Would removing the non-native carp from the Arboretum Waterway improve its clarity? That’s the question the Carp-Dependent Urgent Management, or Carp-DEUM, Project set out to answer this spring before the coronavirus halted many research projects.
In the first part of the survey, conducted in early March, the team used nets to sample fish from the middle sections of the waterway. They found relatively few carp but a lot of fathead minnow, black bullhead, green sunfish, mosquitofish and a single goldfish. They also found numbers of turtles, crawfish and a cash register. (But no bicycles.)
Carp may be more abundant in the lower reaches of the waterway, which are easier to navigate for them, the authors write.
