As of Mar 12, I still had 80% ice cover, although it is now thin and melting fairly quickly. My ice forms later and leaves later compared to other nearby ponds that are exposed to more wind action. Water around the dock and fish cages was open. I dropped hydrated, rolled pellets into the perch cages and they did eat pellets. Thus I assume no YP deaths due to low DO this winter. I did loose the 4 RES that were in a cage for 3 yrs. I think the low winter DO of 2 mg/L was too low for them becasue those 4 RES survived previous winters in that cage.
