Trout of Southeast Minnesota

Following are images we have collected over the last few years during our electrofishing assessments. Spring assessments are conducted during the last two weeks of March and the first two weeks of April. Fall assessments are conducted during the last two weeks of September and the first two weeks of October. These assessments are how we monitor the trout populations of southeast Minnesota.

Below is a photo of two brook trout. The one at the bottom of the photo is a male and the one at the top of the photo is a female. Note the slight color difference and the larger slightly hooked jaw of the male.

 

Male and female brook trout

Male brook trout develop intense coloration in late fall during their spawning time as seen below.
