Brook trout at the salmon farm
Found stranded on a dock, likely dropped by a seagull. The animal was released shortly after this photo was taken
Smallmouth Bass are common fish in Maine, tho they're not native, but they were brought in to southern Maine. Unfortunately they made their way to northern Maine, where they wernt meant to be and any Smallmouth Bass above in nothern Maine and northern parts of rivers they are known as invasive.
Found this deceased Atlantic Mackerel on the shore while fishing for Striped Bass in Saco, Maine. My best guess is that it got beached when being chased by predators.
