assertion that Atlantic herring is population rich, i.e. ‘‘composed of [a large number of] relatively discrete self-sustaining populations’’ (Sinclair and Iles, ). However, since early on in the development of herring population structure theory, many authors have cited evidence that is . The herring resource was previously divided into the Georges Bank and Gulf of Maine stocks, based not on genetic but morphometric differences (Overholtz, ) and the Georges Bank/Nantucket Shoals and coastal Gulf of Maine herring have been identified as two distinct spawning components with many smaller units embeeded within those (Vonderweidt et al., ).
Morphometric analysis and tagging studies suggest that spawning populations may be distinct, but mitochondrial genetic analyses did not find distinct subpopulations. To help resolve this, I conducted a finer scale genetic study of the Atlantic herring in the Gulf of Maine using short tandem repeat genetic markers (microsatellites). Using information for nine microsatellite loci in a total of fish, we analyzed genetic differentiation among Atlantic herring from eleven spawning locations distributed along a longitudinal gradient from the North Sea to the Western Baltic. Overall genetic differentiation was low (θ = .

In morphometric analyses, allometric growth, i.e. heterogeneity in body size among samples, can result in heterogeneity of shape without providing information on differences in body proportions among populations (Reist, ). In the present study, there were significant correlations with body length for morphometric and meristic characters.

Lack of biochemical genetic and morphometric evidence for discrete stocks of Northwest Atlantic herring Clupea harengus harengus Historically, herringstock delinea tion has been based on spawning site because herring are presumed to return to their natal beds to spawn (Sindermann ). Forex ample, WheelerandWinters().
The Atlantic herring (Clupea harengus) is a model system for ecological adaptation and the consequences of natural selection (Martinez Barrio et al. ; Lamichhaney et al. ; Hill et al. ), largely due to the enormous population size minimizing genetic Atlantic herring is, in fact, one of the most abundant vertebrates on Earth, with schools comprising more than a billion Cited by: 9.
Jonathan A. Hare, David E. Richardson, in Stock Identification Methods (Second Edition), Atlantic Herring (Clupea harengus) in the Northwest Atlantic OceanAtlantic herring has long been a focal species of ichthyoplankton monitoring programs on both sides of the North Atlantic.
The resulting ichthyoplankton data have been used in stock identification, as an indicator of spawning. Genetic methods such as protein electrophoresis and variation in structure of nucleic acids were widely applied to herring from the Atlantic and Pacific (Anderson et al., ;Kornfield et al.

Two opposing concepts of Atlantic herring, Clupea harengus L., population structure are critically reviewed with the objective of unifying these divergent views under the metapopulation concept.
It is concluded that neither the discrete population concept nor the dynamic balance concept adequately explains all the data associated with herring population structure and dynamics, including.
Three samplings of sea herring and one sampling of lake herring were studied. The genetic analysis showed a significant (P herring samplings and no. The esterase enzymes of the tissues of Atlantic herring (Clupea harengus harengus) were analyzed by starch gel electrophoresis.
Four sets of esterase bands were distinguished by their electrophoretic mobility, their relative activity with the two substrates, alpha‐naphthyl acetate and alpha‐naphthyl butyrate, and their relative concentrations in plasma, liver, and heart tissues. We conducted an analysis to determine if Pacific herring (Clupea harengus pallasi) stocks occurring in different localities in British Columbia waters could be separated using morphometric and meristic minant function analysis was applied to morphometric and meristic characters taken from food herring samples.
Identification of genetic changes that allow a species to adapt to different environmental conditions is an important topic in evolutionary biology. In this study we analyzed whole-genome resequencing data of Atlantic herring populations from both sides of the Atlantic Ocean and identified a number of loci that show consistent associations with spawning time (spring or autumn).
Images for morphometric analyses were taken using a Nikon Coolpix S camera mounted on a frame 50 cm above the processing table. Each fish was placed underneath the camera on a plastic grid. Fifteen landmarks were used on each fish, and 10 of the landmarks were marked by pins prior to photo documentation (Armstrong and Cadrin ).
The Atlantic herring (Clupea harengus), one of the most abundant marine fishes in the world, has historically been a critical food source in Northern Europe. It is one of the few marine species that can reproduce throughout the brackish salinity gradient of the Baltic Sea.
Previous studies based on few genetic markers have revealed a conspicuous lack of genetic differentiation between.

Atlantic herring are one of nearly herring species in the family Clupeidae. They grow quickly, up to 14 inches. They can live up to 15 years. They are able to reproduce when they reach age 4. Atlantic herring migrate in schools to areas where they feed, spawn, and spend the winter.
Atlantic herring is an excellent species for studying the genetic basis of adaptation in geographically distant populations because of its characteristically large population sizes and low genetic drift. In this study we compared whole-genome resequencing data of Atlantic herring populations from both sides of the Atlantic Ocean.
Genetic and morphological structure of tub gurnard Chelidonichthys lucerna populations in Turkish marine waters were investigated with mtDNA sequencing of 16S rRNA and morphological characters.C. lucerna samples were collected from the Black Sea, Marmara, Aegean and northeastern Mediterranean coasts of Turkey.
The lowest genetic diversity was found in the northeastern. Gillnet sampling and analyses of otolith shape, vertebral count and growth indicated the presence of three putative Atlantic herring (Clupea harengus L.) populations mixing together over the spawning season February–June inside and outside an inland brackish water lake (Landvikvannet) in southern spawning of oceanic Norwegian spring spawners and coastal Skagerrak spring.

Previous studies based on few genetic markers have revealed a conspicuous lack of genetic differentiation between. The Atlantic herring is one of the most common fish in the world and has been a crucial food resource in northern Europe.
One school of herring may comprise billions of fish, but previous studies had only revealed very few genetic differences in herring from different geographic regions. This was unexpected since Atlantic herring is one of the few marine species that can reproduce .
