Recommendations to increase fish consumption in order to gain the benefits of omega-3 and omega-6 abound. People in developed countries have been urged to increase their consumption of fatty fish two to three fold.
However, the environmental sustainability of these recommendations needs to be questioned.
At current consumption levels global fisheries are in a severe crisis as demand outstrips supply and fish is being diverted from local markets (especially in the developing world) to affluent markets. This affects both the food security of those countries as well as the livelihood of the coastal communities that used to fish these resources.
If the recommendations to increase fish consumption two or three-fold is followed then all trends would suggest that commerical fish stocks will collapse by 2050.
