V. Barus et M. Prokes, FIRST RECORD OF THE LIGULA-INTESTINALIS PLEROCERCOID IN THE INTERGENERIC HYBRID OF CYPRINID FISHES (PISCES), Helminthologia, 32(1-2), 1995, pp. 49-51
The infection by Ligula intestinalis plerocercoids in two intergeneric
hybrids Blicca bjoerkna x Rutilus rutilus is described. The plerocerc
oids were found in adult fishes being fully infective as related to th
e lenghts and weights of these parasites. The parasite index (P. I.) h
