Lionfish
Threat Grows
It might be cold and snowy across much of the country, but, in our warm
coastal waters the lionfish invasion continues. These beautiful and
exotic marine fish threaten to seriously disrupt the waters they are
invading and focusing on harvest continues to be the primary management
strategy. While it is unlikely that harvest can control lionfish in
large areas, it could prove to be quite effective in some locations.
The New York Times has
done an excellent video that provides a great overview of the problem.
If you are not familiar with the lionfish invasion this 5 minute video
will teach you a lot.

Every month it seems that there are good stories about
lionfish harvesting. This issue we are highlighting the story of Vic
Depuis. A South Carolina resident who is on a mission to eliminate as
many lionfish as possible. He has developed new collecting
equipment, organized tournaments and energized divers all to help slow
the spread. Read more
Where Will Our Next Invaders
Come From?
New research shows that
the greatest threat of invasive species introduction comes from within
the United States and not from outside the country. "Our findings have
significant implications for biosecurity policy and the need to
consider security measures beyond established national borders," said
Matthew Thomas, professor of entomology, Penn State.
The researchers found
that, while all the top 100 known exotic insect pests for the entire
U.S. already exist in the country, the top lists for each of the states
included many species that are yet to establish in those states. In all
cases except one, the absent pests do occur somewhere else in the U.S.
and more often than not, they are found in a neighboring state. In
fact, 12 states had every pest species that they were missing located
just across their borders in a neighboring state.Read

San Francisco Bay Fights
Ballast Water Introductions
The maritime shipping
industry brings 8.4 million metric tons of cargo into California each
year, along with it come some unwelcome visitors: exotic species of
marine life that hide out in the ballast water that the ships pick up
at sea.
When ships from around the world reach California, they
discharge all
this water from their cargo holds - and everything else that happens to
be in it.
Local scientists say more foreign species have invaded the
Bay-Delta
estuary than anywhere else in the world - and some of them are
seriously destructive. State officials are preparing for a showdown
with ship owners, who are responsible for removing these invasive
species from ballast water.Read

Invisible Invaders
Invasive plants and
animals are the subject of much research and managers are constantly
working to develop new programs designed to manage, control or prevent
the spread of these invasives. However, an entire class of invaders
often goes unnoticed. Microorganisms have the capacity to devastate our
fish and wildlife resources and a new
scholarly paper helps to make us all more aware of the threat.
The authors of "Invisible invaders:
non-pathogenic invasive microbes in aquatic and terrestrial ecosystems"
provide an excellent overview of invasive microbes and offer a
compelling argument that significant new research is needed. Read

Carp Art
Lisa Murch is an artist living and working in Philadelphia. She draws on her studies of
entomology,
biology and zoology in her
sculptures and installations. Hearing the news stories about Asian carp
she was inspired to create a new sculpture she titled "Invasion". She describes the piece as " This
installation captures a school of Asian carp working their way up
river."Read More
The Problem With Pike
Northern pike are great sport fish and in their native waters they
offer great fishing opportunities. Unfortunately, a few misguided
individuals believe that pike belong in all waters and intentionally
release them.These illegal plants often result in new populations
becoming established that cause many kinds of problems. Help to spread
the word that there is never a reason for anyone to ever move a live
fish from one water to another.
The New Mexico Department of Game and Fish is offering a
reward for information leading to the arrest of whoever put pike in
Eagle Nest Lake. A young angler caught a juvenile pike and reported it
to officials who confirmed the catch. Read More
In British Columbia, the Columbia River is being invaded by

A Christmas Poem
Les Mehrhoff, Chief Botanical

with a reworking of the classic poem The Night Before Christmas.
Lee says of his version, "...in the spirit of the holiday season that I

students for years, now with a new twist, the perspective of an
invasive species biologist."
