SUSTAINABLE FISHERIES• Norway: is now among world leading countries in fisheries and fisheries management.• But: WE HAVE LEARNED IT THE HARD WAY – FROM SERIOUS MISTAKES WITH OVERFISHING AND STOCK DEPLETION IN THE 1960- 70ies.
Depletion of the largest fish stock in the N. Atlantic (NSS- Herring): an eye opener and point of departure for sustainable fisheries management 4,3spawning stock (million tonnes) 15 4,1 12 9 3,9 to C 6 3,7 3 0 3,5 1900 1920 1940 1960 1980 2000 (Toresen and Østvedt 2000)
The main elements for sustainable fisheries Main elements in the management regime for sustainable fisheriesFisheries research: Management Control: measures: -how much fish is Sanctions:- how much fish is caught -Fee available? - who should fish -Fisheries statistics -Arrestment of vessel - how muchExploration rate Exploration pattern IUUN and overfishing International cooperation Stakeholder participation Gullestad et al. 2012
Increased fishing capacity 1950+: accellerating increase in fishing capacity: larger vessels, larger engines, echosounder, sonar, purse seine, power block, nylon, improved navigational systems new species caught still with an open access fishery - until the 1970/80-ies.

Structural policy measures• Limiting access – first as an emergency action => necessary to avoid overfishing• Ending of fishery subsidies• Distribution of fishing rights – individual licenses and quotas• Scrapping schemes/license aggregation schemes
In 2012;modern purse seiner/pelagic trawler (2000 tons) – state of the art fishing gear,equipment, technology etc. do catch more in tones than the old vessels, but - fewer vessels - selective gears (size and species, season, area) - Reduced fishing pressure Increased outcome per fisherman Increased spawning stocks - optimizing long term economic yield based onprecautionary harvest control rules, stable income and F Easier to control and adjust fishery according to biological production andenvironmental conditions
