Rainbow trout - unidentified injury/disease

[goodfishin]

Hit up a lake that has been good to me the last couple years yesterday and hooked into a few nice stockie rainbows.

The nicest of the bunch was about as good as you're going to get of the regular ol' stocked variety. Nice and chunky, good fight.

Had dreams of throwing him on the grill right up until I got him in the net and saw the big lesion on his side. Not sure what the cause of it was but my guess is an injury that got infected. Could be a disease though.

Anybody have a guess at what the poor guy's ailment was?

I'm guessing small Lamprey eel.

Looks like lamprey. What lake ?

[goodfishin]

I considered the lamprey angle but it seems quite unlikely for a few reasons. First, we're talking about a really small little piece of water. Barely larger than a large pond. I was catching one cookie cutter after another in one little section that you'd think would only be heavily populated after a recent stocking - and somebody I was chatting with told me there had been a stocking within the last week or so. So, I find it hard to believe there would be a lamprey in that little lake and find it easier to believe that the trout had an injury that may have even happened at the hatchery and then got infected pre- or post-stocking.

That's just my guess though.

Sent you a PM, AndyS.

Looks like the Piscine Diphtheria to me

The scientific term is a boo boo.

95% sure that it's a scrape from the concrete hatchery walls. Not at all uncommon.
