Model development (1.3)
- Last Updated: 15 February 2016
The MYFISH work included identifying and adapting the indicators and models required to produce decision support advice. Under MYFISH, a common MSY framework was defined and applied to all regions. The framework ensures that the MSY approach is responsive to specific regional requirements in implementation.
The project has made a specific effort not only to identify indicators and associated reference points, but also to get these indicators accepted and used in management through advice given by ICES. Focus areas included the definition of biomass reference points for exploited stocks (MSFD descriptor 3), Indicators and reference points for GES on biodiversity and sensitive species (MSFD descriptor 1), indicators and reference points of GES of food web indicators (MSFD descriptor 4), indicators and reference points of GES of the pelagic ecosystem (MSFD descriptors 1, 3 and 4) and socioeconomic indicators.
A wide range of different models have been adapted and these developments and adaptions have been described in a long list of scientific manuscripts, significantly lifting the discipline of fisheries, ecosystem and economic modeling by improving topic models focusing on single aspecta as well as the interface zone between topical models. The models together cover both single species and mixed fisheries, fisheries where prey and predators are both targeted by fisheries, small scale and large scale fisheries and fisheries where there are trade-offs between economic and social aspects such as rent and employment. A particular step forward has been in the application of F-arrays, which have been used to provide Maximum Sustainable Yield from models which can otherwise be used to optimize objective functions directly in forecasts.
Decision Support Tables have been produced, reported and initially discussed with stakeholders in all regions (link to DSTs here) and will be used in further consultations of stakeholders. The models are well suited to support the development of new multiannual management plans under the new CFP in task 2.4 and communication with DGMARE and ICES is ongoing to ensure that the resulting models and indicators are used as widely as possible.
