TAMU says 1 y.o. LMB that are up to 10" in length can spawn in Texas.
I don't know about the Tiger Bass hybrids in particular. However, if you have lots of forage they should really put on the weight their first year.
I would guess (total non-expert) that you should get at least some spawning next spring.
Maybe plan for that contingency for your management plans? If you don't see any YOY bass, then go to Plan B.
Are the tigers the only LMB in your pond?
