Pesca, pescado e combustíveis

Deverão os governos europeus ignorar os protestos dos pescadores para salvar a pesca?

"Herring fishermen in Canada may use only 30 litres of fuel to catch a tonne of fish, because they can throw their nets nearer to home (a practice so cheap that herring is used as lobster bait). European herring fishermen burn 100 litres a tonne, even when using the same (highly fuel-efficient) technique of throwing a purse seine net round a school of fish. Fishing methods matter, too. It takes lots of fuel to pull a heavy net behind a trawler, or tow long lines with hooks for prey like tuna: figures of 3,000 litres of fuel per tonne of fish are common."
