  • Biology


    Pelagic species preferring close proximity to substrate and seeking out slacker areas such as backwater, eddies and pools below riffles (Ref. 116496). It occurs in shoals and prefers well-aerated, open water in flowing rivers, favouring the upper stratum (Ref. 7248, 52193, 116496). Feeds from water column on planktonic crustaceans and insects, such as midges and ants (Ref. 7248, 52193, 116496). Breeding occurs in early summer; appears to migrate up streams in spring to breed where it is found in tributaries (Ref. 7248, 116496).
