Except they are tilapia beds, the bass spawning activity is very minimal at best. Interestingly, the spawning habits of tilapia is quite aggressive. The beds are dug out, almost to 6 or 7 inches into the lake bottom.
The tilapia are very quick to chase off bed-raiding shad and mullet, and many are wounded or beat up from numerous battles protecting their nest.
Timing wise and in many instances, the bass will spawn alongside the tilapia. So, I guess you could assume there are bedded bass nearby. Or they’re at least moving in to begin the spawning ritual in the very near future.
Here are a few tilapia beds near Lake George.
