GLADSTONE SADDLETAIL SNAPPER 2018

Saddletail Snapper are a popular food species and are the most commonly targeted offshore species. Most of the offshore activity for reef species around Gladstone is conducted by recreational fishers.

  • Overview

    Overview

    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

     

    Fishing Experience

    • Qld Fisheries Boat Ramp Surveys reports catch rate of 1.74 fish/fisher/day
    • Saddletail Snapper were not commonly reported (14th most common at boat ramp surveys
    • Increase in Commercial Catch Rates, increasing from 6.84 kg/day (2015) to 10.3kg/day (2017 Incomplete)

     

    Quality of the Fish

    • 2017 Qld Fisheries Boat Ramp Surveys 628 mm
    • Gladstone Ranked 2nd in the State for size of Saddletail Snapper but due to small sample size there is high uncertainty in that ranking.

     

    Community Attitudes

    • 67% of fish reported at Qld Fisheries Boat Ramp surveys are released
    • Gladstone has the 5th highest rate of released fish in the state but due to small sample size there is high uncertainty in that ranking.
    • 91% of fishers surveyed were locals

     

  • Assessment

    Limited Take For Consumption Advised

    Saddletail Snapper are a small portion of the offshore catch for all species off Gladstone. Limited data makes full assessment difficult. Without clear evidence of stocks, some caution should be exercised on harvest.

    Heavy harvesting of Saddletail Snapper is not recommended, but a moderate take for consumption is unlikely to adversely affect stocks based on available data. 

  • Forecast

    Forecast

    • Catch rates will be in a similar range in 2018 (+20 - -20%)
    • Average size of fish is likely to be similar in 2018 (Average 480mm)
    • Recruitment is unknown

    Summary

    Capreef monitoring comprised surveys conducted between 2006-2009 on the local attitudes and experiences when it comes to the offshore fishing experience.  The baseline established by Capreef provides context for assessments a decade later.

    In examining the recreational catch over the past 3 years Longfin Rockcod was the most caught species (19%) while Coral Trout was the most likely species to be kept (85%) and Grass Emperor was the most numerous kept species. School Mackerel was the most caught species inshore, Longfin Rockcod around the islands, Hussar at the Wide Grounds and Redthroat Emperor on the offshore reefs.

    Changes in size limits in 2004 have reduced the proportion of fish kept to less than 1% for Longfin Rockcod and 16% for Red Emperor while for Red Snapper and Redthroat Emperor over 55% are usually kept.

  • Sportfishers

    Gladstone Sportfishing Club

    Saddletail Snapper are targeted by sportfishers for much the same reason as other groups - take home for a feed. As sportfishers practice catch and release for their key estuary targets, offshore represents the opportunity to bring back a feed of fish for the family.

    • Gladstone Sportfishing Club catch rate of TBA fish/fisher/day
    • 2017 Gladstone Sportfishing Club average fish size was TBA mm

     

    • NOTE OFFSHORE DATA IS STILL UNDER REVIEW, UPDATES WILL BE AVAILABLE IN APRIL.

  • Fishing Area

    Area Assessed

    Offshore catch monitoring is more difficult than inshore as each of the monitoring agencies define different boundaries around fishing areas. These boundaries can overlap with other regions.   Fishers from Gladstone for example fish offshore from Rockhampton. Commercially Grids included in the assessment: S30,S31,T30,T31,U30,U31,V30,V31,W30,W31,X30,X31 (Gladstone).
