The outcome of the current multilateral trade negotiations in the Doha Round will have large implications on international fish trade. The author highlights the most likely scenarios in areas such as market access and fisheries subsidies, and outlines the very diverse interests and negotiation positions of WTO members.
Resource rentals can be viewed as taxes on scarcity rents or as fees for access to use or utilize the
resource. The Icelandic Fishery Management Act requires that vessel owners pay a Catch fee
(Veiðigjald). This paper discusses how the Catch fee is defined by the Fishery Management Act.
Secondly...
Plant growth stages are identified as distinct morphological landmarks in a continuous developmental process. The terms
describing these developmental stages record the morphological appearance of the plant at a specific point in its life cycle. The
widely differing morphology of plant species consequently gave rise to heterogeneous vocabularies describing growth...
European eel (Anguilla anguilla) is one of the most important commercial species in France (eel larvae (glass eel) exports to Asia valuing more than 60 million euros in 2005) but also an endangered species with regard to the dropping recruitment. This species is particularly sensitive to oceanographic and climatic factors...
To the surprise of government as well as NGOs, village-level caste organizations - or panchayats - played a significant role in the post-tsunami relief effort to fishermen in Tamil Nadu, India. This paper discusses the pro-active role of caste panchayats in relief from the perspective of social resilience, that is...
Understanding how silvicultural treatments and changes in the forest resource will affect wood quality characteristics, including heartwood natural durability, is a critical need for forest managers. Because heartwood properties can be affected by environmental disturbances, including silvicultural practices used to grow trees faster, we need to know if increased growth...

Ocean color remote-sensing systems require highly accurate calibration (<0.5%) for accurate retrieval of water properties. This accuracy is typically achieved by vicarious calibration which is done by comparing the atmospherically corrected remote-sensing data to accurate estimates of the water-leaving radiance. Here we present a new method for vicarious calibration of...
Design and control of vector fields is critical for many visualization and graphics tasks such as vector field visualization, fluid simulation, and texture synthesis. The fundamental qualitative structures associated with vector fields are fixed points, periodic orbits, and separatrices. In this paper we provide a new technique that allows for...
Data from three micronetworks with eddy correlation data and three additional micronetworks without eddy correlation data are analyzed to study the spatial variability of surface air temperature in complex terrain. A simple similarity relationship is constructed to relate the spatial variation of air temperature along the slope to the thermal...
This paper shows a small sampling of the atmospheric fields provided by the
Moderate Resolution Imaging Spectroradiometer (MODIS), which is installed on both the

We compared brood sizes among adult female Euphausia pacifica Hansen, 1911 from 3
populations in the North Pacific: Puget Sound, Washington, USA; Toyama Bay, Japan; and the Oregon coast, USA. Additionally, we used multiple linear regression models to compare the interspecific brood size as a function of female length and...
Maximizing profit and value added are central objectives when fishing rights are distributed. Financial profitability on a company level traditionally measures the return on total assets. Value added on the national level is the net (or gross) national product, and is the total profit of investments and wages and salaries...
The origin of high hole conduction in BaCuQF (Q=S,Se) was investigated by photoemission
measurements and full-potential linearized augmented plane wave band-structure calculations. In
both compounds, the large dispersion near the top of the valence band is realized by admixed states
of Cu 3d and S 3p or Se 4p orbitals,...
Soft white winter wheat grown in western Oregon requires a spring application of nitrogen (N) fertilizer for optimum production. Determining the amount of N to apply has been a challenge for growers because wheat is produced in numerous rotations that provide varying amounts of N to the wheat crop. Inadequate...
