Vertical slot fishways are hydraulic structures which allow the upstream migration of fish through obstructions in rivers.An effective vertical slot fishway must allow fish to enter, pass through, and exit safely with minimum cost to the fish in terms of time and energy.

Can vertical slot fishways (VSF) operate with More recently Vertical slot fishways (VSF) Fish can swim through the slot at any desired depth. More efficient with changing water depth.
