Various Canadian aquaculture associations issue joint statement on liberal policy

The Canadian Aquaculture Industry Alliance, together with its regional counterparts, BC Salmon Farmers Association, Ontario Aquaculture Association, Atlantic Canada Fish Farmers Association, Aquaculture Association of Nova Scotia and Newfoundland Aquaculture Industry Association, today issued the following joint statement:

The Liberal platform commitment to moving all salmon production in British Columbia to 'closed containment by 2025' is highly irresponsible with potentially serious and far-reaching negative consequences for Canadian jobs and the environment.
 

'This is a reckless policy, not grounded in science, and it will threaten good middle-class jobs across Canada,' says Timothy Kennedy, President & CEO of the Canadian Aquaculture Industry Alliance.

Salmon farming is the most environmentally sustainable large-scale farmed animal production in the world. It's a solution to climate change. British Columbia farm-raised salmon production has been recognised as being a global top sustainable performer, the Monterey Bay Aquarium's 'Seafood Watch' recognised the provincial production as 'a good alternative' last year, the only region so recognised in the world, and the FAIRR Global Index lists BC salmon producers as the top sustainable global producers of animal protein. It is a critical solution to the world's growing demand for low impact, low carbon emissions, high protein food supply while alleviating pressure on threatened wild fish stocks.

Seafood farming provides 26,000 full-time jobs across Canada. It generates $5.4 Billion in economic activity in Canada. Salmon farming makes up close to 90 percent of this economic value.  This is a young, highly innovative sector that is providing full-time jobs across Canada where these jobs are needed most: in indigenous, remote, and coastal communities.

The Liberal party has consistently said it will base decisions on science. There is no evidence that B.C. salmon farms are harming wild salmon populations. While pilot projects to grow salmon to full size in closed containment are happening around the world, this work needs to continue in partnership and without any artificial mandates and timelines.

No other nation has proposed this requirement of their salmon production. If implemented, this requirement will only move local, top-quality production to other countries that may not have the high environmental standards Canada already employs.

'While we are already a top global performer, our sector is committed to constant improvement. Our farmers need support and confidence to continue to invest in Canada. This irresponsible policy platform seriously undermines this confidence,' Mr Kennedy concluded.

The highs and lows of RAS

by Daniel Jackson, Content Editor, International Aquafeed

Aquaculture is a rapidly growing industry; it will soon overtake wild fisheries as our dominant source of seafood. One of its main advantages is that it is more sustainable and environmentally friendly than traditional fish farming, which has high feed requirements, water use, and makes a significant impact on the local environment by re-leasing effluents. This is a problem that could be solved by the use of intensive recirculating aquaculture systems.

Traditional saltwater aquaculture setups, in which fish are kept in tightly packed offshore pens, produce huge amounts of pollution. It is estimated to be equivalent to the raw sewage produced by a town of several thousand people, and it all flows directly into the ocean.
 

In a recirculating aquaculture system (RAS) waste products are either used for other purposes (as a fertiliser for plant life, for example) or processed so that it can be re-circulated. This saves money, resources and is better for the natural environment.

In a standard setup water would first be filtered to remove any solid material, then passed through a biofilter to convert ammonia (which is excreted by fish) into nitrate. After leaving the vessel holding fish the water is first treated for solids before entering a bio-filter to convert ammonia, before degassing and oxygenation, often followed by heating/cooling and sterilisation.

Each of these processes can be completed by using a variety of different methods and equipment, but regardless all must take place to ensure a healthy environment that maximises fish growth and health.

History
The earliest scientific research on RAS was conducted in Japan in the 1950’s. These early trials focused on biofilter design for carp production and were driven by the need to use limited water resources more productively.

At the same time European and American scientists attempted to adapt technology first developed for sewage treatment. Despite a strong belief by pioneers in the commercial viability of their work, most studies focused on science and the viability of the model in terms of chemistry. Furthermore, most of early trials were conducted in laboratories at very small scales.

As a result of these early mismanaged trials, many companies sold systems that were bound to fail resulting in scepticism amongst investors and delays in further technical improvement. Some simple but costly early problems were relatively easy to redress whilst others have proved more difficult.

Improving feed digestibility of low fishmeal diets

by Phileo Lesaffre

The continually increasing demand for fish farming is driving a shortage in fishmeal supply to the aquaculture industry. As a consequence, fishmeal prices are rapidly increasing and challenging the aquafeed industry to seek economically viable and environmentally sustainable alternatives to fishmeal and fish oil.

This quest for alternative ingredients, particularly protein sources, is of utmost importance, especially for supporting the shrimp aquaculture industry. Shrimp is already a heavily traded commodity and its production through intensive aquaculture is expected to continue to notably expand in the coming years.
 

Pitfalls of plant-based ingredients on feed digestibility
Plant-based ingredients are good candidates to partially replace fishmeal in aquafeeds because they are largely available, fairly economical, and provide a good and reliable source of protein. However, the inclusion of crop-based feedstuffs in shrimp feed is followed by numerous challenges such as reduced feed acceptability and digestibility.

Vegetable protein sources, like soy, sunflower, rapeseed, among others, show high content in fibres and include anti-nutritional factors (ANFs). ANFs are biological compounds that reduce nutrient utilisation and feed intake, and comprise molecules including proteinase inhibitors, saponins, and antivitamins alkaloids.

These compounds can be deleterious for shrimp growth as they inactivate digestive enzymes and decrease feed digestibility (Bora, 2014). Indeed, both high fibre content and ANFs negatively affect feed intake, FCR and, ultimately decrease shrimp growth performance.

A highly digestible feed additive to supplement low fishmeal diets
In order to address the limitations of replacing fishmeal with plant-based ingredients in shrimp feeds, Phileo Lesaffre developed the feed additive Prosaf® – a premium yeast fraction obtained from the primary culture of a proprietary Saccharomyces cerevisiae baker’s yeast strain.

The feed additive Prosaf is produced using a standardised process: after fermentation, yeasts are autolysed through thermal treatment, which is followed by a centrifugation step that separates the cell extract from the cell wall. The latter is discarded, and the inner cell wall fraction is isolated to be subsequently used as a premium and high-quality soluble product.

French seafood lovers can look forward to getting closer to nature with Salvea™

Global aquafeed supplier BioMar and French rainbow trout producer Aquadis Naturellement partner to bring farmed fish closer to end consumers. Aquadis Naturellement's rainbow trout fed with BioMar's Salvea™ feeds aim to provide consumers with what they are looking for - a natural and sustainable seafood choice.

An emerging consumer trend
The partnership takes its departure from an emerging trend in consumer behaviour. 'Today's seafood consumers are not only interested in what's on their plate, they also want to know where it comes from, how it is made and what is in it.' explains Ole Christensen, Vice President of EMEA Division at BioMar Group.

'With a lot of mixed messages in the market it can be confusing for the consumer to make a healthy choice and that is why many look for natural and organic foods. This is how the 'back to nature' trend has emerged,' Ole Christensen continues.

Jean-Pol Le Ribault, CEO of French trout producer Aquadis Naturellement, agreed, 'Consumers are concerned whether the food choices they make are good for their well-being and if it has been produced in a sustainable manner.'

'This development increases our responsibility as fish farmers for providing wholesome seafood which also respects nature and its resources,' Jean-Pol Le Ribault adds.

SalveaTM – a natural and sustainable choice
Salvea™, developed by BioMar, is a new feed concept based on two clearly defined pillars: 'closer to nature' and 'with a sustainable profile'.

'Getting back to nature does not only mean getting from nature. It also means giving back to nature. This is the fundamental idea behind Salvea™. With Salvea™ we aim to assist our customers in providing today's consumers with a natural and sustainable seafood choice,' explains Ole Christensen.

The first feed under the Salvea™ portfolio will be available for rainbow trout farmers in the French and Spanish market. The recipe has a natural characteristic as it contains naturally derived pigments, added natural antioxidants and ingredients that resemble natural prey for fish, such as insect meal. It also includes an increased level of the healthy Omega-3 fatty acids EPA and DHA, which have proven health benefits for both fish and humans.

Together with the inclusion of the above-mentioned insect meal, which replaces part of the fish meal, the Salvea™ recipe uses fish trimmings meal. This results in a FIFO* as low as 0.3, making it very sustainable.

'It is important to emphasise that Salvea™ is not only about individual raw materials, as these may change. Products under the concept may change, yet the basis of Salvea™ lies in a consumer demand, looking for a natural, healthy and sustainable lifestyle' Ole Christensen emphasises.

New GFLI entity to make environmental data on feed ingredients publicly available

Recognising that animal feed is a critical component in measuring the total environmental footprint of animal nutrition products, an international consortium came together in 2016 to establish a 'global gold standard' for calculating the life-cycle analysis (LCA) of feed ingredients.

Now, the founding partners of the Global Feed LCA Institute (GFLI) are establishing a legal non-profit institute, under the same name, to expand its work and make the data more widely available to stakeholders throughout the global food value chain.
 

An international consortium of feed industry partners came together Sept. 19 to establish the Global Feed LCA Institute, which will provide greater access to environmental data on feed ingredients so stakeholders can improve their accuracy for reporting the environmental impacts of sustainable animal protein production.

'Having access to reliable and scientific environmental data on feed ingredients is important for companies, academia and others working on sustainable animal protein production for not only improving the accuracy of their environmental reporting, but also for benchmarking and setting future sustainability goals,' the founding GFLI partners said.

The institute's mission will be to make publicly available an expanded regional and sectorial animal nutrition LCA database, consolidating the existing LCA datasets GFLI developed for the European Union, United States and Canada.

New and emerging mycotoxins analysed by Alltech 37+® Laboratory

New and emerging mycotoxins can now be analysed by the Alltech 37+® Laboratory. In total, five new mycotoxins have been added to the testing panel, bringing the total number of detectable mycotoxins to 54. These new additions further increase the understanding of mycotoxin occurrence and the potential risk to animal performance.

Emerging mycotoxins refers to mycotoxins that are neither routinely analysed nor legislatively regulated. However, research has shown more evidence of their increasing incidence and potential toxicity to animals. The emerging mycotoxins analysed by Alltech 37+ include beauvericin; moniliformin; enniatins A, A1, B and B1; phomopsin A and alternariol. Fusaric acid also features in this emerging mycotoxin category.

'The Alltech 37+ mycotoxin analysis test is the cornerstone of the Alltech Mycotoxin Management program,' explained Nick Adams, global director, Mycotoxin Management, Alltech. 'We now test for 54 mycotoxins. With this new analytical capability, Alltech is better equipped to understand how contaminated feedstuffs might impact animal performance and health.'

Due to their toxic properties, mycotoxins are a concern for livestock producers, as they can impact feed quality as well as animal health and performance. A world leader in mycotoxin management, Alltech's 37+ test results provide a realistic picture of mycotoxin contamination in feed ingredients or total mixed rations, speeding up the process of diagnosis, and suggest effective remediation and help move toward an effective mycotoxin control plan.

'Since adding these mycotoxins to our analytical capabilities, we have already seen a high frequency of samples with these contaminants,' explained Dr Patrick Ward, Ireland Analytical Services Laboratory manager, Alltech. 'As we test more samples and accumulate more data, we will strengthen our understanding of these mycotoxins.'

Between Alltech's 37+ mycotoxin analytical services laboratories in Lexington, Kentucky, and Dunboyne, Ireland, they have run over 30,000 samples, each searching for up to 54 mycotoxins in animal feed.

Study finds krill an effective growth enhancer for whiteleg shrimp

With the shrimp farming industry increasingly moving towards low fishmeal content feeds, practical feed formulations depend on meals, solubles and hydrolysates made from fish, squid, shrimp, krill and molluscs to act as chemoattractants and feeding stimulants. But with such a wide array of options, identifying the optimal marine chemoattractant for a species like whiteleg shrimp has proven incredibly difficult, until now. 

Antarctic Krill

Published in the peer reviewed Journal of the World Aquaculture Society, a new study conducted by a team from the Instituto de Ciências do Mar, Brazil (Labomar) in conjunction with Aker BioMarine, has suggested a winner in krill meal.
Assessing the feed preference and the growth response of juvenile whiteleg shrimp (Litopenaeus vannamei) to various different marine chemoattractants, a diet with three percent fishmeal was supplemented with either three percent krill meal, squid meal, shrimp head meal, shrimp meal, squid liver meal, salmon meal, soy protein concentrate or five percent liquid sardine hydrolysate.
With under 100 animals/m2 in 56 1-m3 tanks, shrimp were fed 10 times daily for 74 days. At harvest, the shrimp were counted, weighed, and their growth performance and feed efficiency determined. In order to evaluate feed preference, two-by-two comparisons were carried out, with diets with different chemoattractants delivered simultaneously in two separate feeding trays allocated in each tank.

New era beckons for Scottish Sea Farms and its long-standing Production Director, John Rea

Scottish Sea Farms' long-standing Production Director John Rea is to step down in early 2020 to take his career in a new direction, the company has announced.

Following 22 years in the role, an instrumental aspect of which has been nurturing and mentoring the marine farm team, Mr Rea plans to take his passion for personal development and coaching to the next level by establishing his own private practice.

The career move comes on the back of John having achieved an accredited qualification in the specialism.
 

Scottish Sea Farms' Production Director, John Rea

Scottish Sea Farms' Managing Director Jim Gallagher said, 'On a professional level, I'm hugely sorry to see John go. We both joined what was then Hydro Seafood within months of each another and soon found ourselves overseeing the company's sale. In the years since, we've grown Scottish Sea Farms into one of the country's leading growers of premium salmon, making it our shared mission to farm as responsibly and sustainably as possible.

'On a personal level, as both a long-standing colleague and good friend, I wish John every success with his new career. His ability to motivate and inspire all who work with him is renowned throughout the company, so this new career move feels like the natural next step, enabling John to share his skills with a wider audience.'

Hailing originally from Northern Ireland, John moved to Scotland in 1997, leaving Hydro Seafood Fanad in County Donegal to take up the role of Biologist with Hydro Seafood GSP.

In 2001, Hydro Seafood sold its Scottish farms to Norskott Havbruk, which operates as Scottish Sea Farms, with Mr Rea being appointed Production Director in 2002.

John will remain in the role and continue to be responsible for all marine farming activities until his successor is appointed.

Mr Gallagher added, 'Our aim is to set the benchmark for sustainable salmon farming and we're looking for a forward thinking, sector experienced, commercially aware candidate who can build on the gains already being made in the key areas of fish welfare, environmental protection and product quality, and help accelerate our progress.

'John leaves big shoes to fill, however for the right candidate with the right combination of experience and drive this promises to be a truly career-defining opportunity.'

The deadline for applications is Friday 11 October more details, HERE.

Animal feed producer ups uniformity, cuts cycle times with fluidised bed mixing

by Steve Knauth, Marketing Manager, Munson Machinery Co Inc, Canada
Country Junction Feeds has produced animal feed products in Alberta, Canada for over 100 years. Today, it offers a full line of organic wet and dry feeds for cattle, hogs, poultry, horses, bison, elk, goats and sheep. To improve batch consistency and prevent damage when adding liquids to fragile ingredients, the company installed a fluidised-bed type mixer on its “wet feed" production line.
 

Dry feed in raw or pelletised form is typically pre-blended in a 2000kg capacity mixer. The wet blending process adds oils and/or molasses to rolled oats, barley, pellets and “bull ration” calf feed for nutrition and palatability as well as dust control.

To blend dry ingredients with liquid additions in batches of up to 300kg, the company installed a Munson model MF-18-SS fluidised bed mixer.

"Fluidised bed mixing brought more batch-to-batch consistency than the previous auger mixer," explains Mark Shantz, Country Junction’s Maintenance Manager, adding that it imparts less shear than the auger mixer, reducing product degradation, particularly with fragile materials.

How liquid additions are mixed with dry blends
To initiate a mixing cycle, an operator enters a pre-programmed recipe at a plant workstation. Individual ingredients, stored in outdoor granaries, are transported by chain drag conveyors to the aforementioned dry mixer for pre-blending.

Blended batches discharged into bins are then conveyed by either of two drag chain conveyors to the fluidised bed mixer. Load cells supporting the mixer transmit weight gain information to a PLC, which stops the conveyor once the preset batch weight has been gained, with +/- 1kg accuracy.

Once mixing begins, a fluid volume of oil or molasses equivalent to 3-to-10 percent of the dry premix weight is automatically metered from a 20kg capacity vessel and gravity discharged into the top centre intake of the fluidised bed mixer.

Zinc and omega-3 fatty acids

by Neil Auchterlonie, Technical Director, IFFO

Researchers from Nofima, the Norwegian research organisation, reported last month that the barrier tissue of salmon is affected by zinc and omega-3 levels in feed, in a recent piece of scientific work that was funded by the Norwegian Seafood Research Fund (FHF).

Why is this important? Well, the integrity of salmon skin, intestine and gill tissues is vital for the health of the fish. These barriers are recognised as important first lines of defence against pathogens, as well as being important in helping the organism handle physical stressors such as fluctuations in temperature, salinity, or water quality in general.
 

The article that has been presented on the Nofima website points out the importance of these compounds nutritionally, and particularly in relation to the changes we are seeing in feed formulations such as new feeds specifically for recirculation systems, as well as the obvious dominance of plant-based raw materials in modern feed formulations.

The research set out to investigate whether changes in feed composition would affect the health and robustness of farmed salmon, and the scientists looked specifically at the interaction of zinc and marine source omega-3 fatty acids in feed, for parr to post-smolt in recirculation systems.

It seems to be a part of an ongoing programme of work that has looked at the general robustness of fish in the aquaculture environment, which is highly applied and very relevant work. The results are described in the context of the health and welfare of the fish, and those are obvious impacts related to the ability of the salmon to cope with a pathogen challenge, whether it is ISA virus or sea lice.

This science is important in the context of declining marine ingredient inclusions in aquafeeds. Fishmeal and fish oil are excellent sources of many micronutrients, and among the many different compounds present that contribute to fish (and consumer) health are zinc and the long chain fatty acids, EPA and DHA.

The potential value of blockchain technology in the seafood supply chain

by Bryan Horsu, Master Student at the University of Applied Sciences, the Netherlands, Wesley Malcorps, PhD Student at the Institute of Aquaculture, University of Stirling, UK, Paul van der Heijden, Founder at MatureDevelopment BV, the Netherlands

A growing population with an increasing appetite for highly nutritious seafood resulted in an increase in global fish consumption from 9.96kg in 1961 until 19.86kg in 2013 (FAO, 2018). Capture fisheries and aquaculture are important contributors to fulfill the growing global demand for seafood (Food and Agriculture Organisation, 2018).
However, both industries are made up of complex global supply chains and are subjected to social and environmental challenges. Increasing consumer awareness and food safety requires increasing traceability and transparency along these supply chains.
 

This article explores briefly how distributed ledger technology, such as blockchain, could increase the traceability and transparency of the seafood industry.

It starts with a brief explanation of the potential of this technology in the aquaculture sector, in particular the aquafeed sector. Secondly, it will zoom in on the capture fishery sector through a conducted survey at a fishing company in the Netherlands.

Aquaculture, aquafeed and complex global supply chains
Capture fisheries have been close to their production limits and, as a result, the aquaculture industry is growing faster than any other food-producing sector. Large amounts of aquafeed are required in order to sustain this growth rate in the coming decades.

Most life cycle assessments (LCAs) suggest that aquafeed accounts for most of the environmental impact of fed aquaculture production (Little et al., 2018). However, this impact is variable depending on the type and source of the feed ingredients.

Therefore, improved traceability and transparency along the supply chain could provide more accurate insight in the environmental performance and could highlight sustainability issues.
