Thanks for that Jim
I have a question then for everyone. Can the destruction of an entire river be justified to save one species of fish? I know this is a very emotive subject, but the use of rotenone to wipe out every living fish in a river catchment, and all the associated birds and animals that rely on the river for food is surely not the right thing to do?
Lets just say the Dee..and I hope to god it does not happen, gets infected. There are animals, birds and fish in that river that are protected by law. There are also commercial enterprises along that river that would also be effected such as Raemoir, Strachan, Glentanar, Loiriston lochs etc etc etc, and water extraction for distilleries, drinking water and bottled water.
I did a quick bit of reading on the waters that have been "killed" in Norway, and from the limited info available, it seems that these rivers where short, remote(ish) and had little in the way of farming, population or commercial enterprises nearby.
Obviously my views are very environmentally biased..living as i do with an environmental scientist, and although I believe that Salmon should be protected, I do not believe they should come any higher than other animals, fish or creatures. Fish genocide maybe....
Interested to hear other folks views.
