The overfishing of stocks of commercial fish is a severe and complex problem around the world, with many well-known species including cod and plaice in serious decline and at risk of complete collapse (7). As the technology involved in fishing has improved and the number of faster, more efficient boats has increased, populations of fish have decreased further and have been unable to reproduce fast enough to compensate for the massive losses (7). The problem can be summed up as: 'too many boats chasing too few fish' (6).
