? worms in Perch

A group of friends and I are headed to Leech Lake in early Oct. to chase some walleye’s and Perch ( If the large population of walleyes I keep hearing about have not ate all the perch like they have on Mille Lacs ) The last few years we have been getting a rather large amount of Perch with Worms ( small white or yellow ) My question is this. Once a Perch has worms does it always have worms or is there a way for them to go away? One of my friends ask me this and I said I did not know. I thought someone here most likely would. They tend to be worse in the fish that we catch out of the shallow water than those caught out of the deeper water. The problem is it is way easier to catch the fish in the shallow water than the deeper water. We have been Just cutting out the worms if there is only a few but last year some of the fish we just loaded with them.

Is it worms or is it this:

When I worked up at Leech in 2003, it was in almost all the perch I cleaned. A little gross, but you could cut around it most of the time.

Shore Lunch makes them tayyySTEEE!

Note the Herons are mostly located in shallow water.

Yellow Grub, Clinostomum complanatum
Adult yellow grubs are flukes and live in a heron’s mouth. The larval stage, called a metacercaria, is the form referred to as a yellow grub. It appears as a yellowish cyst in the flesh or just under the skin of fish, most commonly yellow perch but also black bass and sunfish. Yellow grub doesn?t infect humans.

Life Cycle: 1 The eggs move from an infected heron’s mouth into the water while the heron is catching fish. Once in the water, the eggs hatch almost immediately into miracidia.

2 When the miracidia come into contact with a ram’s horn snail, they burrow into it and migrate to the snail’s digestive gland or liver. The miracidia develop into sporocysts, which produce larvae called mother rediae. Each mother redia produces three to 15 daughter rediae.

3 Daughter rediae form cercariae, which escape from the snail into the surrounding water. When the cercariae encounter a fish, they burrow into it and form a cyst, often near the tail or front fins. They develop into metacercariae —yellow grubs—within about 20 weeks.

4 When a heron eats infected fish, the metacercariae migrate to its mouth and matures into flukes. There the flukes produce eggs, beginning the cycle again.

Effects on Fish: Yellow grubs usually have no significant effect on fish.

Effects on People: Like other parasites of birds, this fluke will not infect people. If you want, you can remove the cyst with a knife. When the fish is cooked thoroughly, the cysts will die and not be noticeable.

No it is not that – We have got several fish with that as well. We have always tossed those fillets

I should have know BK would know the answer or where to find it – he knows everything !!!! So to answer the friends ? – Once a fish has the worm it does not go away. Is that correct?

Yes.

And thank you very much.

This topic has been brought up at least 4 times over the years. After the 3rd time I normally remember it.

The grub can live up to four years in a fish.

So I guess it can go away.

Wash perch filletts in poorly lit room and moreblack pepper in the flour problem solved

we cleaned up a whole bunch from Leech and only 3-4 had worms, I know we were in 6-7 FOW also, but late in the year I think those deep fish come in shallow to stock up for winter. I have also see that other stuff which looks like you splashed some bleach on the fillets, throw those out!
