Dolphin Safe Tuna




TUNY brand tuna is canned in Mexico by TUNY, the second largest tuna processor in that country. TUNY tuna is sold widely in Mexico and has appeared in one store in San Diego, California. TUNY has repeatedly refused to sign a Dolphin Safe tuna policy with Earth Island Institute.

TUNY tuna is caught by chasing and netting dolphins, in order to catch the tuna which swim beneath. More than 7 million dolphins have died due to tuna fishing using this method. Some TUNY tuna labels DO NOT have a “Dolphin Safe” (“Amigo del Delfin”) logo, and this tuna is technically LEGAL to sell in the US. Other cans of TUNY tuna DO have an “Amigo del Delfin” logo on the cans. Since the tuna is caught by chasing and netting dolphins, it does not qualify for a Dolphin Safe logo under US law, and its sale in this country is therefore ILLEGAL. Mexico has no laws on labeling tuna, so the label is grossly misleading to Mexican consumers. We are concerned that supplies of TUNY tuna, both legal and illegal, may appear in stores around the US.

(1) Alert Earth Island:

If you see “TUNY” brand canned tuna for sale in the U.S., please contact Earth Island Institute with the NAME and ADDRESS of the store where it is for sale and the DATE. (See contact information below.) If you can, purchase a can and send the can or the label alone to Earth Island, with your receipt showing name and address of the store and the date.

(2) Talk to the Store Owner or Manager:

You can tell them that TUNY tuna is caught by methods that harm and kill thousands of dolphins annually. They should take it off their shelves and not sell it. The store owners are unlikely to get in trouble with law enforcement if they remove the tuna from their store shelves. (Keep in mind that SOME TUNY tuna cans, if they lack a Dolphin Safe label, are legal to sell in the US. But just because they are legal does not mean that they are good for dolphins – quite the contrary. Urge store owners or managers to remove all TUNY tuna and cease selling it to consumers.) If you can, please get the NAME and ADDRESS of the distributor who sold the tuna to the market or store.

If the store owners or managers are interested in selling true Dolphin Safe tuna in their stores, you can direct them to this website, which includes listings of more than 300 tuna companies that catch and process tuna without chasing, netting or harming dolphins:
