Thanks for the info Bob. Are golden shiners a schooling fish? Also...relating to threadfins, what is the average temperature of a pond during winter in my area...Southwestern Virginia? I know most ponds freeze over here, but normally it isn't over the entire winter. I know lakes nearby support both the threadfin and the alewife. So is it a matter of how deep the pond is? If so, how deep would it have to be in order to maintain these....

Also along with this list of questions, you mentioned each have their own role in pond management....what are those roles?
