Aquaculture and sustainable fisheries for nutrition

Learning from Norway

Ole Arve Misund, Livar Frøyland, Ingvild Eide Graff, Gro-Ingunn Hemre, Geir Lasse Taranger

Norwegian Fisheries:~ 80 fish stocks, 10 000 fishers, 6000 vessels, 2.5 mill ton catch- Well regulated: TAC science based, technical reg., precautionary approach, harvest control rules, fisheries monitoring and inspections, biodiversity conservation

Norwegian aquaculture• 1.2 mill. tons Atlantic salmon (Salmo salar),

70 000 tons of rainbow trout (O. mykiss)• Challenges in salmon aquaculture:

– Environmental sustainability (e.g. sea lice)– Sustainable feed resources

• Considerable R&D to develop other species for aquaculture e.g. Atlantic cod and Atlantic halibut; prod. low due to disease, prod. & market issues

• Minor farming of mussels and lobster

Norwegian farming of salmon, trout & other species 1980-2014

Research in the whole food chain –from fish feed to seafood and health effects

National policies to support fish consumption

Debate about undesirable substances; Limit to two meals of fatty fish per week?

Directorate of health (2011):Eat 2-3 seafooddinners per week

Age women

Oily fish only 14 g/day(Mean for all women, 2011)

Wild salmonFarmed salmon

EFSA: 0,25 g/day (2010)

Conclusions:• Seafood may contribute with nutrients not

commonly found in other food items• Farmed salmon an important source of

marine omega-3 fatty acids, possible to tailor with vitamin D

• Fisheries and aquaculture may contribute to food and nutrition security
