GSH are very prolific, fast, and I believe very good at thinning down newly hatched fry. Larger GSH will will be very competitive with your other fish of similar gape size.
Interesting indeed. I had looked into stocking them in my catfish/carp pond to control carp reproduction. But with there being no vegetative growth at all in that pond, I didn't think they would survive. Right now my plan is to thin RES with rod and reel and throw the excess into my catfish/carp pond. My SMB I have plenty of takers for to throw into their ponds. But if I struggle to keep up, I may stock GSH. Do we have a good source locally?
