Stock assessment priorities for Fisheries Queensland

Through its commercial fishery logbooks, recreational fishing surveys, fisheries long term monitoring program and various research projects, Fisheries Queensland collects information to be used in mathematical models of the populations of key fisheries species. From these models, scientists are able to determine whether fishing pressure is likely to be within sustainable limits and advise fishery managers whether changes to management arrangements may be needed. Management changes are made to ensure resources are not overfished and optimum economic returns are achieved.

Because of limited resources available to Fisheries Queensland, only a few species that are major targets for commercial fishers or recreational anglers can be monitored closely and data suitable for further assessment collected. Logbook catch and effort data is collected for all retained species.

Priorities are determined by a number of factors including:

  • assessing impact of recent management changes
  • concerns raised about the status of stocks
  • life history characteristics making the stocks more vulnerable to fishing pressure.

Priorities are reviewed annually. Quantitative stock assessments are generally undertaken by modellers in the Sustainable Fisheries unit in Agri-Science Queensland often working in collaboration with mathematicians at the University of Queensland's Centre for Applied Resource Mathematics and with scientists of other fisheries agencies.
