Earlier migrants (September) were larger, older and derived from autumn spawning events. Post‐larvae were smaller and younger at inward migration late in the migration season (November) and were derived from winter spawning events. ![]() ![]() A wide range of post‐larval migration traits were observed over the peak migratory period. The chronological properties of otoliths, together with a spatial and temporal analysis of post‐larval migration traits and adult reproductive traits, were used to reconstruct the life history of a widespread, yet declining amphidromous galaxiid, Galaxias maculatus, and to explore relationships between marine and freshwater life phases. Despite this, the conservation and management of amphidromous species is exceptionally challenging because this life history type, with larval development in a pelagic habitat (usually marine) and adult development in fresh water, is poorly resolved. Amphidromy is the most prevalent type of diadromous migration. ![]()
