Ecologically safe fishing levels must be set in a precautionary way that takes into account our incomplete understanding about the workings of complex ecosystems. The net's circumference measures a mammoth 2048mtrs, producing a mouth opening area of 22,900 sq. mtrs.
Ships deploying such nets have a capture rate of about ten tons of fish per hour.
A modern 'factory' supertrawler can be longer than a football field and capable of catching and processing into various products up to 200 tons of fish daily. Eighty percent of the world's marine catch is produced by just 20 fishing nations.
