Hi Steve, The pond is under construction at this time and will be a 60x60x6ft deep to raise the fry. I will be using a drilled well to top the pond off every day and will be filling with city water to start, I plan on putting a large pump in the middle of the pond surrounded by a large very fine mesh net to keep fry form being sucked into pump. Will lime the pond to start out with to kill any bad bacteria and will ferterlize using liquid fert. I will start this process about two weeks before I get ready to release the fry. I will be using a large pool to spawn and hatch my koi and after 4 days will put in mud pond. I plan on keeping the top of the pond covered with a good net to keep out birds and other things like turtles and large animals like deer as we have alot of them. Blue herons are kind of bad around here to so I am going to do what it takes to keep them out.
Sound like you are very knowledgable in this field and I am gald to be corresponding with you. If you think this method will not work with the way I plan on doing the pump I will be open to any ideas and other info that you may have to share.
