Four simulated mixtures are presented; each mixture comprised eight samples (each making up 12.5% of a 100% individual mixture) with mixtures 1 and 2 including a river from each reporting region, mixture 3 a combination of southern rivers (incorporating two rivers from each region) and mixture 4 a combination of northern rivers (incorporating two rivers from each region). Stock compositions were estimated at the level of individual sample sites (3rd column, 'Sample Estimate') and reporting regions (4^th column, 'Regional Estimate') via the allocate and sum method. One-hundred fish were used in the mixture sample, with 100 simulations. Individual samples are identified by tributary name; see Additional File 1 for details of latitude and longitude, collection date and individual sample size.
