Does it exist?

Various fish species from elsewhere in the world have been deliberately or accidentally introduced to Hawai‘i. High-quality game fishes such as largemouth bass, tucunare and channel catfish are now widespread and well established in reservoir waters. Two game fishes, rainbow trout on Kaua‘i and smallmouth bass on O‘ahu and Kaua‘i, may be found in both streams and reservoirs. Panfish such as bluegill and tilapia are generally abundant in reservoirs statewide, and several tilapia species also occupy stream habitats.

Tucunare are peacock bass. Had to look that one up.

I believe Jay Yelas was born in Hawaii and caught bass there.

I believe they have some smallmouth as well as some peacocks there too.

You can catch Peacock on Oahu...not sure about smallmouth.

Yes, on Oahu mostly. There is one decent-sized lake in the central valley that allows boats. There is good fly fishing as well!

In the times I've been, I have been limited to catching in the brackish canal from my uncle's place, but seriously considered renting a boat and hitting Lake Wilson during my last trip.
