Project Description
Stream connectivity during low-flow conditions over an appropriate stream length that allows for successful egg and larvae development appear to be the most pressing flow need (Mills and Mann 1985; Nunn et al. 2003; Durham and Wilde 2006, 2008, 2009; Perkin and Gido 2011); however, it is unclear the role higher flows play in facilitating spawning migrations. This study would assess movement by pelagic broadcast-spawning fishes over multiple spatial scales (mesohabitat, segment) before, during, and following the spawning period.
Conservation Area
CanadianNFCA Objectives
Understanding the movement of these fishes is necessary to prescribe appropriate conservation and management actions. For example, if some flow conditions facilitate upstream movements at certain times of the year, water releases during that period may be enough to prevent isolating populations that can no longer reproduce successfully.
