| Description of life cycle and mating behavior | There appears to be individual movements into spawning areas with the males arriving first at spawning areas (Ref. 27547). It occurs at night, with spawners forming a great globular mass, each pushing toward the center (Ref. 28694), or at least milling around close together (Ref. 28697), releasing eggs or sperm. Observed to make postspawning runs upriver, apparently for feeding (Ref. 28697). Eggs hatch after 40-70 days. After about 2 months, juveniles are benthic, grow rapidly, reach about 8 cm SL within first year. (Ref. 59043). |
