Abstract

The Queensland Ecological Risk Assessment Guideline (the Guideline) was released in March 2018 as part of the Queensland Sustainable Fisheries Strategy 2017–2027. This Guideline provides an overview of strategy being employed to develop Ecological Risk Assessments (ERAs) for Queensland’s fisheries. The Guideline describes a four-stage framework consisting of a Scoping Study; a Level 1, whole of fishery qualitative assessment; a Level 2, species-specific semi-quantitative or low-data quantitative assessment and; a Level 3 quantitative assessment (if applicable).
The aim of the Level 1 ERA is to produce a broad risk profile for each fishery using a qualitative ERA method described by Astles et al. (2006). The method considers a range of factors including the current fishing environment (e.g. current catch, effort and licensing trends), limitations of the current management arrangements (e.g. transfer of effort to already saturated markets, substantial increases in fishing mortality for key species, changing target species) and life-history constraints of the species being assessed. In the Gulf of Carpentaria Line Fishery the Level 1 ERA assessed fishing related risks to 15 ecological components including target & byproduct species, bycatch, marine turtles, sea snakes, crocodiles, dugongs, cetaceans, protected teleosts, batoids, sharks, syngnathids, seabirds, terrestrial mammals, marine habitats and ecosystem processes.
Based on the outputs of the Level 1 ERA, the GOCLF will not be progressed to Level 2 ERA. The Level 1 ERA identified drivers of risk for target & byproduct species, but these will best be addressed through a Harvest Strategy when one is developed for the fishery. Knowledge gaps for this ecological component were also identified in the Level 1 ERA, and these will be put forward to the Fisheries Queensland Monitoring and Research Plan.
