A Tasmanian landlocked population of the normally diadromous fish Galaxias maculatus (Jenyns)

A landlocked population of the normally diadromous fish Calaxias maculatus is recorded for the first time from Tasmania. The differences between the landlocked population and normal diadromous C. maculatus are examined and discussed. The association with other species together with the probable mode of origin of the landlocked population are considered.
