The age of a fish is estimated by examining the ear bone or otolith (shown in the photo inset).
The harvest of barramundi, an iconic Queensland species, is monitored by collecting biological information from commercial fishers and recreational anglers.
This biological monitoring program started in 2000 and currently collects barramundi samples from commercially caught fish from two important genetic stocks, the Gulf of Carpentaria and the North East Coast.
This sampling focuses on collecting length, sex and age data of the fish - information which helps to assess the sustainability of the fishery.
On the East Coast and Gulf of Carpentaria a boat ramp survey program records recreational fishing effort, catch and release numbers and lengths of key fish species, including barramundi.
How is the data used?
The biological information collected through the monitoring program is combined with other available information such as commercial catch and effort from compulsory logbooks and recreational catch and effort from periodic phone and diary surveys. This combined information is used to carry out regular assessments of the status of barramundi stocks and evaluate the performance of management arrangements for the fishery.
Commercial fishers assist the program by measuring their fish or keeping the fish frames.
How are they monitored?
The monitoring program for barramundi relies on community involvement, through voluntary participation by recreational and commercial fishers and seafood retailers. Commercial catches are also sampled by Fisheries Queensland staff onboard commercial vessels.
