Pond Boss Forums MANAGING AN EXISTING POND Evaluating and adjusting fish populations SMB / YP / RES - Now what?

I am not in the Lake Erie watershed, I'm in central Ohio.

My understanding of GSH spawning substrate is grasses... correct?

While I do not have grass I do have good size patches of Chara, is this a supportive substrate for GSH?

I will say that my FHM have reproduced like rabbits... clouds of FHM the summer they were in the pond without predators. So far they are still going strong, but it's obvious that their numbers are fewer now that predators have been introduced. I suspect that the Chara beds may be assisting in continued FHM recruitment?
