A key challenge for resource and landscape managers is to predict the consequences of climate warming on streamflows and water resources. Different approaches are being developed to forecast the direction, magnitude, and timing of future streamflow changes in specific landscapes. One approach that is being utilized in the Pacific Northwest...
Climate changes. That’s what climate does. It is a natural and dynamic process. The National Weather Service (NWS) recognizes on-going climate change by publishing new figures for average climate every ten years. Climate averages for precipitation, temperature, and other weather parameters are computed on a 30 year basis but only...
Climate change and climate-induced changes are expected to increase in the future and are likely to cause adverse impacts, especially on aquatic resources and coastal communities, by affecting the productivity and distribution of fish stocks. This will have serious implications on future demand and supply of fish at the global...
After 1950 traditional herring fisheries were revolutionized by a new technique: sonar, power block, larger
nets and bigger boats. As a result all major herring stocks in the North East Atlantic Ocean collapsed. The
most dramatic decline was that of the Atlanto-Scandian stock between Iceland and Norway from millions
of...
To achieve sustainable fisheries, ecosystem-based fisheries management
yields increasing attention. However, so far mainly single-species models
are used to develop management advice, not accounting for species
interaction. In particular many traditional fisheries economic models have
been criticized by biologists, especially if results were gained by rather
simple biomass models. Therefore,...
This study investigates the economic impact to fisheries and associated sectors if wild fisheries continue operating to
2030 without considering the effects of climate change. Estimates of climate change impacts in Australian fisheries
and their associated probability distributions were derived from the literature and expert consultations. An Input-
Output model...
This paper looks at the possible consequences and adaptations to Climate
Change for fish and people, particularly the marginal and poor fishers in
Bangladesh. Fish from Bangladeshs vast inland waters are vital to millions
of marginal and poor people, but catches and species diversity have been
declining due to the...
The spatial distribution of Norwegian salmon farming depends on license
allocation and physical conditions, with politicians defining the former.
Currently, relocalization of these is not permitted. With an expected
temperature increase in Norwegian waters, this study analyzes increased
temperatures impact on the spatial distribution of production and
employment. Four scenarios...
The international council for the exploration of the seas (ICES) publish
annual reports on fish stock assessments. Based on the stock assessment
data for the North-East Arctic cod we estimate the effective fishing
mortality, establishing coefficients for the catchability-at-age and the
annual fishing effort. The fishing effort estimates are then...
