Ever wonder how we survey different fish species in different habitats? Cloverleaf traps are set overnight in shallow nearshore or deeper vegetated (submergent, emergent) backwater habitats. They target small fishes including juvenile sunfishes such as bluegill, central mudminnow, minnows and darters. Cloverleaf traps are three lobed with wide openings between lobes to allow fish to enter.
