Biology     Glossary (e.g. epibenthic)

Adults occur in freshwater to estuarine conditions. Adults breed at sea, throughout the year; juveniles move into estuaries and enter rivers usually in late winter or early spring (Ref. 52193). Females remain in freshwater for 7 years, males for 4 years (Ref. 52193). Return to estuaries before maturing sexually prior to spawning (Ref. 52193). Oviparous, eggs are pelagic and non-adhesive (Ref. 205). Feed on benthic algae and small invertebrates over muddy bottom (Ref. 6465). Decline in population from obstruction, by dams and weirs, of free passage into rivers.

Life cycle and mating behavior Maturities | Reproduction | Spawnings | Egg(s) | Fecundities | Larvae

Breed at the sea throughout the year. Juveniles move into estuaries and enter rivers usually in late winter or early spring. Males remain in freshwater until 4 years, females for up to 7 years. Fish return first to estuaries before maturing sexually prior to spawning (Ref. 7248).
