Pearl perch (Glaucosoma scapulare) are found commonly in sub-tropical offshore-waters along the east coast of Australia and are a valuable table fish popular with commercial and recreational fishers. The species is long-lived, up to 30 years of age, and reaches sexual maturity at between 25 and 35 cm total length. Pearl perch are predominantly line-caught and fishing is managed separately by New South Wales (NSW) and Queensland. Historical fishing data indicate that pearl perch harvests have been consistently higher from Queensland waters with 73% of the total catch landed in Queensland in 2013. Approximately 52% of the Queensland catch is taken by recreational fishers compared with 42% in NSW. In Queensland, the Department of Agriculture and Fisheries (DAF) recently classified the stock status of pearl perch as “transitional depleting” (DAF Stock Status 2015). The status raised concern in both Queensland and NSW as to whether current management arrangements are adequate to protect the sustainability of pearl perch fishery. This stock assessment incorporates data from both jurisdictions and assesses at the whole of stock level; establishes current stock status reference points including biomass and fishing pressure levels for pearl perch; and provides advice on whether additional management measures are required to reduce fishing pressure and rebuild fish stocks.
