How good is your tuna? The tuna in your sandwich or on your spaghetti? The intrinsic quality
of the fish is important, as is its species
(see above), but the method adopted for fishing
, and the later processing, must also be factored in.
Unfortunately most of the tuna on sale is fished using techniques of a totally unsustainable nature, such as use of longlines
(also known as boulters
) and FAD
(Fish Aggregation Devices), destructive
in their impact
on the marine ecosystem. FAD are floating structures that exploit forms placed underwater to attract tuna and other fish, then caught in nets called seines, but which also lead to a bycatch: too many young tunas, as well as barely sellable fish, and even protected species such as turtles, dolphins, devil fish and sharks. The latter species are thrown back into the water, having died in the meantime.
for tuna fishing − acknowledged as such by Greenpeace itself − are traditional angling
and use of the seine but without FAD
, which must trap only the schools of the species in question, without damaging the seabed. Processing
is also crucial. How long does it take to get to the canning plant from the harbor? How are the fish cleaned, cut, prepared and canned? Canned tuna products are definitely not all the same!
