfer predates ecological estimate transfer by several...
The Chiloe archipelago (Patagonia, Chile) economy lies upon agriculture, fisheries and aquaculture. The marine activities were recently affected by an epidemic crisis in salmon farming and a market crisis for most of the seafood products, including seaweeds. Two Marine Reserves (Putemun and Pullinque) in this island were also badly impacted...
Marine conservation measures such as moratoriums challenge the economics of fisheries. Efficiency of moratoriums depends on the acceptation by fisheries of such conservation measures. If the measure is unaccepted by fisheries the moratorium is not respected which leads the stock to extinction. The purpose of this article is to identify...
Despite its promise as a potentially beneficial new source of energy, the ocean-based renewable energy industry is still in its infancy, and like any new idea there are many unknowns with the potential to affect both people and our natural environments. A permit for marine renewable energy (MRE) must cut...
The National Park Veracruz Reef System was declared a marine protected area by the Mexican government in 1992. It contains 23 reefs presenting different degrees of environmental deterioration mainly due to the influence from nearby rivers, its proximity to the port city of Veracruz-Boca del Río and the currents patterns....
Oregon's ocean waters are a potential source of wind, wave, and tidal energy; of interest to renewable energy entrepreneurs and to the U.S. government as it seeks to bolster energy security. In order to install technology to capture this energy, however, it may be necessary to mitigate conflict with existing...
The push for ecosystem based management has opened up not only for including more of the natural
systems when managing fish resources, but also a broader perspective on the human systems, and the
diverse activities in the sea. This is reflected for instance in the EU Maritime Policy where fisheries...
In this paper the emphasis is put on an important aspect of renewable resource use that was disregarded until now. It is the evolution of environmental carrying capacity which is traditionally interpreted as a maximal population level that can be supported by the environment (or by habitats of which it...
Eritreas Coastal Marine and Island area covers more than 121,000km2, include over 350 offshore islands and 1,350km of coastline (18% of the Red Sea continental coastline) not including the islands. The total coastal mainland population is 73,000, and only ten out of all the islands are inhabited with a total...
Reefs and lagoons ecosystems of French Polynesia have been since a very
long time the support of important traditional activities. They are today
concerned by conservation public policies, which have considerable
consequences about the relations between local societies and their
environment.
The necessity to stop the degradation of marine biodiversity...
If the role of MPAs as a conservation tool is now widely demonstrated
even with some variability, their effects on fishery yields, tourism revenues
and social aspects are only confirmed by very few studies. More than 550
MPA now exist in the South Pacific mostly community based managedand
the expectations...
As interest grows in developing devices to harvest energy from ocean waves, tidal currents, and offshore wind, concerns over possible environmental effects from such devices also grow. One such concern is over the induced electric fields and the generated magnetic fields from generators and their associated submarine power cables in...
