Reekfish

Reekfish are large, red fish found in Zora's Domain. They have a horrible odor, and feed on coral. Yeto the Yeti constantly raided the domain to get reekfish, possibly having knowledge of their coral diet. To find Yeto, Link must record the scent of the fish by catching it with a piece of coral, specifically the Coral Earring given him by Prince Ralis, who apparently also knew of their feeding on coral. These fish are apparently very sacred to the Zora.

Reekfish are used by Yeto for Yeto's Soup. It should be noticed, however, that the ones used are about the size of a full grown human, unlike the ones typically caught by Link.

Behind the scenes
The Reekfish is based on an actual species of fish called the Sockeye salmon.
