Habitat use and distribution of lithophilic spawning and riffle fishes


July 2016 - June 2019


Often streams below dams have limited gravel due to the dam trapping sediment. However, many fishes need gravel to spawn. Our collaboration with MDC will determine the gravel sizes suitable fish native fish spawning and develop protocols of the sizes of gravel to reintroduce to streams to guide fish conservation.
