This is the perfect fish for those who don't like fish - you can't taste it. Aside from being very bland, it is limp, eats low on the food chain, has little internal integrity, a weak stomach, and disintegrates entirely when exposed to heat. I'd propose it's name be changed to "Congress Fish" except for one discrepancy - it has a backbone.

Pan frying is not a good idea. Fillets dusted with rice flour and fried in very shallow oil, as I usually do, can be disastrous. When turned skin side down, the skin instantly becomes glue and sticks to the pan, even through a heavy dusting. Then, when you try to move it, it disintegrates. Perhaps frying can work if the fillet is heavily battered and deeper oil is used. I normally recommend against that method because you end up tasting only batter and oil, not fish. With this fish, though, that's all the flavor you'll get anyway.

Briefly poached, half fillets holds together well enough to carefully remove to a plate, but it's not easy to eat because it disintegrates when you touch it. All in all, I think McDonalds has the right idea - grind it up, mix it with plenty of binders and extenders, and use it for machine made "fish sticks".

Buying:   Fresh fish are often available in markets serving a Korean community. I suspect they use it to make fish balls or something like that. Dried pollock is very common in just about all Asian markets, but particularly Korean.. Frozen pollock fillets are widely available, even in regular supermarkets. It's very inexpensive and worth at least half that.

Scales:   This fish is incompletely covered with scales that are tiny and thin. They scrape off easily as a gray slush with no flying about.

Cleaning:   This fish is full of mushy stuff, and the belly is so weak it often breaks, spilling gooey guts all over the place. The body cavity extends well behind the vent. Gills pull out fairly easily, but the collar will probably pull apart when you do that - that's not a problem since you're either going to discard the whole head or break it apart anyway.

Fillet:   This fish is not real easy to fillet because it's bone / fin structure is discontinuous and not easy to follow, it's very limp which makes it clumsy to handle, and the flesh is soft and prone to fall apart. I've had the best success with this method:

1. Cut off the head.
2. Make a cut on each side of the ventral (bottom fins) and pull the fins out.
3. Make similar cuts on each side of the dorsal (top) fins and pull them out. This exposes the real bone structure so you can find it and follow it.
4. Set the fish on it's belly and cut down to the backbone on both sides. Then work across the backbone at the tail and work forward.
5. When you get to the rib cage, cut the ribs from the backbone with kitchen shears and pull them from the fillets with long nose pliers. They are short and very thin, but easy to locate in the soft flesh. There are also some centerline spines for the length of the body cavity which should be pulled out straight forward.
6. The front lower part of the skirt is coated with a jelly like substance. I make a diagonal cut leaving only the part with normal flesh attached to the fillet.

Yield:   A 1 pound 4 ounce fish yielded 9-1/4 ounces of skin-on fillet (46%) and 8-5/8 ounces skin-off (43%).

Skin:   The skin has very moderate shrink, but quickly turns to sticky goo when heated. It does have a somewhat stronger taste than the flesh, you can actually taste it. Raw skin is quite tough, and the flesh very tender, so it's easy to skin with no flesh lost (Method).

Stock:   The head, bones and fins, simmered slowly for 30 to 40 minutes, make a stock serviceable stock with inoffensive flavor and almost no oil.
