“…Minke whales of the Northeast Atlantic represent one of the most euryphagous stocks of baleen whales (Haug et al 1995a, Haug et al 1996a, but the bulk of their diet is comprised of relatively few species. Krill and herring, the two most prominent prey items in the diet, were consumed in approx imate ly equal amounts.…”

Although pil ot studies to examine diet were also carried out (Nord0y and Blix 1992), dietary compositi on was not studied in detail until [1992][1993][1994], when the stomach contents of 223 minke whales were analysed, and prey availability was estimated simultaneously (Haug et al 1995a, Haug et al 1995b, Haug et al 1996a, Haug et al 1997a (Fig. 1).…”

“…1987). The diet has been shown to vary between geographical areas, and with different seasons of the year (Haug et al 1995a, Haug et al 1995b, Haug et al 1996a). There are also substantial seasonal vari ations in the energy densities of many of the prey items (Martensson et al 1996).…”

Data on energy requirements, diet composition, and stock size were combined to estimate the consumption of various prey species by minke whales (Balaenoptera aeutorostrata) in Northeast Atlantic waters. In the period 1992-1995, the stock of 85,000 minke whales appeared to have consumed more than 1.8 million tonnes of prey per year in coastal waters off northern Norway, in the Barents Sea and around Spitsbergen during an assumed 6 month stay between mid-April and mid-October. Uncertainties in stock estimates suggest a 95% confidence range of 1.4 -2

Recent responses to changes in stocks of prey species by seabirds breeding in the southern Barents Sea

Seabirds breeding in the southern Barents Sea feed mainly on pelagic fishes -capelin Mallotus villosus, herring Clupea harengus, sand eels Ammodytes sp., and polar cod Boreogadus saida. This study shows how seabirds breeding in two colonies, one in northern Norway and one off the Kola Peninsula, Russia have responded to the recent huge changes in the capelin and herring stocks through changes in chick diet and breeding success. It seems that after recent collapses in the capelin stocks, the surface-feeding kittiwakes Rissa tridactyla are now having difficulty in finding enough food to maintain high breeding success and a positive population trend. While the pursuit diving common guillemots Uria aalge and puffins Fratercula arctica are faring better, there are signs that they too are having more difficulty in finding sufficient food despite the return of I-group herring to their foraging areas.
