One main goal of the European fisheries policy is to harvest all fish stocks with a fishing mortality in accordance with the MSY concept (Fmsy) in 2015 at latest. However, because of predator-prey interactions and bycatch in mixed fisheries, Fmsy as defined in the current single species context cannot be achieved for all species simultaneously. MYFISH will define MSY in accordance with the ecosystem approach and helps to develop multi-species management plans. These plans will ensure a sustainable exploitation but also take into account economic and social aspects.
One main goal of the European fisheries policy is to harvest all fish stocks with a fishing mortality in accordance with the MSY concept (Fmsy) in 2015 at latest. However, the way to reach this goal is complex, as the harvesting of one stock with Fmsy may lead to negative impacts on other stocks in the ecosystem. Increasing predator stocks lead to higher natural mortalities for prey stocks and finally to a lower yield from these prey stocks available to the fishing industry. In addition, the economy of fleets and social constraints have to be taken into account to reach a sustainable use of marine resources. MYFISH will define sustainability in the context of the ecosystem approach to ensure that "Good environmental status" can be reached as envisaged by the Marine Strategy Framework Directive (2008/56/EC) without ignoring economic and social constraints. Existing ecosystem and bio-economic models will be modified to allow for the maximisation of yield under certain constraints. Management plans will be developed with the help of various stakeholders (fishing industry, NGOs, fisheries managers) from the different regions (Advisory Councils) to implement the MSY concept inside an ecosystem approach to fisheries.
Politicians, science, fishing industry, media
This project deals with complex bio-economic and multi-species models to identify optimal harvest strategies. There is a pronounced role of stakeholders in the project because often trade-offs have to be solved that go beyond scientific decisions.
