Application of piscicide is a commonly used method to remove nonnative fishes from streams for restoration of native fishes. In remote or inaccessible areas, transport facilities are limited and equipment must be portable and durable. We used 5‐gal plastic buckets with sealable lids and readily available commercial hardware to construct a constant‐flow device modeled on the Mariotte bottle. The device dispenses a selected steady flow of liquid piscicide over a 1–4‐h period. It is economical, easily transported, and simple to construct.
