How much do we know about how our tuna is really caught? According to this video, not much at all.

Even if we always look for a sustainable fishing sign on our seafood when we shop, it looks like we still might not be supporting the good guys....

This terrible video of secretely filmed footage shows how sharks, rays and turtles are wiped out by destructive fishing methods used by tuna giants Princes and John West.

Getting caught in the giant nets, the animals will be tossed overboard, dead or dying.

While this video is a hard watch, its important we're all aware of the way our food is produced, in order to put a stop to these cruel methods.

Show you want this kind of fishing to stop by sending a letter to the managing directors of Princes and John West right here.
