Yes bluegill have begun spawning although no sign of fry yet.
Went out again today and happened to see some fatheads however were very large. Haven’t seen them spawning yet but maybe they have…?
Yes I see a good thousand bluegill every time I’m at the shoreline but only a few fatheads. There are no predators as pond is brand new and bluegill population is off the charts. Do have a turtle not sure if they chow on fatheads but is a possibility.
As to the structure we have a good 7 very large cedar trees in tbe pond as well as rock piles.
Thought bluegills were predators, though limited by small mouth size. Wonder if they eat the fatheads? I know from sad experience that tilapia sure will, especially when there's not much algae for them to consume.
