Most sterile fish breeds still spawn.. just unsuccessfully... shooting blanks so to speak. Saugeyes, wipers, tiger muskie, etc. develop eggs and go through the motions of spawning but the eggs and sperm are not viable.
Where do you live? If you live down south, there is a good chance they won't do any spawn ritual if your water does not get cold. Pike spawn at 35-38 deg water temp, muskie at 55-60... I have no clue what a tiger muskie would do or when it would do it.
But your local fisheries biologist working for your dnr would be able to tell you all the info you need.
