    In:  Supplement to: Berg, Florian; Slotte, Aril; Johannessen, Arne; Kvamme, Cecilie; Clausen, Lotte Worsøe; Nash, Richard DM (2017): Comparative biology and population mixing among local, coastal and offshore Atlantic herring (Clupea harengus) in the North Sea, Skagerrak, Kattegat and western Baltic. PLoS ONE, 12(10), e0187374, https://doi.org/10.1371/journal.pone.0187374

    Description: The complex population structure of Atlantic herring (Clupea harengus) was studied in the northeast Atlantic. Biological and environmental data from 1970-2015 of 13 local, coastal and oceanic areas of the North Sea, Skagerrak, Kattegat and western Baltic were analyzed. The aim was to identify distinct populations by comparing historical data on the temporal and spatial variation in phenotypic characteristics as well as to indicate mixing of populations in time and space. Our data indicated clear variation in biological characteristics such as mean vertebral counts (VS), growth and maturity ogives among herring caught in the defined areas. Generalized adaptive models demonstrated temporal, as well as intra-annual, dynamics of VS to be a population specific trait in this study. High variability of VS was observed and it was not affected by environmental factors. The variability can be explained by variation in presence/absence of herring populations in certain areas. The three main populations identified within this paper represented the three managed stocks in this area: Norwegian spring spawners (NSS), western Baltic spring spawners (WBSS) and North Sea autumn spawners (NSAS). In addition, several local populations have been identified in fjords or lakes along the coast. Our data could not demonstrate direct mixing of local populations with the three main populations. However, local populations are included in the management of the three stocks, without knowing the extent of mixing. Our results clearly highlighted the importance of recognizing and understanding herring dynamics and mixing of populations as this is a challenge for the management of herring.

    Description: The data submitted is used in a comparative analysis of the diet of one of the globally most numerous myctophids, the Glacier lantern fish Benthosema glaciale, across four deep basins of the North-Atlantic. B. glaciale is a small fish species that contribute to carbon flux to the deep basins of the open ocean, and is thus considered an important element of the biological carbon pump (BCP). Data submitted is length and weight of fish analyzed for stomach content. In addition there are available taxonomic information, weight and number of prey items of each fish that has stomach content, as long as it has been possible to assign prey to a species or other taxonomic category. Unidentified prey usually had a high degree of digestion and individual items could not be counted, but could be weighed. Sampling were undertaken onboard the RV G.O. Sars during a six week long transatlantic scientific survey from Bergen (Norway) to Nuuk (Greenland) and back to Bergen in May and June 2013. Samples of B. glaciale for stomach content analysis were collected from three Harstad trawl hauls and 16 Macroplankton trawl hauls. The Harstad trawl is a graded (variable mesh size), small mid-water trawl with 20 m vertical opening and 15 m wing spread (Godø et al., 1993). The Macroplankton trawl on the other hand is a light pelagic trawl that has a nominal 6x6 m trawl opening and mesh size of 3 mm square light opening (8 mm stretched, knot to knot) from the trawl mouth along the entire trawl length to the cod-end (Hassel et al., 2017; Klevjer et al., 2020).
