Professor Ivar Rønnestad has a background in human and comparative physiology. Early in his career, he worked on thermal regulation and respiratory adaptations in divers, focusing on the physiological mechanisms that enable humans to function in extreme environments, such as deep-sea diving operations down to 360m. Rønnestad was involved in trials that led to the development of Norway's first designed deep sea breathing system (OBS).

Rønnestad's transition to fish physiology allowed him to apply his understanding of comparative physiology, metabolic regulation, and adaptive mechanisms to improve knowledge on fish development, feeding behavior, growth, and environmental adaptations. His expertise in these areas facilitated significant advancements in understanding of the nutritional physiology of fish.

Since 1988, his primary research interest has been the nutritional and digestive physiology of teleost fish. Currently, he focuses on digestion and appetite regulation, specifically the gut-brain axis, and how it relates to growth and energy homeostasis. While his current main species of study is Atlantic salmon, Rønnestad has extensive experience with other aquaculture species.

In the following key areas, Professor Rønnestad's research contributes to both fundamental science and practical aquaculture improvements:

• Digestive Physiology and Feeding Behavior in Larval Fish: His early work on teleosts explored the digestive processes in larval fish, including nutrient digestion, absorption, and the functional development of their digestive systems from first feeding through metamorphosis. These studies aim to improve feeding protocols and enhance larval survival in aquaculture.
• Fish Growth and Metabolism: His current research emphasizes the molecular and physiological mechanisms underlying appetite, digestion, feed intake, and growth in fish. A key focus is on understanding appetite control and gut-brain axis signaling pathways, particularly how gut-derived signals like hormones communicate with the brain to regulate hunger and satiety. This research is crucial for optimizing feed intake, improving growth rates, and enhancing sustainability in aquaculture.
• Melanocortin System and Appetite control: One significant aspect of his work involves studying neuropeptides in the melanocortin system, which is involved in appetite control. His group has mapped key neuropeptides in fish such as Atlantic salmon, linking them to feeding behavior and energy homeostasis. This research contributes to more efficient aquaculture practices by optimizing growth, improving feed conversion ratios, and reducing waste.
• Aquaculture and Sustainability: Rønnestad is also involved in projects aimed at improving the sustainability of aquaculture, focusing on developing alternative feed ingredients (e.g., fishmeal replacements) and investigating the impacts of environmental changes such as global warming on fish health and production.
• Gas Bubble Disease in Fish: Drawing from his early work on diving physiology, Rønnestad has applied similar physiological principles to his recent research involvement on gas bubble disease in Atlantic salmon. This condition, related to gas supersaturation, mirrors challenges seen in diving physiology and is crucial for improving operational procedures to mitigate mortalities and welfare issues in aquaculture.

Overall, Professor Rønnestad’s work contributes to both the scientific understanding of fish physiology and the development of practical solutions for enhancing aquaculture efficiency and sustainability.

Ivar Rønnestad is currently mainly involved in teaching in BIO104 (Comparative physiology) and BIO291 (Fish Biology II- Physiology) in addition to supervision of Master, PhD and Postdoc candidates. He is the leader of the ExcelAQUA Summer school that is a collaboration between University of Bergen, NORCE and seven Universities and Research Institutes in Japan. Students and faculty from USA and Canada also participate in the Summer school.

Through BioCEED he collaborates with Educational Researchers Sehoya Cotner and Seth Thompson at University of Minnesota.

He received the Olav Thon Foundation National award for outstanding teaching in 2019.
