Research projects
Customary and ecosystem-based fisheries management
We provide ecological information to complement local and customary knowledge to enable community-based management of coastal fisheries. We work closely with managers of customary fishery areas (e.g. mātaitai and taiāpure) that have been established to allow Māori communities to exercise kaitiakitanga (guardianship) over fisheries and habitats. This work is conducted within the research group Te Tiaki Mahinga Kai (www.mahingakai.org.nz).
Fisheries restoration
We are developing restoration plans for fisheries within customary areas using local resources (e.g. aquaculture facilities) to restore local fisheries that have become depleted due to overfishing and habitat loss. Using Haliotis iris (pāua, abalone) brood stock from the areas being reseeded will allow us to maintain the genetic integrity of local pāua stocks. Research to better understand the ecology of juvenile pāua (key predators, competitors), alongside state-of-the art techniques to trace the success of reseeding will help hone reseeding programmes to maximise success.
Integrated aquaculture
Technology that integrates aquaculture production systems to increase efficiency and reduce environmental impacts will be key in ensuring sustainable growth of aquaculture required to meet ever increasing global demand for marine products. Our research aims to reduce the environmental footprint of aquaculture by growing macroalgae (e.g. kelp) in conjunction with other production systems to reduce pollution while providing a high value crop.
Impacts of elevated CO2 on coastal ecosystems
We use an ecosystem-level approach to predict what changes will occur to complex and variable coastal ecosystems and related fisheries as a result of elevated CO2 (Ocean Acidification). This research uses carefully designed and controlled lab-based experiments alongside quantification the contribution of different groups of species of in coastal ecosystems of today to provide better predictions of likely changes in coastal seas as CO2 concentrations increase.
Ecology and physiology of macroalgae
Macroalgae (seaweeds) are the major primary producers of coastal seas and provide food and habitat that supports coastal food webs and fisheries. Our research focuses on key factors that control primary productivity by macroalgae such as the availability of light and nutrients. Past projects have included investigations into the physiology of deepwater macroalgae and work to determine how water motion influences primary productivity.
Invasion by exotic marine organisms
This research focuses on the invasive kelp Undaria pinnatifida has spread through international shipping from its native range in North East Asia to be found in temperate locations worldwide. We conduct work on the physiology and ecology of this species and its impact on New Zealand's native macroalgal assemblages.
Macroalgal / invertebrate interactions
Waste produced by animals that live on macroalgal surfaces (epifauna) may be an important source of nitrogen that supports macroalgal growth. We use a range of methods to trace nitrogen from epifauna into macroalgae to determine the contribution of recycled nitrogen from epifauna to coastal primary productivity.
