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.

Tenkara in Siberia: Some Beautiful Presentations

Tenkara in Siberia presents many beautiful images. It is written in Russian, but I did not feel the need to translate at this point. I was content, as you might be, to peruse the site and take in the imagery. I am fairly noncommittal about the Tenkara fascination. I get the short line, intimate, minimalist concept. I love many of the fly pattern concepts and think them more than worthy to ‘traditional’ fly fishing presentations. Give Tenkara in Siberia a visit and enjoy the effort. It you are totally into Tenkara traditions then you will enjoy the site, if you don’t already visit it. Get your translation tools out. Also, here is an additional piece re joining the lines used in Tenkara from Troutrageous.
