IMO the hybrid trout like Splake and Tiger Trout are more durable than "regular" trout. How do I know?? Fall 2018 I stocked Brookies and Splake. I failed to keep a hole open all winter and DO got very low. The following spring only the Splake were left. Maybe it has something to do with hybrid vigor. If it were me I would try Tigers and/or Splake.
