Trout With Cancer? *pics*

[archerynut]

hey just a question. I caught a rainbow yesterday in the city. it was on a dry fly wich was fun! but the thing that concerns me is the very large tumour-ish growth located on the underside of the fish right between the gills. it was about the size of a large marble and looked to be open and raw. very red in colour. BUT - it didn't seem to slow the fish down which was very acrobatic and did a fair bit of jumping trying to throw the hook. i got a picture of the fish and took a specific picture of this nasty growth. this can't be normal, if this kind of thing was found on a human, they would be starting chemotherapy next week! i'll take the pics off my camera and post both in this thread. if theres any fisheries biologists on the forum, I would really like to see what they have to say.

ok heres two pictures of said rainbow trout. he measured out at 15" and rose for a royal wulf/humpy hybrid.

 

 

so you can see on the underside, right near the mouth is a lump. this is the growth in question. in case anyone is wondering, I made pains not to touch it. I thought about keeping the fish to submit to a biologist for an answer.

 

 

heres the close-up. it was gross...and I happen to work in a hospital on a medical unit so I see ALOT of "stuff" in my line of work. but this...was...gross...

I caught a nice brown in the city yesterday with almost an identical growth. I figured it was an infected hook wound or something. I dont think poaching a fish is a good idea just to identify a growth/ wound.

for the record, in the event that I chose to keep this fish, it would have been legal.

[ÜberFly]

Huh? I don't quite understand where you're going with this?!

 

Did you keep it?!

 

If you didn't, please keep the fish in the water when handling it!

 

P

 

P.S. Probably an wound from a big treble hook.

Ive seen this before south of the city as well...Nasty looking stuff but i`ve caught the same Brown twice with that type of growth a few years ago and he seemed fine both times.

[darrinhurst]

I have caught two or three fish this year with the same things on it. One of them was under the jaw, like yours, but the other had it right on the side of his face. Gross is a gross understatement. Pun intended.

Deff seems to be more common this year on the bow, i have caught 5 fish this year with similar growths. Also caught a brown that kinda had a second mouth forming bellow his other, really nasty. Sorry dont have the answer to your question tho.

 

[Giovanne]

I have seen a lot of trout with this.

 

I don't think just blaming treble hooks is a fair assessment.

Most likely from hook wounds

[archerynut]

if this were the only occurence like this that I have seen, I may be inclined to call it a festering wound from a hook as well. this particular fish came from a small piece of water. also, I have caught other trout both rainbow and brown trout, and seen growths similar to the one pictured but in different spots that normally a hook - treble or single - would not be found. its a mystery, but this fish was caught right near a city street run-off thingy, and when its raining and I happen to be fishing this location, the water coming from opening looks like used motor oil, I wonder if this is partly to blame?

Two of the fish I caught yesterday on dries had old hooks in them. One nice brown had a clouser stuck in his left pectoral fin. There was a large lump around the hook and a bunch of melanin (black pigment) had been released around the area and stained a big, black stripe down his golden fin. Another rainbow had a stonefly nymph stuck in it's back end. Localized inflammation is an immunological response to a foreign body/injury to the flesh.

Darn fly fishermen are trying to poach via snagging.

probably not a bad idea to submit it to the fish and wildlife guys. It may be a parasite they are not aware of, could just be foul hook, could be a growth due to a newly introduced chemical

[reevesr1]

It's more fun to say "treble hook". And absolves us from any possible responsibility.

 

No telling what this is from. Not like a treble hook has any more growth causing properties than any other hook.

I think we should have a weekend to end all Trout Cancer. We can sell wristbands and car ribbons to raise money. Also rickr can shave his head to raise more funds.

Fixed.
