Katarina Doughty

Katarina Doughty is a Lecturer in Aquaculture/Aquatech at the UWA School of Agriculture and Environment, The University of Western Australia. Her research focuses on sustainable food systems, particularly using black soldier fly (Hermetia illucens) protein in aquaculture diets to address waste management and food security challenges. She holds a MSc and BSc Hons from Western University, specializing in salmon nutrition and crossbreeding impacts.

Education:

• MSc in Biology: The effects of crossbreeding and low fish meal diets on growth-related traits in Chinook salmon (2014–2017)
• BSc Hons in Biology (2014)

Her work aligns with UN Sustainable Development Goals, emphasizing waste reduction and sustainable aquaculture practices. Key projects include trials evaluating insect-meal inclusion levels in trout diets and optimizing aquaculture practices under climate change. She has secured grants such as the Science Industry PhD Fellowship and led projects like 'Adapting Aquaculture: Innovative Responses for Sustainable Food Security' (2024–2025).

Research Highlights:

• Developing insect-based aquafeeds to reduce environmental impact
• Assessing salinity and temperature effects on rainbow trout growth
• Pioneering circular bioeconomy models for food production

Awards & Recognition:

• Science Industry PhD Fellowship (2019)
• Three Minute Thesis Award (2019)

Her work has been featured in media such as TEDx and articles in Cleaner and Circular Bioeconomy. She collaborates internationally on topics like fish feed innovation and sustainable food systems.
