Claim: Pacific and Atlantic bonito meat, which has a moderate fat content, firm texture and dark color, may be sold in other countries as tuna, a kind of fish which belongs to the mackerel family.
Evidence: Pacific and Atlantic bonito meat has a firm texture and a darkish color. The bonito has a moderate fat content. The meat of young or small bonito can be of lighter color, close to that of skipjack tuna, and is sometimes used as a cheaper substitute for skipjack, especially for canning purposes, and occasionally in the production of cheaper varieties of katsuobushi that are sold as bonito flakes. A tuna (also called ) is a saltwater fish that belongs to the tribe Thunnini, a subgrouping of the Scombridae (mackerel) family.
