Quality assessment of Atlantic cod (Gadus morhua) caught by longlining and trawling at the same time and location

Survival and recovery of longline- and pot-caught cod (Gadus morhua) for use in capture-based aquaculture (CBA)

“…However, both are believed to be benign gears, since fish in the catch are often alive and their flesh quality is high, indicative of low capture stress (Botta et al, 1987a,b;Rotabakk et al, 2011;Suuronen et al, 2012;Thomsen et al, 2010). Midling et al (2005) showed that survival rates of longline-caught cod could be as high as 95% in transport tanks, given good sorting.…”

Capture induced stress and live storage of Atlantic cod (Gadus morhua) caught by trawl: Consequences for the flesh quality

“…Typical quality defects for cod caught by bottom trawl and Danish seine are bruises and muscle discoloration due to insufficient exsanguination. The bruises can be linked to pressure in the trawl and tough handling of the fish before it is bled (Digre et al, 2010;Rotabakk et al, 2011). Regarding Danish seiners and trawlers, it has been suspected that weather conditions, duration and size of the haul also may affect the quality of the catch (Margeirsson et al, 2007).…”

Testing the effect of soak time on catch damage in a coastal gillnetter and the consequences on processed fish quality

“…Instead, previous studies have used semi-quantitative indices of individual fish condition grouped in an index to evaluate whole or processed fish damage in fishing gears (Depestele, Desender, Benoît, & Polet, 2014;Digre, Hansen, & Erikson, 2010;Digre, Tveit, SolvangGarten, Eilertsen, & Aursand, 2016;Karlsen, Krag, Albertsen, & Frandsen, 2015;Olsen, Tobiassen, Akse, Evensen, & Midling, 2013;Rotabakk, Skipnes, Akse, & Birkeland, 2011). Most studies used hypothesis testing which does not allow for the estimation of the size of effects, unlike model-based methods such as cumulative link mixed modelling which is appropriate for ordinal multi-category responses.…”
