Lernaeenicus vorax Richiardi, 1877 copepode parasite de sciaenides du golfe de Tunis [Tunisie]

ABSTRACT

The study of the Tunis bay Sciaenidae has made it possible to point out the presence of a parasite Copepod Lernaeenicus vorax Richiardi, 1877 with a more important parasitism in Argyrosomus regius [11.5%] and Umbrina cirrosa [9.2%] in Sciaena umbra [0.6%]. The parasites, chiefly, one per host, get fixed on the right side or on the left one preferably at the level of the fish's fins. Among Umbrina cirrosa the juveniles ones have proved to be more parasitic [82.13%] than the adults ones [17.85%]
