Anguillicoloides crassus. In: Fish parasites. Pathobiology and protection. WOO P.T.K. & BUCHMANN K.
The nematode Anguillicoloides crassus has spread across four continents in just a few decades, and now infects at least six eel species. Anguillicolosis causes severe pathology in the hosts'swimbladder, including lesions, inflammation, haemorrhaging and fibrosis. Losses have been reported in both wild and farmed eels. Concerns have also arisen over the capability of affected silver eels (i.e. mature individuals) to complete their deep-sea reproductive migration upon which all restocking and cultivation activities exclusively rely.
Anguillicolosis is now listed among the main potential threats to the eel fishing industry and to the survival of both the European and the American eel species.
