I consider YP sort of dumb. That is normal behavior for some if not most to lie still on the bottom as soon as they are released. When they realize they are in open water then they swim off. I suspect most of the deaths that you had were due to fungus and improper handling somewhere between seining and release. As I mentioned the really reputable fish farms will replace early fish deaths (usu free). If they are smart they value your business and want repeat business and good references. Early cold water stocking can sometimes be 'iffy'. The fish place where you bought the YP and minnows, do they specialize in YP or handle numerous species?
