Overview

What is he best known for?

The fields of study he is best known for:

  • Gene
  • Enzyme
  • Biochemistry

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.

His most cited work include:

  • Fish larval nutrition: a review of recent advances in the roles of amino acids (264 citations)
  • Feeding behaviour and digestive physiology in larval fish: current knowledge, and gaps and bottlenecks in research (200 citations)
  • Fish larval nutrition and feed formulation - knowledge gaps and bottlenecks for advances in larval rearing (195 citations)

What are the main themes of his work throughout his whole career to date?

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.

He most often published in these fields:

  • Biochemistry (35.98%)
  • Larva (24.34%)
  • Endocrinology (23.28%)

What were the highlights of his more recent work (between 2017-2021)?

  • Animal science (17.46%)
  • Endocrinology (23.28%)
  • Salmo (6.88%)

In recent papers he was focusing on the following fields of study:

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.

Between 2017 and 2021, his most popular works were:

  • Loss of stomach, loss of appetite? Sequencing of the ballan wrasse ( Labrus bergylta ) genome and intestinal transcriptomic profiling illuminate the evolution of loss of stomach function in fish (21 citations)
  • Effects of dietary soybean meal on the digestive physiology of red seabream Pagrus major (18 citations)
  • Effect of increased rearing temperature on digestive function in cobia early juvenile. (10 citations)

In his most recent research, the most cited papers focused on:

  • Gene
  • Enzyme
  • Biochemistry

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.
