"The brook stickleback is carnivorous. A wide variety of aquatic insects,
especially larvae and crustaceans are the principal food items.

In the Madison area (Dane County), more than 47% of the volume of food eaten
consisted of insects, and 38% consisted of entomostracans (Pearse 1918).
Winn (1960) noted that fish eggs, its own and those of other species, are a
minor item in the brook stickleback's diet.

In Illinois (Forbes 1883), half of the stomach contents of four brook
sticklebacks consisted of filamentous algae and the other half of insects
(nearly all aquatic larvae of Chironomus) and Entomostraca (with Cladocera
the most abundant).

In Minnesota (Nurnberger 1928), brook sticklebacks had eaten algae, sponges,
Entomostraca, and insects and their larvae."
