Engage the virtuous spiral in fisheries

Acting with imperfect information, fisheries policymakers and managers must try to balance tradeoffs of fisheries short-term productivity against long-term environmental, economic and social sustainability.

Alternatively, both environmental and fisheries policy strategies could engage a virtuous circle by bridging the historical divide between fisheries and nature agencies.

Hence, a long-term win-win situation could better emerge, and by propagating the change induced by the reduction of fishing impacts to other supportive marine ecosystem components (habitats, non-commercial marine species), the fisheries management could contribute to secure future fishing opportunities for the fishing fleets along with fulfilling the market demand for seafood and ensuring coherence in meeting national environmental targets.

Building on previous scientific works, we contributed to making this point more apparent in:

Fisheries impact on the seafloor: a showcase in the Baltic Sea

Lessons learnt:
• Restricting fishing areas does not equate to reducing ecosystem impacts on benthic habitats.
• Displacing fishing efforts can offset the gains in partial habitat protection.
• The benthic status in Kattegat improves more than the benthic status in central Baltic when using spatial management measures.
• Largest improvement is achieved by protecting long-lived communities from high-impact fisheries.
• Healthy fish stocks reduce the risk to both the seafloor integrity and fishery economics.

see to see what happens when contracting for example 50% of the fishing effort extent on the core fishing areas, on a pdf presentation here from the HELCOM Action project. Full publication at https://doi.org/10.1016/j.fishres.2020.105681
