Concerns about the effects of climatic changes on marine ecosystems are widespread. For instance, climatic oscillations can change water temperature, nutrient dynamics, winds and circulation patterns. These changes can affect survival, growth, reproduction and distribution of species, but the impacts can be also displayed at the population, community and ecosystem level. Global and regional assessments have been initiated to determine the vulnerability fishing stocks to impacts of climate change and fisheries. As expected, the global climate will suffer big changes in next years, and the fishing resources will become increasingly overfished, and will varies along the world, so it is necessary that studies will be made at a local context. The Portuguese coast has experienced substantial changes in climatic events, namely increasing sea surface temperatures, changing wind patterns, intensification of upwelling and frequency of negative and positive phases of the North Atlantic Oscillation Index. Climate change projections indicate that these modifications could have significant impacts on fishing resources in this biogeographical area. To understand the level of fisheries impact to climatic change we will develop a vulnerability framework (based on exposure, sensitivity and adaptive capacity) in a fisheries context providing an index for species/fisheries to climatic change. These will require information on coastal landings data and scientific information about biology and ecology of species and the climate projections that will be compiled from a range of sources including IPCC scenarios of future climate change for Portuguese coast commercial main species. This simple semi-quantitative approach is adopted to pro-mote the use of vulnerability framework for fisheries status assessment as well as development of actions and strategies in areas that are data-limited but necessitate for preparation to climate change.
