Between the,ears 1990 and 2000, an attempt was made to determine the causes of death of 55 harbour porpoises stranded along the Belgian and northern French coasts. From 1990 to 1996, only five carcasses were collected as against seven in 1997, eight in 1998, 27 in 1999 and eight in 2000. The sex ratio was normal and most of the animals were juvenile. The most common findings were emaciation, severe parasitosis and pneumonia. A few cases of fishing net entanglement were observed. The main microscopical lesions were acute pneumonia, massive lung oedema, enteritis, hepatitis and gastritis. Encephalitis was observed in six cases. No evidence of morbillivirus infection was detected. Pneumonia was associated with bacteria or parasites, or both. The causes of death and the lesions were similar to those previously reported in other countries bordering the North Sea. The cause of the increased numbers of carcasses in 1999 was unclear but did not include viral epizootics or net entanglement. A temporary increase in the porpoise populatiou in the southern North Sea may have been responsible. (C) 2002 Elsevier Science Ltd. All rights reserved. [less ▲]

Pathological investigations were carried out on 67 guillemots (Uria aalge) washed up on the Belgian coast between November 1993 and March 1994. Emaciation and acute haemorrhagic gastroenteropathy were observed in more than 70 per cent of the birds. There was no statistical relationship between the level of oil contamination and the severity of the lesions. Differences in bodyweight were accounted for by age, sex, emaciation, and acute haemorrhagic gastroenteropathy. The birds had a severe weight deficit but the concentrations of pollutants were below acutely toxic levels. [less ▲]

During winter 1994-95, four and three sperm whales (Physeter macrocephalus) were stranded along the Belgian and the Dutch coasts, respectively. Necropsies and tissue samplings were collected 24 hrs post mortem. Lesions on several whales included round and linear skin scars, ventral skin abrasions, acute skin ulcers, acute ulcerative stomatitides, acute to chronic external otitides, and passive visceral congestion. In addition, these sperm whales appeared to be debilitated with severe weight deficit, had blubber thickness reduction, the absence of abdominal fat, and the intestinal tracts were almost empty. Three categories of lesions and their possible relation with the stranding were evaluated. Cutaneous scars observed on the seven whales appeared to have no relation with the stranding. The poor body condition and acute integument ulcerative lesions were present before the stranding. Ventral skin abrasions and visceral passive congestion were caused by the strandings. Absence of food in the alimentary tracts, evidence of weight loss and blubber thickness reduction were compatible with an extended presence of the sperm whales in the North Sea, where adequate food is not available. This might lead to progressive weakness, predisposing the animals to secondary pathogens such as viral diseases. Finally, the coastal configuration of the southern North Sea makes it a trap for sperm whales which have entered the area during their wanderings. [less ▲]

From 1992 to 1995, dead seabirds found on Belgian beaches were collected and various tissues of 241 birds were sampled for histopathological, bacteriological, parasitological, and toxicological investigations. The most common species examined was the guillemot (Uria aalge). Necropsies revealed cachexia (severe emaciation), acute haemorrhagic gastro-enteropathy and oil contamination in many of these birds. Statistical analyses were performed in order to explore correlations of these with biological parameters such as age, sex, and origin (pelagic or non-pelagic). The pelagic origin of seabirds were associated with the three main findings. Oil contamination was associated with acute gastro-enteropathy and cachexia, and cachexia was more prevalent among juveniles. Finally, cachexia and acute gastro-enteropathy were strongly associated. It is possible that oiled pelagic seabirds become cachectic and die of acute gastro-enteropathy. (C) 1997 International Council for the Exploration of the Sea. [less ▲]

Between February 1990 and July 1991, 18 harbour porpoises (Phocoena phocoena) and 248 common guillemots (Uria aalge), found dead along the Belgian and German coasts, were examined for their burden of helminths. A total of three species were found in the guillemots (one cestode, one nematode and one pentastomid), and six species in the porpoises (one trematode, one cestode and four nematodes). Among the guillemots the burden of helminths was not statistically different between juvenile and adult birds. The deaths of the birds were apparently not related to the parasite infections. In contrast, the adult porpoises were more heavily parasitised than the juveniles, except for one young porpoise stranded on the Belgian coast. In the porpoises, four species of parasites had a pathological effect and Torynurus convolutus was responsible for the death of one animal from the Belgian coast and three from the German coast.

During the 1992-1993 133 seabirds found on Belgian beaches were necropsied. Most frequent species were the guillemot (Uria aalge), the oystercatcher (Haematopus ostralegus), the kittiwake (Rissa tridactyla), the razorbill (Alca torda) and the herring gull (Larus argentatus). The three main observations were, in decreasing order, cachexia, acute and hemorrhagic gastroenteritis, and oil contamination of plumage and intestinal tract. The pelagic origin of seabirds was associated with all 3 observations; oil contamination was associated with acute gastro-enteritis and cachexia and, finally, the immature character was associated with cachexia. A hypothetical mechanism of death would be oiled pelagic seabirds that become cachectic and die of acute gastroenteritis. It is unlikely that seabirds act as a reservoir for bacteria, that were only occasionally identified in our material. Therefore, it appears that infectious agents play a minor role in seabirds stranding. [less ▲]
