It's been proven perch have no issues with reproduction. The problem more often then not is is an overabundent supply of large predators, and extremely high fishing pressure. One cannot support the other wich ends with low fish populations. Better management is needed to fix the problem. Some lakes need high pressure on perch to keep population in check and others need higher pressure on predatory fish. Unfortunately this isn't how it's being managed in many cases
