  4. The regulations are viewed by the fishers as opposing rather than supporting their interests and this manifests itself as a reduced compliance to ‘the letter’ as well as ‘the spirit’ of the regulations. • sustainability

  5. Solon (Athenian statesman and lawmaker, c. 638 BC–558 BC). He was challenged by the problem how his countrymen’s greed could be kept within bounds by means of laws. He resolved that he should frame his laws in such a way as to make it to everybody’s advantage to follow them to the letter and the spirit.

  6. ‘perverse’ incentives • By-catch limits / catch composition rules as percentage: • E.g. a lower cod percentage may be achieved by increasing the catches of other species … promoting use of smaller mesh gears…

  7. ‘perverse’ incentives • Landings quota rather than catch quota (discarding is legal): • discarding of overquota catch in mixed demersal fisheries.

  8. Species A TAC or quota Species B TAC or quota Fishing effort

  12. Real Time Incentives (RTI) • Each vessel gets an (annual) quota of RTI credits; • RTI-credits or RTIs can be seen as fishing-impact equivalents Kraak et al. 2012. 21st century fisheries management: A spatiotemporally explicit tariff-based approach combining multiple drivers and incentivising responsible fishing. ICES Journal of Marine Science

  13. Real Time Incentives The fisher is free to fish where and when he wants, given the tariffs… No catch/landings QUOTA Kraak et al. 2012. 21st century fisheries management: A spatiotemporally explicit tariff-based approach combining multiple drivers and incentivising responsible fishing.

  17. Real Time Incentives • RTI system does not prescribe and forbid • allows fishers to fish wherever and whenever they want • ‘costs’ internalized and have to be ‘paid’ by the fishers (in ‘reduced fishing opportunities’) Kraak et al. 2012. 21st century fisheries management: A spatiotemporally explicit tariff-based approach combining multiple drivers and incentivising responsible fishing.
