I like to fish for Opah how about you?
Hey, how about that.  Me too!  There are only a few good spots that I know to catch that Lampris!
I have heard those are very tasty
There was an extinct species of Opah called Turkmenidae, from central Asia.  They were a little bit smaller though.
What do you know about Opahs?
Other than that they are a prize for deep-water anglers because they are so large.  They are great for stuffing and mounting on your wall!
I dont know if I would want to mount one but I would love to eat it!
Well they are becoming more and more popular in markets so you may see one at your local grocery store!
Are they a expensive fish?
Opahs are frequently caught as bycatch in many longline tuna fisheries. Opah is becoming increasingly popular in seafood markets. It first became popular as a sushi and sashimi in the late 1980s and early 1990s. The meat is lightly flavored and lends itself well to a variety of preparations, principally sauté. Opah flesh has a light-pink to orange color, but turns white when cooked. It is popular in Hawaii, especially in restaurants. An average of 35% of an opah's weight is consumable, with the remaining 65
to a circumglobal distribution in the Southern Ocean, with the 34°S as its northern limit. Two additional species, one in the genus "Lampris" and the other in the monotypic "Megalampris", are only known from fossil remains. The extinct family, Turkmenidae, from the Paleogene of Central Asia, is closely related, though much smaller.
Opah specimens are rarely caught by recreational anglers. They are prized trophies for deep-water anglers as their large size and attractive form lend themselves well to taxidermy.
