Assessing movement of rainbow trout and common smelt between Lake Rotoiti and Lake Rotorua using otolith chemical signatures: A summary of work so far
(Centre for Biodiversity and Ecology Research, The University of Waikato, 2009-07)This study used otolith microchemistry to investigate movement of common smelt and rainbow trout between Lake Rotorua and Lake Rotoiti. Rainbow trout were collected from Lake Rotoiti, Lake Rotorua and the Ohau Channel, and ... -
Chronosequences of strontium in the otoliths of two New Zealand migratory freshwater fish, inanga (Galaxias maculatus) and koaro (G. brevipinnis)
(World Scientific Publishing Co. Pte. Ltd., 2005)Half of the freshwater fish fauna in New Zealand is diadromous (i.e., migrates between the sea and freshwater); unimpeded access to and from the sea is important for the conservation of diadromous fish. The genus Galaxias ... -
The feasibility of using otolith microchemistry to trace movements of rainbow trout and common smelt in lakes Rotoiti and Rotorua
(Centre for Biodiversity and Ecology Research, The University of Waikato, 2007-05)Otolith microchemistry can be used to determine the natal origins of fish. Our feasibility study using single water samples has determined that the water chemistry around Lakes Rotorua and Rotoiti, have different elemental ... -
Influence of open and closed river systems on the migrations of two northern New Zealand populations of banded kokopu (Galaxias fasciatus)
(New Zealand Natural Sciences, 2012)Otolith microchemical analysis by laser ablation inductively coupled mass spectrometry (ICP-MS) was used to investigate the migratory life histories of banded kokopu (Galaxias fasciatus) in two streams on the North Island ... -
Otolith chemistry, stomach contents and stable isotope analysis of a snapper (Pagrus auratus) caught in the Waikato River at Ngaruawahia
(Centre for Biodiversity and Ecology Research, The University of Waikato, 2009-10)Analyses of stomach contents, stable isotopes and otolith microchemistry were carried out in order to ascertain the length of freshwater residence of a snapper (Pagrus auratus) caught in the Waikato River at Ngaruawahia ... -
Population Dynamics and Migrational History of Torrentfish (Cheimarrichthys fosteri, Haast 1874), in two Waikato Streams on the North Island of New Zealand.
(The University of Waikato, 2009)Torrentfish (Cheimarrichthys fosteri Haast 1874) are a freshwater fish species endemic to New Zealand and information pertaining to their general distribution, abundance as well as feeding ecology has been well documented. ...
