Movements of the overall location and trip principal component means for mullet inmultidimensional space. The reference sites are indicated by the squares with the dottedlines.Most points appear in the top‐left cluster, which contains both times for the Bundaberg reference site. TheFitzroy River, particularly at trip 1, is somewhat removed from the other locations. This was primarily dueto 100% of the sample being ‘diseased’ – all 10 mullet from trip 1 were rated as category 2 for skincondition. Notably, this was a reference site.The main other outlying points are the upper Boyne River at trip 2 (mainly due to the high value forkidney abnormalities – 6 out of the 10 mullet were rated as ‘other’), and the lower Boyne River also at trip2 (which had high values for the hepatosomatic index, HAI score and liver form abnormalities).123
5.5 Summarising by regionsThe means for the individual locations have been combined into regional groupings, as listed in Tables5 .3a to 5.3c.Table 5.3a.
