A meta-analysis of plaice size-selection data in otter trawl codends
(Journal article; Peer reviewed, 2020-07)The influence that mesh size, the number of open meshes around the circumference, twine thickness and catch size have on the size-selection of plaice (Pleuronectes platessa) in otter trawl codends is investigated by ... -
Assessing the impact of buffer towing on the quality of Northeast Atlantic cod (Gadus morhua) caught with a bottom trawl
(Journal article; Peer reviewed, 2018-10)The dense aggregations of Northeast Atlantic cod (Gadus morhua) in the Barents Sea have led to a new fishing practice termed “buffer towing.” In this fishery, many trawlers redeploy the trawl directly after taking the catch ... -
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; Peer reviewed, 2019-11)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 ... -
Can active behaviour stimulators improve fish separation from Nephrops (Nephrops norvegicus) in a horizontally divided trawl codend?
(Journal article; Peer reviewed, 2018-03)A promising design to improve selectivity in the Nephrops-directed trawl fishery is the horizontally divided trawl codend. Previous studies have succeeded in separating the majority of fish from Nephrops; however, cod ... -
The capability of square-meshes and fixed-shape meshes to control codend size selection
(Journal article; Peer reviewed, 2023)Trawl codends are commonly made of diamond-mesh netting. However, diamond-mesh codends vary in mesh geometry along its length and during fishing due to catch build up. This introduces variability in the size selection ... -
Comparing size selectivity of traditional and knotless diamond-mesh codends in the Iceland redfish (Sebastes spp.) fishery
(Journal article; Peer reviewed, 2019-08)The size selectivity and usability of two diamond mesh codends, a traditional two-panel codend versus an experimental four-panel ultra-cross knotless mesh codend, were compared using the covered codend method in the Iceland ... -
Comparison of fishing efficiency between biodegradable gillnets and conventional nylon gillnets
(Journal article; Peer reviewed, 2019-05)Gillnets made of a new biodegradable resin (polybutylene succinate co-adipate-co-terephthalate (PBSAT) were tested under commercial fishing conditions to compare their fishing performance with that of conventional nylon ... -
Could green artificial light reduce bycatch during Barents Sea Deep-water shrimp trawling?
(Journal article; Peer reviewed, 2018-08)The Nordmøre grid is widely used in shrimp trawls to reduce the bycatch of fish species. However, small-sized fish species and juveniles still pass through the grid and enter the codend, along with the targeted shrimp. ... -
CREELSELECT—A method for determining the optimal creel mesh: Case study on Norway lobster (Nephrops norvegicus) fishery in the Mediterranean Sea
(Journal article; Peer reviewed, 2018-08)In the laboratory, we investigated which sizes of Nephrops (Nephrops norvegicus) could pass through the meshes of different size and shape to establish a predictive model for the creels size selectivity. Predictions agreed ... -
Dredge selectivity in a Mediterranean striped venus clam (Chamelea gallina) fishery
(Peer reviewed; Journal article, 2021)The striped venus clam Chamelea gallina is the target of a large fleet of hydraulic dredgers, which represent an important fishing sector in terms of income and landings in the Mediterranean Sea. Although there is information ... -
Effect of gear soak time on size selection in the snow crab pot fishery
(Journal article; Peer reviewed, 2019-06)In the commercial pot fishery for snow crab (Chionocetes opilio), size selection by the pots is important for reducing catch sorting and unintended mortality. In addition to mesh size and shape, selection in the pots relies ... -
Effect of three different codend designs on the size selectivity of juvenile cod in the Barents Sea shrimp trawl fishery
(Journal article; Peer reviewed, 2019-11)Shrimp trawlers often use a Nordmøre sorting grid ahead of a small mesh codend to avoid bycatch of juvenile fish while allowing shrimps to be efficiently caught. However, small fish can pass through the grid to enter the ... -
Evaluating off-bottom sweeps of a U.S. West Coast groundfish bottom trawl: Effects on catch efficiency and seafloor interactions
(Journal article; Peer reviewed, 2019-05)In the U.S. West Coast groundfish bottom trawl fishery, lengthy sweeps (>85 m) that maintain seafloor contact are traditionally used. While these sweeps are effective at herding groundfishes, their bottom tending characteristics ... -
External damage to trawl-caught Northeast arctic cod (Gadus morhua): Effect of codend design
(Journal article; Peer reviewed, 2019-06)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 ... -
Increasing catch efficiency for Nephrops in deep-water shrimp (Pandalus borealis) trawl fisheries
(Peer reviewed; Journal article, 2022)In Skagerrak and the North Sea, coastal vessels harvest deep-water shrimp (Pandalus borealis) in a mixed fishery, in which catches of Nephrops (Nephrops norvegicus) are of economic importance for the fleet. Fishermen ... -
Is there a limit to the potential effects of shortening lastridge ropes on the size selectivity of diamond mesh codends?
(Journal article; Peer reviewed, 2023)Shortening codend lastridge ropes can be an effective fishing gear modification to improve the size selection properties in diamond mesh codends. Lastridge ropes attached to codend selvedges withstand the longitudinal ... -
Shrimp trap selectivity in a Mediterranean small-scale-fishery
(Journal article; Peer reviewed, 2019-03)Small-scale shrimp trap fisheries, which have received very little attention in areas with limited potential for economic diversification, could offer a sustainable and socially beneficial option for profitable businesses ... -
Size selection of Antarctic krill (Euphausia superba) in a commersial codend and trawl body
(Journal article; Peer reviewed, 2018-11)During fishing, many fish species are able to avoid the net walls of the trawl body and so the majority of size selection occurs in the codend of the net. Antarctic krill (Euphausia superba) are regarded as true planktonic ... -
Size selection of cod (Gadus morhua) and haddock (Melanogrammus aeglefinus) in the Northeast Atlantic bottom trawl fishery with a newly developed double steel grid system
(Journal article; Peer reviewed, 2018-05)In recent years, Norwegian fishermen have reported problems with fish accumulation in front of the mandatory sorting grids (Sort-X, Sort-V, and Flexigrid). These problems are associated with high fish entry rates and low ... -
Size selectivity and catch efficiency of bottom trawl with a double sorting grid and diamond mesh codend in the North-east Atlantic gadoid fishery
(Journal article; Peer reviewed, 2020-11)This study investigated the size selectivity and catch efficiency in the North-east Atlantic demersal trawl fishery targeting cod (Gadus morhua) and haddock (Melanogrammus aeglefinus). The use of a sorting grid followed ...
