Western Australian

Genetic analysis indicates that there are two separate biological stocks of Redthroat Emperor in western and eastern Australian waters1. Reporting of stock status is at the biological stock level. Stock status East coast Queensland biological stock The most recent assessment (2006) of the east coast Queensland biological stock2 of Redthroat Emperor analysed fishery data using an age-structured model that incorporated all available information on catch, catch per unit effort and age structure. The model estimated that biomass in 2004 was approximately 70 per cent of the unfished (1946) level. The maximum sustainable yield was estimated to be in the range of 760–964 tonnes (t) per year. Since 2004–05, annual commercial catches have averaged approximately 250 t. The latest recreational estimate (for 2010) was 90 t, with the combined catch being well below the estimated maximum sustainable yield3. The biomass of the stock is therefore not recruitment overfished
