PANDORA's Toolbox


Short-term forecasts underpin management recommendations for Total Allowable Catch (TAC) and effort.

Using the updated and newly develop assessment models from PANDORA together with monthly to annual environmental predictions, the project provides improved short-term forecasts. Moreover, PANDORA pioneers in the use of a risk-based framework to evaluate trade-offs between stocks and fleets, and between catch yields and the risks of stock depletions in a context of varying sustainable yield. This augments
more traditional approaches and add value for decision-makers and other stakeholders.

When it comes to the socioeconomic impacts on and of fishing in European seas, a series of bio-economic simulations explores longer-term scenarios for ensuring stable positive economic performance and employment opportunities. To describe empirically the direct drivers of fisheries in Europe these scenarios focus on two key economic aspects: profitability and employment.

​​​​​​​​​Mediterranean Surface Exploration Tool

This tool (located at allows exploring various ocean variables providing information on the sea surface of the Western Mediterranean Sea. These variables include five key Essential Ocean Variables, temperature, salinity, sea level, chlorophyll-a and currents, and two additional variables, temperature and salinity fronts, derived from the EOVs. The information is obtained from the SOCIB Western Mediterranean Operational system and from satellite data provided by Copernicus Marine Service (CMEMS). This tool is aimed for a wide range of end users in the field fisheries sustainability, conservation and education. All data handled by the tool is publically available from the SOCIB and CMEMS data servers

Size based Plankton simulation

Simulate a plankton ecosystem in the upper part of a watercolumn ( Cell size is the only trait characterizing each plankton group. All groups are able to perform photoharvesting, taking up dissolve nutrients and carbon, and do phagotrophy. The trophic strategy is an emergent property.

Single-species size-spectrum simulator

This applet ( simulates the size distribution of a single species (blue) subjected to fishing (red). The filled area is the mature individuals and the colour whether recruitment is high (green) or low (red). The species is characterized by the asymptotic (maximum) size (W∞) and a set of non-dimensional parameters.

Multispecies consequences of fishing in the North Sea

This ensemble application ( uses the novel ensemble methods of Spence et al. (2018) to combine four mechanistic multispecies fish community models to produce, with quantifiable uncertainty, predictions of equilibrium response of 9 key commercial North Sea species to different rates of fishing, in terms of SSB and risk of depletion.
