A unifying theory explaining different power budget formulations used in modern scientific echosounders for fish abundance estimation
(Fisken og Havet;7-2014, Research report, 2014-12-31)Acoustic methods used in fish abundance estimation constitute a key part of the analytic assessment that makes the basis for fisheries research and international regulations of marine resources. The methods rely on ... -

Acoustic investigations of size and distribution of the Barents Sea capelin stock 1972-1997
(Fisken og havet, Research report, 1998)The abundance and geographical distribution of the Barents Sea capelin stock have been monitored using acoustic methods since 1972. Today, 26 years later, it is one of the few stocks, within the ICES area, for which an ... -
Advection schemes for coastal ocean models on unstructured triangular meshes
(Fisken og havet, Research report, 2000)A variety of advection schemes suitable for use on unstructured triangular grids have been investigated for possible use in coastal ocean models based on the results of a literature survey. Idealised test cases were ... -
Aggresive behavior of two size classes of four salmonid species
(Fisken og havet, Research report, 1995)Groups of eight parr of hatchery reared Atlantic salmon (Salmo salar), sea trout (Salmo trutta), rainbow trout (Oncorhynchus mykiss) and Arctic charr (Salvelinus alpinus) were investigated in monoculture with two size ... -
Aggressive behaviour of four salmonid species in duoculture
(Fisken og havet, Research report, 1995)Aggressive behaviour of groups of eight parr in different species combinations was studied to investigate the potential of duoculture in rearing of salmonids. The species used were Atlantic salmon (Salmo salar L.), sea ... -
Akkar (Todarodes sagittatus (Lamarc)) Innsig og forekomst ved norskekysten og tilstøtende havområder høsten 1979 - våren 1980
(Fisken og havet, Research report, 1980)During the second half of 1979 T. sagittatus invaded the eastern Norwegian Sea, the northern North Sea and the coastal and bank areas of the Faroes, Iceland and Norway. The squid stayed in parts of the areas at least ... -
Akkar (Todarodes sagittatus (Lamarck)). Norske undesøkelser i april-desember 1980.
(Fisken og havet, Research report, 1981)During the second half of 1980 T. sagittatus invaded the northeastern Norwegian Sea and adjacent coastal areas in great abundance. The invasion coincided with the occurrence of large quantities of salps. Squid still ... -

Akustisk mengdemåling av bunnfisk på Mørekysten i mars 1980
(Fisken og havet, Research report, 1981)At the Møre coast there are important spawning areas for cod, coalfish, haddock and herring. As a part of an interaction study of these species, i.e. the predation of the demersal species on the spawning stock and the ... -
Akustisk mengdemåling av oppdrettslaks
(Fisken og havet, Research report, 1995)Continuous monitoring of the biomass in salmon cages is likely to increase the production efficiency. It would optimize density-dependent farm procedures, e.g food and drug administration, and provide a possibility for ... -
Akustisk mengdemåling av torsk og hyse i Barentshavet i februar 1976
(Fisken og havet, Research report, 1977)From l to 20 February observations of cod and haddock were carried out by R.V. "G.O. Sars" in the centra1 and eastern part of the Barents Sea. The survey was part of a program with the aim of estimating the abundance of ... -

AkvaVis - dynamisk GIS-verktøy for lokalisering av oppdrettsanlegg for nye oppdrettsarter : miljøkrav for nye oppdrettsarter og laks
(Fisken og havet, Research report, 2008)AkvaVis is a dynamic GIS tool for siting fish farms, and this report describes a prototype version for mussel farms. AkvaVis combines mappable characteristics such as depth, currents and distance from other objects, and ... -
Alders-lengdeforhold for kysttorsk i fangster fra Mørekysten
(Fisken og havet, Research report, 1981)Data from cod taken by Danish seine and fish-pots off Sunnmøre and Nordmøre in the years 1969, 1979 and 1980 are analysed. Three groups of coastal cod living separately, was found at Sunnmøre: The first consisted of ... -
Algeovervåking i Norge 1993
