Última Population biology of <i>Anguillicola crassus</i> in the final host <i>Anguilla anguilla</i> OMA Thomas, K.; Ollevier, F.P.. Eels were sampled twice a month (March 1990 though March 1991) at the Kolenhaven (Albertcanal, Genk, Belgium) and examined for <i>Anguillicola crassus</i> nematodes in the swimbladder. Averaged over all samples, 90.2% of the 345 eels were infected with a mean intensity (averaged for all stages) of 17 nematodes. Thirty-one percent of all nematodes, which were adult worms or their remnants, were present in the swimbladder lumen, while the other 69% which consisted of the third or fourth larval stage and preadults were found in the swimbladder wall. No clear seasonal fluctuations in parasite prevalence or mean intensity were observed. Both L<sub>3</sub>-larvae and mature adult worms were present throughout the year. Eggs or...

Ano: 1992 URL: http://www.vliz.be/imisdocs/publications/299071.pdf The life cycle of <i>Anguillicola crassus</i> OMA De Charleroy, D.; Grisez, L.; Thomas, K.; Belpaire, C.; Ollevier, F.P.. For some years now the parasitic swim bladder nematode <i>Anguillicola crassus</i> of the European eel <i>Anguilla anguilla</i> L., has been reported from several European countries. The entire life history of this parasite has recently been elucidated in our laboratory. Young larvae leave the swim bladder of the host via the pneumatic duct and reach the water through the digestive tract. They are ingested by small copepods (Cyclopoida), which act as intermediate hosts. Larvae remain in the hemocoel until the copepods are eaten by the final host, the European eel. Larvae penetrate through the intestinal wall and reach the swim bladder where they develop into adults. When infected copepods are eaten by other small fish, such as carp...
