Catch-and-release of Atlantic cod (Gadus morhua) in recreational fisheries
Ferter, Keno (Doctoral thesis, 2015-06-26)The role of recreational fisheries in the exploitation pressure on fish resources is increasingly recognized. This has led to the introduction of new harvest regulations for several European marine recreational fisheries. ... -
Catch-and-release of Atlantic cod (Gadus morhua): post-release behaviour of acoustically pretagged fish in a natural marine environment
Ferter, Keno; Klaas, Hartmann; Kleiven, Alf Ring; Moland, Even; Olsen, Esben Moland (Peer reviewed; Journal article, 2014-10-07)Studying the sublethal effects of catch-and-release (C&R) is challenging, as there are several potential sources of bias. For example, if behavioural alterations immediately after the release event are to be studied, ... -
The comeback of Atlantic bluefin tuna (Thunnus thynnus) to Norwegian waters
Nøttestad, Leif; Boge, Erling; Ferter, Keno (Journal article; Peer reviewed, 2020)We document that Atlantic bluefin tuna (BFT) began making a comeback from 2012 onwards into Norwegian waters, after several decades of absence, in parallel with an overall increased abundance recorded for eastern BFT. This ... -
Dive to survive: effects of capture depth on barotrauma and post-release survival of Atlantic cod (Gadus morhua) in recreational fisheries
Ferter, Keno; Weltersbach, Marc Simon; Humborstad, Odd Børre; Fjelldal, Per Gunnar; Sambraus, Florian; Strehlow, Harry Vincent; Vølstad, Jon Helge (Peer reviewed; Journal article, 2015-06-04)Atlantic cod (Gadus morhua) caught in recreational fisheries are commonly released, often with barotrauma after rapid decompression. Mouth-hooked, non-bleeding cod kept in a floating net pen showed mortalities ≥40% when ... -
Hook shedding and post-release fate of deep-hooked European eel
Weltersbach, Marc Simon; Ferter, Keno; Sambraus, Florian; Strehlow, Harry Vincent (Peer reviewed; Journal article, 2016-07)The European eel (Anguilla anguilla) is a commercially and recreationally important fishery target species. In the last decades, the eel has experienced dramatic stock declines and has been listed as critically endangered. ... -
Targeted risk assessment of mercury exposure of recreational fishers: Are nephrops fishers in Norway at risk?
Wiech, Martin; Djønne, Christine; Kolding, Jeppe; Kjellevold, Marian; Ferter, Keno (Journal article; Peer reviewed, 2021)Recreational fishers often consume their catch, which may expose them to environmental contaminants. However, targeted risk assessment for exceeding the tolerable weekly intake (TWI) of a specific contaminant is often ... -
Towards more efficient longline fisheries: fish feeding behaviour, bait characteristics and development of alternative baits
Løkkeborg, Svein; Siikavuopio, Sten Ivar; Humborstad, Odd Børre; Utne-Palm, Anne Christine; Ferter, Keno (Peer reviewed; Journal article, 2014-12)Better knowledge of food search behavior in fish is essential for studies that aim to improve longline fishing, particularly through bait development. This review provides an overview of our understanding of how fish detect ...
