Stream keeping in
the rain out in the forest is a real pleasure at this time of year.
Everywhere life is bursting forth from
emergent fry to nesting birds, trees beginning to flush with spring growth.
Salmonberry sprouts emerging from the forest floor makes a nice snack when
walking along the streams, just realized that’s the perfect snack in the bush
for a stream keeper.
We have our smolts
counting fence in place with around 20 fish so far moving through all around
115mm to 135mm with a couple of nice trout around 200mm.
Giant Water Bugs
find there way into the box on occasion, around 35mm they look formidable with
the ability to suck the meat out of a fish leaving only skin and bone. Handle
with care and off they go back into the stream.
Some Hog Weed
eradication is another project we tackle at this time of year and after several
years we seem to be holding it at bay isolated to one spot.
Removal is by hand
with extreme care not to get the sap onto your skin, as it is toxic.
Clearing Broom is
safer though more daunting as it seems to grow as fast as you cut it. Broom now
can be found way up in the bush as well as around suburbia, though a nice
looking flower it does out compete native plants.
Down in the
estuary life also is bursting forth with Geese nesting, Red Wig Blackbirds,
Ducks of all shapes and sizes and even the Beaver is busy at this time
repairing there dams and building them higher to contain more water for the
upcoming summer months.
With the huge
returns of Wild Salmon last year we are expecting that this years fry salvage
project will be a big one with more fry emerging from the big spawn last fall
than we have seen for over 25 years.
Wild Coho are a
species that was so abundant within the Salish Sea that fishing the adults was
the easiest salmon fishery around. In front of Lantzville every resident that
had the ability to fish would be found morning and night trolling or mooching
out in front of Winchelsea Islands.
It did not take
too long to limit out your catch and this was true for the whole of the Salish
Sea. For some reason, loss of habitat, Hatchery over production, the stocks of
Salish Sea wild Coho plummeted from the early 80’s onward.
Pumping thousands
of Hatchery [fish factory] Coho into every stream from here to there in a vain
attempt to bolster stocks proved to be a catastrophic failure with the
continued decline of genetic diversity the stocks of wild Coho declined almost
to the point of collapse.
Back in the height
of the Coho crisis DFO applied a coast wide closure with the exception of
certain fishing lodges who had whined that there businesses would suffer so
they got exclusion zones around there lodges. Habitat loss along with over zealous transplanting of these
factory fish almost brought the Wild Coho to extinction.
A few but sad to
say not all stream keeper groups around the coast stayed away from the hatchery
model of recovery even though this meant they did not get access to the huge
funding opportunities that installing a hatchery would entail.
As with every
thing in life when money enters the picture it seems all common sense goes out
the window.
I have heard many
times that if you would only build a hatchery you would have lots of funding
and something for the volunteers to do over the winter.
Real stream
keepers have no problem finding projects to do if they are truly active and
want to really help the environment not only fish but also all flora and fauna.
Many groups fall
into the trap of bureaucracy becoming heavy with meetings, planning committees
etc, chasing funding leaving no time to walk the streams and see how nature
works without money or frivolous endeavours to sate the ego more than help the
environment.
When decisions are
made without regard to what is actually happening in nature and money becomes
the driving force then failure will surely follow.
Most stream
projects have no follow up or ongoing monitoring once the checks are cut.
The best projects
come from years of watching how the streams function then you come to the conclusion
that most of what you may think needs doing does not.
Leaving well
enough alone does not come easy as humans we have a tendency to think we know
best.
Stream Keepers April 2014-03-30
April is upon us, cherry and plums trees
flowering everywhere you look, buds on the trees and fish emerging from the
substrate. Soon all the Wild Chum fry will be gone from the streams and the
young wild Coho will be occupying the pools. Chums become free swimmers very
quick and once this takes place off they go to sea going on their great trek
around the north Pacific having the largest range of all the Salmon species.
According to records the largest Chum caught was in Edie Pass BC weighing in at
42 pounds and 44 inches long, now that is one big Chum. I have caught many in
the 10 to 20 pound range and believe me when you get a Chum on a light rod and
reel you have a good fight on to land the fish. If in the river you have no
chance if they decide to head down stream at a alarming rate of speed peeling
off your line until it breaks or if strong enough line the fish becomes
exhausted and then you can muscle them to shore so I can only imagine hooking
into a 42 pounder. One of the longest migrations back to the spawning grounds
takes place on the Yukon River, Mackenzie River and on the Amur River in Asia a
true marathon swimmer by any standard. Last week we placed our smolts’ counting
fence and box at Swan Lake to catch any early outgoing Coho. With the box in
place we will visit it twice a week until the main out migration begins in
earnest then every day to count and empty the box.
This last week we have had some torrential downpours that
have brought high levels of flow to all our streams and being a warm rain it
seems to be melting any snow still laying in the upper watersheds contributing
to flows.
From February to May is the spawning time
for Sea Run Cutthroat Trout often the unseen visitor to our streams. Wandering
into and out of the streams all year and sometimes to over winter within the
stream. The young can spend up to 3 years in the stream before heading out to
sea living for about 10 years if they can survive being over fished and habitat
loss due to urban planning placing many of there traditional small streams
within storm drains.
Lantzville had a very productive Cutthroat
trout stream, Slogar Brook flowing from Negrins farm down through the Kennel
property over Leyland Rd and Peterson, Sebastion roads finally flowing down the
beach into the Salish Sea. I doubt if many even spawn there any more, though
ever the optimist I expect there are some sneak in and spawn. There are some
resident trout and hopefully some will return to the sea as sea run. One local
who lives at the creek told of his son catching them on a regular basis and a
long time resident who used to live on the creek tells of listening to them at
night making there way upstream splashing along from pool to pool. Bloods Creek
has a good run and so does Knarston sometimes they can be confused with a late
run of Coho but chances are they are Cutthroat often seen in February heading
up to spawn.
This is a important time to be aware of
what you allow to enter the watershed via your septic tank, roadside ditch and
now the sewer which you may get the false sense of “Oh its okay we now have a
sewer so I can dump anything down the drain or toilet but and this is a big but
you must remember that all sewers lead to the Ocean as we still have this idea
that dumping sewage into the sea is out of sight out of mind. Our sewer system
flows to Hammond Bay Road pumping station and treatment facility where it
receives minimal treatment [chlorine injection and sedimentation] before being
pumped out to sea. If it was just human waste the ocean can easily break that
down but with modern living we tend to use all kinds of chemicals usually not
even knowing what they are hidden behind that appealing label or slick TV ad.
Even medical waste from medication [birth control pills] has been attributed to
gender bending among resident river fish where sewer is dumped into rivers.
Live smart and think about the bigger picture because we are the only animals
on the planet who have the arrogance and ability to effect often to there
detriment all other life as we know it on this planet we call Earth as it takes
its ever spinning journey through the universe.

March has come
rather fast this year as February goes out with hopefully a last blast of
winter weather. Though I herald the arrival of snow for it’s role in watershed
re-charge I would like it to remain up in the hills and mountains and not
covering my garden just as I start to get more active pruning, weeding etc.
March as I said
last month will bring the
[hopefully] Herring spawning along our shores.
Just the other day I read a paper by -
Iain
McKechnie, Dana Lepofsky and Ken Lertzman,
“The
baseline (data) that is used to assess biomass of herring and the allotment to
the commercial fishery only begins in 1951,” said McKechnie. “The data doesn’t
go back far enough, and it conveniently limits the goal of recovery as well.” The west coast herring fishery was closed for four years between 1968
and 1971 after a complete collapse of the population. DFO documents note that
even after numbers rebounded, “some previously-favored spawning locations were
no longer utilized on a regular basis.”
Oral histories from fishermen and First Nations people
describe spawning areas and fishing grounds that were productive over
generations, with native place names such as Ch’axa’y (Sizzling Water) and
Teeshoshum (Waters White With Herring Spawn). Bone samples collected at
Teeshoshum are composed of 90 per cent herring over 800 years, but no spawning
has been recorded there since 1998.
As
you can read we have done these very important fish a disservice through miss
management which when you take into account the loss of forest cover and
further miss management of our wild Salmon stocks you can see clearly why now
is the time to take a serious look at the whole ecosystem we call the west
coast and lobby government to take some drastic steps to try to get us back on
course to a sustainable environment.
When
I say sustainable I do not mean sustainability in the sense the word is bandied
about these days in a feel good way while ignoring the inevitable collapse of
our collective ecosystems.
To
be sustainable is to live within the means of our environment, not keep coming
up with new reasons to move the goal posts.
This
is no more evident than on the central coast where we all get a good feeling at
the creation of the Great Bear Rain Forest touted as the savoir of the Bears
and the once mighty forests that shrouded the coast which now as you read this
the logging corporations are still going along full bore just over the hill out
of sight of any marine traffic preserving what they call the visual corridor.
So
while we all catch the Herring fever few realize that this is one if not the
most destructive fishery we have on the coast which has such nock on effects
that we cannot collectively comprehend the magnitude that this fishery has on
all other fish stocks along our coast.
When
was the last time you enjoyed a plate of fresh Herring for lunch or dinner??
Never I often hear when I ask this question, a sad statement when at one time
Herring did play an important role in the diets of the peoples of the west
coast.
Among
our first nations folk roe on seaweed was a very important food source, fires
all along the foreshore roasting Herring was a regular sight now but a distant
memory.
So
here is a favorite recipe of mine for Star Gazey Pie if you are lucky to get
some Herring.
Vegetables
of choice or what you have available chopped into small chunks, sauté in olive
oil with onions and garlic, remove from heat and prepare your fresh Herring by
removing the internal organs and gills but leaving the head intact, [de scale]
place veggies in baking dish with a little extra olive oil and some crushed
tomatoes or a little water and tomatoe paste , salt and pepper, then carefully
place the whole Herring around the pan with heads towards the middle.
Next
comes the tricky part, prepare your favorite pastry recipe for a one crust pie,
[ the one on the Crisco box works great, freeze the Crisco and then grate into
dough] roll out to fit pan, now you have to lay the crust on top and for the
tricky bit gently slice the dough so that the Herring heads stick up out of the
top of the crust in a nice circle around the centre of the pan. [Star Gazing]
Bake
at 425 for 30 to 40 minutes until crust is nice and brown. You can brush with
egg white to get a nice even brown to the crust before you place in hot oven.
Serve
with a nice salad of fresh greens with, if you can get some seaweed. The sea
weed you see growing along the rocks that looks like a hand waving, [Fucus
distichus ssp. Evanescens] common name Rockweed, not too appetizing looking
when fresh. Pick from a non polluted spot then blanch in boiling water and it
will turn a nice green then add to salad, yum.
When
picking seaweed to eat always go to the most remote spot you can find along the
foreshore away from any form of pollution.
The
Salish Sea has such diversity that due to our collective recklessness we have
allowed the depletion of what was once one of the most productive bodies of
water in the world.
Pulp
Mills, Chemical plants, Oil Refineries, Industrial run off and licensed
discharge [so called safe limits, ppm], Storm drains, [road runoff] Sewage
discharge, [often unprocessed or at best minimal]
Household
chemicals, Etc.
Down
the drain and into the sea, out of sight out of mind.
I
could go on and on but you get the picture we have collectively allowed all
this mostly due to government inaction and always being subservient to
industry. [Oil sands, we all know how destructive they have become and the
potential for even worse case scenarios if allowed to ship from our coast.]
In
the year 2014 there is no sensible argument for any of the aforementioned to be
allowed when weighed against the health of not only humans but also all flora
& fauna that inhabit this coast. I know its jobs etc but we can have those
jobs just not the pollution they create. The root cause is Profit and greed so
much so that now greed is considered an attribute to be admired as we all rush
to achieve the consumer of the year award.

Stream Keepers February.
Rain, we finally had some, seems like it is
odd to herald the coming of rain unless in the middle of a drought but rain and
more rain is what we need for the streams. If you go walking in the hills you
will notice that most wetlands are more on the low side as opposed to
overflowing which is the norm for January. Low rain events over the winter combined with low
snowfalls does little for the re-charge of our watersheds. The rain has little
chance to soak into the ground with the surface dry most water runs off towards
the nearest stream or wetland without soaking into the ground and eventually
re-charging the aquifers beneath.
Somewhere out there is an equation to
calculate how long it takes water [rain] that has soaked into the ground to
reach the aquifers and eventually discharge through wetlands, springs and
evaporation. [It takes a long time]
As we know forests can create their own
weather and rain events from the evaporation given off by the trees, if you
look towards the mountains during one of those now rare wet periods you can see
moisture flowing out of the trees like wisps of cloud rising from the forest.
Lately the only weather we have seen
created by the trees is from all the fog we have been getting as the fog
condenses among the needles creating rain beneath. This does bode well for the
trees but does not give enough to recharge the wetland and aquifers; we need
lots of rain for that.
Planting trees is one of the most rewarding and helpful
experiences the volunteer’s do outside of salvaging fry.
To plant a tree gives the volunteers a
sense of ownership and pride when that tree eventually pokes its top above the
shrubbery and starts it journey to become a mature tree, hopefully many
hundreds of years old before it falls to continue its cycle of life and death
unhampered by mans need to cut them down.
That is the nice thing about the estuary that being a nature
preserve we have great expectations that any tree that survives the Deer
browse, the Beavers lunch, Voles or Mice chewing them to feed on the bark and
any other natural misfortune they may experience we will see them reaching for
the sky.
This also holds true to a certain degree
for any tree planted by the side of any stream but the sad thing is that around
human habitation trees tend to get cut down either for a view or paranoia that
they may fall on the house.
Many years ago we had a tree that was
around 100+ years old growing beside the road when the neighbour said he was
going to cut it down as he stated he did not trust it, I replied ‘Trust it, how
can you not trust a tree, it is not going anywhere and is not going to ask to
borrow any money” and it is on the road right of way therefore not yours to cut
down, his reply was that it may fall down, of course it may fall but also it
may not as a mature Douglas Fir [menziesii] can live for a 1,000 years and
around 200 years when seed production reaches its peak so as you can see most
trees you can see on any given day is no more than a teenager far from the once
mature trees which made this coast what it was prior to removing the vast
majority of the coasts forest cover. Connect this to the productivity of our
wild Salmon and you can begin to understand the great loss we have experienced
this past mere hundred years. [Of course I came home one day and the tree was
cut down] A true tragedy of the commons.
Down in the estuary at the head of the bay
we had one flood where the streams overflowed their banks and created flooding
all the way back to the rail tracks just short of the Petro Can station at NW
Bay Rd during that one and only large rain event we did have. The water was at
one was point not much more than 6 inches from topping NW Bay Rd at one
location, this demonstrates the speed in which our watersheds discharge when we
do get some rain. Under normal [if there is such a thing] conditions the rain
would soak in and discharge much slower taking days for water levels to rise,
now we se it occurring the very next if not the same day as the rain. This can
lead to Salmon eggs being flushed out of the substrate or being buried too deep
for the fry to emerge due to heavy sediment loads washing off the land via
roads and ditches leading directly to the streams. Speaking of roads we have
thousands of kilometres of asphalt roads, which leach out toxic hydrocarbons
into the environment. A recent study on leachate in road runoff was conducted
to see what if any effect this leachate had on Coho Fry, water samples where
taken and introduced into a tank with Coho fry from roadside ditches that had
no vegetation, the result being that most Coho died from the toxic run off.
The next test was with water flowing off
the road into a vegetated ditch which had the result of no mortalities when fry
where introduced showing how the vegetation has the ability to filter out a
portion of the toxins. As a result today if made aware of this most road
maintenance crews stay away from so called cleaning of ditches and instead just
maintain the culverts with a hand shovel to clean out any blockages.
Recently we have looked at the possibility
of opening fish access above the highway at the fire hall on Knarston Creek.
This will take the form of a fish habitat survey [fisheries level one survey]
from the Salish Sea to the upper watershed. This will quantify the habitat
parameters and allow us to see if it is possible to open up this long neglected
habitat.
In years past some fry salvage was done on
Knarston when time and conditions dictated and these fish where placed in
Dumont Marsh for year round habitat. Some of these fish will residualise if
they cannot get out to the Salish Sea but most if not all will migrate down the
stream to the sea either as 1+ year olds or as two year+ olds. Anyone who went
along the shore at Knarston this past fall will have had the treat of seeing
many Wild Coho jumping along the shore, this does not mean that they were all
awaiting the chance to enter Knarston because a lot of these fish could end up
in any one of the streams around Nanoose Bay or even further like Nanaimo river
and other streams around Nanaimo or even all the way up towards the Englishmen
River.
Without an active tagging program we can
only guess the streams these fish will spawn in.
Coming up over the next two months is also
a good chance to see the major forage fish during its annual spawning run along
the shore, the once mighty Herring.
Like the once mighty forests we had humongous runs of Herring
every year spawning like a great silver wave hitting the coast from San
Francisco in the south to Alaska in the North.
Like a tidal wave these once abundant fish poured onto the
beaches spawning in their millions providing a food source for all the fish in
the sea and most important for our young salmon exiting the streams in the
spring.
Take some time towards the end of the month and into next
month to walk to the beach and witness one of nature true marvels before it is
all gone.
Due to mismanagement of the resource through over fishing a
fish species, [ read East Coast Cod]which can spawn for several years during
its life cycle, taken solely for its eggs to sate an appetite in Japan. Last
year we had no shallow water spawning due mainly to a whole fleet of seine
boats being allowed to fish the stocks that were getting ready to spawn along
the foreshore of Nanoose Bay and Lantzville.
Enjoy nature as much as possible and all
its wonder, take the kids for walks so they can experience nature first hand
other than on TV and they may grow up avoiding what is termed Natures Deficit
Syndrome. That is when humans lose their connection with nature and experience
only man made landscapes.
When a city dweller gets a chance to walk
in nature the one common remark they all make is how good they feel after such
a walk, which shows how we all can benefit from a good walk along the foreshore
or in the woods.
If you can get the chance to visit the
central coast or as it has become known as The Great Bear Rain Forest do so as
soon as you can to truly experience a real rain forest before it is all gone.
Stream Keepers December
Merry holidays to all and thanks from the
fish who by now have most of their eggs firmly buried within the substrate of
our local streams once again continuing with their evolutionary journey through
time.
Awesome is the only way to describe the
returns of Wild Coho on all our streams this last month. Though a little late
on some streams they were a little early on others. I do hope you got out to
view these fish as they made there way up stream and if not you may still have
a chance as the late runs come in. You do not have to look too hard to see them
this year due to their abundance.
Bloods Creek Wild Coho were all the way
above the highway but due to lower than usual flows were unable to make it all
the way to Green Lake. Chum were seen within the lower reaches though once they
get past the highway they have a hard time moving further into the system. The
Wild Coho at one time moved all the way up into Copley Creek above Green Lake.
Due to a dam placed on the stream back in the coal mining days stopped this
upstream migration though the mining company did say they would build a fish
ladder it never came to fruition and only when the dam was gone did fish move
back upstream.
Knarston Creek had a good return moving all
the way to the highway where a hung culvert behind the fire hall stops them,
which is sad for the fish as at one time they went all the way up above the
highway in to the foothills like Bloods Creek. [Bad planning by highways or bad
advice when they redid the highway back in the day]
If you were into ocean beach fishing Knarston was the spot
this year as it seemed that all the Coho in the bay were of the mouth of
Knarston along the shore.
One report was out of 21 Coho caught only one was marked as a
hatchery fish with the adipose removed. They stayed along the shore so long
this year that upon returning into spawn they had turned black and red already
instead of being silver bright in the stream.
Even Dublin Gulch at the Nanoose rest area
had a small showing of Wild Coho pushing up from the beach, though only a small
number return and have limited spawning opportunities before coming to the
barrier falls. Well worth the short walk back up the stream to see the falls
especially when the falls are frozen.
Bonnel Creek was awesome with an early showing of small what
I would think were female Chum due to there small size followed by a really
good run of Wild Coho, which also brought in another flush of Chum this time
larger and more abundant. Walking the entire length of available spawning
habitat we were surprised at the amount of both the Coho and Chum throughout
the whole system, which bodes well for the future.
Recently a document came into my
possession, which showed data from the early 70’s when Bonnel had counts of thousands
of Chum. Also in the data was a prescription for removal of Beaver dams and
logs jams along with gravel removal, which went ahead with DFO approval. From
that year on the runs began to decline until the returning numbers went down in
to the low hundreds and even lower in some years. This was a case of putting
the cart before the horse so to speak, remove the habitat and the spawning
gravel and then the stream flows unhindered to the Salish Sea just like
building a big ditch. What was not considered was that entire habitat was
contributing to those large returns of Chum and Coho.
In the case this year on Nanoose Creek I had to keep some
volunteers from wanting to pull the Beaver dams as they thought they were a
impediment to the Chum from moving further upstream. Upon further walks
upstream Chum were found way above the highway showing how they could transit
those dams and any other log debris jams they encountered. The Wild Coho on
Nanoose were observed as far up as Matthew Crossing and beyond with another
spectacular run after all these years of slow returns. Again a good example of
just leaving the habitat alone and it will take care of itself.
Craig Creek had a good return also of Chum
and Coho. The Coho can go as far as the logging camp when flows allow which on
most years is as late as Xmas with the chum being restricted to the lower
reaches. In the days past a small Chum hatchery was placed on the lower Craig
to try to increase the numbers but as usual failed and the only achievement was
the further depletion of the wild stocks. When you have kilometres of habitat
for the Salmon to spawn unhindered you have to allow nature to take its course
even though man thinks he knows what is best for nature it does not always work
that way. [Ego]
As we know all Salmon and Trout’s have
adapted over the millennia to be able spawn and rear in each stream building
immunities and adapting to all the conditions specific to that stream even down
to the individual tributary. A Salmon is a Salmon I hear after all there brains
are no where as big as ours in fact they are about the size of a pea. Pea
brained they maybe but in size only and the more I find out about past
practices on our local streams I think it is the humans that made those
detrimental decisions that have the pea brain. Ever try to catch a fish? Sure
you can but many times you will be outwitted by that fish with only a brain the
size of a pea. Go figure. It was also good to see Black’y or one of his
offspring back down in the estuary at the head of the bay taking his fill of
Chum, which is the easiest for the bear to catch. All he has to do is sit in an
advantages spot along the banks or on a log and take his pick. Watching a bear
fish is wild to say the least, they tend to look uninterested then suddenly down
plunges his paw and bam there is a fish hang off his claws then up on the bank
or log if enough room and chomp goes a big chunk from the back of the head then
tossed into the pile. When they have time it is amazing to see peel off the
skin better than I can do with my filleting knife as they devour the rest
leaving the scraps for rocky Racoon, Mink, Otter and even the birds all taking
there share, even the flora gets a good hit of nutrients via the excrement
deposited throughout the forest.
Happy New Year to all and we all look
forward to the coming emergence from the gravel next spring of yet another
start of the incredible journey the Salmon undertake to complete their life
cycle once again.
Stream keepers January 2014
Where has all the rain gone, what was the
wet coast has been the dry coast so far this winter which for the fish maybe a
problem next year with limited recharge within the watersheds.
With a recent walk along Bloods Crk from Lantzville
Rd to the highway and above it was gratifying to see dead carcasses still
visible here and there. This section just below the highway is a hidden jewel
this close to the village core, a little difficult to walk down into the gully
but well worth it. { Possible park status ?]
This is the site of one of the volunteer
garbage cleanups we conducted in the past where we removed a big dumpster load
of garbage, it was good to find very little trash and no garbage dumped down
the bank.
With all the eggs tucked away within the
substrate walking the streambed is not advisable until the fry have emerged
next spring. With winter we get some sea run cutthroat venturing into our
streams looking for stray eggs and later on spawning opportunities for there
own offspring.
The small stream called Slogar Brook which
runs from the kennel property parallel to Lantzville road then down Sebastion
to exit on Sebastion beach at one time was a active spawning stream for Sea Run
Cutthroat as late as the 80,s fish were reported to be seen spawning.
The stream contains native Cutthroat, which
remain their whole life within the stream hence being on the small size when
compared to the Sea Run cutthroat. Due to urban devolpement the only continuous
wetted reach runs from the beach to Lantzville Rd.
Above very little wetted habitat is
available due to being ditched over the years and overall flows restricted from
diversions.
The only stream that was showing difficulty
was Craig Creek due to its flow going subsurface at Northwest Bay Rd. On recent
walks below the road we found carcasses and bits lying along the banks down to
the estuary at the Salish Sea.
In years past when we had been walking along the upper
reaches we encountered Wild Coho making their way upstream as late as January.
How do Salmon find their place of birth,
often asked I usually reply that they smell the river or stream of their birth,
smell how can that be they say so I go on to explain how a fishes brain is kind
of shaped like a Y with the thinking part at the Y junction and on either end
of the top of the Y are the olfactory organs which are connected directly to
the nose allowing the fish to smell the free molecules in fresh water and hence
can detect individual drops that come from the very same pool that they were
born into.
This is another reason that wild Salmon are
more able to survive than hatchery fish by passing on this trait to their
offspring, which in the hatchery environs does not occur.
A study done on sockeye showed that after
catching fish off Haida Gwai and blinding some fish while blocking the noses of
others resulted in only the ones who made it back were the ones who were
blinded. Another study found that when gravel was replaced with fresh gravel
often from a quarry the fish had a hard time finding a familiar place to spawn
due to the smell of the gravel being different, go figure something as simple
as smell would be one of the main reasons for millions of Salmon returning to
there home waters.
Trees which grow in particular soil types
also affect the PH of the water which in turn affects the smell that is why
when a different species of tree is re-planted the PH of the water exiting the
forest is changed further confusing the fishes sense of smell.
Over the holidays we planted native trees
right up to Xmas mainly down in the wildlife reserve at the head of the bay,
which contains Bonnel and Nanoose Creeks.
We still saw dead Chum laying all
throughout the estuary mainly due to the low flows and lack of rain not
flushing them out and most wildlife being sated on fish from the big runs last
fall. When they get hungry later
they may still munch on those rotten old eyeless Chum drifting around the
streams.
With all the eggs tucked away nice and snug
in their gravel we now await their emergence from the gravel this coming spring
to begin their epic life cycle and journey around the Pacific Ocean.
Fishy Fish
Estuary days
Still the water sits
Sleeping
Ripples stir the surface
Cronk goes Heron
Mother Salmon calls
The return begins.
