7 Gladstone region findings from barramundi stocks report

The "Crystal Bowl" is a unique process developed in Central Queensland for the prediction of Barramundi stocks, covering the Fitzroy River and Gladstone areas.

This week the Crystal Bowl gained international recognition at the EIFAAC International Symposium on Recreational Fisheries held in Lillehammer in Norway.

>> Commercial fishermen reeling in 50% less barrramundi

The report compared this year's findings to 2014.

Here are the main findings for the Gladstone region:

  • No changes to size ranges of fish
  • Lake Awoonga spilled from mid-Jan-mid-Mar 2015 spilling more stocked fish, particularly into the Boyne River and the Gladstone area to a lesser extent. 
  • Change in the catch rate for commercial fishers likely to be due to continued spilling of fish from Lake Awoonga.
  • No change in taggers catch rate for legal fish.
  • River flows, catchment rainfall and Cyclone Marcia resulted in conditions favourable for strong natural recruitment.
  • Actual recruitment moderate and expected to be moderate by end of 2015 season.
  • Low numbers of fish deaths in Boyne River had little effect on stock level.
