we don't eat it in Queensland mainly because it is ranked as one of the highest ciguatera risk fish and we are blessed with quality anyway
but I do know guys who have eaten it and say it could fall among the mackerals as a table fish
slice it in 6-8mm slabs dust with peppered flour and shallow fry till light brown each side squeeze a bit of lemon on it
if it doesn't taste good use the rest as bait
