Introduction:
SSFs → Own characteristics that often affect prices. First‐sale prices are key for the sustainability of SSF,often price‐acceptors → influence of supra‐local factors (exports, imports, value‐chain forces) and industrial fisheries. Certain local/regional SSF management measures also aim to have effects on this price: fisheries regulation, commercial strategies, labelling, etc....
Context and objective: Beyond leisure and food (sea ES) → MRF boosts maritime economies, but not a formal industry in our economic accounts. EU DCF → increasing focus on MRF, to be considered in commercial fisheries management decisions (CFP). Limitations of traditional approaches (aggregated expenditures,non‐market microeconomics) to assess MRF economic...
Marine recreational fishing (MRF) is a leisure activity and a cultural ecosystem service that, beyond the welfare obtained by its practitioners, has an interesting potential to boost maritime economies. However, it does not represent a formal sector on the national accounts and, in Europe, it lacks a systematic and common...
First-sale prices of fish respond to both local and global drivers, and artisanal fishermen are often considered as price-acceptors due to their limited capacity to influence them, a key issue for their survival and value added creation. However, in artisanal fisheries, the frequent lack of data hinders us from understanding...
