Cecil I appreciate the offer, if you don't have a use for them I would be glad to get them. Do you know how long it takes for newborn sunfish to use up their yolk sac?

Eric thanks for the idea, I have plenty of trout pellets if I need to crush some for the fry.

Scruffy my big pond has plenty of PS's that reproduce, but I kept the 10 largest ones in the RAS over the winter and now hope to get offspring from them and select the fastest growing ones, maybe a bigger PS down the road.
Hopefully your pond will keep enough water so all the fish survive, but if the worst happens have you decided to try sealing the ledge with cement?
