White Perch or White Bass?

Caught these a few years ago. I thought they were White Perch, but not sure now. I thought White Bass have like a faint purple hue on the underside fins, from the ones I caught in the past. These had no purple hue.

Now that's interesting.

You answered your own question, but 100% white perch. Perch have that very obvious lateral line and really nothing else resembling a stripe. White bass are also considerably larger. According to the ROM book, an average size white bass in Ontario (11") would be near the record white perch size for the province (11.4"). White perch average just over 6".

White perch, that's cool. I would have just guessed that they were silver bass. Thanks for sharing that, learning something new.

Thank-you for the confirmation.

These three were the first and only white perch I ever caught.

So I can tick that species off my list.

Yes, 100% white perch.

Where did you get your information on average size and record white perch? What is the ROM Book?

I fish the eastern side of Georgian Bay in the fall every year and the white perch are annoying while we're walleye fishing. We catch a ton of them and they are all 9 to 12". The record cannot be 11.4"

12" white perch are common in the great lakes.

Yes, 100% white perch.

The ROM Field Guide to Freshwater Fishes of Ontario is the book. There is a new revised edition out which I don't have (yet) so some things may be updated.

boy they are so close, comparing my post of Fathers day and these you can see mine has more lateral lines so white bass for mine and white perch for yours. Neither of these look like silver bass. But I have always called mine white perch but have changed my saying now.

White Bass and Silver Bass are the same species. Silver Bass is a common nickname.

I think the fuss here is about White perch (Morone Amerivana) Vs White Bass (Morone Chrysops). According to Wiki they are different species.

But my guess is that they are rather subspecies with numbers of intermediate forms in local areas and may interbreed as well.
But that’s not what I would firmly stand for.

Yes white perch and silver bass are a different species. They may be related in the same genius but they are a different species. Same as walleye and perch are in the same family but are different species. ??

IMO this is Rudd. Invading Species from Europe. lots of them in Hamilton area

Well, Walleye and Perch belong to the same Family but to the different Genus.
Walleye: Family:Percidae, Genus:Sander, Species: S. vitreus
Yellow Perch: Family: Percidae, Genus:Perca, Species: P. flavescens
I don’t know much (or rather anything) about White Perch Vs White Bass but I do know that for Cisco it is sometimes very difficult to determine what exact species the particular specimen belongs to.
For example Wiki article for Cisco indicates 6 presently living species of cisco in Great Lakes but also mentions that:
Usually, several taxa of ciscoes are found in a single lake. They exhibit different habitat distributions, feeding and breeding habits and morphological adaptations e.g. in their gill raker numbers. In the Great Lakes, at least five ciscoes coexist.[3]
According to genetic analyses, these cisco types do not represent unique, separate evolutionary lineages, but similar cisco morphs have evolved and attained their specific characteristics largely independently in each lake. Therefore, it has been suggested that they should not be recognized formally as distinct taxa, but all considered members of a single species, Coregonus artedi (sensu lato)] or Coregonus artedi complex.
Again I have no idea about White Perch vs White Bass but suspect that situation might be similar. Or not so…
