Mortality for fingerling to 7" "eyes" is low in a new pond with ample forage. Once a mixed size population of "eyes" exists, expect 50%-25% survival of stocked fingerlings. Survival could be as low as 10% for fingerlings. Survival rate will be dependent on amount of weed cover, amount of proper sized forage fish and if LMB are present. IMO Walleyes and LMB are not a good combination.
