I have read that back in 19oatcake people used to use burning torches to attract fish at night, spearing them when they came to investigate the light above the water.
You have to have a license to fish with a rod here as well. I think the difference is that we have (in most, if not all, states) a category of fish called "rough" or "non-game" fish. This includes such fish as carp, suckers, redhorse, shad, etc. These fish are not protected as they are considered a nuisance. Since they are "non-game" they are outside of almost all protection. Therefore, spearing these fish is legal. Generally no license is required for anything that is listed as non-game.
Do you have no "nuisance" or "rough" fish that fall outside of your game laws?
After carp were introduced to the U.S. from Europe, they proliferated in many rivers and to a great extent pushed other, more desirable fish out. American anglers tend to hate them, although there are a handful of people that like them. Personally, I find them too "bony" to bother with.
Just as a word of caution. I'm certain that spear fishing in fresh water is against the law in the UK.
I know that in many US states the carp is regarded as a pest fish, in fact there are places where it is illegal to return a caught carp to the water alive, but you get spotted spearing carp in the UK and not only will you very quickly find yourself dealing with the Law, you'll probably do so whilst being treated for the injuries incurred when the local anglers 'arrested' you.

According to this guy i saw on tele the best way to spear fish is to free fall from an aeroplane land on the fish stunning it then bite its head off and eat the guts, cant for the life of me remember his name. Mear grylls i think.
