Effect of a quality-improving codend on size selectivity and catch patterns of cod in bottom trawl fishery
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-02-26)
A new codend concept developed and tested exhibited significantly improved quality of caught cod (<i>Gadus morhua</i>) compared to that of the conventional codend used in the Barents Sea bottom trawl fishery. However, the design of the new quality-improving codend raised concerns about its size selectivity and the possibility that higher retention probability could negatively impact the catch pattern ...
External damage to trawl-caught Northeast arctic cod (Gadus morhua): Effect of codend design
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-02-22)
The purpose of this study was to investigate the extent of external damage (gear marks, pressure injuries, ecchymosis and skin abrasion) present on trawl-caught cod (Gadus morhua) and to examine whether the extent of damage could be reduced by introducing changes in the gear. We tested whether changing the 2-panel knotted codend used by the Norwegian trawler fleet operating in the Barents Sea today ...
Can a large-mesh sieve panel replace or supplement the Nordmøre grid for bycatch mitigation in the northeast Atlantic deep-water shrimp fishery?
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-07-26)
The Nordmøre grid is the principle bycatch mitigation device in many shrimp trawl fisheries. However, in several of these fisheries, bycatch is a problem because small sized fish can pass through the grid and enter the codend together with the targeted shrimp. One such fishery is the Northeast Atlantic deep-water shrimp (<i>Pandalus borealis</i>) fishery, where the use of a Nordmøre grid is mandatory. ...
