Recreational fishery characteristics 14 MFish has no information on recreational catch of silver dory. Due to the offshore location and depth distribution of this species, recreational catch is likely to be negligible. Customary fishery characteristics 15 MFish has no information on customary catch of silver dory. Due to the offshore location and depth distribution of this species, customary catch is likely to be negligible. Management Existing management information 16 Silver dory is currently managed as an open access, non-QMS fishery. Provisional catch history implications (Schedule 4C and 4D stocks or species) 17 Silver dory is a Schedule 4D stock. If introduced into the QMS before 1 October 2009 quota allocation will be by way of provisional catch history. International obligations 18 There are no international obligations specific to silver dory. Treaty settlement obligations 19 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 silver dory. 76
Risk analysis and evaluation STOCK: Silver Dory (Cyttus novaezealandiae) 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 fishing years 2002/03 – 2006/07 indicates that catch varied between approximately 1,034 tonnes in 2004-05 and 484 tonnes in the most recent fishing year. It is uncertain what led to the large decrease in catch over the last two fishing years. Silver dory is taken as bycatch in at least 30 fisheries that target QMS species and the decline might reflect overall decreased effort in associated target fisheries. The catch of jack mackerel (the principle target fishery in which silver dory is taken) has also decreased over the last two fishing years although whether this is due to reduced effort is unclear. The decline in silver dory take may also be due to natural annual variation in silver dory stocks, changes to the spatial distribution of effort in target fisheries taking silver dory as bycatch, or a fishing-related cause that affects silver dory stock abundance. Nothing is known regarding reproduction, recruitment, or habitat interactions of silver dory. Given the highly variable reported catch, the level of risk to silver dory stocks is difficult to assess although decreases in catch over the last two years provide some cause for concern. Severity of impact (low, medium or high) : Medium Likelihood of impact (low, medium or high) : Low Risk score (1-9) : 3 Generic objective 2: Risk to avoiding, remedying or mitigating any adverse effects of fishing on the aquatic environment. Analysis: The risk of adverse effects on the aquatic environment from catch of silver dory under an open access management regime is low due to the fact that there is no target fishery for the species. Some catches of silver dory are taken by bottom trawl, but only as a consequence of a target fishery for QMS species. Nothing is known of the habitat interactions or of the marine ecosystem role of silver dory but due to its widespread habitat, it has some function in the marine ecosystem. 77
