Other fisheries reporting significant quantities of redbait bycatch are squid (17%) and barracouta (14%). There may be a small targeted fishery with 2% of estimated redbait catch reported as targeted in the 2004/05, 5% in 2005/06 and 3% in 2006/07. 14 Analysis of fish discards from 1998-2001 observer data in the jack mackerel and squid trawl fisheries showed that the percentage of redbait catch discarded was 19 and 27% respectively. 3 These figures suggest that discards of this species may be underreported. Recreational fishery characteristics 15 MFish has no information on recreational catch of redbait. Due to the offshore location and depth distribution of this species, recreational catch is likely to be negligible. Customary fishery characteristics 16 MFish has no information on customary catch of redbait. Due to the offshore location and depth distribution of this species, customary catch is unlikely. Existing management information 17 Redbait is currently managed as an open access, non-QMS fishery. Provisional catch history implications 18 Redbait is a Schedule 4D species. If introduced into the QMS before 1 October 2009 quota allocation will be by way of provisional catch history. International obligations 19 There are no international obligations specific to redbait. Treaty settlement obligations 20 MFish is undertaking research to provide information on the traditional and customary factors that may need to be considered in the management decision-making process. Currently there is no information specific to redbait. 3 Anderson, O.F.

Risk analysis and evaluation STOCK: Redbait (Emmelichthys nitidus) Severity/likelihood risk analysis: Generic objective 1: Risk to maintaining the potential of the stock to meet the reasonably foreseeable needs of future generations. Analysis: Redbait is primarily taken as bycatch of established jack mackerel, squid and barracouta mid-water trawl fisheries. Over the last 5 years catch has fluctuated between approximately 2,000 to 4,000 tonnes annually with no clear increasing or decreasing trend. There is no evidence of a sustainability concern from available catch data. This may change however if catches increase through development of a target fishery. There appears to be a market for redbait as the amount dressed or landed green has steadily increased over the last three years and now amounts to close to 50%.
