Just as an FYI - for the vast majority of the USA, most (perhaps all) freshwater fish are basically toxic. Don't count on fish for LTS, just short-term. The levels of mercury, PCB's and the like in fish is dangerously high. PREGANT WOMEN SHOULD NEVER NEVER EVER EAT FISH CAUGHT IN THE WILD!

Here's some references:

"PCB's found in Morewood Lake, Massachusetts. Fish from a small lake at the Country Club of Pittsfield in Massachusetts have been found to be contaminated with PCBs. The state Department of Environmental Protection (DEP) said the fish taken from Morewood Lake have the same level of contamination as those found in the Housatonic River, which is heavily polluted with PCBs from the General Electric plant. The state is now considering an advisory warning people not to eat any fish caught there. A spokeswoman for the state agency said it appears that Housatonic fish have been migrating into Morewood Lake through a culvert that floods when the river is high."
