New data on distribution of Norwegian (Atlantic) pollock Theragra finnmarchica (Gadidae) in the Barents Sea
Journal of Ichthyology, 2014Co-Authors: K. A. Zhukova, A.m. PrivalikhinAbstract:New data have been acquired on the biology, morphological features and distribution of Norwegian (Atlantic) pollock Theragra finnmarchica in the Barents Sea. Two individuals of this rare species gadoid (Gadidae) were caught in June and July 2012 in the south-eastern part of the Barents Sea, indicating a wider distribution area of this species than previously thought. It has been confirmed that a number of morphological features of Norwegian pollock is different from T. chalcogramma , and that it feeds on macroplankton (Euphausiidae, Hyperiidae).

on the finding of a rare species norwegian pollock theragra finnmarchica koefoed 1956 Gadidae in the barents sea
Journal of Ichthyology, 2010Co-Authors: A.m. Privalikhin, G. V. NorvilloAbstract:A description of a rare representative of the family Gadidae—the Norwegian pollock Theragra finnmarchica Koefoed, 1956—is given. The Norwegian pollock caught in November 2004 in the Barents Sea off Nadezhda Island is the first individual of this species officially recorded in Russia. At the present time, reliable information is available about 42 caught individuals of this species. A review was performed of evidence on the history of study and modern concepts of the origin, biology, and distribution of Norwegian pollock.

A mitogenomic approach to the taxonomy of pollocks: Theragra chalcogramma and T. finnmarchica represent one single species
BMC Evolutionary Biology, 2007Co-Authors: Anita Ursvik, Jørgen S. Christiansen, S-e. Fevolden, Ragna Breines, Dag H. Coucheron, Steinar JohansenAbstract:Background The walleye pollock (Theragra chalcogramma) and Norwegian pollock (T. finnmarchica) are confined to the North Pacific and North Atlantic Oceans, respectively, and considered as distinct species within the family Gadidae. We have determined the complete mtDNA nucleotide sequence of two specimens of Norwegian pollock and compared the sequences to that of 10 specimens of walleye pollock representing stocks from the Sea of Japan and the Bering Sea, 2 specimens of Atlantic cod (Gadus morhua), and 2 specimens of haddock (Melanogrammus aeglefinus).

the occurrence of theragra finnmarchicakoefoed 1956 teleostei Gadidae 1932 2004
Journal of Fish Biology, 2005Co-Authors: Jørgen S. Christiansen, S-e. Fevolden, Ingvar ByrkjedalAbstract:Ten specimens of the codfish Theragra finnmarchica (Teleostei, Gadidae) were known to science until 2003. Collections of 31 additional specimens made off north Norway between February 2003 and April 2004 provide information on the geographical and vertical distribution of this assumed rare species.

The polar cod of Porsangerfjorden, Norway; revisited
Sarsia, 2000Co-Authors: Jørgen S. Christiansen, S-e. FevoldenAbstract:Abstract The polar cod, Boreogadus saida (Lepechin, 1774) (Gadidae), is a genuinely arctic fish species, which was recorded from Norwegian waters, i.e. the Austerbotn Basin of Porsangerfjorden, for the first time in 1967. Whether the polar cod in Austerbotn are strays from arctic waters or represent a population of its own is a matter of debate. Here we review the scarce information available and provide circumstantial hydrological and biological evidence for a remnant population of polar cod that might have been isolated in Austerbotn since the late Weichselian glaciation (approximately 10 000 years BP) or, at least, since the ice winter 1902–03.

sex specific somatic otolith growth relationship in two Gadidae
Journal of Fish Biology, 2008Co-Authors: Maria Vallisneri, V. Trotta, S. Cavicchi, Corrado PiccinettiAbstract:Otolith and somatic mass of two Gadidae (Merlangius merlangus and Trisopterus minutus) were compared in order to analyse the sex-specific relationship between otolith and somatic growth at age. In the present study, otolith mass appeared a reliable indicator of age in both species. Otolith growth reflected somatic growth, but the relationship between these characters varied and differed between species and sexes.
