Determinants of mean length at age of spring spawning herring off the coast of Hokkaido, Japan
(Journal article; Peer reviewed, 2008-08-29)The stock of Hokkaido spring spawning herring Clupea pallasii collapsed in the middle of the 20th century. In the first half of the 20th century, large amounts of spawning herring were caught by set nets at coastal ... -
Development of eleven microsatellite loci in the deep-sea black scabbardfish (Aphanopus carbo)
(Journal article; Peer reviewed, 2009-06)We developed 11 microsatellite loci primers in the bathypelagic black scabbardfish (Aphanopus carbo), a novelty for deep-sea fishes. All markers were obtained from partial genomic DNA libraries enriched for tetranucleotide ... -
Development of ten microsatellite loci in the marine fish ling (Molva molva)
(Journal article; Peer reviewed, 2009-09)We developed primers for two dinucleotide and eight tetranucleotide microsatellite loci in a marine fish, the ling (Molva molva). All markers were obtained from partial genomic DNA libraries and characterized in 55 unrelated ... -
Development of twelve microsatellite loci in the corkwing wrasse (Symphodus melops)
(Journal article; Peer reviewed, 2010)We developed 12 microsatellite loci primers in 8 the corkwing wrasse (Symphodus melops). All markers 9 were obtained from partial genomic DNA libraries enri-10 ched for tetranucleotide repeats and characterized in 32 11 ... -
Different Dietary Levels of Protein to Lipid Ratio Affected Digestive Efficiency, Skeletal Growth, and Muscle Protein in Rainbow Trout Families
(Journal article; Peer reviewed, 2009)Normal Protein (NP) and High Protein (HP) diets were provided to rainbow trout families from juvenile to maturity. Muscle protein concentration increased during growth and the protein to lipid (P/L) ratio was doubled at ... -
Differential responses of three sympatric seabirds to spatio-temporal variability in shared resources
(Journal article; Peer reviewed, 2012-11-14)Environmental change linked to climate and human activities may affect top predators via the food chain in marine systems. Understanding the functional link between resources and predator responses (e.g. foraging effort, ... -
Diseases of farmed Atlantic salmon Salmo salar associated with infections by the microsporidian Paranucleospora theridion
(Journal article; Peer reviewed, 2011-03-16)The microsporidian Paranucleospora theridion was discovered in Atlantic salmon Salmo salar suffering from proliferative gill disease in a marine farm in western Norway in 2008. The parasite develops in cells of the ... -
Distribution and density of goldsinny wrasse (Ctenolabrus rupestris) (Labridae) in the Risør and Arendal areas along the Norwegian Skagerrak coast
(Journal article; Peer reviewed, 2002-03)Samples of fish were collected in the Arendal and Risør areas on the Norwegian Skagerrak coast during the period 1986 to 1990 using a beach seine at 36 different locations. In the Risør area, 131 out of 254 hauls yielded ... -
Do accurate stock estimates increase harvest and reduce variability in fisheries yields?
(Journal article; Peer reviewed, 2011-03-22)Fisheries managers normally make decisions based on stock abundance estimates subject to process, observation, and model uncertainties. Considerable effort is invested in gathering information about stock size to decrease ... -
Does Presence of a Mid-Ocean Ridge Enhance Biomass and Biodiversity?
(Journal article; Peer reviewed, 2013-05-02)In contrast to generally sparse biological communities in open-ocean settings, seamounts and ridges are perceived as areas of elevated productivity and biodiversity capable of supporting commercial fisheries. We investigated ... -
Does size matter? A bioeconomic perspective on optimal harvesting when price is size-dependent
(Journal article; Peer reviewed, 2011-09-09)Body size is a key parameter influencing demographic characteristics of fish populations as well as market value of landed catch. Yet in bioeconomic modelling, body size is often an overlooked biological and economic ... -
Dynamics of shallow-water juvenile flatfish nursery grounds: application of the self-thinning rule
(Journal article; Peer reviewed, 2007-08-23)Annual development of density and mean weight of juvenile plaice Pleuronectes platessa was examined at 2 nursery grounds (Port Erin Bay, Isle of Man, Irish Sea and Admucknish Bay, Firth of Lorne, west coast of Scotland) ... -
The ecology of recovery
(Journal article; Peer reviewed, 2003-04-30)The current high rate of population declines and attempts to `manage' their recovery, call for a better understanding of recovery dynamics of populations. In many cases, recovery of a population may primarily be determined ... -
Effect of Sub-Lethal Exposure to Ultraviolet Radiation on the Escape Performance of Atlantic Cod Larvae (Gadus morhua)
(Journal article; Peer reviewed, 2012-04-19)The amount of ultraviolet (UV) radiation reaching the earth’s surface has increased due to depletion of the ozone layer. Several studies have reported that UV radiation reduces survival of fish larvae. However, indirect ... -
Effects of Fishing Tourism in a Coastal Municipality: a Case Study from Risør, Norway
(Journal article; Peer reviewed, 2011)Recreational fishing has become an important part of the Norwegian tourist industry. The coastal municipality of Risør, southern Norway, is considering further development of its marine fishing tourism to increase local ... -
Egg buoyancy variability in local populations of Atlantic cod (Gadus morhua)
(Journal article; Peer reviewed, 2012-06-29)Previous studies have found strong evidences for Atlantic cod (Gadus morhua) egg retention in fjords, which are caused by the combination of vertical salinity structure, estuarine circulation, and egg specific gravity, ... -
Egg distribution, bottom topography and small-scale cod population structure in a coastal marine system
(Journal article; Peer reviewed, 2007-03-12)Coastal marine species with pelagic egg and larval stages, such as the Atlantic cod Gadus morhua, can be structured into genetically distinct local populations on a surprisingly small geographic scale considering their ... -
