Understanding and predicting size selection in diamond-mesh cod ends for Danish seining: a study based on sea trials and computer simulations
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-06-28)
Danish seining is an important fishing method used to harvest demersal species. Knowledge about the size selectivity of different demersal species with this type of fishing gear is therefore of importance for managing the exploitation of marine resources. However, there are only limited data on size selection in cod ends in this fishery. Sea trials were therefore carried out to collect size selectivity ...
When is enough, enough? Quantifying trade-offs between information quality and sampling effort for fishing gear selectivity data
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-06-21)
There is general pressure throughout the world’s fisheries for the industry to have greater involvement not only in the development of fishing gears but also in the testing and documentation of their effect. In the European Union, the Common Fisheries Policy of 2013, together with the proposed reform of the technical measures regulation, highlights the need for greater flexibility in fisheries through ...
Does the efficiency of a counter-herding device depend on seabed contact?
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-07-06)
To prevent unwanted fish bycatch from entering the trawl, we modified a counter-herding device, FLEXSELECT, developed for a Northeast Atlantic <i>Nephrops</i> (<i>Nephrops norvegicus</i>) trawl fishery. FLEXSELECT, which was designed to direct fish away from the trawl by means of sweeping ropes in the herding area, has been shown to be highly effective on both roundfish and flatfish species. However, ...
A netting-based alternative to rigid sorting grids in the small-meshed Norway pout (Trisopterus esmarkii) trawl fishery
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-01-28)
A new bycatch reduction device, termed “Excluder”, is presented as an alternative to a traditional rigid sorting grid, mandatory in the small-meshed Norway Pout (<i>Trisopterus esmarkii</i>) trawl fishery in the North Sea. The fishery is a high-volume fishery with large vessels, large demersal trawls and catches up to 100 tons per haul of this small forage fish. The Excluder is a 30 m long netting-based ...
