Tom Heap meets the activists hoping to bring an end to illegal fishing by tackling the problem head on: by getting in the way of pirate fishermen.

The Black Fish is a relatively new NGO (Non-Governmental Organisation) who aim to stop the fishing of juvenile Bluefin Tuna in the Mediterranean and prevent to use of illegal drift nets - by cutting them. Drift nets were banned by the United Nations in 1992 but they are still used illegally around the world.

The Black Fish are soon to launch unmanned reconnaissance aircraft in the Mediterranean to monitor illegal fishing and find out exactly who is doing it and where.

Tom also meets campaigners who believe that the only way for fish stocks to recover is for a ten year moratorium to be imposed, allowing species of fish to become plentiful once more.
