The white-beaked dolphin Lagenorhynchus albirostris is the most numerous cetacean after the harbour porpoise Phocoena phocoena in the North Sea, including Dutch coastal waters. In this study, the diet of 45 white-beaked dolphins stranded on the Dutch coast between 1968 and 2005 was determined by analysis of stomach contents. Although 25 fish species were identified, the diet was dominated by Gadidae (98.0% by weight, 40.0% in numbers), found in all stomachs. All other prey species combined… 
Pathological Findings in White-Beaked Dolphins (Lagenorhynchus albirostris) and Atlantic White-Sided Dolphins (Lagenorhynchus acutus) From the South-Eastern North Sea
The most common post-mortem findings were emaciation, gastritis and pneumonia, which was most likely caused by bacterial infections, in white-beaked dolphins stranded along the southeastern North Sea between 1990 and 2019.
White-beaked dolphin distribution and association with prey in the Barents Sea
No strong dolphin responses to capelin collapse and recovery were observed, indicating sufficient availability of alternative prey during the collapse, and the poor dolphin–prey associations in this area could indicate dolphin distributions spatially constrained by physiological limitations, habitat productivity, or niche partitioning.
Color patterns in white‐beaked dolphins (Lagenorhynchus albirostris) from Iceland
Few studies have examined the natural complex pigmentation patterns of white-beaked dolphins. From 2002 to 2014, whale-watching trips in Iceland provided a platform of opportunity to collect a large
Diet Analysis of Stranded Bottlenose Dolphins ( Tursiops truncatus ) in Virginia
The data presented in this study promise to enhance policy and management by establishing baseline information on natural history as well as a quantitatively assessed indicator for peracute underwater entrapment that can be referenced to study local shifts in natural history or incidence of bycatch.
Lagenorhynchus albirostris (Cetacea: Delphinidae)
A robustly built dolphin with black, white, and gray coloration, L. albirostris has a whitish beak, a prominent dorsal fin, and a white saddle behind the fin.
PFAS profiles in three North Sea top predators: metabolic differences among species?
Carnivora species including Pinnipedia have a much higher capacity of transforming PFOSA to perfluorooctane sulfonic acid (PFOS) than cetacean species, indicating that PFAS contamination in marine mammals is investigated more closely than previously thought.
Marine mammal consumption and fisheries removals in the Nordic and Barents Seas
In this study, we assess prey consumption by the marine mammal community in the northeast Atlantic [including 21 taxa, across three regions: (I) the Icelandic shelf, Denmark Strait, and Iceland Sea
Microalgae diets for landbased aquaculture of the cockle Cerastoderma edule: impacts of dietary fatty acids on growth
This thesis focused on the dietary fatty acids impact on growth, survival and fatty acid composition of juveniles of the common cockle Cerastoderma edule, for land-based culture and indicated that EPA is necessary for the short-term growth of cockles.


Seasonal distribution of white-beaked dolphins (Lagenorhynchus albirostris) in UK waters with new information on diet and habitat use
Details of the seasonal and geographical distribution of white-beaked dolphins around the UK are presented, along with new information on their diet and habitat use, and analysis of historical stranding records shows a segregation of the sexes.
White-beaked Dolphin: Lagenorhynchus albirostris
On three specimens of Lagenorhynchus albirostris Gray, 1846 (Mammalia, Cetacea)
Recently the Zoological Museum in Amsterdam came into possession of three specimens of the White-beaked Dolphin, Lagenorhynchus albirostris. As data on this species are rather scarce, it may be
Comparing the diet of cod (Gadus morhua) and grey seals (Halichoerus grypus): an investigation of secondary ingestion

Overlaps between the size distributions of prey species/groups suggest that secondary ingestion was possible and should be considered in future seal diet studies.
Stomach contents of English Channel cetaceans stranded on the coast of Normandy
During 1998–2003 stomach contents of 47 marine mammals stranded on the coast of Normandy were analysed, finding that common dolphins ate mainly gadoid fish, gobies and mackerel and cephalopod beaks were scarce.
Cetaceans stranded in the Netherlands from 1998 to 2007
Between 1998 and 2007, 2063 cetaceans were found stranded in the Netherlands, representing at least 14 species, and it is estimated that along the North Sea coast at least 19% more porpoises were washed ashore than were actually recorded.
The Smaller Cetacea of Eastern Canadian Waters
An account is given of the known records, distribution and migrations of the smaller Odontocete whales occurring in eastern Canadian waters, with measurements of specimens obtained of the rarer
Abundance of harbour porpoise and other cetaceans in the North Sea and adjacent waters
1. The status of small cetaceans in the North Sea and adjacent waters has been of concern for many years. Shipboard and aerial line transect surveys were conducted to provide accurate and precise
Assessing the use of hard parts in faeces to identify harbour seal prey: results of captive-feeding trials
Faeces were collected from four captive harbour seals that consumed known amounts of herring, walleye pollock, Pacific hake, surf smelt, and juvenile chinook salmon to determine which structures passed through the digestive tract and which of these could be used to determine the type and number of fish consumed.
A measure of the variability of hard part recovery among sea lions showed no difference for certain herring, pollock, and squid structures, however, there was a significant difference for salmon and Atka mackerel structures.
