Harvesting Strategies in a Fish Stock Dominated by Low-frequency Variability: The Norwegian Spring-spawning Herring (Clupea harengus)
(Journal article; Peer reviewed, 2003)Heavy positively autocorrelated natural fluctuations in a fisheries stock level are problematic for fisheries management, and collapses in the stock dynamics are difficult to avoid. In this paper, we compare three different ... -

Heads and tails: The notochord develops differently in the cranium and caudal fin of Atlantic Salmon (Salmo salar, L.)
(Peer reviewed; Journal article, 2020)While it is well known that the notochord of bony fishes changes over developmental time, less is known about how it varies across different body regions. In the development of the Atlantic salmon, Salmo salar L., cranial ... -
Health survey of selected stocks of commercially exploited Norwegian bivalve molluscs
(Journal article; Peer reviewed, 1993-08-05)This paper describes the first systematic health survey of commercially exploited bivalve molluscs in Norway. The main aim of the work was to screen selected stocks of the native flat oyster Ostrea edulis and the introduced ... -
Heart rate bio-loggers as welfare indicators in Atlantic salmon (Salmo salar) aquaculture
(Peer reviewed; Journal article, 2020)In this study, 12 farmed Atlantic salmon (~1200 g) were tagged with commercially available heart rate (HR) bio-loggers and maintained in a controlled fish tank laboratory environment at 9 °C on a 12 h day/night cycle for ... -
Heat content in the Norwegian Sea, 1995–2010
(Journal article; Peer reviewed, 2012-02-26)Spatio-temporal hydrographic data from the Nordic Seas during spring over the period 1995–2010 were investigated in terms of the relative heat content (RHC) above the density surface σt = 27.9, chosen to capture the changes ... -
Heat in the Barents Sea: transport, storage, and surface fluxes
(Journal article; Peer reviewed, 2010)A column model is set up for the Barents Sea to explore sensitivity of surface fluxes and heat storage from varying ocean heat transport. Mean monthly ocean transport and atmospheric forcing are synthesised and force the ... -
Hepatic EROD activity in dab Limanda limanda the German Bight using an improved plate-reader method
(Journal article; Peer reviewed, 1992-12-31)During the Bremerhaven Workshop an improved, fast and easy method for the determination of ethoxyresorufin-O-deethylase (EROD) activity in dab Limanda limanda liver was tested. The improvement involved the use of a 12500 ... -
Hepatotoxic pyrrolizidine alkaloids induce DNA damage response in rat liver in a 28-day feeding study
(Peer reviewed; Journal article, 2020)Pyrrolizidine alkaloids (PA) are secondary plant metabolites that occur as food and feed contaminants. Acute and subacute PA poisoning can lead to severe liver damage in humans and animals, comprising liver pain, hepatomegaly ... -
Herring tilt angles, measured through target tracking
(Report / Alaska Sea Grant College Program, Chapter, 2001)The target strength of herring in captivity was monitored experimentally at three frequencies (18, 38, and 120 kHz) over a period of 3 years using split-beam echo sounders. One of the fundamental parameters of a target ... -
Heterochiasmy and the establishment of gsdf as a novel sex determining gene in Atlantic halibut
(Peer reviewed; Journal article, 2022)Atlantic Halibut (Hippoglossus hippoglossus) has a X/Y genetic sex determination system, but the sex determining factor is not known. We produced a high-quality genome assembly from a male and identified parts of chromosome ... -
Heterogeneity on the abyssal plains: A case study in the Bering Sea
(Peer reviewed; Journal article, 2023)The abyssal plains are vast areas without large scale relief that occupy much of the ocean floor. Although long considered relatively featureless, they are now known to display substantial biological heterogeneity across ... -
Hierarchical genetic structure in an evolving species complex: Insights from genome wide ddRAD data in Sebastes mentella
(Peer reviewed; Journal article, 2021)The diverse biology and ecology of marine organisms may lead to complex patterns of intraspecific diversity for both neutral and adaptive genetic variation. Sebastes mentella displays a particular life-history as livebearers, ... -
