Irrigation for Fish Farming
We have been talking about irrgation in class the last couple of days and so I was surfing the net looking for a good irrigation topic. The irrigation we have discussed up to this point has had to do with irrigation for more traditional purposes such as growing plant crops. I came across this site that talks about irrigation in Idaho for trout farming, click on trout. Water is diverted into rivers and streams into man made canals and ponds just like other crop irrigation so that they water can be monitered for temperature and purity. 58 degrees farenheit is the ideal temperature for trout. The trout are raised for conservering their numbers in the wild, sport fishing, and are also sold to grocery stores. This link talks some more about trout farming in Idaho which is number one in the country in trout production. I guess not all irrigation water taken out of the rivers and streams hurts fish. In this case it helps them in conserving and managing their numbers, even if it's not in a natural way.

As humans we have a tendency to domesticate animals to make life easier (people have always been lazy). Plus it provides stability to a product that can fluctuate. Now this should not hurt the existing animals unless most of the wild animals are domesticated. This will allow fisherman to fish with possibility of greater number of trout in the streams. And the companies no longer deplete the rivers trout (any one who knows ecology well please point out all flaws, I really don’t mind). Makes good economic and environmental sense to me, allows the market to replenish a source that is depleting. If there is a market for trout the trout will be harvested one way or another.
As for the water part they should need to pay the fair market for the water rights.
Warning: The following is unsubstantiated; the way I heard it is more like urban legend than fact. Take it with a grain of salt.
When the dam over Flaming Gorge was built, sportfishing was wiped out because they used water from the bottom of the gorge to maintain water flow. It was too cold for the fish to survive. After enough people complained, they started pumping water from the top of the reservoir and brought in fish that could survive in the warmer water.
Hi there " JDH ch " --- I was in the search engines researching SEO Software when I came upon your blog..... I don't know if you are out of place in the engines, or I am out of place and just don't realize it :-)
