i hear ya,you can figure unculled 700-800..these are a little lager then other spots that have small ones 800-1000 per G.. used to sell em the bait shops they held them as long as two weeks in thier tanks
i belive maybe longer if the waters r cool. uncle keeps em in the lake pened for almost a mounth about two to three gallon at a time,
i used to get em rigth near you in collingwood. theres a spot
[**edited**} where the water goes under the road
where i show phil there must had been a 1000 gallon well maybe 999
you have to clean out the dead ones all most every day to stop desiceses
