To
the B.C. MLAs:
I
have just read the transcript
of Honourable Stan Hagen's remarks at the open BC Cabinet
Meeting on salmon farming. I believe I am one of the scientists
on the "other side," and feel there is additional information
MLA's will need to answer the questions of their constituents.
Recent media on salmon farming has raised awareness of this issue
considerably and therefore if you repeat Hagen's comments that
sea lice have always been around, many people will realize the
Liberal government is not well-informed.
I
have lived in the Broughton Archipelago for 19 years, studying
killer whales and dolphins. I have written four books, including
one with Random House. I am senior author on five scientific publications
in peer-reviewed North American and European journals. I am a
B.C. registered biologist, founder and director of Raincoast Research
(www.raincoastresearch.org)
and mother of two in a remote coastal community. I am the scientist
who first reported the sea lice epidemic in the Broughton Archipelago.
After years writing over 10,000 pages of letters to all levels
of government I decided to step outside my field and do aquaculture
impact research myself. As a result I have not only seen all below
first hand, but have communicated with the majority of world experts
on these various issues.
Sea
Lice
Minster
Hagen is correct sea lice have likely been around as long as salmon,
but the problem is simply that salmon farms have dangerously altered
the biology of one species marine louse. In a nutshell, sea lice
die when adult salmon carrying them into freshwater during spawning
migrations. In spring, therefore, there are no lice in coastal
waters to infect the very small juvenile salmon leaving the rivers.
Today however,adult wild salmon pass sea lice to salmon farms
where sea lice thrive as all parasites do on stationary, high
host densities. Even the lights used to promote salmon growth
further stimulate lice production. Salmon farms now offer an over-wintering
haven lice never had before.
Two
of our salmon species, the pink salmon and the chum salmon are
unique. What sets them apart is they do not spend a year feeding
and growing in the rivers. As a result they go to sea 4-5 times
smaller than any other salmon. Unfortunately the smaller a salmon,
the fewer lice it can bear. So when our little pinks and chums
go by the farms and pick up more than 1-2 lice, they are doomed.
I have recorded upto 68 lice per 3.5 cm fish. Much more research
is need to pin this down, it might be they can not bear a single
louse. Among the 2,000 young salmon I have examined from Vancouver
Island to Prince Rupert I found pinks and chums with lice do not
grow properly. My research predicted an unbelievable 81% crash
of pink stocks in the Broughton Archipelago and in fact 98% failed
to return. This decline is greater than any recorded in the history
of this coast. The senior DFO scientists who examined all possible
causes found only sea lice linked all 8 affected rivers (PFRCC
2002, see http://www.fish.bc.ca/).
The extent of this collapse is typical to Europe and eastern Canada,
where salmon farms and wild salmon meet in confined waters. I
accept sea lice are not the only problem, but when a phenomena
such as this jumps around the planet with one common variable.
That variable (salmon farms) should raise suspicions. When Hagen
counts 40 sea lice scientists he is counting the people who published
on salmon collapse due to sea lice in salmon farmed areas such
as Norway, Scotland and Ireland. No one is publishing contrary
results.
I
can tell you, that I have been given a very rough ride for making
this discovery here. My two years of work on this has not provided
me a salary. I completed it with the help of international experts,
because I am deeply concerned. I have produced two papers, at
various stages of completion. Presentation of this work has been
requested at five major conferences and workshops (unprecedented
in my career and indication of the serious nature of this event).
I
am alarmed salmon farming companies clearly chose to ignore the
very stringent regulations designed in their home countries to
prevent exactly the crash we saw here and will likely see again
this year. For example, despite being considered the leading cause
of the biggest BC wild salmon collapse in history, BC salmon farmers
have continued to refuse to reveal crucial data on how many lice
they have on their fish. If they were not a source of lice I would
think they would make their numbers available and allow me on
their farms. In Norway they must report lice numbers on
the 15th of every month or face fines in the range of $100,000
daily (depending on how many fish they have) and jail if
they fail to comply (Martin Iversen Martin.Iversen@nforsk.no)
Escaped
Atlantic Salmon
Minister
Hagen is mistaken in drawing the conclusion that escaped Atlantic
salmon will not colonize the BC coast, because the experiment
failed in the 1940-50's. The conditions between now and then are
so different no such comparison is valid. Sixty years ago they
released small Atlantic fry into rivers such as the Cowichan that
were teeming with salmon. Today there is a stead drip of mature
fish, already acclimatized to Pacific waters, entering the marine
environment and these fish are finding their way into BC
rivers and are spawning. Very important to note is that 68% of
freshwater fish declines (and salmon do have a freshwater phase)
are due to exotic introductions and 77% of fish declines due to
such introductions are attributed to non-native salmon. Science
has already made it clear moving salmon outside their native environments
comes at great risk.
In
2000, I conducted research on Atlantic salmon caught in Fishery
Management Area 12. In 6 weeks I documented 10,826 Atlantic salmon
coming aboard commercial salmon boats and examined 775 of these
fish. While government proposes these fish are not fit for survival,
I found evidence otherwise. In a three week period the number
of recently escaped Atlantic salmon with wild food in their stomachs
escalated from 0 on day to 24.4% at the end of three weeks. Finding
and consuming food is considered the first and greatest hurdle
for an animal to survive in the wild. These results were published
in Morton and Volpe 2002 Alaska Fisheries Research Bulletin
Vol. 9 No. 2 (get
PDF). These fish are already colonizing this coast. Atlantics
are an aggressive species born out by the fact there is only one
salmon in the Atlantic. To allow it access to the orchestrated
balance we have between five species is truly to throw a wrench
into the works.
"Sockeye
Disease" IHN
IHN
is an infectious virus of the rabies family. It is found in sockeye,
but lies so dormant in the marine phase of this species researchers
can not find it. When sockeye spawn, there have been outbreaks
in freshwater. If an enhancement hatchery becomes infected with
IHN they must kill the fish and dry the facility, to prevent spread
of the disease. Salmon farmers report 1/4 of their industry is
infected and do not follow this protocol.
A
paper sponsored by the BC Salmon Farmers Association used DNA
to determine there have only been three transmissions of IHN from
wild salmon to farmed. From those three infective events, years
of chronic reinfection among the farms have sustained and spread
this strain of virus. For example, they theorize 4.5 million Atlantic
salmon smolts spread over the Broughton Archipelago and Bella
Bella became infected with IHN when the vessel transporting the
smolts sucked up the virus via their water circulation as they
passed a cluster of infected farms off Kelsey Bay. They found
further evidence the seawater outside the Browns Bay farm fish
processing plant was similarly contaminated.
This
means salmon farmers introduced IHN infected Atlantic smolts to
the Broughton and have sustained this virus, not normally found
in saltwater, for the past 16 months with no end in sight. While
Heritage and Stolt killed 3 million infected smolts in this area
alone, when the virus was passed to fish nearer to harvest size
Heritage opted to grow them out. They finally finished harvesting
these infected fish for human consumption, in November. Two months
later IHN flared up in their harvest-size fish at the nearby Sir
Edmund Bay site. Now they have restocked the original infected
site only a short distance downtide from Sir Edmund Bay. DFO tests
show a particle can travel 10km on one Broughton tide and IHN
virus can survive in seawater for 42 tides. They will never get
rid of IHN with type of management.
However
this is not solely a farm salmon threat. DFO reports 25% of herring
challenged with the virus IHN died. All the herring that spawn
in Kingcome Inlet are currently passing the Heritage infected
farm at Sir Edmund. Even though IHN normally occurs in sockeye,
remember it is at such low levels in the saltwater that scientists
can not even find it in sockeye. As the Minister's entourage on
the Broughton tour noted, infected fish offal is leaving the Sir
Edmund site and mingling with the wild herring. There can be no
such thing as quarantine in net pens.
I
have responded to these events by sending samples of infected
farm salmon and the adjacent wild herring for IHN DNA sequencing
to out of country labs. I regret DFO is not here studying the
potential for Heritage's IHN outbreak to kill the wild herring
stock of this area. As with the sea lice, I sense I am going to
have to initiate this work alone and without dedicated funds,
because this concerns me greatly. Herring, like pink salmon are
an essential energy resource to this ecosystem.
I
cannot escape the impression Heritage is fouling their own waters
and cannot possibly be considering a long-term industry here.
They are not alone. Omega, and Pacific National Aqua are also
heavily infected. I am also wondering where Health Canada is in
all this?
Benefits
to Coastal Communities
I
live in Echo Bay, in the Broughton Archipelago. We are in the
heart of the most densely salmon farmed area of this coast. While
we bear the potential costs of this industry i.e. loss of a million
dollar pink salmon fishery, displacement of killer whales (Morton
and Symonds 2000), loss of tourism favoured marine anchorages,
toxic algae blooms (heterosigma), gunfire over water to
kill seals, Atlantic salmon in our waters etc. our community is
dying with no benefit from salmon farming. We are being reduced
to one day a week of postal delivery, the salmon farmers are discouraged
to fraternize with us, they do not live here, shop here, put their
children in our school or in any way benefit this community.
While
tensions are very high at times and the local First Nations have
repeated zero tolerance of salmon farms I hope you will note there
has not been one act of vandalism on the equipment salmon farms
leave unmanned throughout this area. I am very proud of my community's
level-headed response.
Employment
is very low on salmon farms. Indeed, farms call in every hour
because there is only one person on some sites. In addition, while
the industry has opened fish processing plants, many wild plants
had to close due the price collapse caused by farm salmon. Sointula
lost it's only two wild fish plants and significant employment,
Port Hardy has lost several and none of this is even factored
in. Low prices also inhibit skippers from taking as many deckhands
per boat and fewer and fewer can afford to maintain their vessels
(an industry unto itself in many towns here). I seriously doubt
there has been any net gain in employment on the north island
due to salmon farms.
As
far as the international viability of this industry I would recommend
any examine the current crisis within Pan Fish, one of the biggest
international forces in salmon farming.
Ecological
Footprint
In
my estimation Minister Hagen mis-uses the term "footprint," when
describing the range of impact of these "farms." It would be naive
to think the only space a salmon farm leaves a mark on is the
area of the cages. When a fish farmer throws several tonnes of
food into the water every day and reports 3 to 1 growth ratio,
you can know tonnes of waste are being released from these farms
daily. While the ocean has enormous flushing capacity, the Broughton
is flashing "overload" warning signals in the blooms of species
such Noctiluca, the constant bubbles rising from the seafloor
in areas of Sir Edmund Bay, the 81% infection rate of lethal sealice
loads on pink salmon (1.6lice/gram host weight) and other factors.
If we could see the sea floor, we would see an ebbtide and flood
tide trace of waste deposition. We know it can't simply just vanish.
"Well-sited" only means deposition happens somewhere distant from
the farm. The prawn fishermen of my area are familiar with the
farm waste signature, foul smelling mud adhered to traps and no
life (due to the rotting process removing all available oxygen).
I
cannot imagine these operations would be allowed on land with
prodigious waste distribution beyond their leased boundaries.
But more than that it is my sense netpens are not working for
the salmon farmers despite free waste disposal. The net barrier
not only allows pathogens and faecal matter out, is lets a host
of salmon pathogens in. Salmon are designed to keep moving and
thus leave all their "problems" behind. But when natural pathogens
move into a farm, the sick and dying mingle unnaturally with the
healthy. This is why a paper in the Canadian Journal of Fisheries
and Aquatic Sciences dubbed salmon farms "Pathogen culturing
facilities" (Bakke and Harris 1998).
Prince
Rupert
The
Minister might also be incorrect to suggest the Prince Rupert
Regional District hired a biologist to do baseline monitoring
of the area to be farmed there. I believe it was the David Suzuki
Foundation that hired a local biologist to carry out that very
important work. The Regional District office does not seem aware
of having funded such work.
In
Conclusion
I
think each of you must be very careful in placing too many eggs
in the salmon farming basket. If the industry can co-exist with
wild fish so be it. However, I have combed the literature, and
corresponded with many looking for one place on earth where salmon
farming is co-existing with wild salmon and found there is no
model. Further to that I must report that my research has made
it clear that salmon farmers discarded many restrictive regulations
designed by their home countries to combat wild salmon mortality
when they came to BC. So when a community becomes dependant on
salmon farms, I can only wonder how long that will last and at
what cost. Because here in Echo Bay we welcomed salmon farms,
but are dying of it today. Many salmon farmers south of Cape Caution
appear in free-fall due to IHN and Kudoa, a parasite they are
reluctant to talk about which liquefies their fish days after
harvest. This is a familiar pattern with the Sechelt industry
collapsing and having to move to the Broughton. Now the Broughton
is IHN loaded and they are moving north again. My own experience
gives me the impression salmon farms are on a fifteen year cycle.
Thus I think it is essential there be wild fish left when this
industry moves on or looses its market. The decline in the wild
fish required to feed farm salmon alone should be alerting us
to the finite nature of salmon farming.
Wild
salmon on the other hand have infinite capabilities. Where wild
salmon thrive so thrive the forests (the majority of nitrogen
in watersheds comes from salmon), human communities, tourism and
a myriad of non-salmon fisheries.
I
hope this helps in addressing your constituents. Because if they
are listening to the radio or reading the newspapers they will
know many of Minister Hagen's answers are not accurate.
Respectfully,
Alexandra
Morton, R.P.Bio.
