Document Summary
Relationship between aquaculture (increasing) and wild capture fisheries (decline) Technology and intensity of effort is improving, and despite pressures to capture more, there isn"t because we have exploited what"s available for wild capture fishers. Relative contribution to aquaculture and culture fisheries to food fish consumption (decreasing due to exploitation and increase in population)- china has a big impact. Net exports of selected agricultural commodities by developing countries (biggest export is fish) World agriculture production and relative share by culture environment (what kind of aquaculture is happening out there- 2/3 is freshwater, marine is in the middle, and brackish water is low)- freshwater aquaculture is much bigger than marine aquaculture. Canada is distant 3rd to norway and chile in salmon production (up to 2 million tonnes out of worldwide total of 80 million tonnes) Top ten exporters and importers of fish and fishery products (china is growing, canada is not growing as much) Overall, canada"s aquaculture activities are fairly stable.
