Hooked on tuna: People have been harvesting these ocean predators for 44,000 years

Tuna has been a valuable food source for humans for at least 44,000 years, according to a new study that analyzed fish remains found in archaeological sites around the world.

The study, published in the journal Nature Communications, found that tuna fishing was an important part of the diet of early human populations in coastal regions.

The global tuna industry is now worth around $40 billion annually, but overfishing and climate change are threatening tuna populations and the livelihoods of those who depend on them.
