How long do blue gill spawn and how many times a year? I have holes all dug through my pond everywhere from them this is the first year I have reaally seen this it is neat to watch them. There are a couple close to my house that have neen there since the first of june and they just keep going. We catch them put them back and they come right back to the back sometimes I can reach down and touch them with my hand they act like they just dont care then swim off. I know they could be different ones as the weeks go buy but I just wondering if anyone knew anything about there spawning habits.
