What will be the effect of spatial restriction on fisheries and on the surrounding environment? Is there any risk of fishing effort displacement and concentration on sensitive habitats? What will be the costs or benefits for fishermen? etc.
DISPLACE: a dynamic, individual-based model for spatial fishing planning and effort displacement - integrating underlying fish population models, check out the paper [here] (http://www.nrcresearchpress.com/doi/abs/10.1139/cjfas-2013-0126#.UoffA2t5mSM) in Canadian Journal of Fisheries and Aquatic Sciences and [here] (http://icesjms.oxfordjournals.org/content/early/2014/12/01/icesjms.fsu215.full?keytype=ref&ijkey=h5gubA8LgO6JmWY) in ICES Journal of Marine Science, and have a look at the DISPLACE blog at http://www.displace-project.org/blog.
A bi-directional model. The DISPLACE model combines the fishing activity and resource dynamics with very high resolution in time, space and fishing units, which is rarely done although it is in literature recognized as necessary. That is, to take into account fish population responses to fishing and induced fishermen behavior, impacting on local scale and on single fishing operation level, in the assessment of various management actions.
An individual-based model. There is a need to better encompass the connection between the micro-scale fishermen decisions and their economic causes and consequences at the macro-scale level (e.g. via the stocks and fish market dynamics) when evaluating the economic viability of the fishing sector and the sustainability of the marine ecosystems (stocks). In the DISPLACE model, vessels are simulated individually to visit their own specific grounds and ports at their own frequency which regenerates the individual fishing variability otherwise usually encapsulated into a regional aggregation.
A supporting tool for impact assessement. We want to develop a collective understanding and a common discussion platform based on quantitative predictions of impacts and beneficial/detrimental effects on fishing activities of any new spatial marine planning project.
Provides input to:
impact on economic returns from traditional fisheries.
effect on MSFD indicators (e.g. spatial fishing pressure/footprint) and their economic value.
Impact assessment of Maritime Spatial Planning MSP on the fishery economy.
