Feeding habits of bluenose warehou, Hyperoglyphe antarctica (Carmichael, 1819) (Centrolophidae) at seamounts of the Southern Atlantic.
Diet of bluenose warehou, Hyperoglyphe antarctica, was investigated from samples collected during commercial fishing (trawling and longlining) on seamounts in the Tristan da Cunha EEZ in the South Atlantic Ocean. Bluenose warehou (57–123 cm TL, N = 309) was found to forage on a broad range of prey,...
