DNA and scale reading to identify repeat spawning in Atlantic salmon: Unique insights into patterns of iteroparity
(Journal article; Peer reviewed, 2023)Iteroparity represents an important but often overlooked component of life history in anadromous Atlantic salmon. Here, we combined individual DNA profiling and scale reading to identify repeat spawners among ~8000 adult ... -
Real-time prediction of fish cage behaviors under varying currents using deep neural network
(Chapter, 2023)This paper presents a Deep Neural Network (DNN) model for rapid and low-cost prediction of fish cage behavior under varying currents. We employ a numerical model of the fish cage created in Orcaflex and a set of current ... -
Use of industry 4.0 technologies to reduce and valorize seafood waste and by-products: A narrative review on current knowledge
(Peer reviewed; Journal article, 2023)Fish and other seafood products represent a valuable source of many nutrients and micronutrients for the human diet and contribute significantly to global food security. However, considerable amounts of seafood waste and ... -
The Effects of Enzymes, Species, and Storage of Raw Material on Physicochemical Properties of Protein Hydrolysates from Whitefish Heads
