T&T: Illinois Carp Barrier

[Ron Rogers]

THE CONCERN BY THE CORPSE AND OTHER BUREAUCRACIES SEEMS MISPLACED. MAYBE
THEY SHOULD ASK THE EXPERIENCED MANUFACTURER (BELOW) - OR WOULD THAT BE TOO
LOGICAL? The poor Corps of Engineers colonel just got back from Iraq and
inherited this. He would probably prefer to go back and get shot at.

Vancouver, Washington - December 12, 2006 - Smith-Root, Incorporated (SRI)
has developed an electroanesthesia system for use in a wide array of fish
culture applications. "This system is a new application of our previous
electrofisher technologies. It is now available to the fish culture
community as a safe, effective way of handling and anesthetizing large
numbers of fish without the need for regulated chemicals," according to Jeff
Smith, the company's CEO. "In light of recent concerns with CO2 in Europe,
we think our electroanesthesia unit could be of great value to commercial
fish farms," he noted.

The Model EA-1000A Electroanesthesia Unit is available directly from the
company. It is a high-voltage, direct current (DC) pulsator that emits a
complex waveform capable of anesthetizing large numbers of fish or other
aquatic organisms for handling, marking and tagging operations. "The varying
electric field first excites the fish, then puts them into an anesthetized
state," said Smith. He added, "The electrical output of the EA Unit is
engineered to induce the mildest possible physiological reaction by the
fish." The output controls can be adjusted to anesthetize quickly and
deeply, with minimum power.

Smith noted that his company's system has been used very successfully in the
U.S. at Columbia River fish hatcheries (e.g. Bonneville State Fish Hatchery
in Oregon and Carson National Fish Hatchery in Washington). These and other
facilities where the Smith-Root EA Unit is now in use spawn thousands of
salmon on an annual basis. "SRI's Electroanesthesia Unit eliminates the need
for chemical anesthetics, so that spawned-out salmon can be sold or rendered
immediately, without any required waiting period," added Carl Burger, the
company's senior scientist. The electrical waveform is applied in successive
stages, each having selectable voltages, waveforms and durations. "This
gives the hatchery manager or fish culturist many options in selecting the
best combination of settings for the targeted species," stated Burger. "The
system is designed for precise control in a variety of fish culture
environments and is a safe alternative in reducing costly handling labor at
farms and hatcheries," he added. The Chinook salmon anesthetized and spawned
at some of the hatcheries in the Northwest U.S. are sold to commercial
vendors after spawning, for further processing and marketing.

Smith-Root, Inc. can design a system that meets exacting needs and
specifications, including custom-built holding tanks and elevator arrays for
moving large numbers of fish into treatment tanks. The company also designs
fish counting systems, backpack electrofishers, electrofishing boats, and
electric barriers to control predators or limit the movements of fish
populations, including desirable cultured fish or non-desirable invasive
species. The company currently operates an electric barrier in the Chicago
Shipping Canal (heavily used by boat traffic) to prevent Asian carp
populations from entering the Great Lakes. SRI also manufactures electric
barriers to successfully control sea lamprey and carp in many other locales.
"Our Electroanesthesia Unit represents a great tool for use in fish culture,
and can save managers lots of time and money over the long haul," Burger
said.

SRI plans to pursue the development and testing of new "high-tech" tools for
the fish culturist. Smith-Root is a Vancouver, Washington-based company with
over 40 years of experience in the design of innovative conservation tools
and electronics for fishery scientists, managers, biologists and fish
culturists. Contact the company directly for additional information.

" Can anyone enlighten me?"

I think Joe Pica on the Carolyn Ann will chime in soon - he is stuck waiting
to get through.  Evidently, you can completely disconnect everything
electrical on your boat and pay $600 and get towed through.  Pay the troll
under the bridge!  Our government at work.
