2.  A sea lamprey is a parasitic, eel like fish
that is gray-blue on its back and silver
white underneath.
 It is from 30.48 - 50.8 inches long.
 And it has a tooth lined, disc shaped
mouth.

3.  Itentered
Lake Ontario
through the
St. Lawrence
River.

4.  Atlantic Ocean
and the
Mediterranean
Sea.

5.  Thesea lamprey
sucks the blood out
of certain fish like
the lake trout. This
reduces the
population of many
important affected
native fish.

6.  There has been a massive invasion of the
Great Lakes since the Welland Canal
opened in 1929.
 The populations of lake trout and other
important game and commercial fish has
been drastically reduced. This affects a
multi-billion dollar industry.
 Efforts to reduce sea lamprey populations
have been successful, allowing for
successful efforts to restore lake trout.
 However, sea lamprey populations are
increasing again.

7. • Male sea
lampreys need to
be trapped and

use lampricides
to kill lamprey
larvae,
