I’ve researched that quite a bit but can’t get a definitive answer. I believe it varies according to size with larger tiger Muskie needing cooler water than younger smaller tiger Muskie. From people I’ve talked to and according to State of Nebraska stocking plans pure strain Muskie tolerate warmer water than tiger. And I’m fairly certain there’s 0% chance you’d have to worry about reproduction. So that may be a better option. In fact it’s probably a better option for both of us. But I wanted to play around with TM for a few years before moving on to pure Muskie.
Side note: I did have a northern pike, the least warm water tolerant of the 3, survive up to 37” in my 2/3 acre pond. That pond does have a deeper section than my large pond, but it does make me hopeful that tiger Muskie can survive.
