This genus was revised by Kuperman (1973). It is
well characterized by the presence of four large,
trident-shaped hooks on the apical disc, an unsegment
strobila and a large, thick-walled cirrus sac.
Three species of the genus
Triaenophorus
are known
from Canadian fishes:
T. crassus
Forel,
T. nodulosus
( Pallas) and
T. stizostedionis
Miller. The three are
very similar anatomically. Species of
Triaenophorus
were first recorded from North American fish by
Cooper (1918), He recognized
T. crassus
(which he
referred to as
T. robustus
) from the intestine of
Esox
lucius
and the muscles of
Leucichthys artedi
and He
also found
T. nodulosus
in several species of fishes.
The type species
T. nodulosus
(Pallas, 1781) syns.
aenia rugosa
Pallas, 1760 in part;
Taenia piscium
Pallas, 1766 in part;
Taenia lucii
Müller, 1776 in part;
Taenia tricuspidatus
Bloch, 1779, Kuperman 1973).
And
T.crassus
Forel, 1868 (syn. T.
robustus
Olson,
1893), Two type of the parasite have been reported
from a number of second (fish) intermediate hosts in
Europe and Asia, including the former Soviet Union.
Triaenophorus nodulosus
also occurs in North
America are differ markedly from each other in the
morphology and size of the hooks and their larvae
(plerocercoids) infect different fish hosts (Lawler and
Scott 1954, Hoffman 1999).
This is the first recording presence of two species of
parasite, and are represented as a new locality
recorded of
Triaenophorus nodulosus
and
T. crassus
that isolated from the intestinal and musculse of the
Parasilurus triostegus
, and the
Parasilurus Triostegus
as a new host in the world.
