New assessment of the conservation status of New Zealand freshwater fishes
IntroductionHave your say on any changes in status of New Zealand freshwater fishes. Consultation closed on 9 May 2022.
Consultations closed 9 May 2022.
This is a call for advice about any changes in status of New Zealand freshwater fishes, including newly recognised taxa, to inform a revision of the assessment for this group in the New Zealand Threat Classification System (NZTCS).
View the current list giving the status of ca. 78 taxa in Dunn et al. 2018, Conservation status of New Zealand freshwater fishes, 2017 (PDF, 7,374K).
Data can be accessed on the NZTCS website.
An expert panel will meet to review the classification of freshwater fishes using information supplied.
An assessment will be made based on the size of the population and the expected trend (amount of decline or increase) for each taxon (species, subspecies, variety, etc) regardless of whether it is taxonomically determinate (having a formal scientific name) or indeterminate (having an informal ‘tag name’).
Guidance on the criteria used to assess the status of species is available in the NZ Threat Classification Manual 2008 (PDF, 478K).

The New Zealand Threat Classification System allows the classification of conservation status/risk of extinction of all organisms known to occur in a wild state in New Zealand. Endemics, non-endemic natives, migrants, vagrants, and introduced and naturalised species are all included, as are taxa which have not been formally described.
The NZTCS is not a priority setting system. It is a resource to support priority setting, among other functions.
Panels of experts from New Zealand’s scientific community determine conservation statuses by assessing population size (number of breeding adults or the area of occupied habitat), forecast change in population size (over either the next three generations or 10 years, whichever is longer), whether the current state of the population is a result of human-induced effects. Groups of organisms are assessed approximately every five years.
The assessments of each group of organisms (eg birds, fungi, freshwater fishes, marine invertebrates) are published as scientific monograph series which are considered part of the formal international scientific literature.
PDF copies of the assessment reports are publicly available on the DOC website.
The assessment data are also publicly available on the NZTCS database.
