✦ Synopsis

Anguillicola was not reported in Denmark until 1986, but has most likely been present before. 17 places have been sampled in Jutland and on Zealand. In 6 places Anguillicola was present, 4 in Jutland and 2 on Zealand.

The Anguillicola has probably been introduced in one place (the Ringkabing Fjord) by trade with the Netherlands. There is every probability that eels from the samples south and north of the Ringkabing Fjord would be infected, if the spreading of the Anguillicola had taken place by natural migration. As this was not the case we may conclude that the Anguillicola was spread by man. Inside Denmark the infection is also spread by man and can in almost all of the Anguillicola infected waters be tracked to the Ringkabing Fjord.

Comparison of the condition factors w/e3 -1000 did not show significant differences between infected and non infected eels.
