Translocation of Evechinus chloroticus in the SUR 5 Fishery and the reproductive potential of large urchins

Thomas, Samuel Frederick (Thesis, Master of Science, 2011)

Evechinus chloroticus (commonly known as Kina) is a commercially important species found in coastal New Zealand waters. Their gonad quality is, however, poor in many regions and thus the areas with high quality gonads tend ...
Characterisation of Compounds Contributing to Kina Roe Colour

Garama, Daniel James (Thesis, Doctor of Philosophy, 2011)

Sea urchin roe is a highly valued product in the international marketplace. New Zealand’s coastal zones, have significant stocks of sea urchin (Evechinus chloroticus; local name Kina), but quality issues including colour, ...
The seasonal biology of the brachiopod Liothyrella neozelanica (Thomson, 1918) from Doubtful Sound, New Zealand.

Baird, Matthew John (Thesis, Master of Science, 2012)

Liothyrella neozelanica (Thomson 1918) (Subphylum: Rhynchonelliformea) is a temperate brachiopod that makes up ecologically important habitat in Doubtful Sound, New Zealand. From December 2010 to December 2011, the seasonal ...
Larval dispersal and population genetic structure of brachiopods in the New Zealand fiords

Ostrow, D. Gigi (Thesis, Doctor of Philosophy, 2004)

New Zealand's fourteen deep-water fiords have complex physical and hydrographic features as well as strong environmental gradients, all of which may influence the population structure of organisms that inhabit the fiords. ...
The effects of UVR and Suncreen Compounds on Sea Urchin Larval Respiration along a Latitudinal Gradient

McCarthy, Alaric (Thesis, Master of Science, 2011)

Sea urchin larvae are particularly vulnerable to enhanced ultraviolet radiation (UVR) exposure as they are small, highly transparent, undergo rapid cell division and occupy the upper regions of the water column. Anthropogenically ...
Conservation biology of bottlenose dolphins in Fiordland, New Zealand

Currey, Rohan J. C. (Thesis, Doctor of Philosophy, 2008)

The bottlenose dolphins of Fiordland, New Zealand, live at the southern limit of the species’ worldwide range. They are exposed to impacts from tourism and habitat modification, particularly in Doubtful Sound, and their ...
Blue cod (Parapercis colias) population structure & connectivity in the New Zealand fjords

Beer, Nicola Anne (Thesis, Doctor of Philosophy, 2011)

Tagging and stable isotopic studies suggest that blue cod (Parapercis colias) in Fiordland form discrete sub-populations at the scale of tens of kilometres with a high degree of residency, particularly in the inner fjord ...
Passive acoustic monitoring of habitat use by bottlenose dolphins in Doubtful Sound

Elliott, Riley Gordon (Thesis, Master of Science, 2011)

In the context of testing the appropriateness of current conservation management, this study used nine moored acoustic monitoring devices (T-PODs) to monitor habitat use by bottlenose dolphins in Doubtful Sound, New Zealand, ...
The lugworm Abarenicola affinis (Arenicolidae, Polychaeta) in tidal flats of Otago, southern New Zealand.

Goerlitz, Stefan (Thesis, Doctor of Philosophy, 2012)

Lugworms (Polychaeta: Arenicolidae) occur in coastal sediments worldwide and can dominate the macrofauna of intertidal sand and mud flats. They have been recognised as ecosystem engineers due to their bioturbating and ...
Distribution and ranging of Hector's dolphins : implications for protected area design

Rayment, William J (Thesis, Doctor of Philosophy, 2008)

The efficacy of a Marine Protected Area (MPA) is contingent on it having a design appropriate for the species it is intended to protect. Hector's dolphin (Cephalorhynchus hectori), a coastal delphinid endemic to New Zealand, ...
