of species have been introduced into only a few countries. Eighty-six percent
of the species introduced have been recorded from 10 countries or less. This graph is read for example the first
column means that 29 countries have only had 1 species introduced, 6
countries have had only 2 species introduced and so on. I am concerned with the farthest bar to the
right that says 1 country has had 70 foreign species of fishes introduced in
it and that happens to be the US.
Canada falls out at 17 foreign species, Mexico with 33, and Hawaii
with 45 species of foreign fish.
