Claim: Pacific and Atlantic bonito meat, which has a moderate fat content, is identifiable by its firm texture and dark color but may be marketed as tuna , which is a saltwater fish that belongs to the mackerel family, in other countries.
Evidence: Bonito may not, however, be marketed as tuna in all countries. The bonito has a moderate fat content. Pacific and Atlantic bonito meat has a firm texture and a darkish color. Bonitos are a tribe of medium-sized, ray-finned predatory fish in the family Scombridae – a family it shares with the mackerel, tuna, and Spanish mackerel tribes, and also the butterfly kingfish.
