Hawaiian Fish you Need to try


The ocean surrounding Kauai is a natural playground for sea creatures big and small. It’s not uncommon to find a monk seal sunbathing on the sand, spinner dolphins twirling offshore, or green sea turtles peeping their heads above water. Underwater, Kauai’s reef system is a labyrinth of coral reefs, sea anemones, sea urchins and a rainbow of reef fish swimming about.

Out in the deep blue Pacific Ocean lives some of the tastiest fish around. Here are some of the most delicious fish that must be tried while visiting Kauai:



Opah Kauai fish

Commonly known as moonfish, Opah was once thought to bring good luck by fishermen and was not sold, but given away. Opah is one of the most popular fish in restaurants for its lightly flavored white flesh that is rich with healthy fish oils and can be prepared a variety of ways.




Ono fish on kauai

The name speaks for itself, Ono is the Hawaiian word for good to eat. The Ono, or wahoo, is a close relative of the king mackerel. Ono is a lean fish that’s juicy and mild in flavor. You can’t go wrong with having ono served as a tempura style fish sandwich. Now that’s ono!




Onaga fish Kauai

Onaga, or long tail red snapper, has a soft, flakey flesh that makes it one of the most decadent Hawaiian fishes to enjoy. One of the best ways to enjoy onaga is steamed Chinese style with sizzling peanut oil poured over it.




Opakapaka Kauai

This fish is melt in your mouth delicious. Opakapaka or pink snapper is a soft, moist, delicate fish that can be prepared many ways, but is best served steamed.



Kauai Ahi Yellow Fin Tuna

In Hawaii, ahi is the ambiguous name for both the yellowfin tuna and the bigeye tuna.   Hawaiians use ahi to make poke – raw fish chunks marinated in salt, soy sauce, inamona, sesame oil, seaweed and chopped chili pepper. Many variations of ahi poke are available in local fish markets and grocery stores. It’s hearty steak like texture is perfect for fish tacos, seared on top of salad, or crusted in furikake (seaweed seasoning).

The Hawaiian Mahimahi, or dolphin fish, is one of the highest quality local fishes. Mahimahi has a firm, white flesh with mild flavor that tastes fantastic prepared just about every way.
