Future proofing NZ seafood production through the domestication of iconic NZ species: The role of research in the development of customised hatchery and farming technologies

Dr Leo Zamora

The NZ aquaculture industry currently relies on the commercial production of three species, making the sector particularly susceptible to environmental and biological challenges as well as to market volatility. Therefore, the diversification of the aquaculture species portfolio represents a recognised avenue to manage and reduce risk while enhancing farm production yields. However, there is currently a lack of understanding of key variables for the species of interests to help them transition faster from promise to reality.

This presentation will introduce some key research examples of how we are addressing some of these species-specific bottlenecks in the context of hatchery seed production as well as single- and multi-species farming. Depending on the species, the impact of the research can go beyond aquaculture and can even inform restoration and stock management initiatives.

Physiological mechanisms underpinning shellfish resilience to environmental stress

Dr Natali Delorme

Understanding the physiological mechanisms that govern shellfish responses to environmental stressors is essential for predicting performance and resilience under changing ocean conditions. This presentation will outline shellfish physiology research at the Cawthron Institute, with a focus on oxidative stress responses and thermal tolerance in the context of climate change. Using selected research examples, I will demonstrate how biochemical, molecular, and organism-level approaches are applied to link mechanistic responses to variation in stress tolerance and performance.

The presentation will highlight collaborative research with the University of Otago, demonstrating how integrating fundamental physiology with applied aquaculture questions enhances research impact.
