Does anyone know what this is?

Recommended Posts

I fish a lot of smaller lakes in my area. I basicly have a favorite lake for every species and every season. There is one particular lake that I target for perch and it produces well in both the summer and winter. There is something that I've been seeing over the last 2 or 3 years that has me scratching my head and even a little worried. Some of the larger perch that I catch that are 9+ inches have a funny discoloration in the flesh. When you fillet the fish, half of the fillet will look normal while the other half is an opaque white, almost as if it was already cooked. I typically cut off the entire portion that looks like this and throw it away, but that usually leaves a very little fillet left. Does anyone know what this is? Is it going to harm the perch population in the lake? I sent an e-mail a while ago to the DNR telling them what lake it was in and asked for information on it but the reply I got didn't give me much for info. They basicly told me that they were aware that this was happening but they hadn't quite figured out what it is yet. They also said that it seemed to be perfectly safe to eat. That was about it as far as what information I got out of them. I thought I'd throw this out on the forum and see if someone out there knew more about it.

You shold let the DNR know right away when you catch one. I remember seeing a poster in Bemidji asking you to report it when you found it on area lakes up there. I thought it said something about a bacteria.

the discoloration in the meat is caused by a fungus. The BSU aquatics department is doing a study right now on Leech Lake about this.

I have not noticed the flesh being sandy or grainy in texture. It looks as though it is cooked or freeze dried, solid white, maybe a little yellowish. I was talking about this to someone I work with yesterday and he told me it sounded like a fungus called Heterosporis. I did a search on the internet and that definitely looks like what it is.

Cold feet,
The Mn. DNR was doing a study on that fish disease. I would suggest that you contact them with the info. you have and the lake where you have found the fish that have it.
As far as I can remember they are saying it poses no known harm to humans as long as the fish are cooked well done.

The vast majority of diseases and infections that effect animals and fish cause no harm to humans. As long as the meat is well cooked, and you don't eat it too often (as is outlined in the 2004 fishing regulations), you shouldn't have much to worry about.

The only real concern that you have with fish consumption, as far as modern science is aware of, is parasitic infections, which can be resolved by thorough cooking, and toxicity, which can be reduced by trimming fatty portions of meat from your fillets.

That's a great link. We caught a few like this in Leech last summer. We didn't know what it was and I threw them away, felt bad about it, but eat parasite spores? Yuck.

You would be suprised what you eat that you don't know about. All grain products have a threshhold of certain contaminants(i.e. rodent wastes, bugs...) that can be in them and still sold to the public.

Yeah...you wouldn't want to know what goes into your basic "hot dogs" (the plain weiner kind). I found out once and have since switched to all-beef kosher dogs...less rat feces, less animal brains, eyeballs and intestines, less animal bi-products in those!

    • A good bottle of bourbon or case of beer might make a difference.....
    • Great feedback.  I guess I will go with the single stage.  Just wish I had a solution for keeping the plow driver from pushing our entire culdesac's snow onto my lawn.
    • I have a Gen1 Helix 5 and love it on the ice, but also use it on my kayak. If I were to do it over again I would have got the 7" or bigger. Its not so much an issue on the ice but DI/SI is hard  to fully utilize on a 5" screen.
    • I always use 6lb mono for jigging rods and And 8lb mono on deadsticks. No leaders for me I’ve debated it but it doesn’t really seem to make a difference if you have one or not. 
    • My thinking is the grease would make up for the gap, but wasn't sure if it'll still have too much play. Yet, don't want it too tight where it gets stuck.
    • I think the tube is DOM 1/2" thick. Was afraid 1/4" too thin and cannot find any other tube that would fit another solid rod inside. Don't want to get something I have to get machined $$$... At least with arm I can pull out and have another made if not good. Not sure how to make the grooves with hand tools?
    • I live in the burbs  on a cul-de-sac and the plow always leaves a huge pile at the end of my driveway. I bought a single stage Toro, and while I don't have a 2-stage to compare it against, I would definitely buy a single stage again. It's plenty powerful enough to handle the deepest, heaviest snow that accumulates on the driveway. When it comes to the pile at the end of the driveway, you just have to work your way though it by backing out and pushing into it again. Of course, if you're out of town or something and the pile at the end of the driveway freezes you might need to get out a shovel. But for most snowfalls I can clean the driveway in a matter of minutes - you almost have to run behind the thing to keep up with it.
    • Not a fan of leaders, far fewer bites with them on.   I typically run 4 or 6 lb test.  I do run 8 lb in water less than 8-10 ft.  I do this because thr fight is usually off to the sides of the hole, and the line contacts the ice edge at sharper angles.    
    • Just ordered the 16 piece jig kit yesterday. I am excited to get them and get out on the ice as soon as it is safe!
    • Hey,   What lb test line should I be using for Walleyes?  I've been using 4 lb but that seems a little light and I don't want to lose the big one, but don't want to get too heavy either.  Also, what's your input on using a leader?  I haven't but just wondering if I am missing something.
