The document provides information from a community information session about Tassal's salmon farming operations in Okehampton, Tasmania. It summarizes the status of the salmon stocks, harvest plans, environmental monitoring activities, community sponsorship programs, and efforts to increase transparency. Some key points include: current fish weights are averaging 4.5kg, harvest is planned from November to December, environmental conditions have been favorable, community cleanups are ongoing, and monitoring includes water quality testing and benthic surveys.

2. The Farm
• Lease established for salmon farming in July
2017
• Fish inputted to sea in August/September
2017
• Currently x13 17YC pens on the lease
• Fish are an average weight of 4.5 kg
• Fish are performing strongly, with a
Feed Conversion Rate currently at 1.2
• Fish in water an average 15 months till
harvested
• 5-5.5kg average at harvest
• 18YC inputted in September completed in that
month
• Average weight 155g at input
• 18Yc inputted into x8 168m sanctuary pens

3. The Farm
• Environmental conditions have been favourable,
with both temperature and oxygen levels in the
parameters we were expecting.
• Temperature currently at 13’C
• 18YC biomass splits will occur in February 2019
creating 16 stocked pens.
• 18YC will end with a total of 24, 168m sanctuary
pens.
• Harvest starts in November

4. Harvest
• Harvest planned to start November 1st
• Harvest is planned to be completed by the
24th of December, weather allowing
• Harvesting on average 80T per day
• 5 days per week harvest plan
• Harvest occurs on the lease, the harvest
vessel will bring the fish to Paddy’s Point
for unload
• Fish chilled down on the vessel to under
3’C then fish offloaded to truck
• Five trucks per day to George Town on
harvest days
• Harvest staff 4 people on board, 2 night
time staff for off load, cleaning and
preparation for the next day

5. Our People
• We currently have 43 people
working on the Okehampton farm
• 45 people will be the full work force
by the end of the year
• 29 are full time, remainder on one
year contract.
• 33 of our staff live on the east
Coast between Bicheno and
Buckland
• Three work experience students
from Triabunna. One student
employed full time
• School based traineeships from
Triabunna starting next year.
• Majority of our staff working 2/3/2
shift.
• 18 full time staff at the Triabunna
Rendering Plant

6. Our Equipment
• Have x4 Lyndcraft vessels now in
operation all built in St Helens
• Local fisherman supports farm with
contract towing to support our bath
operations
• Contracting local fisherman to
perform net cleaning operations
• Another contract vessel to support
bath/harvest operations over
summer
• Ebeneezer feed delivery vessel
delivers feed to the feed barge
• Feeding is now done centrally from
Hobart

7. Central Feeding
• New high resolution cameras,
improved picture
• Winch camera positioning
• Vertical and horizontal movement
• Integrated oxygen and temperature
sensors
• Improved WHS for farm staff, not
having to get on barges in rough
conditions
• Improved feed conversion and feed
intakes
• Improved environmental outcomes
with reduction in feed wastage and
FCR
• Feed technicians work together and
focus on identical KPI’s

8. Fresh Water
• AGD is caused by the microscopic protozoan,
amoeba species Neoparamoeba perurans.
The amoeba occurs naturally in the ocean,
and attaches to Atlantic salmons gills
causing a condition called amoebic gill
disease.
• Juvenile salmon, especially those in their
first year out to sea, are particularly
susceptible to the disease. This is one
reason why we are focusing on raising
bigger big on land before they are
transferred to sea (we currently raise fish to
400g on land and aim to increase this size
with each generation).
• Increased water temperatures increases the
AGD infection.
What happens if we don’t treat for AGD?
• The amoeba will develop on the gills and
reduce the ability of the fish to intake
oxygen and release carbon dioxide. Initially
it can result in reduced feeding and reduced
growth. If left untreated will result in fish
death, as the fish would suffocate.

9. Treating AGD
• The amoeba can be dislodged from the gills
by treating the fish with fresh water. In the
wild salmon affected by AGD would swim
into brackish water to kill it, as our farmed
fish are unable to do this, we give them a
bath. Basically we place a liner at the side of
the pen, fill it with fresh water and provide
oxygen, fish are then moved into the liner,
they stay there for a minimum of two hours,
which is effective in treating the AGD, and
fish are then released back into the pen.
• We determine when the fish need to be
bathed by performing gill checks on our fish.
This occurs every 14-21 days. We track the
level of AGD infection which then allows us
to plan the bathing regime required.
• The number of bathes required is reducing
each year class of salmon, this is due to the
selective breeding program. Our brood stock
are selected for both AGD resistance and
growth traits.

10. Fresh water is sourced
from our reverse Omosis
Plants and pumped into
holding liners
The RO systems can service all of our
fresh water requirement .
Can produce more water than what
we require.
We can produce 3.5 meg in 24 hours
utilising both plants.
Holding four liners at Paddy’s Point,
two in operation two filling at one
time.
. 4 bathes per week on average over
Summer

11. Shoreline Clean Ups
• We take marine debris
seriously, and know that we
need to focus on this area
• Our primary focus is stopping
it at the source
• We perform regular shoreline
clean-ups in the areas we
operate
• We collect all rubbish found
• We have a partnership with
indigenous social enterprise
group Pakana who work for us
performing shoreline clean-
ups.
• We have completed four clean-
ups , since the last community
information session

12. • Clean-up event for the
month of October
• Cleaning up areas
Buckland to Bicheno
• Involving community,
organisations and
businesses
• All rubbish will be
sorted and categorised
at the end of the month
 After clean-up party
on the 3rd of November
at the East Coaster Resort.

13. Environmental
Monitoring
• Beach Surveys
• Water Quality Monitoring
• Benthic Surveys
(Broadscale/Compliance
and Control)
• Reef and Seagrass
Monitoring
• Modelling (Sediment
Dispersion and
Hydrodynamic)
• Video Compliance Surveys

18. Eco Aquaculture
• We are currently trialling seaweed on
our Okehampton, Port Arthur, Nubeena
and Dover leases
• Trialling three different species
Macrocystis, Lessonia and Ecklonia
species
• Macrocystis is proving to be the most
successful, this is the giant kelp species
in decline on the east coast of Tasmania.
• We are also involved in attempting to
re-establish kelp beds off the Tasman
Peninsula in conjunction with
Eaglehawk Dive Centre. The picture at
the top ‘is of a kelp plant grown from
seed in Pirates Bay of the Lufra. Planted
Nov16, picture taken Nov17.
• Trialling temperature tolerant species of
macrocystis, IMAS trials.

against its core community pillar (health &
wellbeing; environment; education and social
inclusion. We have support to date:

20. Transparency
• Tassal awarded in 2017 #2 in the world for
transparency of sustainability reporting. #1 in 2016
and #3 in 2015 (seafoodintel.com)
• Transparency brings scrutiny, however also drives
improvement
• Our new interactive site-by-site dashboard,
launched 2018
• Our new “Tassal Group” website has under-pen
footage taken via an ROV camera from our leases
• All interactive, 3D videos from our partnership with
Primary Education Industry Foundation Australia
(PIEFA) are available to view online via our “Tassal
Group” website or by downloading the FarmVR app
