2. Global Population is Increasing World Total Developing Countries Developed Countries Depending on assumptions about affluence, diet composition and food waste these figures imply an increase in total food production of 50-70% of current production & consumption.

4. What about fish? Total global consumption is increasing because of population increase and increased consumption per head. But FAO says: One-quarter of the world's fish stocks are overexploited, depleted or recovering from depletion. There is no possibility of increasing fishing activity; in some cases the stocks may decline further. About half of the stocks are fully exploited. They are being fished at or close to their maximum sustainable limit. There is no room for further expansion of fishing activity. Around one-quarter of fish stocks are underexploited or partially exploited and could perhaps produce more.

5. Trends for Fish? Aquaculture provides an increasing proportion of fish supply; this will continue to rise. Global aquaculture production is circa 67 million tonnes. Most is produced in China /Asia. Main species there are low value carp, tilapia and other fresh water fish. EU production is relatively small but EU is the largest global importer of fish and seafood products and is only 40% self sufficient in supply. EU has a major structural deficit in fish supply.

14. Feed and Nutrition A conversion ratio of caught fish to farmed salmon of 5:1 is often quoted. This figure is incorrect and based on an incorrect set of assumptions. Modern salmon nutrition and aquaculture feed use provides a conversion rate of 1.25:1. However, about 25% of fish meal is derived from waste from fish processing. Inclusion rates of fish meal in salmon diets have been reducing progressively as feed technology develops. The notion that salmon farming is ‘not sustainable’ because of its fish-feed needs is incorrect.

20. Why are farms distributed like this? History, Policy, and Planning Salmon Catch Distribution Historically salmon farming started in west coast and island areas because of the water quality and suitability of sites. Government Planning Policy in 1997 to locate farms to the west coast and islands.
