latitudinal gradient in otolith shape among local populations of atlantic herring Clupea harengus l in norway
PLOS ONE, 2015Co-Authors: Lisa Anne Libungan, Aril Slotte, Ase Husebo, Jane Aanestad Godiksen, Snæbjörn PálssonAbstract:Otolith shape analysis of Atlantic herring (Clupea harengus) in Norwegian waters shows significant differentiation among fjords and a latitudinal gradient along the coast where neighbouring populations are more similar to each other than to those sampled at larger distances. The otolith shape was obtained using quantitative shape analysis, the outlines were transformed with Wavelet and analysed with multivariate methods. The observed morphological differences are likely to reflect environmental differences but indicate low dispersal among the local herring populations. Otolith shape variation suggests also limited exchange between the local populations and their oceanic counterparts, which could be due to differences in spawning behaviour. Herring from the most northerly location (69°N) in Balsfjord, which is genetically more similar to Pacific herring (Clupea pallasii), differed in otolith shape from all the other populations. Our results suggest that the semi-enclosed systems, where the local populations live and breed, are efficient barriers for dispersal. Otolith shape can thus serve as a marker to identify the origin of herring along the coast of Norway.

stock structure of atlantic herring Clupea harengus in the norwegian sea and adjacent waters
Marine Ecology Progress Series, 2015Co-Authors: Christophe Pampoulie, Lisa Anne Libungan, Sarah J Helyar, Gudbjorg Olafsdottird, Jan Arge Jacobsen, Sigurlaug Skirnisdottir, Aril Slotte, Guðmundur J. Óskarsson, Ásbjörn Jónsson, Horaldur JoensenAbstract:Table S1. Characteristics of multiplexes for 24 microsatellite loci of Atlantic herring Clupea harengus. Tm stands for annealing temperature and l for micro-litres of primer used. Genotyping quality reports the percentage of individuals which were correctly genotyped at a specific microsatellite locus. The forward primers were labelled with dye colors: 6-FAM (blue dye), NED (yellow dye), PET (red dye) and VIC (green dye).

Physico-chemical and functional properties of roe from autumn spawning herring (Clupea harengus harengus L.)
Food Research International, 1994Co-Authors: N. Gagné, L.t. AdambounouAbstract:Abstract Various functional properties (viscosity, pH, emulsifying capacity, and emulsion stability) of roe from autumn spawning herring ( Clupea harengus harengus L.) were evaluated in relation to their stage of maturity (three stages of maturity). Analysis of variance indicated that maturity stage did not significantly affect ( P >0·05) the various functional properties examined.

Pearson, R A Elston, R W Bienert, A S Drum, L D AntrimAbstract:Following record harvests of Pacific herring (Clupea pallasi) in Prince William Sound, Alaska, in the 3 years after the Exxon Valdez oil spill, the fishery failed in 1993.
