📖 Overview

Females remain in freshwater for 7 years, males for 4 years . Return to estuaries before maturing sexually prior to spawning . Oviparous, eggs are pelagic and non-adhesive . Feed on benthic algae and small invertebrates over muddy bottom . Decline in population from obstruction, by dams and weirs, of free passage into rivers.
