Projected habitat loss for Atlantic herring in the Baltic Sea
Marine Environmental Research, 2016Projected, climate-driven changes in rainfall patterns are expected to alter the salinity (S) of estuaries and larger brackish water bodies, such as the Baltic Sea. Some marine fish larvae are potentially more sensitive to low salinity than older stages, hence we compared the low salinity tolerance of Atlantic herring (Clupea harengus) larvae at the ...

Stock identification of Atlantic herring in the Northeast Atlantic based on otolith shape
2013No abstracts are to be cited without prior reference to the author. Otolith shape variation of seven herring stocks in the Northeast Atlantic and Canada was studied to see if otolith shape can be used to discriminate the stocks. The otolith shape was obtained using quantitative shape analysis, transformed with Wavelet and analysed with multivariate ...

Temperature and Neural Development of the Atlantic Herring (Clupea harengus L.)
Comparative Biochemistry and Physiology Part A: Physiology, 1997Embryos of Atlantic herring (Clupea harengus L.) from the Buchan (Northern North Sea) stock were incubated from fertilisation until hatching at temperatures of 5, 8, 12, and 15 degrees C. The relative timing of development of the Kolmer-Agduhr (KA) neurons, the posterior lateral line nerve, the motor neurons, and myotubes were determined with respect ...

Temperature And Myogenesis In Embryos Of The Atlantic Herring Clupea Harengus
Journal of Experimental Biology, 1995ABSTRACT The development of axial muscles has been investigated in spring-spawning Atlantic herring (Clupea harengus L.) reared at 5, 8, 12 and 15 °C. In 1994, around 90 % of embryos hatched after 28 days at 5 °C, 16 days at 8 °C, 9 days at 12 °C and 8 days at 15 °C.

INHERITANCE OF ALLOZYMES IN ATLANTIC HERRING (CLUPEA HARENGUS HARENGUS)
Canadian Journal of Genetics and Cytology, 1981Progeny from single pair crosses of Atlantic herring were examined to determine the heritability of genetic variation at seven polymorphic allozyme loci. Mendelian inheritance of codominant autosomal alleles was established for IDH-2, LDH-1, LDH-2, ME-2, PGM-1, and PGI-2.

Monitoring and Management of the Northeast Atlantic Herring Stocks
Canadian Journal of Fisheries and Aquatic Sciences, 1985The collapse of all the major herring stocks in the Northeast Atlantic in the late 1960s and the early 1970s was undoubtedly the most striking phenomenon in the history of the European fisheries. The events leading to the collapse show similar features for all the herring stocks: a sharp increase in catches over a few years, followed by a rapid ...

Management of Sea Herring Fisheries in the Northwest Atlantic
Journal of the Fisheries Research Board of Canada, 1973Regulatory measures for herring set by the International Commission for the Northwest Atlantic Fisheries (ICNAF) represent an important milestone in international fishery regulation because for the first time, they provide for national quotas in addition to a total catch limitation.The first regulatory measures were proposed in January 1972 to be ...

Atlantic herring operational assessment report 2015
2015The Atlantic herring stock was last assessed as a benchmark during the 54th Stock Assessment Workshop using data through 2011 (NEFSC 2012). Data were updated through 2014 for this operational assessment. The methods of data processing and the stock assessment model configuration were the same as those accepted at the previous benchmark (NEFSC 2012 ...

Biochemical Population Genetics of Atlantic Herring, Clupea harengus
Copeia, 1984for the gene products of 40 protein-coding loci using starch gel electrophoresis. A nested contingency-table analysis, a cluster analysis of genetic distances between populations and a gene-diversity analysis of allele-frequency data each showed that there was little genetic differentiation among North American populations and among European ...
