Oscar
Astronotus ocellatus
A large South American cichlid introduced to Hawai'i and now established in island reservoirs, the oscar is a hard-fighting, aggressive gamefish popular with freshwater anglers. It has a deep, oval, laterally compressed body colored charcoal to olive and heavily marbled with rusty-orange blotches, long-based dorsal and anal fins, and a distinctive eyespot (ocellus) at the base of the tail — a black spot ringed in bright orange-red. In the Wahiawā Public Fishing Area the oscar carries a daily bag limit of one.
Warm, weedy, low-flow reservoirs and irrigation impoundments on the main Hawaiian islands.

Recorded Waters for Oscar
FishFinder links Oscar to water records in Hawaii. These associations may reflect documented presence, seasonal runs, or historical stocking, not angler catch reports or current abundance. Read the linked water guides and source notes for evidence dates and reaches.
Oscar Fishing Regulations & Limits
A recorded association does not establish that targeting or retaining Oscar is permitted. Confirm current species protections, seasonal and emergency closures, reach-specific rules, gear restrictions, bag and size limits with the responsible fisheries authority before fishing. A fishing license does not override these restrictions. FishFinder's regulation records may be incomplete; missing rules do not mean unrestricted fishing.

Equipment planning for Oscar
We have not selected a species-specific affiliate setup for this guide. First establish whether targeting is permitted at your destination; no tackle recommendation should be inferred from a species record.
Equipment guidance is not permission to fish. Confirm the exact water, date, species, method and current official rules first. A closed season prohibits targeting, even with release. Recorded fish presence does not establish an open fishery.
- Check permitted methods, bait and hook restrictions before choosing tackle. Match rod, line and lure ratings to the lawful method and conditions, rather than buying by species name alone.
- Plan weather protection, drinking water and a way to call for help. For boat trips, confirm required flotation and safety equipment with the responsible boating authority.
- Read the habitat and water-specific source notes in this guide, then confirm an appropriate lawful method with the local fisheries authority before choosing equipment. Do not assume a general freshwater combo suits every species or water.
This is an editorial planning checklist, not hands-on product testing. Use equipment you already own when suitable. The gear directory contains affiliate links; any product suggestions below have their own disclosure. Retailer region, availability and Canadian shipping are not guaranteed.
