With zero direct fish records, no guide coverage and no fishing reports, Akoo Creek is unproven water. The wider Bull River tributary network carries an inferred sportfish signal, most plausibly
westslope cutthroat trout, the trout most likely to hold in small East Kootenay headwater streams like this one, but that is a hypothesis, not a catch record. Nearby recorded small tributaries such as
norboe creek and
barrier creek do carry confirmed westslope cutthroat, which supports the idea that a similar population could hold in Akoo Creek, but only fieldwork on the creek itself would confirm it.
