One of the best parts of fishing our river is you never know what you’re going to pull out of it. In the old days, this comment would elicit some snark about a “really brown trout,” haha. But today, we discuss what in the heck are these crazy bass that Roland Trevino pulled from one section?
Take a look at his pics and see how white the sides are.
Rosi Dagit, Senior Conservation Biologist and Certified Arborist for the Resource Conservation District of the Santa Monica Mountains, agreed that they were “strange-looking bass” because “the white-side blotches are quite noticeable” in the pics we showed her.
She enlisted the help of Camm Swift, emeritus PhD from the Natural History Museum of Los Angeles.
“These appear to be very faded out largemouth bass, but it would be good to see both dorsal fins elevated. Maybe they came from fairly turbid water,or were held in a white bucket for a time and lost lots of color?” he wrote in an email to Dagit. “There is a slight possibility they are white bass or white perch, Morone chrysops or M. americanus, but they have much larger anal fin spines than largemouth bass and do not appear to be present in these fish.
“Both of these species are from the eastern United States (as are largemouth bass for that matter!) and the white bass is known from a few places in central California but unlikely in L. A. Thus, without some other convincing evidence I would call them largemouth bass.”

Wow interesting it might be another species!! jane
I thought if the head and tail curl toward you and they sing, it’s a bigmouth bass.
LMB is my vote. I have seen so many color variations that, honestly, I would never have even considered it anything else. Should you get more details, do let us know Jim. For example: Spotted Bass? The thought that it is a “White Bass” (Morone chrysops) is crazy. Caught a lot of those over the last year while visiting Texas. This is def. not one of those.
Excellent to know, Bernard. Thanks for the intel!
Hi there, it looks like a white perch. Here is some info on identification.
