Site Management Plan 2015

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.
