Site Management Plan 2015

Page 2

1 Input Water

Input water is transported to site from the mouth of the Noosa River by truck. The water is
pumped into our 22500ltr water storage tank where it is mixed with freshwater from the town
supply. This is done to reduce the salinity of the water. The water is treated using liquid
chlorine at a concentration of 5ppm for a 24hr period. The chlorine is removed by adding
Sodium Thiosulphate. When water is required to top up the system the water is pumped
through UV for backup disinfection and oxidisation of any residual chlorine.

2 Food storage

The fish food is stored to manufacturer’s requirements. It is stored in a room that is rodent
proof and regularly treated for pests. The food is stored on pallets to keep it off the floor and
allow air to circulate around the food bags.

3 Chemical use

a) Ensure all personnel are aware of the hazards of the chemicals used, and that they have
training on the storage, use and handling of the chemicals used and are provided with
appropriate protection gear to the chemical. This will be clearly stated at the staff induction
process.
b) Comply with the regulations on the use of chemicals in aquaculture. Be aware of the
chemicals registered for use in aquaculture and the need to consult a registered vet. No
antibiotics or feeds containing antibiotics are to be used whatsoever – you must consult a
vet. If you use anything that is not registered or prescribed you will be in breach of the
legislation. Controls over the supply and use of Agvet chemicals in Queensland are provided
for in legislation, in particular the Agricultural and Veterinary Chemical (Queensland) Act
1994 (Agvet Code), the Chemical Usage (Agricultural and Veterinary) Control Act 1988
(Chemical Usage Act), Agricultural Chemicals

     Distribution Control Act 1966 and The Health (Drugs and Poisons) Regulation 1996
        (What Veterinary Surgeons Need to Know).



4 Mortality Disposal

Any fish mortalities will be recorded and stored in the onsite freezer until the council rubbish
day when they will be removed from the freezer and placed in the council bins to be disposed
of correctly. If we have a large mortality event the dead fish will be loaded into our utility
which will be lined with plastic and taken to the Local Noosa landfill site.

5 Bio Security

Foot baths and hand washing facilities will be placed at both of the entries to the juvenile and
grow out system. Foot baths and hand washing facilities will be available at the entrance to
the quarantine system.

If the facility is to be managed by 1 person at any time, the grow out facility then juvenile
system must be maintained before entering the quarantine system. If it is required to go back
into the grow out or juvenile system then the employee must change into clean clothes and
put dirty clothes into laundry baskets supplied. The employee must wash themselves down
with disinfectant wash shoes in foot bath and then enter the facility.

Page 3

Water is never to be swapped between systems and discharged; water from quarantine
system must be discarded into approved waste disposal system. Water can be moved
between juvenile and grow out if there are no signs of disease in either part of the facility.

All employees are to stay away from trucks bringing in replacement water and at no time are
water truck drivers allowed inside the facility.

When loading market sized fish into transport trucks the fish must be taken outside to be
loaded and then the vessels containing the fish are to be washed with chlorine and left in the
sun for 24hrs before bringing back into the facility. at no time are the delivery drivers allowed
into facility.

6 Waste Management.

Rubbish bins are to be provided and included in our maintenance programme will be a daily
pick up of any rubbish to avoid effecting the surrounding environment and interfering with
operations of our equipment involved in the running of our RAS. The bin areas will be not be
in any near proximity to the operating system.

7 Waste Water Management

All water to be discharged will be pumped into our 22500ltr waste storage tank where it will
be dosed into the council sewer at a maximum rate of 7l/m to stay under our 10000ltr / day
discharge allowance. A u-trap will be placed in the discharge pipe with a tap so samples of
the waste water can be taken by any regulatory government departments. The waste water
flow rate and salinity will be monitored by inline sensors and the data logged by our
computers and remotely by unity water.

8 Feeding Regimes

Our feeding regime will include the use of multiple feeding times throughout the day and at
different times for each system. This will provide a more consistent nutrient load on the
system which will allow us to keep water quality at ideal levels and after being processed by
our denitrification system allow us to discharge water of consistent and lower Nitrate loads.

9 Fish escape prevention

Our intension was to screen the outflow from the facility to the waste storage tank. The
viscosity of this waste will be too low to flow through screens without constant, serious
fowling which will add a large amount of labour cost to keep operational. The waste will go
into the storage tank and be in there for up to 48 hours. Any escape fish or larvae that enter
this anoxic environment would not survive anymore that a few minutes therefore it would be
impossible for fish or larvae to escape this way. Our RAS being a closed system does not
allow the escape of fish and as discussed if fish do enter the waste tank they will be dead
within a few minutes and the bodies would most likely be consumed by the bacteria that will
colonise this storage tank.

10 Site Environmental Impact

Having extensive experience with RAS in the past we have created detailed management
practices for both onsite and offsite to prevent any impact on the surrounding environment.
Being a closed system we are able to closely monitor the environment the fish live in so
when a problem is foreseen by our monitoring system and testing practices we can put our
management practices into action to prevent any water quality issues before they affect the
environment the fish live in.

Our surrounding environment is protected by close monitoring of out discharge water which
allows us to control the quantity and quality of the waste being discharged. Our waste
management practices allows us to keep any possible contaminates contained within our
concrete lined facility where it can be dealt with quickly and safely.
