Greenseas Tuna may be more sustainable than some other tuna brands, but they still fish with FADs and nets that catch turtles, sharks and other creatures that are discarded as unwanted bycatch. Calling a product that does nothing more for the planet than remove ocean life "green" is quite a marketing stretch.

Greenpeace have recently rated Tuna brands and put out a comparison guide. Alternatively, you could not eat over fished fish out of tiny little metal cans that require high energy to manufacture and are largely thrown into land fill.

Greenpeace report on Greenseas Tuna:

Bycatch and fishing methods
Greenseas Skipjack Tuna is caught by FADs and purse seine nets that can trap and kill unwanted animals like turtles and sharks.

Commitment to sourcing sustainable tuna
Greenseas only use Skipjack Tuna from the Western and Central Pacific Ocean. Greenseas’ commitment to improving this Pacific fishery includes contributions to researching tuna sustainability in the region. Greenseas claim to be working toward an internal sustainable seafood procurement policy.

Traceability and labelling
Greenseas will label their complete range with ‘Skipjack Tuna’ by March 2010. To date there is no mention of the use of FADs on its website. Greenseas can trace its product to the vessel and can assure consumers it does not source from black listed vessels.

Support for marine reserves and equitable fishing
Greenseas is yet to ask its suppliers to avoid sourcing from proposed marine reserves or express public support for their establishment. No information has been provided on attempts to ensure their suppliers make a fair deal with the coastal states whose resources it exploits.

Verdict
Greenseas uses sustainable Skipjack Tuna and is improving its labelling. As leaders on sustainability we hope it will provide consumers with a sustainable pole and line caught tuna range to avoid unnecessary bycatch.
