Pond Boss Forums MANAGING AN EXISTING POND Evaluating and adjusting fish populations GSF

Bill, I saw that in a clients pond. He stocked YP/RES/FHM/GSH and let them stew for almost 2 years before wanting to add SMB. I did a survey in the pond before we stocked SMB and found no recruitment from those species due to some GSF that were in the wet spot in the woods that he turned into a pond. Another area that was turned into a pond of the same size, at the same time, and stocked with the same fish showed a lot of recruitment. The difference between the 2 ponds? No GSF.

The pond with GSF was drained 90% and nuked with Rotenone.
