Workshop to develop a national strategy for hopper R&D in Australian prawn trawl fisheries
It has been suggested that the use of hoppers in prawn trawl fisheries can minimise the effects on bycatch species. Preliminary results from both the Queensland pilot study and research in SA’s Spencer Gulf Prawn trawl fishery support these suggestions. The uptake of hoppers in Australian prawn trawl fisheries is increasing, however, a coordinated and cooperative research approach to quantitatively determine the effects of hoppers has not been attempted.NORMAC’s Bycatch Action Plan has identified research into the effects of hoppers on bycatch survival as a ‘high priority’. The East Coast Trawl Plan also includes the need to reduce bycatch by 40% by 2005 and flags that hoppers could assist achieve this target. SARDI have proposed that hoppers, used as part of a suite of bycatch mitigation devices, could improve bycatch survival.
