Get Involved by Donating Your Fish
Poseidon Fisheries Research is looking to fill the gaps of missing life history information for Hawaii’s coral reef species. We’re working with fish markets and fishers to collect length, weight, age, growth, and maturity information for these local species.
We’ll gladly accept any fish species pictured below and will return your cleaned catch to you after we collect the necessary samples for our study.
Hawaii actually has 5 different species of nenue!! We are currently conducting full life history workups for each. They often school in shallow rocky areas close to the surge.

Description: Most have a drab gray body while some may be two-toned alternating dark and light gray, spotted white, striped bronze, or even take a pure yellow morph which Hawaiians referred to as the “queen nenue.”
The umaumalei is a common species found on our reefs here in Hawaii. While it is a unicornfish, the umaumalei does not have the distinct horn on its head like other members of its genus. The sharp spines near the base of its tail are a trait it shares with all other members of the surgeonfish family and are used as a defense against predators. These spines are incredibly sharp so be cautious when handling this fish.
