  1. NZ Freshwater Fish Database. Don Robertson NIWA Wellington

  2. NZ Freshwater Fish Database includes: • site location • species present • abundance and size • sampling method used • a physical description of the site • The latter includes an assessment of habitat type, substrate type, available fish cover, catchment vegetation, riparian vegetation, water widths and depths, and water quality measurements.

  3. NIWA Freshwater Biodiversity & Biosecurity Data • Four broad categories of freshwater biodiversity & biosecurity data are held by NIWA: • fish • invertebrates • submerged macrophytes • algae

  4. Issues with the freshwater fish database. • User demand increasing (e.g. web map visualisation tools) • $ costs increasing • $ Revenue decreasing • Funding provides for only limited data QA & entry • Not integrated with other freshwater biodata • No metadata system • These issues constrain the emerging demand for a more comprehensive data management system which meets multi-project, multi-institutional requirements to help better meet clients goals (e.g. goals of the NZBS).

  5. A Possible Solution • Gain funding to provide for: • improved data management, • improved application of standards, • improved interoperability across & within institutions, • improved integration of dispersed datasets, • enhanced access, • provision of a national data repository, • facilitation & enhanced use of correlative bio-spatial analyses, modelling and prediction tools, • facilitation of development and application of new data associations & map-based management decision tools, to help achieve the goals of the NZBS.

  6. A Result • TFBIS funding is approved for a project to upgrade NZ’s freshwater biodiversity & biosecurity data management (including the freshwater fish database) with a project to: • Design and implement an integrated multi-user web-interfaced database built using established data management standards, emerging software development standards and protocols; to be a potential repository for all NZ’s freshwater biodiversity and biosecurity data, supported by metadata, species identification guides and map-based tools. • This project could become the national freshwater biodiversity & biosecurity database of choice and, where appropriate, provide links to any associated specimen collections.
