Juvenile and young fallfish primarily consume chironomids and zooplankton. Once they reach 100mm their diet transitions to small fish (including their own young) and prey of opportunity such as fish eggs and terrestrial insects.
Do fall fish taste good?
Despite the "trash fish" reputation, fallfish can make for delicious table fare when prepared correctly. They taste like a wet paper bag with bones.” At some point, when I was a teenager, I read that about fallfish, those large, abundant, aggressive minnows common in most of the Northeast's larger streams and rivers.
How do you catch a fall fish?
To find them, try idling secondary points, the last steep drops in creek arms, and bluff walls off the main lake. Once you mark some baitfish, start fishing. Fall fish movements are a top-down approach, as once you find those baitfish you should be right on some predators.
