Note the following from http://www.afsifs.vt.edu/afspos.html
Diseases caused by bacteria, viruses, and parasites are all too often
conveyed along with introduced aquatic species (see Hoffman and
Schubert 1984; Shotts and
Gratzek 1984 for reviews). This aspect represents one of the most
severe threats that an introduced species may pose to a native
community. Transfer of diseased
fish was no doubt responsible for introduction of whirling~ disease
into North America from Europe. Recently, infectious hypodermal and
hematopoietic necrosis virus (IHHNV) has been spread to a number of
countries in conjunction with shipments of
live penaeid shrimp. IHHNV was first diagnosed in 1981 at shrimp
culture facilities in Hawaii among shrimp introduced from Panama
(Sindermann 1986). Even
"ich," one of the most common fish diseases worldwide, caused by a
ciliated protozoan, is thought to have been transferred from Asia
throughout the temperate zone
with shipments of fishes (Hoffman 1970, 1981).
