The recreational Roe's abalone fishery is concentrated on easily accessible reefs that adjoin metropolitan Perth in Western Australia. There is a restricted recreational fishing season of 1.5 h a morning, for six consecutive Sundays in November and December each year. The reefs near Perth are also the focus of the commercial Roe's abalone fishery in Western Australia. The recreational catch and effort for each 10 nautical mile section of the Perth fishery is estimated from a creel survey with instantaneous counts, aerial surveys and interviews with fishers, from 1997–2003. Most of the recreational and commercial catches were taken from small areas of the fishery, with approximately 87% of the recreational catch coming from two 10 nm sections, and 98% of the commercial catch coming from these two and one additional 10-nm section. An annual quota of 36 t limits the commercial catch, whereas estimates of the recreational catch increased from 33–51 t between 1997 and 2003. Recreational catch and effort estimates from 1999 on were corroborated by an independent telephone survey, with independent estimates falling within the 95% confidence intervals.
