Type of practice:
The bio-economic models EIAA and BIRDMOD (see: http://ec.europa.eu/fisheries/documentation/studies/bioeconomic_models_en.pdf) are used for the purpose of the Impact Assessment on the Common Fisheries Policy. The corresponding IA Report (http://eur-lex.europa.eu/LexUriServ/LexUriServ.do?uri=SPLIT_SEC:2011:0891(51):FIN:EN:PDF) gives an account of this application.
EIAA was originally created to assess the economic consequences of the TAC (ACFM advice). Currently it has been developed to include an optimization module to estimate the number of fishing days under different quota proposals. EIAA provides advice for TAC changes, long-term management plans and days at sea restrictions in an extended version of the model.
BIRDMOD is a simulation model to predict effects of different management policies from a biological, economic and social perspective and consists of 4 modules; a biological, an economic, management and a state variation module.
