  • Acoustic and radio-transmitter retention in common carp (Cyprinus carpio) in New Zealand

    Daniel, Adam Joshua; Hicks, Brendan J.; Ling, Nicholas; David, Bruno O. (CSIRO Publishing, 2009)
    Common carp (Cyprinus carpio) are notoriously difficult to monitor in water temperatures above 20◦C using telemetry owing to transmitter expulsion. To reduce transmitter loss, radio transmitters were anchored to the pelvic ...
  • Biomass estimation of invasive fish

    Hicks, Brendan J.; Brijs, Jeroen; Daniel, Adam Joshua; Morgan, Dai K.J.; Ling, Nicholas (Lake Ecosystem Restoration New Zealand (LERNZ) & Department of Conservation, 2015)
    Invasive fish have a variety of effects on indigenous fish communities and freshwater ecosystems generally, and the magnitude of these effects is partly dependent on invasive fish biomass. For example, a koi carp biomass ...
  • Boat electrofishing survey of the lower Waikanae River, Ratanui Lagoon, and Lake Waitawa

    Hicks, Brendan J.; Daniel, Adam Joshua; Bell, Dudley G. (2006)
    We conducted the first electrofishing boat survey of the lower Waikanae River, Ratanui Lagoon, and Lake Waitawa on 11-12 July 2006. We caught five introduced and five native fish species in 4.74 km of fished length from a ...
  • Costs and effectiveness of different methods for capturing invasive fish

    Hicks, Brendan J.; Daniel, Adam Joshua; Ling, Nicholas; Morgan, Dai K.J.; Gauthier, Stephane (Lake Ecosystem Restoration New Zealand (LERNZ) & Department of Conservation, 2015)
    Comparisons of the effectiveness of different fishing techniques in non-wadeable habitats give insights into the relative abundance of invasive fish and native fish, which is important to provide evidence for changes in ...
  • Detecting exploitable stages in the life history of koi carp (Cyprinus carpio) in New Zealand

    Daniel, Adam Joshua (The University of Waikato, 2009)
    Koi carp are a highly coloured strain of common carp (Cyprinus carpio L.) and are an invasive alien species to New Zealand. The introduction of koi carp to the lower Waikato River during the 1980s has coincided with a ...
