I am in NE Oklahoma but probably still have right at 3 months depending on any cold snap. I think I had a few left back in December last year that I would have like to net up or snag, they were pretty sluggish.
I may start to take some out if they continue to bite that easy and get a little larger. I had never caught them from this pond before but I added about 3x as many this year because they were smaller fish when we go them. I am sure they have spawned in the pond but I doubt I will ever confirm since the water is pretty turbid and most of them will get eaten before they get to any size I could prove to be certain it was a spawn.
The pond my dad put some in is much more clear but still has plenty of algae for them to eat. When we fished out there the other day there was a large one in there that had to be 2-3 pounds, just cruising around the bank and pecking at the brush in the pond. I wish I could have taken some video of it.
