Antibiotics

Salmon Health

Grams per tonne of fish

Data as of 30 September 2014

We take animal welfare very seriously at Huon so we go to great lengths to ensure our salmon live a low stress, healthy and happy life. Huon even has a full time veterinarian on staff to ensure the health and welfare of our fish is second to none. He consults and works with our farm staff every day to monitor the health of our fish and continually improve practices.

Sometimes, just like people, our salmon get sick. If our vet feels there is a need to treat the fish with antibiotics for an illness you can rest assured that it is supervised, reported, strictly regulated by government, and that the antibiotics are allowed to pass through the fish long before it is harvested in accordance with regulatory requirements.

At the same time we are taking a proactive approach to creating vaccines and diet regimes that allow our fish to combat known illnesses and lead healthy and happy lives.

Antibiotics were used at the beginning of 2014 as four pens containing smolt were confirmed with an rickettsia-like organism infection and were treated shortly after transfer to sea in late summer. The treatment was effective and no other pens were effected and therefore did not require the treatment.

Dissolved Oxygen

Growing Conditions

Salmon need a good supply of oxygen to keep their metabolism fuelled. Having clean nets and good water flow on our lease sites is important. Ideally a minimum dissolved oxygen level of above 6.5 mg/l will ensure our fish are happy and stress free.

*Measurements shown are a monthly average of readings taken at 0, 3 and 5 metres. Where environmental conditions are less than ideal, we use every tool at our disposal to minimise the stress on our fish.

 

Water Temperature

14° Growing Conditions

Tasmania is the only place in Australia where the water temperature is ideal for growing salmon. We ensure we manage how many fish we hold in each net to ensure that they are always comfortable, well fed and enjoying the pristine conditions on our farms.

*Measurements shown are a monthly average of readings taken at 0, 3 and 5 metres. The ideal water temperature range for our salmon is between 12-15 degrees Celsius.

Where environmental conditions are less than ideal, we use every tool at our disposal to minimise the stress on our fish.

 

Seal Interactions

Number & Entries

Like all farming operations we must operate in harmony with the environment and the other animals that call it home. As fish farmers in Tasmania our biggest challenge is living with seals. They are big (up to 450kg), smart and they seem to love salmon.

Data as of 30 September 2014

Year Sightings Entries Accidental Deaths Euthanised Percentage of total population
2012 8168 1116 12 2 0.014% (14)
2013 11650 712 13 1 0.014% (14)
2014* 8068 219 8 0 0.008% (8)

*Results to September 2014.

Total seal population is approx 100,000 - source DPIPWE.

Accidental deaths can be anything from a seal getting trapped in one of our nets whilst trying to breach a pen or simply a seal that is dying within our lease space.

Our absolute last resort with persistent offenders (repeated entries into pens and representing a danger to our employees through aggressive behaviour) is to apply for them to be humanely put down. This is only ever done by a veterinarian and Parks and Wildlife strictly supervise and document the procedure.

 

Feed

Fish Meal & Fish Oil

The diets we feed our fish have to meet some special requirements and deliver in two main areas; firstly they need to provide the fish with enough energy to live and thrive; secondly they must supply all the nutrients (proteins, fats, vitamins and minerals) to grow.

Data as of 30 April 2014

Fish Meal and Fish Oil Use

Fish Meal Fish Oil

*per kilogram of fish produced

Our salmon need to eat a certain amount of fish meal and oil to ensure they are healthy and remain a good source of Omega 3. Fish meal and oil is extracted from fast growing oceanic fish like anchovies, these are classed as “forage fish”. Each of our salmon last year needed the equivalent of 1.69kg of forage fish as fish oil for every kilogram of weight it grows, the forage fish caught for fish oil also provided all of the fish meal our salmon needed (equivalent to 1.18kg of those forage fish). To put this use of marine resources in context, a wild salmon will eat 10 kilograms of forage fish to obtain its protein and oil for every kilogram it grows.

We have recently changed the method by which we measure the amount of fish meal and oil used per kilogram of fish produced. Our reporting is now in line with Aquaculture Stewardship Council (ASC) standards, which is acknowledged as the future for global standards in sustainability and environmental standards. Huon is committed to achieving best practice across all these areas of its operations and we are proud to be compliant in 2013 for standards in both fish meal and fish oil.

New Pen Rollout

Our new seal and bird-proof pens are being rolled out across our farms in Southern Tasmania right now and we expect the rollout to be completed in 2015.
