Tuna

This valuable fish thrives in the warm waters of the Indian Ocean, which is home to more than 20 per cent of the world’s tuna stocks. There are three main types: yellowfin tuna, bigeye tuna and albacore, and all are intensively fished, predominately for export in canned form. The rich, meaty flesh is perhaps best appreciated when simply grilled on a barbecue and lightly seasoned, but it is also used in curries and stews.
