Pirate fishing is a global threat to the oceans and those who depend upon them. We hear fine words from governments about tackling the problem – but if they were serious then we wouldn't need to be here and offer our ship to the Guinea authorities. The first thing that must be done is to close ports to pirate fishing boats, deny them access to markets and ensure that companies are prosecuted.

Today we found one pirate -- but we know there is a fleet of them out here and in every other ocean, stealing fish every day.

In the past few weeks we have begun to unravel the web of deceit around pirate fishing. The way the legal and illegal ships work together is designed to deceive, but in the end it is a simple case of stealing food from others.
