Abstract
This project reports on the activities of the Shediac Bay Watershed Association under the
New Brunswick Wildlife Trust Fund, Atlantic Salmon Conservation Foundation for the year 2015.
The group has worked on different aspects regarding fish habitat.
Three Electrofishing surveys have been done in three sites on both the Scoudouc and
Shediac rivers. The sites were chosen to measure the impact of restoration projects and provide
data to evaluate restocking possibilities. We found brook trout in all three sites and two sites had
salmon parr present.
Restoration work was done on three sites. The first site on the Shediac River had issues
with fish passage because of abandoned beaver dams. These were removed and the bank stabilized
with native trees and shrubs. The second site with fish passage issues is an elevated culvert also
along the Shediac River. A 10 foot aluminum fish ladder was installed to allow fish safe passage.
The third site on the Scoudouc River had excessive bank erosion that was remediated using a
retaining wall, tree deflectors and native tree plantings.
Many educational activities on fish and their habitat were done during the project. Two
classes in the local school participated in the Fish Friends program to raise and release young trout.
They received presentations and a field outing. The SBWA had a kiosk during the summer at the
Shediac market. The Association also prepared a newsletter and an online presence for this project
on the website and Facebook page. Finally there was some coverage in the media on different
aspects of this project.

1. Introduction
The Shediac Bay Watershed Association (SBWA) is a not-for-profit organization located
in Shediac, New Brunswick. The SBWA was founded in 1999 as a result of growing concerns
among residents from various local communities over the ecological health of the Shediac Bay. A
Board of Directors, representing the various communities found within the 400 km2 watershed
boundaries, oversees its activities. The Association deals with issues related to water quality and
habitat integrity.
The Shediac Bay Watershed Association has been enhancing our coastline, rivers, brooks
and streams for over a decade. Our watershed has recovered from a series of setbacks and is now
in an improved state of environmental health. One of our priority goals is to enhance the numbers
of the natural salmonid populations. The Shediac and Scoudouc rivers and their tributaries have
potential for ideal spawning habitat. This project is also designed to engage and educate the
stakeholders who have a vested interest in the health and use of the two rivers.

2. Project results
The Association worked on four areas for this project: electrofishing surveys, trout
restocking, habitat enhancement and education.
2.1 Electrofishing Surveys
Electrofishing surveys from the years 2005, 2014 and 2015, showed that there is a
confirmed presence of Atlantic salmon parr (Salmo salar) and brook trout (Salvelinus fontinalis)
in both main river systems within the Shediac Bay watershed, namely the Shediac and Scoudouc
Rivers.
There’s a need for better information related to the population numbers and trends of
salmonids in the Shediac Bay catchment to be able to draft a management and restocking plan.
According to local anglers, various fish species densities drastically decreased over the last two
decades in both Shediac and Scoudouc River systems. Brook trout populations in the Shediac and
Scoudouc Rivers have been depleted for a variety of causes, namely: habitat degradation;
recreational overfishing; and commercial (by-catch) mortality. In recent years, much has been
done to address these factors.
The Association has trained its biologist and received permits to do electrofishing surveys
to gather data around restoration sites. The figure 2 demonstrate members of the field team
conducting electrofishing survey. The surveys are done immediately after the restoration work is
completed to provide a snapshot of the current life in the degraded habitat, then surveyed again in
the following years. This information will serve as a baseline to evaluate the impact of the
restoration work.

2.2.1 Scotch Settlement (EShdB-01)
This site is located in the McQuade Brook, a tributary to the Shediac River. It was accessed
through a private property with landowner permission, at 566 Scotch Settlement Rd. The site is
upstream from the bridge on Scotch Settlement Rd, approximately 170 m from the intersection of
Maclean Crossroads Rd.
This is a restoration site from 2014, and the transformation of the habitat after one year is
significant. The habitat was described as degraded by the presence of beaver dams. The substrate
was covered with thick layer of sediment and was characterized as; 5% rubble, 5% gravel, 30%
sand and 60% fines. There was erosion along the riverbanks due to the loss of trees from beaver
activity. Most importantly, there were vast accumulations of woody debris spanning the full width
of the bank, on a 100 meter stretch of important spawning habitat. One section was so dense and
filled with sediment, the water course created a channel through the bank in order to flow.
One year after the cleaning of the wood debris, the heavy loads of fines sediments have
been flushed out to reveal clean gravel bars, sand bars and natural riffles. The substrate can now
be characterized as: 15% rubble, 55 % gravel, 25% sand 5% fines. Some sections, mainly located
along meanders, still have fine sediments accumulations that will continue to be washed out over
time.
The length of the electrofishing survey site is 45 meters, and it breaks down into
approximately 20% run, 34% riffle and 46% pool. The channel width is an average of 5.4 m, wet
width average of 3.2 m and average depth of 12.4 cm. The water flow was calculated at 0.024
m3/sec and the water velocity was calculated at 0.66 m/sec. The water temperature was measured
at 17.92°C, and the visibility was good. The overhanging vegetation for the left bank was described
as 40% and 25% for the right bank. The percentage of undercut bank on the left bank is 15% and
5% for the right bank.
This site had 6 species of fish present in the survey. This is one site surveyed that had
Atlantic salmon present. There were 3 Atlantic salmon parr (Salmo salar) found, and the total
lengths of two salmon 12.5 cm and the third was 15.0 cm. Also at this site, 1 brook trout (Salvelinus
fontinalis) of 16.0 cm in length was found. See figure 4 and 5 for salmon and trout comparison.
The most common species was the blacknose dace (Rhinichthys atratulus) with 62
individuals collected. Also counted during the survey were 23 common shiners (Notropis
cornutus), 30 threespine stickleback (Gasterosteus aculeatus) and 1 white sucker (Catostomus
commersoni).

When comparing results one year after the restoration work took place, we can observe an
increase in most species caught, mainly the blacknose dace, common shiner and threespine
sticklebacks. The white sucker a bottom feeding fish was found in 2015 but not in 2014.
When looking at our salmonids, we see a decrease in brook trout but what intriguing here,
is the new presence of Atlantic salmon, where 3 individuals where found and none were caught in
2014. See figure 6

2.2.2 Dionne Brook (EScdB-01)
This site is located in the Dionne Brook, a tributary to the Scoudouc River and it was
accessed through a private property, for which we have permission from the landowner. The site
is upstream from the bridge on Route 132 next to Dionne road in Scoudouc.
The habitat here was modified by a severed erosion issue caused by a meander located in
an old agricultural field. The soil is loose and only held by grasses, allowing this branch of the
Scoudouc River to continuously erode in this section. This erosion problem is causing heavy loads
of fine sediments to be discharge into the brook, therefore covering the substrate and modifying
the habitat.
This site is a restoration site for 2015, therefore the electrofishing survey described below
will serve as a before snapshot of the populations living in this degraded habitat. For restoration
work details, see section “Habitat Enhancement”.
The substrate was described as: 35% rubble, 15% gravel, 30% sand and 20% fines. This
specific section is located directly above the severely eroding meander, it was chosen due to lower
water levels and for safety. The meander and the site directly downstream of it were not ideal for
electrofishing survey due to alder overgrowth and thick layers of sediments, making movements
with electrofishing gear near impossible.

The length of the electrofishing survey site is 60 meters, and it breaks down into
approximately 68% run, 7% riffle and 25% pool. The channel width is an average of 8.3 m, wet
width average of 5.7 m and average depth of 42 cm. The water flow was calculated at 0.344 m3/sec
and the water velocity was calculated at 0.160 m/sec. The water temperature was measured at 8.65
°C, and the visibility was poor. The overhanging vegetation for the left bank was described as 65%
and 80% for the right bank. The percentage of undercut bank on the left bank is 5% and also 5%
for the right bank.
This site had a total of 9 species of fish present in the survey. We found 1 Atlantic salmon
(Salmo salar) and 1 brook trout (Salvelinus fontinalis) of similar lengths, 11.0 cm and 11.5 cm
respectively. The most common species was the blacknose dace (Rhinichthys atratulus), with 41
individuals collected. There was also 14 white sucker (Catostomus commersoni), 34 common
shiner (Notropis cornutus), 1 golden shiner (Notemigonus crysoleucas), 21 threespine stickleback
(Gasterosteus aculeatus) and 1 ninespine stickleback (Pungitius pungitius). See figure 3.

2.2.3 Pellerin Road (EScdF-01)
This site is a previous restoration site from 2014. It is located in the Scoudouc River, and
was accessed by a small bridge on a dirt road called Pellerin Rd, connected to Lino Rd. The site is
upstream from the bridge, and the habitat was modified due to the presence of beaver activity.
The substrate remains covered by fine particles with a small amount of sand, with an almost
negligible amount of rubble and gravel (5% rubble, 5% gravel, 10% sand, 80% fines). The slow
transformation of this site is possibly attributed to the slow water velocity.
The length of the electrofishing survey site is 33 meters, and it breaks down into
approximately 79% run and 21% pool. The channel width is an average of 3 m, wet width average
is also 3 m and average depth of 28.5 cm. The water flow was calculated at 0.271 m3/sec and the
water velocity was calculated at 0.283 m/sec. The water temperature was measured at 12.6 °C, and
the visibility was poor. The overhanging vegetation for the left bank was described as 5% and also
5% for the right bank. The percentage of undercut bank on the left bank is 25% and 5% for the
right bank.
This site had 6 species of fish present in the survey. We found 2 brook trout (Salvelinus
fontinalis) of different lengths, 7.0 cm and 16.5 cm. The most common species was the blacknose
dace (Rhinichthys atratulus), with 31 individuals collected. There was also 9 threespine
stickleback (Culaea inconstans), 7 white sucker (Catostomus commersoni), 16 common shiner
(Notropis cornutus), and 1 golden shiner (Notemigonus crysoleucas).
When comparing results one year after the restoration work took place, we can notice an
increase in the blacknose dace, threespine sticklebacks and white sucker fish. We see a decrease
in golden shiners and common shiners. The absence of fourspine stickleback may be explained by
the time of year of the surveys: in 2014 the survey was done in the month of August, and in 2015,
the month of October.
When looking at our brook trout, the results are very similar: 3 caught in 2014 and 2 in
2015. See figure 8

2.3 Trout and salmon Restocking
Before embarking on a bigger restocking project, the Association must continue to do
populations assessments and habitat assessments to determine restocking possibilities. This data
needs to be gathered in order to apply for a restocking permit “License for Introduction and
Transfer” with the Department of Fisheries and Oceans.
The electrofishing results have shown the presence of brook trout and salmon in both the
Shediac and Scoudouc Rivers. Their presence is already an indication that there is suitable habitat
in our watershed, and is one indication that restocking is in fact a possibility. We have been making
good progress in this pursuit of data, thanks to our surveys from 2005, 2014, and 2015. There is a
need to continue the surveys and expand the population and habitat studies.
For the past 2 years, the SBWA has been raising trout eggs in a classroom aquarium as part
of the Fish Friends program. In June of 2014, approximately 100 juvenile brook trout where
released in the Shediac River. In June of 2015, 148 juvenile brook trout where released in the
Scoudouc River. This program allows us to begin restocking on a small scale.
We have done a site visit with the Friends of the Kouchibouguacis to see the methods used
for incubating salmon eggs in streams. They will provided salmon eggs that will be used in the
Fish Friends program and subsequently will be released in the Kouchibouguacis River in 2016.
This program could be a possibility for the Shediac Bay Watershed.

3. Habitat enhancement
Two sites were selected for habitat enhancement that was funded by the Wildlife Trust
Fund, Department of Fisheries Recreation Fisheries Partnership Program and the Atlantic Salmon
Conservation Foundation.
3.1 Beaver Dams
This site is located in a tributary to the McQuade Brook, a tributary to the Shediac River
and it was accessed by MacLean Crossroad road, approximately 0.3 km from Scotch Settlement
road, or 2.3 km from Shediac River Road. The access point is at the culvert and the site is upstream
of the road.
These sites had significant fish movement impediments caused by the presence of beaver
dams. Four large beaver dams along a brook caused large areas to be flooded with warm stagnant
water which were filled with sediment and significant summer algae growth.
The habitat between the beaver ponds was mostly fine sediment with negligible amount of
rock (10% rubble, 10% sand, 80% fines), and the pond’s substrate was covered with thick mud
(10% sand, 90% fines). Surrounding vegetation consisted of razor grass and mixed forest beyond
the riverbanks, providing 0% vegetation cover over the flooded areas.
The 4 beaver dams covered a 225 meter stretch of this stream. These were old abandoned
beaver dams with large amounts of sediments trapped within them. The dams were removed
manually, with the help of shovels and rakes.
The process began with removing the surface wood, then staff used shovels to reduce layers
off the top of the dam. As we reached the surface of the water, less than 8 inches off the top of the
dam was reduced per day, in accordance with the guidelines provided in the watercourse alteration
permit. This limit of 8 inches is to reduce the amount of sediment being discharged per day.
The strategy consisted of beginning to reduce the 4th and further dam, then make our way
down to reduce the next 3 dams downstream. This method was recommended by provincial
biologists.
Once the flooded areas were drained and dried, approximately 95 trees were planted to
eventually provide shade and help with stabilization of the banks. The team then spread clover
seeds throughout the entire area where there was exposed soil, covering a surface of approximately
5,200m2 or 0.5 hectares.
All trees planted consisted of native species, such as white spruce, tamarack, balsam fir
and red maple. The trees were provided by transplanting trees from the woodlot of “Vert l’Avenir”
farm in Grand-Digue NB. The clover seeds used where a mix of red and white clover, purchased
at the Farmer’s Co-op in Moncton NB.

shows addition cleaning and tree planting.

3.2 Dionne Brook Bank Stabilization
The SBWA identified a severe erosion problem in the Dionne Brook, a tributary to the
Scoudouc River. A meander in an ancient agricultural field was continually shifting and eroding
in the loose, nutrient rich soil, containing no root system other than grasses. This erosion was
creating heavy loads of sediment that covered the substrate on a 475 m stretch downstream of this
site.
An 18 ft. (5.5m) retaining wall was built into the eroding bank in the meander. The wall is
a combination of 3 sections of 6 ft. (0.9m) in width, and 24 inches (0.6m) in height. Each section
of the wall was built with 4 pieces of 6 ft. lumber, of 6x6 inch in size. The 4 blocks were attached
with 5 metal rebars of 7 ft. in length, bended at the 6 ft. mark. The rebars were provided and bent
by Tri Province Enterprise.
Each segment of the retaining wall has three 4 ft. blocks inserted into the bank. To achieve
this, 9 trenches where dug manually on the edge of the bank, then each section of walls were
lowered in the water, aligned with the trenches. Once the walls were in place, the trenches were
filled with layers of rocks and the same dirt that was dug out.
Once all retaining walls where installed and all trenches filled, trees were planted and straw
was used to cover and retain the soil. In total, there were approximately 45 trees planted on a 50
meter segment of the site.
On both sides of the wall, deflector trees (Balsam fir), were installed along the bank using
7 ft. metal T-Bars and metallic wire. The deflectors where installed on a 30 meter stretch, mostly
upstream of the wall where the erosion was most severe. The deflectors were installed according
to the guidelines in the manual “Ecological Restoration of Aquatic Degraded Habitats”, prepared
by the Dept. of Fisheries and Oceans, 2006.
Figures 11, 12 and 13 shows before photos and the work process of this site.

3.3 Fish Ladder
The SBWA installed a 10 foot aluminum fish ladder on an older elevated culvert in the
McQuade brook, a major tributary to the Shediac River. The culvert was identified as being an
impediment to fish migration upstream of the bridge towards suitable spawning areas.
In 2014, the group did significant restoration work upstream of this culvert. This included
beaver dam and debris removal, and tree planting on the riverbanks.
There are numerous fish ladders in New Brunswick, mostly wood and cement structures.
This novel structure is the only one in the southeast region made of this heavy duty aluminum
design.
Atlantic salmon and brook trout has traditionally used this stream during spring and fall
migrations but the numbers of fish have certainly dropped in the last 40-50 years. Restoring
healthy populations is one of the primary mandates of this watershed group.
16
A good point about this ladder is that it can be detached and relocated whenever the elevated
culvert is scheduled for replacement. Figure 14 shows the installation process of the fish ladder.

4. Education and Public Awareness
Education is an important focus for the Shediac Bay Watershed Association. The SBWA
takes advantage of various opportunities to present its projects to the public. We also seek out
teachers at local schools that have an interest in receiving classroom presentations and activities
on various environmental topics. Our regular displays usually emphasises our dedication to water
quality, salmonid populations and fish habitat enhancement by means of stream restoration.
4.1 Fish friends Program
Both classes of the third grade of the Monseigneur François Bourgeois elementary school
in Shediac were recruited for the Fish Friends program.
The aquarium was set up in one of the classes in the first week of March, during the school
break. The SBWA picked up brook trout eggs the following week, from the “Miramichi Salmon
Conservation Center” and brought them to the school.
A small introductory presentation was made during the delivery of the eggs, and some
questions were asked to the kids to assess their current knowledge of fish and determine their level
of understanding.
The next presentation explained the family of the salmonids, and the various species within
this family, including; brook trout, brown trout, rainbow trout, Atlantic salmon and the various
species of Pacific salmon. This presentation also gave them an introduction to the life cycle of
salmonids, which were explained using the classic diagram and videos of spawning salmon, eggs
hatching, etc., procured from Arkive.com.
The third presentation delved deeper in the early life stages; the habitat requirements for
Alevin such as shelter from predators, the yolk sac and the threats to their survival. The students
we’re then told to look for the next stage of development before starting to feed the fish. Figure 15
shows trout in the aquarium and a classroom presentation.
The fourth presentation took a step back to look at the bigger picture of fish habitat. They
were taught what constitutes a watershed (or catchment) and the differences between freshwater
and saltwater sources. The habitat requirements taught the students about: physicochemical
properties for water quality (dissolved oxygen, temperature, pH, etc.); plankton and
macroinvertebrates for food; the importance of streamside vegetation for canopy cover and
erosion; substrate types and the damaging effects of sedimentation, woody debris and plants for
shelter, etc.
A fifth presentation was on the great migration of the Atlantic salmon. The episode of “The
Magic School bus – Goes upstream” was shown in class, and was a great overview of the obstacles
and dangers in the journey to the spawning ground. The episode also did a great summary of the
life cycle, as the characters of the show became salmon eggs themselves and grew through all life
18
stages. The kids were questioned verbally on what they retained, and we believe the animation
gave a better understanding and helped summarize all previous presentations.
The final activity was the release of the trout during a field trip in June, before the end of
the school year. Each student was given a jar with 3-4 trout to release in a small healthy stream,
perfect for trout parr as it is too small for large predatory fish. The small stream is a tributary to
the Scoudouc River. A total of 148 trout were released that day. . Figure 16 and 17 shows pictures
of the release of the trout during the school field trip.
Once the main event was completed, SBWA staff did a quick sampling for
macroinvertebrates with a kick net, to show kids what can be found under the rocky substrate.
Also, freshwater mussels found on an adjacent site (Margaritifera margaritifera) were shown to
the student and differences pointed out between mussels found in saltwater habitats.
The students were very excited and also sad to say goodbye to the fish they raised and came
to love. Teachers were enthusiastic with the quality of the presentations and are looking forward
to participating again in 2016.

5. Conclusion
This WTF project has given the Association the opportunity to continue involving local
stakeholders in restoring local rivers for salmonids.
Restoration work has been done in two areas around the watershed and new areas have
been identified for the coming years. A fish migration issue has been addressed through the use of
a fish ladder of an elevated culvert.
The participation of the schools in the Fish Friends program was a great success and will
certainly continue.
We hope to continue the collection of information to develop a restocking plan for
salmonids in the Shediac Bay Watershed, to sustain recreational fisheries and ecosystem integrity.

Fish ladder installed to help Atlantic salmon population A group of volunteers brought a fish ladder to culvert to help salmon get back to their home
CBC News Posted: Sep 09, 2015 6:04 PM AT Last Updated: Sep 09, 2015 6:52 PM AT
The hope is that this fish ladder will help Atlantic salmon get back to their home and increase their population.
(CBC News)
A heavy duty, aluminum fish ladder was installed today in Scotch Settlement to help Atlantic
salmon return to their spawning ground, with the hope fish populations will rise.
A group of volunteers, spent the morning lugging 210 kilograms of aluminum to a culvert. Fish
ladders are usually made of cement or wood, but this one is made to last and help salmon return
home.
Jim Weldon is the project manager with Shediac Bay Watershed Association.
"The species of fish will travel up this brook, rest in this pool then they'll use this fish ladder to
access habitat further upstream," said Weldon.
"Now the main species that we're targeting are Atlantic salmon, sea trout, eels and we think
gaspereaux and smelts will probably use this stream also."
Jim Weldon is the project manager with Shediac Bay Watershed Association. He helped put up
the fish ladder. (CBC News)
Weldon guesses this culvert is at least 60 years old. The problem is, the gap makes it hard for
fish to get back up stream.

"That ladder will fill up completely and there will be a good stream of water that they can easily
swim up as oppose to trying to jump and smash their bodies against the culvert which obviously
injures them and makes them weaker."
Jolyne Hebert is the group's environmental technician. She says habitat preservation is key in
improving fish populations, but the work isn't easy:
"It was baby steps coming down the hill and coming down through the woods and getting it
through the river and into the water," said Hebert
"Once it was in the water it was a little easier because it could float but it was very interesting
and it was a good team work effort."
The group is hoping with time salmon will return in greater numbers.
Should the culvert be rebuilt sometime in the near future, the fish ladder will be taken to another
area where fish are having problems going upstream.
