Wow amazing, what a grate stuff. And this is really hard work. Hands on for all the researchers.

That's entirely believable. Scott Cassel has been working in the Sea of Cortez with those critters for a while and has been saying these animals are now inhabiting the niche left behind from blue sharks and other predatory species taken out by rampant fishing all along the west coast.

If you want the truth about a fishery ask a fisherman.

Patric, that's disturbing news. I'll share with our juvenile white shark research team and our Mexican colleagues.

We're pretty sure that this was truly accidental catch. The fisherman took his ponga (small boat) father offshore than usual to avoid Humboldt squid preying on his catch, and left his gillnet in the water for a week when bad weather prevented him from getting back out to check it.

Whites in Ensenada are targeted by long liners and small co-ops, the meat is then sold as swordfish in local markets.

After speaking with one family run operation two years ago I was told they often catch young of the year and have two choices. Put the dead shark back into the water or make a few pesos from the animal at market.

More sea farming is needed which will decrease the need for indiscriminate fishing practices like gill nets.

Sea farming is the future.

Great white sharks are protected in California and Mexico, and still they are caught accidentally in gillnets.

By working with commercial fishermen, we're helping to document how significant an issue this is, and what kind of impact it's having on the regional population of great white sharks.

Fisheries managers in both countries regulate use of gillnets (such as the seasons when they can be used, and the locations where they're permitted). Ideally, the data we're gathering will inform those regulations and better protect young white sharks.

For now, follow our Seafood Watch guidelines to make sustainable seafood choices. Unwanted catch of protected animals (like great white sharks) is one of the key factors that affects whether something winds up on our Red list to avoid.

What, if any, efforts are being made to do something about the gill nets? It's heartbreaking to know that these sharks continue to killed like this! Especially a long-lived shark like the Great White that is in trouble. This shark will never breed now. I wish we could do move to stop this endless exploitation and corruption of the sea. Is there really anything we can eat from the sea that doesn't have an environmental cost, your seafood card quide notwithstanding?
