In Louisiana, 5/6 bowfin examined were parasitized by the tapeworm
Prorteocephalus ambloplitis, and 4/6 by Haplobothrium glubuliforme
(Sogandares-Bernal, 1955).
In South Carolina, 12/12 examined were parasitized by P.perplexus (a
parasite specializing on bowfin), 10/12 by H. globuliforme (Aho et al.,
1991). Average number of worms per bowfin were: P.perplexus - 44.9,
H.globuliforme - 2.0, and total worms - 114! Also, species richness of
bowfin helminths is quite high (6.5 species/bowfin) compared with other
freshwater fishes (usually < 2 species).
Both studies were of adult fish and neither addressed parasite-induced
mortality.
