A bio-economic analysis of harvest control rules for the Northeast Arctic cod fishery
(Journal article; Peer reviewed, 2012-12-12)Harvest control rules (HCRs) have been implemented for many fisheries worldwide. However, in most instances, those HCRs are not based on the explicit feedbacks between stock properties and economic considerations. This ... -
An evaluation of the bottom trawl surveys in the Benguela Current Large Marine Ecosystem
(Journal article; Peer reviewed, 2014-07-02)Demersal fish, shrimp and cephalopod assemblages on the continental shelves and slopes off Angola, Namibia and the southern and western coasts of South Africa have been monitored in terms of fisheries-independent trawl ... -
Benefits of threshold strategies and age-selective harvesting in a fluctuating fish stock of Norwegian spring spawning herring Clupea harengus
(Journal article; Peer reviewed, 2005-08-15)The current state of the world’s fisheries resources requires further investigation into the means and methods for sustainable use of fish stocks. In this study, I assess the performance of different harvesting strategies ... -
Day and night fish distribution pattern in the net mouth area of the Norwegian bottom-sampling trawl
(Journal article; Peer reviewed, 1990)A high-frequency scanning sonar, mounted as a net sonde, was used to study fish behaviour in the mouth area of the Norwegian bottom-sampling trawl. Fish distribution patterns were significantly different by day and night. ... -
Fishery for goldsinny wrasse (Ctenolabrus rupestris) (Labridae) with pots along the Norwegian Skagerrak coast
(Journal article; Peer reviewed, 2002-03)Goldsinny wrasse (Ctenolabrus rupestris) was captured in pots during the years 1994-98 in the area between Arendal and Homborsund, west of Grimstad, along the Norwegian Skagerrak coast. The pots, made of steel 1 x 1 cm ... -
Improving management decisions by predicting fish bycatch in the Barents Sea shrimp fishery
(Journal article; Peer reviewed, 2011-11-20)When the bycatch of juvenile fish within the Barents Sea shrimp fishery is too large, the area is closed to fishing for a certain period. Bycatch is estimated from sampled trawl hauls, for which the shrimp yield is recorded, ... -
Mortality of mackerel (Scomber scombrus L.) after pursing and slipping from a purse seine
(Journal article; Peer reviewed, 2010-10)A new method was used to study the effect of crowding and subsequent slipping from a purse seine on the mortality of Atlantic mackerel (Scomber scombrus L.). Mackerel were allowed to swim from a purse seine through a ... -

Probability-based surveying using self-sampling to estimate catch and effort in Norway’s coastal tourist fishery
(Journal article; Peer reviewed, 2011-06-08)Recreational fishing as a tourist activity has become an increasingly important part of the Norwegian travel industry and may contribute significantly to the fishing mortality on Norwegian coastal cod (Gadus morhua). ... -
The “Discard Ban Package”: Experiences in efforts to improve the exploitation patterns in Norwegian fisheries
(Journal article; Peer reviewed, 2015-01-09)A source to long-term increased catches and profitability for the fishing fleet is the reduction of discards and improvements in exploitation patterns. This article details the development of Norwegian regulatory measures ... -
Thermal niche of Atlantic cod Gadus morhua: limits, tolerance and optima
(Journal article; Peer reviewed, 2010)Recent studies in the marine environment have suggested that the limited phenotypic plasticity of cold-adapted species such as Atlantic cod Gadus morhua L. will cause distributions to shift toward the poles in response to ... -
Total Catch of a Red-Listed Marine Species Is an Order of Magnitude Higher than Official Data
(Journal article; Peer reviewed, 2012-02-17)Accurate information on total catch and effort is essential for successful fisheries management. Officially reported landings, however, may be underestimates of total catch in many fisheries. We investigated the fishery ...
