White perch - as bad as they say they are in different states?
Recently I've been catching more white perch and larger whites than anytime in the last 10 years in my local crappie/bass/pickerel lake. I did some research to find out why all of a sudden this species became so numerous and in sizes ranging from 3.5"-10". What I found was disturbing!
According to different state agencies, white perch can be detrimental to local fish populations - even their own - for the following reasons:
Pirmary food - eggs of all species
Secondary food - fingerlings of all species and shiners that comprise a significant source of multi-specie diets.
Prolific in that females can lay anywhere from 20,000 to 300,000 eggs which are fertilized by many males.
Overpopulation equates to small fish of all species at first and then the destruction of the young of certain species such as walleye and bass, even though small white perch also make up a part of their food source.
In Kansas, the law states that all white perch caught must be kept and disposed of. Other states encourage non-release, though it is expected that most small perch not worth cleaning will go back.
White perch are not real perch but related to white bass and can dilute the white bass gene pool by crossbreeding - another reason to kill them.
I'll be making a presentation to my fishing club to have white perch tournaments to help the fishery, but knowing how little interest bass and pickerel anglers have for catching panfish, I doubt they will see the danger until it is too late. As of this year, yellow perch catches are way down but crappie are still doing well - numbers and size. That could change. I've taken out over 400 small perch in the last two months to feed the bass in my pond, not caring about the spawns of the five species in it. That won't even put a dent in the w.p. population.
