Abstract A straight-channel stream simulator consisting of a pool-riffle sequence with gravity flow from a nearby stream is described. The facility has a food-producing channel at the upstream end to augment the natural food supply for fish used in experiments, and a riffle with an adjustable slope to simulate a range of stream gradients; both are new features. The simulator has proved to be a valuable tool in gaining insight into the biology and interactive ecology of small fishes.
