Movement of juvenile barramundi (Lates calcarifer) through a cone ramp fishway at a modified coastal wetland in central Queensland, Australia

Abstract

Barramundi (Lates calcarifer) often migrate from marine to fresh water as juveniles. In March 2018a relatively large number of small juveniles (<100mm) were recorded moving through a fishway on a tidal interface barrier in central Queensland, Australia. This is in contrast to the few documented observations of transitional movements, which involved mostly larger juveniles (250–400mm).
