Strikes against the Salmon...


Strikes Against Salmon...

A couple of weeks ago the State of Alaska was involved in some rather unsavory work as officers from the Department of Fish and Game enforced a subsistence fishing closure in the Yukon – Kuskokwim watershed. It was reported that at least 1000 pounds of fish were seized along with a few dozen nets and --- tickets were issued. The State denied these reports at first, but fell silent as pictures and videos began to surface on the Internet. The Anchorage Daily News even reposted a video of an Alaska ADF&G officer shown clearly cutting a net while confiscating Salmon from the nets of local subsistence fishermen. One of the enforcement officers even makes a comment near the end of the video, “We'll be back.”

In looking at the current state of the salmon fisheries in Alaska, one must be sure to understand the already present conditions. With the fact that Salmon are migratory fish that travel thousands of miles throughout their lifetime, assessing environmental risks to future Salmon stocks is quite encompassing. From the pristine creeks of the Nushagak watershed to the rocky streams of Southeast, the territories covered by Salmon in Alaska alone are expansive. Then when bringing into consideration the rearing and migration grounds of the Pacific Salmon, the area of concern becomes almost as large as the United States.


Water pollution from runoff, industrial processes, increased vehicular use of transient and spawning waterways changes the chemical composition of the water as does runoff from roadways and such.  It is proven fact that Salmon return to their home-stream by using their olfactory glands to literally smell their way through the oceans back to a tiny creek over thousands of miles... To complete their life cycle. What happens when you change that water's base composition by increasing the acidity is the Salmon's navigation 'warns' them away from that water. The cumulative effect of this is decreased returns to areas closest to the polluted water.  In a water system where aquifers are closely related and intertwine and simply determining which waterways are affected by any water change can be impossible.

“Alaska contains 63% of the total wetland acreage in the United States. Over half of the state is covered by wetlands and salmon are critical to the productivity of these ecosystems.” US F&W

Pollution in the sea and ocean acidification are becoming increasingly larger threats to fish stocks.  With increased water temperatures and higher levels of carbon based gases, Arctic fish in particular are losing their traditional rearing grounds as other species, including humans move in. The increase in Arctic trans-Ocean sea traffic will also reduce the ocean space available for generational fish stocks due to pollutants left behind and disturbances in the sea. The fish will adapt and returns will decline. A species group will only grow or sustain to the capability of their environment.

  Last year a huge mass of debris from Japan washed into the sea and shortly afterwards TEPCO,  the operators of the failed Fukishima Nuclear Plant dumped untold amounts of sea water that had been used to cool overheating reactor cores back into the sea. The Japanese government subsequently lied to everyone about radiation risks. There is still no true government response to this with any sort of preparatory contaminant monitoring or plans to contain any if found. Another aspect of consideration in thinking about the Fukishima disaster is this; who is responsible for the loss of economic impact if the fisheries do show signs of radiation contamination?

Global Climate Shifting, as the weather patterns relocating across the globe.  It has been well proven that the coastal areas of Alaska are changing. From increased vegetation in tundra areas to flooding along rivers, change is occurring, no matter what you want to call it.  Not long ago, some scientists did predict that certain areas, in particular the Arctic regions would experience some extremes. I can attest to the fact that Alaska has been experiencing some pretty extreme weather. This winter will go down as one of the harshest in recent history. But also this Summer has already begun as unusually warm and sunny.  These conditions are not addressable by humans in any other way than to simply become conscious about consumerism that contributes to human interference with nature.  But, we must be aware of the causes so that we can do something about the causes that we as humans can address the decline in fish stocks.

Poor returns in 1996-98, however, suggested a return to a level of productivity similar to the pre-1978 period (Fair 2003).  Fish from the 1996-98 return years reared in the ocean when temperatures were above average, whereas, cooler than average ocean temperatures characterized the pre-1978 period.” NOAA Report authored by Doug Eggers, Alaska Department of Fish and Game.

In Alaska, we also have to deal with commercial dragnet operations that aren't very well regulated. In fact, these commercial fishing boats were allowed to catch an unregulated amount of  bycatch until just a few years ago. Bycatch is the “unintended” harvesting of non-targeted species, for example a pollack trawler catching Chinook Salmon or a Cod Trawler raking Halibut from the ocean floor. The cumulative effect of years of dead wasting untold thousands and possibly millions of  fish is a large contributing factor to the decline in fish stock populations.  The entities responsible for most of the by-catch are actually supposed to be providing sustainable economic opportunities and solutions to the communities being hurt most by the harmful trawler fishing.  Sort of ironic huh? Recent regulatory changes have reduced the amount of allowable by-catch, however, even the industry acknowledges that enforcement oversight is nearly non-existent or effective.  More On This Next Time.

Have a great day folks...
