Modulation of intestinal growth and differentiation by photoperiod and dietary treatment during smoltification in Atlantic salmon (Salmo salar, L.)
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-12-15)Atlantic salmon undergo smoltification, a process that prepares the fish to enter and thrive in seawater (SW). Several physiological changes occur during smolting, especially in osmoregulatory tissues, the gill, the kidney, and the intestine. Here we characterized the effects on intestinal morphogenesis of two different, commonly used smoltification regimes during the end of the freshwater phase, ... -
Big business returns on B Corp? Growing with green & lean as any label is a good label
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-10-25)This current research contributes to the concept of consumer-based food label equity (CBFLE) by testing the predictive validity of a scale developed by Coderre et al. (2022) in the sustainability and health domains of seafood products. In Study 1 (N = 301; between-within subjects), we found that scores on all subscales, except the (Dis)honesty subscale, were significantly related to willingness to ... -
