Using an open channel flume, this study quantified upstream passage of European eel
(Anguilla anguilla) and river lamprey (Lampetra fluviatilis) at a model Crump weir …

Globally, populations of diadromous anguilliform morphotype fish, such as eel and lamprey,
have experienced substantial declines, partly as a result of habitat fragmentation caused by …

The behavioural response of downstream moving European eel (Anguilla anguilla) and
brown trout (Salmo trutta) to velocity gradients created by orifice weirs placed in a flume …

Weir construction has fragmented many rivers, resulting in the exclusion of some fish
populations from suitable habitat. A cheap retrofit fishway for small, sloping weirs is the Low …

In aquatic systems, in-stream structures such as dams, weirs and road crossings can act as
barriers to fish movement along waterways. There is a growing array of technological fish …

A new design of a labyrinth weir is introduced in this study by adding a square pool to the
vertex of a one-cycle triangular labyrinth weir with a sidewall angle of 45°. The addition of …

Passage performance of upstream-migrating lamprey (Lampetra fluviatilis) was compared
between sections of a Crump flow-gauging weir with and without studded tiles, and at a …

Installation of baffles intended to improve fish passage through culverts can reduce
discharge capacity and trap debris, increasing flood risk. A sloping upstream face may …

This study deals with hydraulic characteristics for different weir types and effects on
upstream migration of fish in a pool-weir fishway, and presents an optimal design of weir for …

The number of low-head barriers to fish migration far outweighs the number of large
magnitude barriers and thus the cumulative negative impact on fish communities could also …
