Can the DAB (Limanda limanda) be a paratenic host of Anguillicola crassus (Nematoda; Dracunculoidea)? The Gulf of Gdańsk and Vistula Lagoon (Poland) example.
Anguillicola crassus is an Asian nematode, dwelling in eel swim bladder and accidentally introduced to Europe. The eel becomes infected by consuming either crustaceans (intermediate hosts) or small fish (paratenic hosts), supporting stage 3 larvae. In 2002, 15 specimens of dab (Limanda limanda) caught in the Gulf of Gdarisk and 8 caught in the Vistula Lagoon were examined for the presence ofA. crassus larvae. Two Gulf of Gdatisk specimens and one Vistula Lagoon fish were found to host 4 stage 3 larvae of A. crassus. This is the first world's record of A. crassus in the dab. It is suggested that, due to a large size of the infected fish, they cannot function as paratenic hosts in the A. crassus life cycle.
