DISPLACE – An individual-based model of fishing vessels

DISPLACE stands for a Dynamic, Individual-based model for Spatial fishing PLAnning and effort displaCEment. A paper in press can be found here

A wiki page has just been set up at to host documentation and links to the source code repository (in progress). Make it transparent, peer-checked and prone to cooperative development.

The DISPLACE project is attempting to develop and provide a platform primarly for research purposes to transform the fishermen’s detailed knowledge into models, evaluation tools and methods that can provide the fisheries with research and advice. We need also models that can serve as a basis for decision support tools for (fishery) managers.  Among other goals, economic benefit of stock replenishment and sustainable harvesting should be demonstrated. As a general rule, it is important to evaluate the combined ecological and economic impacts of fishery management before its implementation (i.e. impact assessment).



An individual-based model (IBM) on a per-vessel basis covering several fisheries and stocks is a benchmark tool capable of integrating fishermen’s decision-making processes when they face changes in fishery management, economic factors influencing the fishery, economic viability, and underlying stock conditions, including spatial and seasonal patterns in resource availability.
