The Salmon People along our northern Pacific coast now believe their favorite fish needs to be protected like the spotted owl.
MATTOLE VALLEY, CALIF. -- Salmon poached, salmon grilled, salmon
mousse -- however you like it, nowadays it is abundant the year
around at moderate prices, thanks to fish farming. Great quantities
of the tasty fish are raised for market in hatcheries, thus ending
our dependence upon the natural vagaries of harvests from the
ocean.
Not everyone in the Pacific Northwest is happy about this. An
indeterminate number of people are dedicated to the proposition
that there were once huge quantities of salmon spawning in coastal
rivers and streams, but their numbers have been decimated by
logging. Often this dedication is acted out in efforts to thwart
logging -- still important to the economy of the region. Some
concentrate on "restoring" watersheds in the belief that logging
and ranch roads cause a great deal of silt to run into the region's
rivers, making them shallower and warmer. They claim the warm
water, in turn, kills off countless young salmon smolts.
So dedicated are some of the Salmon People that in Oregon they
have been clamoring to demolish several dams because, they contend,
the salmon cannot get up the fish ladders made for them, thus
preventing them from spawning upstream. Some object to federal and
state fish-counting officials including in their tallies of salmon
those fish released from hatcheries.
The goal of the SPs seems to be to create conditions in which
wild salmon populations can steadily increase, just as human
populations do. The goal rests on the mystical belief that had it
not been for logging and ranching in these parts, the salmon
population would be soaring.
Alas for the salmon, they cannot mirror human population trends.
Humans adapt to virtually any kind of environment and temperature.
Humans engage in a great range of activities. Salmon have no such
variety. They are born, swim downstream, go to sea for
approximately three years, swim back upstream to their birthplace,
spawn and die. No matter what we do for them, neither we nor the
salmon can control nature. Thus, their population goes up and down
as a result of changes in the carrying capacity of their complex
environment, both streams and the ocean.
Before humans entered the salmon's environment there were
floods, droughts, landslides, hot temperatures and predators. There
still are. Contrary to pictures of "ideal" salmon streams conjured
by the Salmon People -- shaded, tranquil, cool -- research shows
that salmon-spawning streams subjected to sunlight and disruption
produce more fish than do streams "managed" by humans into a
steady, unchanging condition.
Rainfall has a good deal to do with successful reproduction by
salmon. For example, in the early Eighties, on a tributary of the
Eel River, two families were logging a tract of Douglas fir they
owned. Keep in mind that fish-and-game officials count carcasses of
recently-spawning salmon as a way to estimate population. On this
creek in 1980 they counted 250 salmon carcasses. By 1984, the count
was down to 87. Neighbors sued the owners, arguing that their
logging was causing the decline. In 1987, however (three years
after the tiny 1984 crop was born and thus the time for them to
come back to spawn), the carcass count was 2,187. That same year,
the largest commercial harvest of salmon in the 20th Century was
recorded. Unlike the early Eighties, 1987 was a wet year. In
Garberville, California, the town nearest the creek in question,
one foot of rain was recorded between November 15 and December 15.
Since the salmon spawn in the fall, when the rains come, it is
these early rains that are critical to their success.
As for "cleaning up" watersheds, removal of man-made trash --
old autos, farm implements, plastic -- is desirable both
aesthetically and to make sure poisons don't leach into the
streams. Any benefits from preventing sediment caused by soil
run-off, however, are uncertain. There have been no studies made in
the wild on the effects of sediment on fish health or survival. All
studies have been made in laboratories under controlled
conditions.
Most people cannot tell the difference in flavor between
farm-raised salmon and wild salmon. Like the tree worshipers who
try to stop all timber harvesting, the Salmon People see in their
minds' eyes a utopia that never was: fish reproducing happily and
in huge numbers, unbothered by untidy human activity. For them, the
first stop on the way to this utopia is to tell people they must
not use their land except in strictly limited ways. And so the
fight goes on.
Oh, waiter, I'd like the cold, poached salmon and a glass of
Sauvignon Blanc.
