Info

Management Existing management information 26 Rattail species are currently managed as an open access, non-QMS fishery. Provisional catch history implications 27 Rattails – family Macrouridae are listed on schedule 4D. If introduced into the QMS before 1 October 2009, quota allocation will be by way of provisional catch history. International obligations 28 There are no international obligations specific to rattails. Treaty settlement obligations 29 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 rattails. 56
Risk analysis and evaluation STOCK: Rattails – family Macrouridae 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: Reported catch data for the last five fishing years shows that large catches of rattails are taken annually. Catch is dominated by FMA 3 with large catch also taken in FMAs 4 – 7. There appears to be a decreasing trend in rattail catches with catch reported against the RAT code declining by 42 % over the last 5 years. At least some of the decrease in rattail catch is attributable to decreases in the TACC of hoki and orange roughy stocks over this period. From 2002/03 to 2005/06 about three quarters of the rattail catch was landed with the remainder discarded. The percentage discarded increased to close to 50% in the most recent fishing year. Of the rattail landed the amount landed green has been steadily increasing and now accounts for close to 50%. There is some evidence that the larger rattails may be processed as they reportedly provide good edible fillets. However it is unclear what fraction of the catch of these species is reported against the species code rather than the generic RAT code. There is no evidence that a target fishery is operating for any of the rattail species. Little is known about the biology and life history characteristics of rattails and, given the predominant use of the generic RAT code, it is difficult to determine whether catches of individual species are sustainable. It is known that some rattail species are long-lived, which raises some concern. However, this is balanced against the widespread and locally abundant distribution typical of rattail species. Rattails have been a consistent component in the bycatch of New Zealand’s middle-depth and deepwater trawl fisheries since their inception and remain well represented in catches across a broad range of fisheries.
