  • Critical Habitat for Canterbury Freshwater Fish, Kōura/Kēkēwai and Kākahi
    CRITICAL HABITAT FOR CANTERBURY FRESHWATER FISH, KŌURA/KĒKĒWAI AND KĀKAHI REPORT PREPARED FOR CANTERBURY REGIONAL COUNCIL BY RICHARD ALLIBONE WATERWAYS CONSULTING REPORT NUMBER: 55-2018 AND DUNCAN GRAY CANTERBURY REGIONAL COUNCIL DATE: DECEMBER 2018 EXECUTIVE SUMMARY Aquatic habitat in Canterbury supports a range of native freshwater fish and the mega macroinvertebrates kōura/kēkēwai (crayfish) and kākahi (mussel). Loss of habitat, barriers to fish passage, water quality and water quantity issues present management challenges when we seek to protect this freshwater fauna while providing for human use. Water plans in Canterbury are intended to set rules for the use of water, the quality of water in aquatic systems and activities that occur within and adjacent to aquatic areas. To inform the planning and resource consent processes, information on the distribution of species and their critical habitat requirements can be used to provide for their protection. This report assesses the conservation status and distributions of indigenous freshwater fish, kēkēwai and kākahi in the Canterbury region. The report identifies the geographic distribution of these species and provides information on the critical habitat requirements of these species and/or populations.

Box 56, Dunedin 9054, New Zealand; [email protected] * Correspondence: [email protected]; Tel.: +47-481-37-867 Abstract: Free-living species often receive greater conservation attention than the parasites they support, with parasite conservation often being hindered by a lack of parasite biodiversity knowl- edge. This study aimed to determine the current state of knowledge regarding parasites of the Southern Hemisphere freshwater fish family Galaxiidae, in order to identify knowledge gaps to focus future research attention. Specifically, we assessed how galaxiid–parasite knowledge differs among geographic regions in relation to research effort (i.e., number of studies or fish individuals examined, extent of tissue examination, taxonomic resolution), in addition to ecological traits known to influ- ence parasite richness. To date, ~50% of galaxiid species have been examined for parasites, though the majority of studies have focused on single parasite taxa rather than assessing the full diversity of macro- and microparasites. The highest number of parasites were observed from Argentinean galaxiids, and studies in all geographic regions were biased towards the highly abundant and most widely distributed galaxiid species, Galaxias maculatus.

The present geological period has more species than any other, yet the current rate of extinction of species is greater now than at any time in the past. Ecosystems and communities are being degraded and destroyed, and species are being driven to extinction. The species that persist are losing genetic variation as the number of individuals in populations shrinks, unique populations and subspecies are destroyed, and remaining populations become increasingly isolated from one another. The cause of this loss of biological diversity at all levels is the range of human activity that alters and destroys natural habitats to suit human needs.” (Primack, 2002). CapeNature launched its State of Biodiversity Programme (SoBP) to assess and monitor the state of biodiversity in the Western Cape in 1999. This programme delivered its first report in 2002 and these reports are updated every five years. The current report (2007) reports on the changes to the state of vertebrate biodiversity and land under conservation usage.

When their wetland habitats dry out in summer, they burrow into the soil and remain there, motionless, breathing air, until the first decent flood of autumn refills the wetland and washes them from their refuge. Few fish species worldwide have such ability to survive for extended periods out of water. Early settlers in New Zealand were surprised to find live fish when digging vegetables from the earth. This ability to survive prolonged periods of drought allows them to colonise habitats that would be unsuitable for conventional fishes, which cannot survive out of water. These cryptic, nocturnal fish were probably once the most abundant freshwater fish in New Zealand. However, the loss of more than 90% of our wetlands over the past two centuries has confined them to a few refuge habitats still threatened by development of adjacent land.

    Correa-Araneda et al. Revista Chilena de Historia Natural 2014, 87:20 http://www.revchilhistnat.com/content/87/1/20 SHORT REPORT Open Access Presence of the red jollytail, Brachygalaxias bullocki (Regan, 1908) (Galaxiformes: Galaxiidae), in freshwater forested wetlands from Chile Francisco Correa-Araneda1,2,3*, Patricio De Los Ríos2,3 and Evelyn Habit4 Abstract Background: Brachygalaxias bullocki (Regan, 1908) is a small-sized freshwater fish species (41 to 46 mm) and endemic to Chile. Its biology has still various knowledge gaps, and its distribution range has been reduced in the last decade due to human intervention. Findings: In this article, for the first time, its presence in forested wetlands of Chile (38°52′ to 39°02′ S) is documented. The presence of this species in these ecosystems is restricted to wetlands with permanent water regime and depths ranging from 15.7 to 83.5 cm. Conclusions: The physicochemical habitat conditions show important seasonal variations, suggesting that B. bullocki is resistant to a wide range of temperatures, as well as different levels of dissolved oxygen and conductivity. Keywords: Brachygalaxias bullocki; Fish fauna; Forested wetlands; Conservation Findings Consequently, B. bullocki changes in the past 26 years from Brachygalaxias bullocki (Regan, 1908) is an endemic, small- a vulnerable status of conservation (Glade 1988; Campos sized (41 to 46 mm) fish species (Stokell 1954; Cifuentes et al. 1998) to almost endanger (MMA 2014).

    Biodiversity Summary for NRM Regions Species List What is the summary for and where does it come from? This list has been produced by the Department of Sustainability, Environment, Water, Population and Communities (SEWPC) for the Natural Resource Management Spatial Information System. The list was produced using the AustralianAustralian Natural Natural Heritage Heritage Assessment Assessment Tool Tool (ANHAT), which analyses data from a range of plant and animal surveys and collections from across Australia to automatically generate a report for each NRM region. Data sources (Appendix 2) include national and state herbaria, museums, state governments, CSIRO, Birds Australia and a range of surveys conducted by or for DEWHA. For each family of plant and animal covered by ANHAT (Appendix 1), this document gives the number of species in the country and how many of them are found in the region. It also identifies species listed as Vulnerable, Critically Endangered, Endangered or Conservation Dependent under the EPBC Act. A biodiversity summary for this region is also available. For more information please see: www.environment.gov.au/heritage/anhat/index.html Limitations • ANHAT currently contains information on the distribution of over 30,000 Australian taxa. This includes all mammals, birds, reptiles, frogs and fish, 137 families of vascular plants (over 15,000 species) and a range of invertebrate groups. Groups notnot yet yet covered covered in inANHAT ANHAT are notnot included included in in the the list. list. • The data used come from authoritative sources, but they are not perfect. All species names have been confirmed as valid species names, but it is not possible to confirm all species locations.
