Thanks Jeff -

As folks have cited in recent threads salmon aquaculture has become a huge business worldwide and it's a good time to get strict about regulations and farming practices for this industry. There should be no more tolerance for (bio-genetically engineered quasi-triploid brood) salmon spills as there is for oil spills or radiation leaks. It's a form of biomass pollution and has nasty long-term effects including damage to the remnant populations clinging to existence, particularly in Maine.

<i>editorial on topic...FWIW</i>

Once again man leaves a snarled trail of blunders with the fate of wild atlantic salmon runs in the United States left in a over-manipulated, disregarded mess.

What took millenia for nature to build tethers on the brink in two centuries time. Now I am no expert but my gut feel says "give them what they need to survive and they will find a way". Free passage in both directions from their natal waters to their feeding grounds off Greenland, protection of their spawning streams, regulation of aquaculture practices, moratoriums on open seas harvest, etc. All of these might be unattainable, but each link eliminates a factor in their demise.

Free passage - a no brainer, if they can't reach spawning water they can not sustain their existence. This has driven more salmon to exinction than any commercial fishery.

By regulation I mean if the stronger cages (and other improved practices) can not be implemented the farm should not be allowed to operate or should operate in another location with adequate cage designs. The rate of escapement on both oceans (pacific ocean escapees also number in the hundreds of thousands) and on both hemispheres is a good indication that the cage designs are not adequate by today's controls.

The waste coming off a typical farming operation rivals the effluent generated by a community of 40,000 humans (because it is untreated).

The improved taste and color of farmed salmon we have all noted in recent years is due to the introduction of ferol bromide (savory taste) and xantaxanthan (coloring agent) into the feed, which is 60% oil.

Essentially we've taken a pelagic traveler from it's thousands of miles of open seas and forced an evolutionary path from it's Norwegian farm brood (30 years of in-breeding in fact) and crammed them into cages where they fatten for the table on pellets.

The reality is, our demand for salmon is so great it would be impossible to sustain without aquaculture. Our demands for electricity have required us to adopt nuclear generators too - but that does not mean we can allow hundreds of thousands of 55 gallon radioactive drums to escape.

Yes, I watch TV and eat farmed salmon. I also believe we should control escapement of the potential side effects of both into nature. As someone who appreciates wild salmonids deeply, the release of this farm brood is no less a form of contamination than the said 55 gallon drums. Not all may feel that way, but I think it's time for this industry to be viewed as the significant industry that is truly is, and time for it's harmful effects to be controlled.

As the alpha species on this planet, the challenge before us is whether we can keep on feeding our ravenous appetites for salmon while maintaining sanctuary for wild brethren to regain it's footing in the rivers and seas where it once reigned as the 'king of fish'.

Great reading from the Pacific Northwest (c/o Bob Ball's great site) <!--http--><a href="http://www.piscatorialpursuits.com/ubb/Forum3/HTML/000127.html" target="_blank">HERE</a><!--url--> on the topic of fish farms and the impact on indigenous species, etc.

Of particular interest is <!--http--><a href="http://www.edf.org/pubs/Reports/Aquaculture/" target="_blank">this article</a><!--url--> identified by Nate Mantua (who came and fished big girl with us last fall) of the University of Washington.
