[The fertility of thorny-headed worms in the genus Echinorhynchus (Acanthocephala: Echinorhynchidae) from Lake Baikal].
The total number of eggs (absolute fecundity) and the number of eggs per 1 gr of body weight (relative fecundity) of Echinorhynchus borealis Linstow, 1901, E. salmonis salmonis Muller, 1784, E. s. baicalensis Bogolepova, 1957 and E. truttae Schrank, 1788 from the Baikal lake was examinide. The absolute fecundity decreases in the row or species: E. borealis (26,200 eggs), E. s. salmonis (110,113), E. truttae (8123), E. s. baicalensis (6087). The fecundity of acanthocephalans depends on the host species. The dependence of the whole number of larvae upon the body length of females (r = 0.804) is shown.
