Anmärkningar | Visual size-selective plankton feeder (Ref. 89567) Has the ability to switch between particulate- and filter-feeding (Ref. 4809). Adult feed on planktonic crustaceans, mollusc larvae, arrow worms, ctenophores, small fish (incl. eggs and larvae) (Ref. 188). Preyed upon by fish, birds, and marine mammals (Ref. 89563). Parasites found are protozoans, myxosporidians, trematodes, cestodes, nematodes and copepods (Refs. 5951, 37032). Herring biomass has shown inverse correlation with the biomass of sprat, a competitor for planktonic food (Refs. 82765; 82766). Benthopelagic and oceanodromous. Schooling species. Moves vertically in the water column, surfacing at dusk and descending at dawn. Biological anti-freeze enables tolerance to below zero temperatures up to -2.2°C. Found on the Scotian shelf at temperatures of 0°C-11°C. Filter feeds at low light with small prey, and feeds on larval fish, planktonic crustaceans, and molluscs at better lighting conditions (Ref. 117245). |
