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...

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,...
This dissertation focuses on science relevant to the design and implementation of marine reserves. The chapters explore a range of topics related to among-site variation in population, community, and ecosystem dynamics. My results demonstrate the value and feasibility of integrating this knowledge into more comprehensive conservation and management approaches. While...
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...
