Anguillicola crassus was introduced into Dutch eelfarms by infected stocking material originating from inland fisheries. Within farms, suitable intermediate hosts for transmission of the parasite are available and uninfected stock becomes rapidly infected. In farming situations, only very heavy infections with the parasite can cause significant damage to fish, mainly by secondary infections. Treatment of fish infected with A. crassus is possible with L-Levamisole as a bath treatment or mixed with the feed, which results in complete immobilisation of the nematode. Transmission of the infection within farms can be controlled by keeping populations of copepods low. This can be accomplished by avoiding accumulations of organic matter within systems and/or control with chemical means. It can be stated that Anguillicola crassus does not pose the threat to intensive eel culture it once seemed to be.
