Other than a survey of 2022 households by the Animal Medicines Australia group in 2013 & 2016, that focused on social science questions including household makeup, cost associated, and length of ownership, no data has been recorded on a large scale of what spp of fish are owned in Australia. This gap in knowledge is surprising as this is a pressing topic in a country where invasions of environment- and community- altering pest fish is a major issue, and should be addressed by the ABS.
