Fish-MIP documents and protocols

The challenge

Marine ecosystem models use very different basic structures to represent food-web or ecosystem components and the links between them. Ecosystem components can be represented by size classes, functional groups, trophic levels, species groups, and life-history stages, whereas links can be represented by who-eats-whom networks, diet composition or energy transfer. Another challenge is that our models do not all use the same input and output variables. Finally, there are limited observational data for historical runs and model validation, and limited data on spatially resolved fishing effort.

Simulation protocols and uploading results

The FishMIP Phase 1 (2020) protocol can be downloaded here.

The ISIMIP2a simulation protocol represents the choices we have made in order to compare as many global and regional models as possible. These include common inputs with respect to climate, physical and chemical data (temperature, currents, salinity, pH, oxygen), biological data (e.g. primary production, phyto- and zooplankton), and fisheries data (effort, catch, fisheries mortality) as well as common outputs including fish biomass and catch as well as other ecosystem parameters. The ISIMIP2b and 3a/b protocols can also be found on the ISIMIP website.
