#MaryRiver #cod thriving in #BrisbaneRiver catchment, century after relative #Brisbane River cod went #extinct & five years after thousands of fingerlings were introduced.
#Ecologist & #IpswichCityCouncil #waterway health officer Jack McCann said the Brisbane River cod went extinct sometime in the 1920s or 1930s.
Their disappearance led to the river losing one of its key apex predators.
