Four years after being spawned Fraser River Sockeye salmon return to the same creeks in which they were born to mate, spawn and die. Salmon have a strong preference for heavier returns every four years. Prior to 1913 this cycle peaked every second odd year (IE: 1905 - 1909 - 1913). However in 1913 (a year that had a record high 31 million fish harvested) construction of the Canadian Pacific Railway along side the Frasier river resulted in massive rock slides that prevented most of the returning fish from making it to their ancestral streams
. Clean up efforts in subsequent years and the construction of fish ladders at Hell's Gate saved the Salmon from extinction and switched peaked returns to every second even year (IE: 2010 - 2014 - 2018) but numbers of fish returning were way down. Until now
. This year's projected returns are the highest since 1913's record year and not far short of it. This is bound to make the organizers of Salute to the Sockeye
very happy. [more inside]

The SalmoFan: So long, and thanks for all the fish and animals, and plants...
Amidst the catastrophic decline of large ocean fish
, Salmon farmers can choose the hue of their "farmed" Salmon
with the SalmoFan
. [Meanwhile, these same salmon are fed on a factory fishing catch process which effectively strips most large life forms from the ocean.] With 1/4 of all mammmals
and 1/2 of all plant species
facing extinction, Is the planet truly at a crossroads
? Are we losing the extinction battle?
.."Overfishing is a global problem. People are taking marine life faster than it can reproduce. The world's catch peaked at 86 million tons in 1989, up fourfold in 50 years.....But many governments, including the United States, Mexico, the European Union, Japan and China, kept on pouring subsidies into commercial fishing fleets to keep them afloat...The Gulf of California in Mexico is not dead, but it is exhausted from overfishing, which has caused every important species of fish there to decline....Crucial fisheries have collapsed worldwide."
Contrast that with This
: "[once upon a time there were] cod shoals "so thick by the shore that we hardly have been able to row a boat through them."
There were six- and seven-foot-long codfish weighing as much as 200 pounds. There were great banks of oysters as large as shoes. At low tide, children were sent to the shore to collect 10-, 15-, even 20-pound lobsters with hand rakes for use as bait or pig feed. Eight- to 12-foot sturgeon choked New England rivers, and salmon packed streams from the Hudson River to Hudson's Bay. Herring, squid and capelin (a small open-water fish seven inches long) spawning runs were so gigantic they astonished observers for more than four centuries"
