Shock treatment for marine mammals
From ANIMAL PEOPLE, September 1997:
Bob Fletcher, president of the 200-vessel
Sportfishing Association of California, is touting a
high-energy ultrasonic anti-sea lion device, developed
by Pulsed Power Technologies, of San Diego, with aid
of a federal grant. According to Los Angeles Times
hunting/fishing columnist Pete Thomas, the device
produces “a brief concussive wave of energy that
affects the inner ears of mammals close enough to be
affected.” Fletcher told Thomas that it makes sea lions
“take off like scalded dogs.”
Added Pulsed Power Tecnologies president
Dick Ayres, “The fur huggers won’t be happy with
anything that annoys marine mammals, but this is by
far the most effective and least intrusive device that has
come out.” The west coast fishing industry, including
Fletcher, is lobbying in support of a recent National
Marine Fisheries Service recommendation that it should
be allowed to start killing pinnipeds “in situations
where California sea lions and Pacific harbor seals conflict
with human activities, such as at fishery sites and
marinas,” if nonlethal deterrents don’t work.
