Question
Feeding fish In the midwestern United States, a large
aquaculture industry raises largemouth bass. Researchers
wanted to know whether the fish would grow better if fed
a natural diet of fathead minnows or an artificial diet of
food pellets. They stocked six ponds with bass fingerlings
weighing about 8 grams. For one year, the fish in three
of the ponds were fed minnows, and the others were fed
the commercially prepared pellets. The fish were then
harvested, weighed, and measured. The bass fed a natural
food source had a higher average length (19.6 cm) and
weight (95.9 g) than those fed the commercial fish food
