  • Dr Norman Ragg

    Research Scientist – Shellfish Biology and Physiology

    Role at Cawthron

    Norman leads the physiology team at Cawthron, drawing on a background of work in the aquaculture industry combined with training as a classical biologist focusing on physiology. This is brought to bear in a range of projects where the physiology of aquaculture species is a key issue, such as:

    • Quantifying stress and resilience in shellfish

    • Mitigating the effects of ocean acidification and warming: building resilience in the aquaculture industry

    • Identifying resource-efficient shellfish families for use in selective breeding

    • Optimising hatchery processes

    • Enhancing meat quality and yield through good harvest practice and transport technology

    Technical skills, experience and interests

    • Introduction of physiological tools and scientific discipline to optimise the effectiveness of aquaculture research

    • Integration of selective breeding with physiological performance parameters

    • Climate change simulation and mitigation

    • Baseline biological description of novel aquaculture species

    • True sustainability in the primary industry, minimising or even eliminating net environmental impact while optimising productivity
