Wild Fish Endangered: Salmon Confidential Documentary

Wild Salmon in B.C. are suffering diseases heretofore unknown in the waters for returning wild salmon. Why? Some strongly believe the scientific data shows nearby fish farms are breeding disease that is infecting the passing wild salmon.

To whatever degree you mentally invest in wild, natural, nature, the environment, whatever your sense of balance in the natural scheme of things…this issue of fish farming and the possible/probable infestation of wild strains of fish should cause alarm.

Also, factor in the food supply (I wish advocates would leave out the “children” emotionality of their arguments…enough about the children emotional appeals on every topic under the sun) and the dangers of marketing tainted food. Watch the trailer for Salmon Confidential. The actual release is scheduled for mid October. More details here as well.

Industries, jobs, money infused into local economies, government stone walling, doctored research, expert vs. expert, advocates on both sides make these discussions/debates/arguments tiresome after awhile. Nonetheless, something is wrong in B.C. and many other waters around the world where fish farming is established.

Tilapia, the Invasive Choice

 

Michael Rupert Hayes, Hyco Reservoir, N.C.

The Issue
     "There are some serious trade-offs in aqualculture, evident in
the case of tilapia, one of a handful of fish breeds that are seen
as being the future of freshwater aquaculture.  The species is
highly carnivorous and its continued large-scale introduction could
contribute to the extinction of less aggressive, indigenous fish
throughout the world.  As aquaculturists recognize this and
research universities and institutes like the Consultative Group on
International Agricultural Research are experimenting with better
techniques and hybrids, development agencies such as USAID and the
World Bank continue to push for the spread of tilapia throughout
the world.  Tilapia is now being farmed in more than 85 countries. 
A lack of international and industry-wide regulation, coupled with
real food needs and implementing agencies' relative lack of concern
over species loss could mean that the destructive fish wins out in
a perhaps unnecessary trade-off between environmental, economical,
and food concerns." (more)

Well now, you can see that the U.S. has nothing to worry about the invasive nature of Tilapia in our waters. That’s their problem right?

Of course, those ever important and intrusive U.S. agencies, many have so much faith in, have been ever diligent to balance the habitat vs. entrepreneurial opportunities when it comes to Tilapia rearing. So fish farming of Tilapia is here in some degree. Where will those rearing ponds be in relation to waterways? The effort to farm Tilapia has been around in the U.S. for a good 15 years or more.

China’s Fly Fishing (a warning for the under or is it over managed, “put and take” mentality)

Tilapia (Invasive in SE U.S.)

Tilapia (Invasive in SE U.S.)

BLEAK ALERT! Habitat, Habitat, Habitat!

“Unfortunately, I found that most of streams in Guizhou Province were
hopelessly polluted and devoid of life. And even though I consulted some of
my more proficient fishing buddies and the websites of several fly shops, I
have yet to find a fly that will hook the elusive Chinese mudsucker that
inhabits the ponds around here. The few times I have ventured out all I
have managed to catch are small, curious Chinese children.”

“I realized that if I were ever to catch any Chinese fish I would have to
give up my high-fallutin’ fly fishing ways and resort to Chinese methods.”

“When the Chinese fish, they really don’t like to give the fish a fair
chance. Each person has four or five rods and they chum the water with
bait. Not to mention that the ponds are really small and people line up
shoulder to shoulder around them. I’m sure to the fish, it must seem like
swimming around in a jungle of hooks and bait.”

“The Chinese would like to fish with automatic weapons, explosives, anthrax spores, and weapons of mass
destruction. Unfortunately, the expense and the fear of bodily harm keeps
them from doing this. Instead, they mostly fish with long, collapsible rods
with a bit of monofilament, a bobber, hook, and bait attached. None of this
reel silliness. The bait is usually pellets of what looks like guinea pig
food or a powder that is mixed with water to make a bread dough-like
substance.”
