Anorectic role of high dietary leucine in farmed Atlantic salmon (Salmo salar L.): Effects on feed intake, growth, amino acid transporters and appetite-control neuropeptides.
(Peer reviewed; Journal article, 2023)Leucine has been identified to modulate feed intake and energy homeostasis in fish as in other vertebrates. Under allostatic conditions, energy expenditure may change, and adjustments to the processes that govern the energy ... -
Another Decade of Marine Climate Change Experiments: Trends, Progress and Knowledge Gaps
(Peer reviewed; Journal article, 2021)Anthropogenic climate change is a significant driver of change in marine ecosystems globally. To improve mechanistic understanding of the impact of climate-related stressors, experimental work on marine organisms has ... -
Antarctic krill (Euphausia superba) catch weight estimated with a trawl-mounted echosounder during fishing
(Peer reviewed; Journal article, 2023)Reporting reliable catch weight estimates is important for all fisheries management. This study explores the potential for precise and direct estimation of catch weight (green weight) for the Antarctic krill (Euphausia ... -
Antarctic krill (Euphausia superba) exhibit positive phototaxis to white LED light
(Peer reviewed; Journal article, 2021)The use of light-emitting diodes (LEDs) is increasingly used in fishing gears and its application is known to trigger negative or positive phototaxis (i.e., swimming away or toward the light source, respectively) for some ... -
