Depending on the assumed size at recruitment to the fishery and the assumed rate of M, current estimates of MCY (241–1660 t) and CAY (720–2218 t) are higher than the TACC (200 t). Reported landings have averaged about 187 t annually in New Zealand since 1986–87, which is less than all of the yield estimates. Recent catches have been at about the level of the current TACC. There appears to have been an increase in CPUE in recent years that could be associated with the apparent increase in biomass. Overall, the 2005 biomass and simple yield estimates suggest that fishing at the level of recent average landings is likely to be sustainable in the short term. However, these yield estimates are based on estimates of biological parameters for pipi elsewhere in northeastern New Zealand, and potential differences in the biology of Mair Bank pipi could significantly affect yield estimates. It is, therefore, unknown whether fishing at the level of the current TACC is likely to be sustainable in the long term.
