your all over looking one thing hybrid stripers do not spawn they go through the ritual but it doesnt happen I live by lake wallenpalpac stripers were stocked in the 80s and 90s the hybrids and the real stripers for that matter do not spawn now im not sure but I dont think they would spawn in ontario because of the fresh water the salmon replenish them selfs once the stipers r caught they won replenish them selfs
