Tuna
Why is it on the Redist?   Biology

1. Yellowfin tuna stocks in all oceans are at unsustainably low levels and fishing rates continue to be too high.

2. Yellowfin tuna was listed as “Near Threatened” globally on the IUCN Red List of Threatened Species in 2011.

3. When yellowfin tuna are caught with longlines, thousands of other species are caught and discarded, including endangered species of sea turtles, seabirds, and sharks. Yellowfin fisheries that use purse seine employing fish aggregating devices (FADs) lead to bycatch of other species including juvenile bigeye tuna (IUCN  Vulnerable), threatened sharks, and other marine life.

Yellowfin tuna can grow to be 200 kilograms (440 pounds).

Yellowfin tend to stay in the top 100m of the ocean, but can be found as deep as 200m.

Yellowfin are highly migratory and travel in schools of similarly-sized fish including other types of tuna, as well as dolphins, whales, sharks and porpoises.
