BIOGEOGRAPHICAL RELATIONSHIPS OF THE EEL PARASITE ANGUILLICOLA CRASSUS REVEALED BY RANDOM AMPLIFIED POLYMORPHIC DNA MARKERS (RAPDS)
The introduction and the rapid expansion of the nematode Anguillicola crassus in Europe in the early 80’s is one of the causes of the decrease of the European eel, Anguilla anguilla, populations. The aims of this work were to study, using RAPD markers, the genetic diversity and the population relati...
