By purchasing our Atlantic Salmon and Ocean Trout you are:

Caring about animal welfare
Petuna produces Atlantic Salmon and Ocean Trout at a low pen density, so that they have room to move and are therefore healthy and stress-free. Even with the best care, fish may still become susceptible to disease. Ethically we must treat our fish as you would treat yourself or a family member if they were suffering from an illness.

Reducing food miles
68% of our fish feed ingredients are sourced from within Australia and the majority of Atlantic Salmon is sold within Australia.

Choosing a natural product – no genetic engineering
Our Australian feed companies maintain a GMO-free status. Since January 2000, in accordance with Australian regulation (Food Standards Australia New Zealand Code), Australia has maintained a ‘GMO DNA-free’ status of aquaculture feeds. Our vegetable raw materials are purchased as non-GMO and supplier certifications are documented.

Tasmania has a no GMO policy: Click here to view

Saying no to labour exploitation
Our employment policy bans forced or bonded labour and adheres to the existing International Labour Organization conventions and standards.

Supporting wild fish conservation
We choose feed suppliers that take responsibility for wild fish conservation by purchasing fishmeal and fish oil that is certified International Fishmeal and Fish Oil and Organisation Responsible Sourcing (IFFO RS) or Marine Stewardship Council (MSC).

Reducing packaging
Petuna is a signatory to, and supporter of, the Australian Packaging Covenant. The Covenant is the voluntary component of a co-regulatory arrangement for managing the environmental impacts of consumer packaging in Australia. The Covenant is designed to minimise the environmental impacts from the disposal of used packaging, conserve resources through better design and production processes, and facilitate the reuse and recycling of used packaging materials.

The Marine Environment

THE MARINE ENVIRONMENT

We make sure the environment in which we raise our fish is kept healthy, including the seabed and the local marine areas

As custodians of the marine environment in which we produce our Atlantic salmon and ocean trout, we consider the health of these waters as paramount. We have management strategies in place to protect the seabed under pens and ensure minimal impact. Fallow periods allow the benthic environment to return to its natural state and continuous water quality monitoring ensures our fish and the marine species that share this water space all thrive in a healthy marine environment.

The behaviour of Atlantic salmon and ocean trout changes in response to the condition of the marine environment and to ensure optimum environmental parameters the marine ecosystem is constantly monitored. The benefits of measuring environmental conditions like the seabed and water quality are two-fold: it prevents unwanted impacts on the marine environment and at the same time maintains the good health of our salmon and trout. To prevent impacts on the marine environment and on the health of our fish, our operations are monitored in two ways:

  • we continuously monitor oxygen levels on our leases and individual pens during feeding, and we monitor water temperature, salinity and algae on a daily basis; and
  • government-regulated monitoring to measure compliance.

Monitoring to maintain optimal environmental conditions, coupled with our farm fallowing programme, means that the marine plants and animals that share the environment can process the nutrient inputs more efficiently. Similarly, our low pen stocking densities mean that oxygen in the seabed can break down nutrients rapidly and can easily deal with organic inputs from our farm operations. We operate within the requirements of the Marine Farming Planning Act 1995 and the Living Marine Resources Management Act 1995. Click here to find out more:

Our Atlantic salmon and ocean trout are fed a diet composed of a range of ingredients formulated to provide our fish with all the correct nutrients in the form of protein, fat, carbohydrate, and vitamins and minerals. A nutritionally balanced diet is essential for healthy growth and supporting a strong immune system.

The diets we feed our fish are specifically formulated for the various stages of their life cycle. Just as a human’s nutritional requirements change as we grow from an infant to an adult, so too do the requirements of our fish change as they develop.

‘Ensuring we use feeds that have been responsibly produced’

As a responsible Atlantic salmon and ocean trout producer, one of our aims is to raise healthy fish rich in omega-3s by feeding them with responsibly produced fish feed. Our industry depends on global natural resources to produce ingredients for fish feed. Our use of fishmeal and fish oil sourced from small pelagic fisheries is one of the most commonly discussed topics in aquaculture. By limiting the amount of fishmeal and fish oil in our feeds sourced from reduction fisheries, such as anchovy, we are less reliant on this one resource, which helps to reduce the pressure on these fish stocks. Fish trimmings by-product are another source of fishmeal used in our feeds. Trimmings are parts of a fish that are not used for human consumption and would otherwise be wasted. Essentially, these trimmings are being recycled and used to feed and grow our fish.

To measure how efficient we are at conserving fishmeal and fish oil in our feeds, we apply what’s called a ‘fish in fish out’ (FIFO) ratio. This ratio indicates the amount of marine ingredients from reduction fisheries (kg) that are required to grow an equivalent weight (kg) of Atlantic salmon or ocean trout.

For example, if 1kg of marine ingredients from a reduction fishery is used to grow 1kg of Atlantic salmon, then the FIFO ratio would be 1:1 (1kg/1kg). The lower the ratio, the less fishmeal and fish oil is used.

At Petuna we apply techniques that constantly aim to improve our FIFO ratio. Within the company we invest in the best in-pen monitoring systems and apply on-farm feed management practices to ensure that all feed we give to the fish is eaten and turned into growth so eliminating waste. We also seek support externally, working closely with our feed suppliers to reduce the level of fishmeal and fish oil in our feeds. Each year we are conserving more fishmeal and fish oil and improving on feed efficiency as we continue to strive for a more sustainable production of Atlantic salmon and ocean trout.

At Petuna, we follow the FIFO method stipulated by Best Aquaculture Practices (BAP). This socially and environmentally focused standard is considered the world’s strictest independent aquaculture standard. At Petuna we are leaders in best practice, using 1.4kg of wild-caught fish to produce 1kg of Atlantic salmon and 1kg of ocean trout, and our aim is to continue reducing the amount of wild-caught fish in our feed.

Petuna is committed to working with our fish feed suppliers to continue to reduce pressure on stocks of wild fish and we are proud to source feed from companies that are working hard to do this. We are also committed to continuously improving our feed management practices to improve our feed efficiencies.

Fish Welfare

Fish Welfare

Fish health and welfare is at the heart of all that we do

We have a dedicated team of fish health professionals who provide the best care for our fish in both the marine and freshwater environments. We meet Best Aquaculture Practices (BAP) and Aquaculture Stewardship Council (ASC) animal welfare requirements for farmed Atlantic salmon and Ocean Trout.

Pen density – room to move
We have some of the lowest stocking densities in the world which means our fish have plenty of space to swim around. In fact, Petuna’s stocking density is 15kg per cubic metre which is significantly lower than the level that is currently considered global best practice. The natural behaviour of salmon is to school as they swim together and our aim is to promote a clean environment and natural behaviour. This in turn ensures:

  • healthy, stress-free salmon and trout
  • optimal growth
  • enhanced environmental conditions due to a reduction in organic enrichment from feed and fish faeces underneath the pens
  • more available oxygen for our fish and the marine environment

Ensuring our fish remain healthy
Ethically we must treat our fish as you would treat yourself or a family member if they were suffering from an illness. On the rare occasion we may need to treat unwell fish, it is done so under the supervision of a qualified veterinarian and strict government guidelines. You are guaranteed that Petuna Atlantic salmon and ocean trout contain no antibiotics or chemical therapeutants when sent to market.

Estimated unexplained loss of fish (EUL)
Some circumstances where it’s possible to lose fish include predation, disease, and stress from suboptimal environmental conditions; however, we have procedures in place to prevent these types of fish loss. It is possible to lose fish for unexplained reasons; these are usually the result of fish escaping and/or counting inaccuracies. To validate our counting accuracy (number of fish in the water) we calculate unexplained fish loss. If our estimated unexplained loss of fish is greater than ±2% due to a counting error then the auditor will investigate further as losses above this margin of error may indicate escapes and mortalities that have not been accounted for. We calculate the EUL at the end of each production cycle. The EUL for Macquarie Harbour 2015 production is 1.9% for ocean trout and -5.1% for Atlantic salmon, for our lease which has 2016 salmon it is -5.18. Our Long Reach site Atlantic salmon is an EUL of -9.8%.

Treatments
We have not treated our Macquarie Harbour fish with antibiotics since October 2014 and at Long Reach the last time we treated fish was August 2014.

Petuna’s main strategy for minimising wildlife interactions is based on implementing passive measures. We prefer not to use any acoustic deterrents to manage wildlife, instead relying on our skilled marine operations staff and robust net-pen infrastructure and large bird-net apertures to keep wildlife safely outside our pens.

Wildlife interactions are diligently logged by our staff and we are required by law to report these interactions to Department of Primary Industries, Parks, Water and Environment (DPIPWE). At Petuna we are continually looking to improve our processes that minimise wildlife interactions.
