Sorry,I have not responded sooner.The paddlefish are a mystery. Never seen in my pond.I assumed that I would need to fertilize more often as they are filter feeders but that has not been the case. .I,m going to try to have it shocked in hopes of bringing a few up to the surface to assess their growth/condition. I,ve heard I may have to sign a release in case any die.I,m willing to lose some. Besides.I can always cook them.I.ll get that supplier,s name as soon as I can.
