TOWNSVILLE BARRAMUNDI 2018

Barramundi are a popular local sports species.

  • Overview

    Overview - Crystal Bowl Rated Premium Fishery

    Crystal Bowl GBR is aiming to examine 3 core measures across a wide range of species in the region:

    • Fishing experience (how many fish per trip)
    • Quality of the fish (size of fish)
    • Community attitudes (number of legal size fish kept or released)

     

    Fishing Experience

    • T20 Fishers (Sportfishers) catch rate 1 fish/fisher/day in 2017 
    • Qld Fisheries Boat Ramp Surveys reports catch rate of 0.3 fish/fisher/day in 2017
    • Townsville ranked 6th in the state for Barramundi catches based on Qld Fisheries Boat Ramp Surveys
    • An increase in Barramundi Commercial Catch Rates, from 52.2kg/day in 2016 to 76.8kg/day in 2017, was reported

     

    Quality of the Fish

    • The most commonly reported size of barramundi in 2017 by T20 Fishers (Sportfishers) were fish >801mm 
    • Townsville ranked 12th in the state for average length of Barramundi (based on Qld Fisheries Boat Ramp Surveys) however, due to the small sample this ranking may be biased

     

    Community Attitudes

    • 2017 Qld Fisheries Boat Ramp Surveys reported 80% of Barramundi caught in 2017, were released
    • 76% of Barramundi reported in 2017 were caught by locals 
    • Townsville is ranked 5th in the state for the release rate of fish

    Full 2018 Barramundi Forecast

    T20 Fishers

    • There will be a reduction in the percentage of legal fish in the catch due to the size range of fish spilling from Awoonga in 2017 being predominantly 500-700mm
    • Overall catch rate and catch rate for legal fish will remain steady but may increase if fish spill from Lake Awoonga again as is possible in early 2018 (Feb-Apr)
    • Catch rates in the Boyne River likely to be higher than for remainder of Gladstone Harbour due to fish spilling from Lake Awoonga in 2017 with little evidence of these fish moving beyond the Boyne River
    • Stock level to remain steady with natural and fishing mortality likely to be offset by additional fish spilling from Awoonga

    Commercial Fishers

    • Commercial Barramundi catch data for 2017 is only available for Feb-Sep and that indicates catch and catch rates are within the forecast range
    • Commercial catch and effort data will be updated when complete 2017 data are available

    Environmental conditions

    • Neutral to slightly La Niña conditions are forecast for the recruitment period (Jan-Apr) with an average wet season with neutral conditions for the remainder of the year
    • Forecast for Gladstone catchments is a 50-60% chance of exceeding median rainfall from Feb-Apr and rainfall to date suggests that conditions may not be conducive to good recruitment (expected)

    Heavy harvesting of Barramundi is not recommended. Natural recruitment of Barramundi in Gladstone is poor to moderate even in good conditions. Top up stocks from Awoonga maintain stock levels but this population is vulnerable to localizedstock reduction if Awoonga dam levels drop.
