2.3 Spawning grounds
Even though barramundi can live in either fresh or salt water, their eggs and early stage larvae
will only survive in sea water (salinities between 22 and 40 ppt). For this reason breeding takes
place in river mouths and bays near areas of suitable nursery habitat. Areas such as mangrove
swamps and low-lying land that becomes flooded during spring tides and monsoonal rains
provide ideal habitat for juvenile barramundi.
