I recently stocked 3 ponds with crawfish. The crawfish did well in 2 of the ponds and are all dead in the 3rd. The 3rd pond, where they died, has BG, Tilapia, RES, LMB fingerlings, FHM and mosquito fish. I also noticed the eel grass I planted is not doing well. I am suspicious it’s my water quality but not sure why it would kill the crawfish and turtle first. One of the other ponds i added crawfish to is on the same property and they are doing well. Any thoughts appreciated.
