Contents of several inorganic substances in European eel infected and uninfected by Anguillicola crassus (Nematoda)

摘要

ABSTRACT: The content of 5 macroelements and 5 microelements were analyzed using the atomic absorption method in muscle samples of European eels infected and uninfected by Anguillicola crassus. The mean contents of these substances in infected eels were statistically highly significantly lower in Ca, P, Fe, Mn, but only statistically significantly lower in Na, Mg, Zn and Cu as compared to uninfected fishes. These differences are discussed in relation to hematophagus feeding and pathogenity of the parasite.>
