Census of annual pup production by Australian fur seal populations, Australia (1986-2015)

In Australia, it is thought that up to 26 Australian Fur Seal (Arctocephalus pusillus doriferus) colonies existed prior to the onset of commercial harvesting in the early 1800s [34]. The uncertainty regarding the number of colonies is caused by an inability to determine the exact location of all sealing locations and a lack of clarity as to which species was harvested [35]. At the end of commercial harvesting in 1921, fewer than 10 Australian Fur Seal colonies were extant with greatly reduced numbers of fur seals [35]. The number and size of colonies in south-eastern Australia have regenerated subsequently , but with 20 breeding sites identified in 2007 the population is still considered to be in recovery
