Why Does This Trout Have a Lesion

Type: Freshwater
Region: Central
Location: Great Seneca Creek

I'm seeing a large percentage of the stocked trout I've caught this year have some sort of lesion on them. What is it, why do they have it and are they still safe to eat? This 11" rainbow was caught in Great Seneca Creek this week. I have only seen this on stocked trout the last couple of years and never this common. Of the 7 or 8 fish I caught, probably half of them had a similar scar.

DNR Response: We seem to have more of these fish this year than in previous ones. The lesions are not uncommon in hatchery reared fish, they can occur from a variety of reasons ranging from broom nicks, being stepped on, overcrowding, and birds. When the fish receive an abrasion the area can sometimes become infected. The fish are raised in an unnatural environment and sometimes crowded conditions.

The fish were tested a few years ago when some of the fish had these lesions and they were deemed safe for consumption. If for some reason the infected area gets into the meat DNR recommends cutting around the infected area.
