Preliminary studies of age and growth of bigeye
tuna (Thunnus obesus) in the western Indian Ocean.
THE FIRST major effort to limit the overexploitation of western and central Pacific yellowfin and bigeye
tuna stocks has been made.
For the tuna royal slam, Zyg caught a longtail in Pakistan, a 30lb skipjack and 121lb dogtooth in Mauritius, a 10lb blackfin in Florida, a 40lb bigeye
on the Galapagos Islands, an 80lb yellowfin off Ascension Island, a 50lb northern bluefin in Massachusetts and a 187lb southern bluefin in Tasmania.
Avoid bluefin and bigeye
tuna (also sold as "ahi").
Together, the seven principal market species--albacore, Atlantic bluefin, bigeye
, Pacific bluefin, skipjack, southern bluefin and yellowfin--are the single most important resource exploited on the high seas, accounting for over seven percent of total marine capture fisheries production and 11 percent of the total value offish for consumption.
Fishing is an important source of revenue for some of the smaller island nations, but the declaration recognized over-fishing had jeopardized local stock levels of bigeye
and yellowfin tuna.
Apart from divers metres below us, we had the reefs to ourselves and spotted clownfish - yes, we found Nemo - mournful-looking bigeye
trevally, coral groupers (orange with blue spots - very paint-by-numbers), haughty, yellow and blue-striped emperor angelfish and literally hundreds of (apparently harmless) jellyfish.
, skipjack, yellowfin, and abalcore enjoy large and growing markets, but bluefin, which can reach three meters and weight over 650 kilograms, still has the most appeal.
The 2ft 6ins Bigeye
tuna, weighing 12lbs 8oz, was netted by a trawler looking for bass.
TUNA were about 2 times as heavy (and 8 times more abundant) in the 1950s.
Since the publication of the first edition of the Good Fish Guide, Marks & Spencer has removed swordfish, Atlantic halibut, monkfish, thornback ray and bigeye
tuna from its shelves.
chub (Hybopsis amblops) is a-rare, intolerant fish species in Ohio inhabiting riffles and shallow runs in small to mid-size streams.
