Bob thanks for taking the time asking around and sharing responses. Great read. Seems like the best way to determine as one person pointed out and is part of the link I posted earlier is the inside roof of the mouth. LL has a single row what they call vomerine on the roof of their mouth, brown trout has two in a more zig zag pattern. Too late for that comparison unfortunately. Again I hope to attend the F&G meeting this Saturday, will see if any biologists are available and I'll post their opinions.
