|Indicator(s)||Catch, Effort, CPUE and mean weight.|
Catch rates (CPUE) and size structure is used as performance indicators in the Tasmanian periwinkle fishery. Increases in size limits in 2009 and 2014 had little (<18%) impact on catch rates. Consistent catch rates and robust size limits indicate this stock is unlikely to be depleted, that recruitment is unlikely to be impaired and that the current level of fishing mortality is unlikely to cause the stock to become recruitment impaired.
