Abstract Text: Major fisheries in New Zealand are managed under the Quota Management System (QMS). Individual transferable quotas are set as a proportion of an annual Total Allowable Commercial Catch (TACC). The fishery comprises two species, Anguilla australis and A. dieffenbachii. The South Island eel fishery was introduced into the QMS from 1 October 2000. The North Island fishery is due for introduction from 1 October 2004. Eel catches have remained relatively constant since the early 1970s. The average annual catch from 1989/90 to 2001/2002 (fishing year) is 1,313 tonnes. Catch per unit effort (CPUE) remained constant over the period 1983 to 1989 and reduced over the period 1990 to 1999. Statistically significant declines in CPUE for A. dieffenbachii were found in some areas over the latter period. Freshwater eels have particular significance for customary Maori based on the extensive historical exploitation of eel stocks. Management policies allow for customary take and the granting of commercial access rights on introduction into the QMS. For management an annual stock assessment process is undertaken which provides an update on stock status. Required research for sustainable utilisation is focused on a medium term research plan and annual projects are subject to contestable tender.
