A higher dependence on the resources motivates to community participation on resources management. Uses of common property resources are not benefit to each and every person in equal rate of resources since magnitude of the resources extraction depend on the number of criterion. Selecting of the interest group for the...
Most fishermen are faced with several options in both long and short term planning of their activity. In this paper we study fishers short term decisions when different seasonal fishery options are available. This involves choices of spatial and temporal allocation of effort as well as use of varying fishing...
Having excess weight carries a negative social stigma in the U.S. Previous research has shown that experiencing stigma has negative physical and mental health consequences. Few studies have examined how experiencing weight stigma might act as a barrier to engaging in healthy behaviors among older adults. The purpose of this...
Here the diversity and phylogeny of the genus, Sthereus Motschulsky, 1845, and its nearest associates in the large subfamily Molytinae are explored through molecular and morphological characters. Sanger sequencing of five genes determined that Sthereus is not monophyletic. Instead, the one species in the genus Gastrotaphrus Buchanan 1936, G. barberi...

The Florida spiny lobster trap certificate program (TCP) is one of the oldest U.S. fisheries programs involving tradable effort permits. Under the TCP, fishers must own a certificate (and pay an associated annual fee) for each trap used. The program was created in 1992 to address overcapitalization amid growing social...
Considerable attention has been applied to the development of models explaining how fish stocks change over space

Phytophthora species were systematically sampled, isolated, identified and compared for presence in streams, soil and roots of alder (Alnus species) dominated riparian ecosystems in western Oregon. We describe the species assemblage and evaluate Phytophthora diversity associated with alder. We recovered 1250 isolates of 20 Phytophthora species. Only three species were...
The sperm whale (Physeter macrocephalus) shows some of the most derived characteristics of any mammal: a large body size, large brain, complex social organization and a capacity for deep foraging dives that few other marine mammals can match.

Recently, changes in human performance following whole-body vibration (WBV) training have been attributed to enhanced neuromuscular function. However, the exact neural and muscular mechanisms responsible for these changes remain less understood. The purpose of this study was to evaluate the acute and chronic effects of whole body vibration on the...
A recent analysis of the potential for management cost recovery in the UK suggested that such a policy would be detrimental to UK fishers if other European countries did not implement a similar charging policy. Most of the waters exploited by UK fishers are also exploited by fishers from other...

The earth is undergoing a “biodiversity crisis” characterized by loss of populations, species, genetic diversity, and ecosystem services. Part of this crisis consists of population declines, extinctions, and increased incidence of deformities in amphibians. It is unknown whether deformities contribute to these declines. Many cases of population declines in amphibians...

Individual transferable quotas (ITQs) have been used in several countries worldwide to regulate access to
marine fisheries. While ITQs can improve the economic efficiency of fisheries, in practice they are not a

Despite the growing popularity of culture-based fisheries (CBFs) associated with village irrigation systems (VISs) in Sri Lanka, there is little knowledge about factors that influence productivity levels. To redress this, primary data from 325 fish farming groups in two districts (Kurunegala and Anuradhapura) are used to estimate a stochastic translog...
The Abalone Fishery in one of Victoria’s most valuable commercial fisheries and most of the catch is exported to international markets in Asia (Japan, Hong Kong, Singapore, China). Target species consist of blacklip abalone and greenly abalone (<1% of total catch). The fishery is quota managed, and the total allowable...
To reduce fleet capacity in European fisheries is an important objective of the European Union’s Common Fisheries Policy. The success of such programmes depends both on the variation and the level of efficiency within the fishing fleets. If vessels with significantly lower efficiency level than average are decommissioned, the actual...
Lobster (Homarus americanus) ranks first in Canada’s fisheries, but Quebec lobster represents only 6% of eastern Canada landings. During the peak of the fishing season in Quebec as elsewhere, supply is at its maximum and price is the lowest. For this reason, there has been considerable interest in Quebec in...
Rapamycin (5) was isolated in 1975 from the soil bacteria Streptomyces hygroscopicus and its structure was determined from spectroscopic techniques and an x-ray crystallographic analysis. Although it was initially found to exhibit antibiotic activity, it was subsequently shown to possess potent immunosuppressive activity as well.

Management of the Danish protein fisheries in the North Sea has during recent years become increasingly politicised, as various stakeholder groups are seeking influence on the decision-making process. In relation to management of the sand eel and Norway pout fisheries, two different issues are debated. In the sand eel fishery,...
Over fishing, by-catch of non-target fish species, marine mammals, seabirds, and damage to benthic habitats remain serious problems in fisheries management. Management methods based on traditional command and control (CAC) approaches may meet with initial successes yet additional progress is often marginal, requiring managers to implement additional regulations to achieve...
The seismicity of the North Atlantic was monitored from May 2002 to September 2003 by the ‘SIRENA array’ of autonomous hydrophones. The hydroacoustic signals provide a unique data set documenting numerous low-magnitude earthquakes along the section of the Mid-Atlantic Ridge (MAR) located in a ridge-hot spot interaction context.

The Australian Harvest Strategy Policy requires that maximum economic yield (MEY) be the target in all Commonwealth managed fisheries. For multispecies fisheries, unlike single species fisheries, the optimal yield is not independent of the optimal yield of the companion species (i.e. those species with which it is caught). In fisheries...
Entrepreneurial New Zealand harvesters created a viable diving fishery for King Clams, Panopea zelandica, in the 1970's

An application to specific conditions of shrimp culture in Mexico is presented. The optimal harvesting rule is numerically found for different economic...
This paper analyzes optimal fishery management in the presence of an endangered predator that competes with humans for a commercially viable prey. Because traditional predator controls are not possible when the predator is endangered, we focus on harvest effort controls over the prey’s habitat as a means to maintain the...
Key decision variables in aquaculture management are stocking level, feeding schedule, temperature
control and batch length. In many management problems with an infinite planning horizon, the aim is to

The importance of migration rates and growth rates of both target and bycatch species and costs are analyzed. Pure open access equilibrium harvest of target species and stock level of bycatch species are compared...
The Australian federal fisheries policy identifies maximising net economic returns as the primary objective of fisheries management. This has largely been interpreted as maximising the net economic yield (MEY) in fisheries. For multispecies fisheries, this has been based on maximising the net present value of total profit in the fishery...
