While the impacts of long-term climate change trends on glacier hydrology have received much attention, little has been done to quantify direct glacier runoff contributions to streamflow. This paper presents an approach for determining glacier runoff contributions to streamflow and estimating the effects of increased temperature and decreased glacier area...
A guide for 4-H food preservation club leaders that includes tips on organizing content for club meetings, teaching techniques, food preservation experiments and standards for evaluating preserved food products, and a short history of food preservation.
Sixteen sampling alternatives were examined for their performance to quantify selected attributes of overstory conifers in riparian areas of western Oregon. Each alternative was examined at eight headwater forest locations based on a 0.52 ha square stem maps. The alternatives were evaluated for selected stand attributes (trees per hectare, basal...
Changes in ownership of limited entry permits by “local” residents of the region where a fishery occurs
may have significant economic and social implications for fishery-dependent regions. This paper
examines changes in local permit ownership in Alaska salmon fisheries, for which a long-term decline in
rural local permit ownership is...
One component of the Bering Sea Integrated Ecosystem Research Project
(BSIERP) is a spatial economic model that predicts changes in fishing
activity in the Bering Sea pollock fishery that may result from climate
change. Models such as the one employed here have been used in the
Bering Sea and elsewhere...
Based on the evoked set analysis, a group of factors driving knowledge and preferences about fish farmed species are investigated with three different samples. Samples were collected in Spain, into a nationwide study about knowledge and assessments about aquaculture, funded by the General Secretary of Marine Fisheries of the Spanish...
This paper discusses the use of resource assessment surveys as the basis for effective fisheries management drawing on the resource assessment survey of the Arabian Sea coast of Oman. This survey, completed in 2009, has been undertaken in the context of the primary aim of the Oman Ministry of Fisheries...
Vietnam is the peninsular country and lying in the area of monsoon tropical climate therefore has very diversify and abundant and valuable fish resources. Since long time ago the fisheries resources in natural water bodies (as in dams, rivers, lake, canals, sea) have been concerned as common property (and is...
This paper investigates interactions between recreational and commercial fisheries. It introduces the idea of a protected area for recreational fisheries, as a way to reduce conflicts between the two sectors and to preserve the natural resource. It is demonstrated that without a protected area for recreational fisheries, open access may...
The coastal fishery in French Guyana is a challenging case study for the implementation of the ecosystem based fishery management. Although the current situation of this small scale fishery could be considered as satisfactory, the viability of the fishery can be questioned. Indeed according to demographic scenarios, the growth of...
Species within marine ecosystems are known to be interconnected. This is
a result of many factors including predation and competition for resources.
Despite this, many fisheries are still managed using a single species
framework. This paper uses cointegration analysis to quantify the
relationship between different fish species. Cointegration is a...
Tuna fisheries around the world are governed by Regional Fishery Management Organizations (RFMOs), whose membership includes both harvesting nations and nations in whose waters the targeted fish populations reside. The outcomes of the policies established by an RFMO will depend on subsequent interactions among the fleets, the fishing sites and...
Economists have long promoted fishery rationalization programs, but ITQs may fail to address the
ecological consequences of fishing. Of particular concern is that economic incentives to harvest larger
fish (due to size-dependent pricing or quota-induced discarding) can destabilize fish populations or lead to
evolutionary changes. A substantial theoretical literature in...
The credit crunch has had a dramatic effect within the seafood industry. Recent years saw a buoyant UK economy with increasing sales of chilled seafood material and a growing interest in sustainability. Credit tightening and declining consumer confidence has placed pressures on these trends. This is unlikely to be reversed...
