Barramundi origins: determining the contribution of stocking to the barramundi catch on Queensland's east coast. (Old ID 26618)

Principal Investigator

Barramundi are stocked in impoundments, freshwater rivers and estuaries along the Queensland east coast and there is strong evidence that a substantial proportion of these fish find their way into estuarine and coastal environments. However, what this contribution actually is to the barramundi commercial fishery is unknown. Established methods for identifying the source of fish-genetics and otolith microchemistry-can be effective, but are costly. This project will evaluate near infra-red spectroscopy (NIRS) on otoliths as a rapid approach to identify if a barramundi is stocked or not.
