Ok all you fish biologists.

42 posts in this topic

So just recently, Eagle Eye Aanderud has been noticing some strange beings that are on the Flatheads we’ve been catching. For all I know they have been there all along and just lately started noticing them.

At any rate the thing is about the size of a fish scale, is clear, gelatin like and sort of looks like a very tiny jellyfish or ray. If you look closely, you can see the thing swimming around on the surface of the fish like some sort of an amoeba.

I have a picture I can post later.

What the heck is this?

Spiney Water Fleas.

I don't think it is the Spiney Water Flea - at least they have not yet been determined to be this far south. By all accounts they are primarily located to the north, near Duluth, in the St Louis River system.

I think what you have seen is some type of algea. The warm water allows that stuff to grow pretty aggressively at this time of year.

Here is a link to some info on the Spiney Water Flea:

Well it was definately alive and moving. I'm sure the pictures will help with an ID. I looked up the water flea and there is a chance it could be that.

Ok, looking at that link, there were no "spines" on this thing. It was round with little flaps like wings.

I have been noticing a lot of slime wrapped around my line this year, kinda a jelly substance and doesn't come off very easily. I haven't noticed anything on the fish, but I haven't inspected them much either. I will pay closer attention now that you bring it up. I cant wait for the picture, as I am curious now.

Well the jelly stuff on your line sounds like SWF's. We got them in the LOTW and that stuff balls up on your line in a jellyish looking mass with fur.

dtro, suppose them bugs are maybe a fish louse of one kind or a nudder?

Anything is possible I guess.

I've had the ball of jelly on my line several times but only after catching a smaller fish and having it roll up my line. I've just assumed that was just slime. Never had the spines or cottony deal (other than the darn cottonwood seeds mad )

Considering how the fish sit on the bottom without moving for long periods of time, it could be the larvae of many creatures. I am think maybe a mollusk larvae.

Google the images of mollusk and clam larvae, maybe adding Minnesota to the search and see what comes up. You can also try Glochidia. Me at worky.

I have noticed it for the last few years and thought nothing of it. I was thinking some sort of frog egg, but ya they are flat and I noticed that they are on more of my fish the closer I get to jordan chaska area. There aren't as many the closer you get to the st.paul

Creepy little critters! I will have to keep an eye out and see if I can find any of those. Maybe they infect the meet on the large cats, and make the meat un-edible shocked

If you are fishing with Darren and he complains of a tummy ache, I suggest you jump overboard and swim for shore.

Those things remind me of some alien critters I saw on an episode from the original Star Trek series!! I do see them somewhat regular on fishes from the LOTW, Walleye and Pikes, seems they like larger sized fish too!

I think until this gets thoroughly investigated, all large cats should be immediately released! grin
