Fun Facts: Bluefin tuna could be the most inefficient protein that a human can eat. This fish needs to eat 15 lbs of other fish to produce 1 lb of tuna at the market, and these fish are typically carnivorous fish that have eaten a ton of herbivores that have eaten tons of plants and autotrophs. By contrast, a chicken takes about 2 lbs of vegetable matter to make 1 lb of meat.
