Infested Lake Trout

[Big T]

Has anyone see a parasite infestation in the guts of a lake trout like this. This came out of a 10lb lake trout from cold lake.

Are those worms?

Maybe you should google it. I am interested to know what that is.

Abstract

A comparative summary of the literature on parasites reported from lake trout, Salvelinus namaycush, from the Great Lakes is presented. Twenty-four studies on parasites infecting lake trout in these lakes have been published since 1874 with 32 parasite species (1 Monogenea, 3 Digenea, 9 Cestoidea, 6 Nematoda, 6 Acanthocephala, 1 Annelida, 5 Crustacea, 1 Fungi) being reported. The most common parasites are Eubothrium salvelini and Echinorhynchus salmonis in the intestine, and Cystidicola stigmatura in the swim bladder. Most of the parasites occur in the gastrointestinal tract. Twenty (80%) of the 25 helminth species reported from lake trout are represented by adults. The dominance of these helminth species is attributable to the position of lake trout in the food web of the Great Lakes as top predators. Parasitological data from splake, Salvelinus namaycush X Salvelinus fontinalis, from Lake Huron are also presented.

I did a fairly extensive search on the internet and the only thing I could come up with is a "thorny headed worm" but no real pictures to match. Those larger worm looking things are anywhere from 2-4 cm in length and about 0.5 cm in width. They were attached all along the length of the intestine/stomach by one end and fed thinner worms/tentacles into the intestine (which you can see cause I cut it open).

I like the Ernest reference!

X2 ya and infestation of that level is rare and they would love to get there hands on it.

maybe I'm missing what you are making reference to in the photo but try looking up "pyloric caece" which is just a normal part the fishes digestive tract.

Those are not worms, do not worry about it,mostly all the larger lakers 10 lbs and up are like this.
What gets my skin crawling are those little skinny white parasites about 1/2 long that found on the outside of the body on some of the larger lakers .
Best I find to get them off is to just lay the dead fish down on the ice and they will start leaving to host.

I couldnt see any worms in that pic either, but lets say there are and it will keep people from fishing out the lakers.

Those big juicy worm looking structure are a normal part of the fish! Have you not filleted any fish before and noticed this structure? There are no parasites that look like what you think are parasites in this fish. Like others have said this is the pyloric caeca. I hope you didn't throw the fish away, because that would just be a very uneducated move. Now if you look where the intestine is cut open there are some very fine white strands, those look more like worms or parasites that can exist in fish, but pretty harmless. Just cook the fish well they are usually just in the digestive tract.
