huntwriter, the taste of particular fish species is culturally dependent. Northern pikeminnow in fact, as you have mentioned, has fine white flesh that is perfectly edible and has its own unique flavour. There are two factors that draw people away from eating these. One is that we are spoiled with the availability of pacific salmon in this part of the world (our obsession/addiction to them will be or is driving them to extinction). The second one, as you have mentioned, the amount of fine bones in a northern pikeminnow. Those who grow up in an Asian background such as my parents do not mind eating northern pikeminnow, because these fish are relatives of what are commercially available in Asia (common carp, grass carp, etc). My parents used to make them into soup, while I have friends who prefer to make them into fish cakes by grinding both the flesh and fine bones.
Also, I just like to point out one thing.
It is not a good idea to retain a fish for eating when it is not identified for several reasons. One is that it might not be legal to retain it. Although it is not salmon, trout or sturgeon, there are in fact species in the minnow family that are protected in British Columbia. Native exclusively in the Fraser Valley, salish suckers are highly endangered. Although a salish sucker and a northern pikeminnow have distinct features that set them apart, their bodies look almost identical with one quick glance. Second is that eating an unknown species can be dangerous. One should find out what it is and whether it is edible or not before consuming.
poper, don't taste a dumpster.
Some folks think bass taste like dogfood and I happen to like them too and so are many others.
Love eating smallmouth bass, as long as they are kept early in the season before they retain the muddy taste, which is the same with rainbow trout in lakes.
