Ivar Rønnestad mainly focuses on Biochemistry, Food science, Endocrinology, Aquaculture and Amino acid. Ivar Rønnestad works mostly in the field of Biochemistry, limiting it down to topics relating to Yolk and, in certain cases, Hatching, Yolk sac and Hippoglossus hippoglossus, as a part of the same area of interest. His biological study spans a wide range of topics, including Assimilation, Live food, Turbot and Incubation.
Ivar Rønnestad combines subjects such as Rainbow trout and Gene expression, Gene with his study of Endocrinology. His Aquaculture research is multidisciplinary, relying on both Ichthyoplankton, Fish larvae, Pelagic zone, Digestion and Nutrient. His research investigates the connection between Metabolism and topics such as Animal science that intersect with issues in Atlantic cod.
The scientist’s investigation covers issues in Biochemistry, Larva, Endocrinology, Food science and Halibut. Amino acid, Metabolism, Catabolism, Digestion and Lysine are the primary areas of interest in his Biochemistry study. His work deals with themes such as Zoology, Juvenile, Fishery and Aquaculture, which intersect with Larva.
His Endocrinology study combines topics from a wide range of disciplines, such as Cholecystokinin and Neuropeptide, Neuropeptide Y receptor, Orexigenic. His Food science study deals with Fish meal intersecting with Plant protein. He usually deals with Halibut and limits it to topics linked to Animal science and Cobia.
Ivar Rønnestad spends much of his time researching Animal science, Endocrinology, Salmo, Cobia and Fish meal. His Endocrinology research incorporates elements of Cholecystokinin, Stomach and Orexigenic. While the research belongs to areas of Cobia, Ivar Rønnestad spends his time largely on the problem of Tropics, intersecting his research to questions surrounding Zoology.
His Zoology study incorporates themes from Acclimatization, Energy balance, Larva and Aquaculture. His research in Fish meal intersects with topics in Food science, Enterohepatic circulation, Bile acid, Pagrus major and Acute effects. His study looks at the relationship between Food science and fields such as Krill, as well as how they intersect with chemical problems.
Ivar Rønnestad mainly focuses on Fish meal, Animal science, Food science, Amino acid and Wrasse. His Fish meal study integrates concerns from other disciplines, such as Pepsin, Enterohepatic circulation, Bile acid, Rainbow trout and Physiology. His Animal science research integrates issues from Pagrus major, Acute effects, Digestive physiology and Methionine.
In his research, Ivar Rønnestad performs multidisciplinary study on Food science and Physiological responses. His Amino acid research includes themes of Cobia, Cholesterol and Metabolism. The Wrasse study combines topics in areas such as Foregut, Cholecystokinin, Receptor, Stomach emptying and Motility.
