Since I USED to get lobsters for $6 each, I've done something similar, but they called it Poor Man"s Shrimp, and you use bluegills instead of buying cod.
Fillet the bluegills
Throw 'em in a bowl with whatever spices you like and roll them around. (I used Old Bay)
Roll the fillets up and hold them with a toothpick through them
Drop them in a boiling pot of Mountain Dew (They'll turn a yellowish green)
When they float, drop them in iced water to cool quick. Use a couple bowls of iced water if you have a lot.
Sprinkle a little more Old Bay on the outside and eat them with your favorite cocktail sauce cold.
