Freshwater ecosystems constitute only a small fraction of the planet's water resources, yet
support much of its diversity, with freshwater fish accounting for more species than birds …

Traps (or pots) are one of the oldest and most widespread scientific survey gears for fish and
decapod crustaceans around the world. Here, I review and synthesize the extensive …

Environmental flows are a key restoration technique for conserving ecological function in
flow‐degraded rivers. Species‐specific, flow–biota relationships are increasingly being used …

Dams and weirs impede the continuity of rivers and transit of migratory fish. To overcome
this obstacle, fishways are installed worldwide; however, management after installation is …

Most demersal fishes are difficult to observe and track due to methodological and analytical
constraints. We used an acoustic positioning system to elucidate the horizontal and vertical …

Relationships between river flow characteristics and fish community/population dynamics (ie
flow–ecology relationships) underpin methods to determine and monitor environmental …

We present a novel system of drifting pelagic baited stereo‐video cameras that operate in
deep‐water, topographically complex environments typically considered inaccessible for …

Conservation action is usually triggered by detecting trends in species' population size,
geographical range, or occupancy (proportion of sites occupied). Robust estimates of these …

Environmental DNA (eDNA) sampling has emerged as a powerful tool to detect and quantify
species abundance in aquatic environments. However, relatively few studies have …

Unbiased counts of individuals or species are often impossible given the prevalence of
cryptic or mobile species. We used 77 simultaneous multi-gear deployments to make …
