Tuna is widely available, but can sometimes see a dip in availability due to the monsoon season and where the tuna has been landed. Various types of tuna – particularly yellowfin and skipjack tuna – are also used for the canning industry.
Serious sustainability issues surround this fish, particularly when whole shoals are caught using large nets (such as with the purse-seining method). It is widely agreed that albacore tuna caught by pole is the best option as these fish are landed individually. Bluefin tuna - the most prized and the most vulnerable - should be avoided. Skipjack tuna, used in tinned tuna is the most sustainable of all the tuna species.
