Alaskan officials have cut down or banned King Salmon fishing in much of Alaska because so few of the large fish are returning. The Anchorage Daily News has an excellent informative article on the matter.
There may be several reasons for the end of healthy King Salmon runs and the usual suspects such as large ocean trawlers netting up the fish at sea, global warming, acidification, habitat loss and so forth probably all play a part. The number one suspect is the ocean trawler fleet in international waters and anyone else beyond the jurisdiction of state officials.
Evolutionary biologists that study the affect of human interaction with the ecosphere have previosly found causal links or chains of occurrence between the loss of a healthy whale population and the change of Orcas from that food source to new prey such as seals, otters and so forth. Since human beings consume 25% of all life produced by photosynthesis on the Earth they are a kind of natural, thoughtless eating machine something like a major player in a laboratory culture. With coordinated intelligent thought that level of ecospheric interaction is probably sustainable, yet it requires very intelligent, judicious selection by design for renewing health ecosphere characteristics.
If the King salmon population is just in some kind of physical bi-polar mood swing that will reverse towards the positive side one day then it will be possible to get that 100 pound King on the line and into the freezer again, if one has a freezer and electricity to power it not generated by CO2 producing coal fired power plants.
It would be really good if all that carbon could be made into some kind of high-tech building product with some extra elements cooked in.
