Experimental setup used in the functional response trials A experimental arena with a signal crayfish and snail prey during a trial B water from the tank containing largemouth bass (left) was pumped to a head tank (upper right) and C distributed to the experimental arenas in the predator treatment (upper-left row) or water was supplied directly from Lake Washington to the control arenas (lower-right row). Blue tanks in the background were stock and starvation tanks where crayfish were kept before being used in trials D the water from both treatments was supplied to each experimental arena via individually controlled hoses.
