Zoologist Studies
Local Paddlefisli
. . . May Have Rare
Electrical Equipment
A renowned authority from
Cambridge University has
come to Nebraska to have
look at the snout-nosed Mis
souri river paddlefish.
The authority, Dr. Hans W
W. Lissmann, zoologist, chose
Nebraska as the result of cor
respondence with University
Professor Thomas B. Thor
son, a zoologist whose pisca
tonal interests run more to
sharks than to paddlefligh.
' Lissmann Is investigating
the paddlefish because it just
might be one of the relatively
few creatures which have
rare electrical equipment.
Lissmann and a lot of oth
er scientists can prove that
many fishes, including cat
fish, transmit electric
charges, some of which are
known to be put to practical
use.
Take, for instance, Profes
sor Lissmann's Gymnarchus
Niloticus you have to take it
scientific title and all because
nobody has ever given it a
common name. A liberal
translation, however, is that

it is a naked-tailed fish found
originally in the River Nile.
Gymnarchus transmits from
its tail and receives in its
head a constant stream of
tiny electric charges and in
the process establishes about
itself an electrical field, or
pattern, very useful in survi
val. When Gymnarchus gets
close to materials which in
terfere with his normal elec
trical pattern, he gets the
message and acts according
ly, maybe going on with his
business or leaving.
Use of the electrical sys
tem enables Gymnarchus to
go out to eat at night in com
parative safety. In darkness
most aquatic predators are
;nactive because they can t
see. Gymnarchus can't see
much either but rith his elec
trical apparatus operating he
doesn't need to. During the
day he rests in places the
predators can t reach.
In a sense, the Gymarchus
electrical system is better
than radar which relies on the
reflected "bounce" of an elec
tric signal. Gymnarchus
doesn't have to fool around
with bounces; he gets the
message direct when his pat
tern is distrubed.
Lissmann is the scientist
who first proved the abilities
of the Gymnarchus bv a se
ries of laboratory experiments
With a specimen he has kept
in a tank for more than 13
years.
The scientist says he is
now certain that some other
fishes and perhaps some am
phibians make use of built-
n equipment similar to that
owned by Gymnarchus.
The paddlefish, because it
has certain physical charac
teristics common to some of
the electrical specialists found
n Africa and South America,
aroused his interest and
that's why he came to Ne
braska. Paddlefish are be
lieved to be found mainly in
the Mississippi and Missouri
rivers and not in very many
other places.
After inspecting the brain
mechanism of a preserved
paddlefish In the University''
zoological laboratory, Liss-
mana and Thorson went to
the Gretna fish hatchery
where Superintendent Ger
hard Lenz provided a live
paddlefish for inspection and
"real life" electrical tests.
The game commission habit
ually displays a pair of pad
dlefish at the state fair.
Lissmann's interest in elec
tric fishes began years ago
when he wondered why some
few kinds of fishes swim in
a rigid position without swish
ing their tails.
He has found out why
Gymnarchus swims that way:
his rigid, torpedo-like position
is necessary for the effective
operation of his electrical
equipment.
What did Lissmann find
out about the paddlefish? lie
said, "I got all I came for
and more, really." But furth
er laboratory studies are nec
essary before any conclusions
can be reached.
