Conventional equipment and methods used to hold fish during surveys of small streams are either cumbersome or cause injury and kill fish. We designed a live‐bucket that is spillproof, inexpensive (US$20), easily assembled, keeps fish in good condition, and does not restrict a person's movements. The livebucket was used during electrofishing surveys on 120 stream reaches ranging in water surface slope from 090 to 890 and with water temperatures as high as I8°C. Observed mortality while fish were held was less than 190 for cutthroat trout Oncorhynchus clarki , mountain whitefish Prosopium williamsoni , brook trout Salvelinus fontinalis , and brown trout Salmo trutta longer than 80 mm total length.
