If it is true, Theo, that GSH spawn only once a year, North or South, they are doomed in a Southern LMB pond and pretty much a waste of money except for the initial stocking boost. There are far more efficient means of generating and re-generating the needed forage...that would be my "prattle of those East of the Trinity" as DD1 referred to it and since it comes from East of the Trinity, should not be taken seriously.
