24/11/2017: Salmon and trout producers unite against key barrier to sector growth

Scotland’s leading salmon and trout producers have united in a bid to extend the usage and efficacy of the two most environmentally-friendly sea lice treatments

Currently, two possible ways of treating farmed Atlantic salmon against sea lice – a key barrier to sector growth – are to bathe the fish either in freshwater or hydrogen peroxide which quickly breaks down into water and oxygen.

Now, in a project being co-funded by the Scottish Aquaculture Innovation Centre (SAIC), Marine Harvest Scotland and Dawnfresh Seafoods have teamed up with Solvay Interox, Aqua Pharma and academics at the University of Stirling’s Institute of Aquaculture to determine what happens when freshwater and hydrogen peroxide-based treatment Paramove® are combined.

Richard Hopewell, Fish Health Manager for Dawnfresh Seafoods and lead industry partner said, “This is early stage, investigative work being conducted within controlled tanks at the Marine Environmental Research Laboratory, part of the University of Stirling's Institute of Aquaculture, based at Machrihanish. There, we hope to confirm the efficacy of using freshwater and Paramove® in conjunction with one another, and, in doing so, contribute to the ongoing efforts of the industry in sea lice control.”

The anticipated benefits of the 12-month, £242,985 project include even better control of sea lice, reduced use of medicines and shorter treatment times – all of which will further enhance fish health and welfare, and help deliver higher production volumes.

SAIC CEO Heather Jones commented, “This project has the potential to be particularly ground-breaking. Not only does it see salmon and trout producers unite against a key challenge, but if it succeeds in delivering a more effective sea lice control using available, environmentally-friendly resources then the entire sector stands to make huge commercial gains in the drive to grow Scotland’s market share.”

It’s thought that the applied research project could lead to further collaboration between salmon and trout producers to establish the therapeutic value of other approved sea lice treatments at low salinities.

24/11/2017: A bright future for New Zealand aquaculture

by Peter Parker, International Aquafeed magazine

The 2017 New Zealand Aquaculture Conference was held September 20-21, at the Rutherford Hotel in sunny Nelson, a city on the northern coast of New Zealand’s South Island

The two-day event is held annually and brings together the nation’s aquaculture industry as well as exhibitors and international delegates. Featuring the Cargill EWOS sponsored technical day on the Wednesday, and the New Zealand Aquaculture conference on the Thursday, this event was the perfect opportunity for the industry to network and share ideas towards building a strong and sustainable aquaculture industry for the future. Throughout the event participants were discussing the excellent Sanford sponsored cocktail function which certainly lived up to the hype on the closing hours of the event.

According to Aquaculture New Zealand, the conference’s inspiring speakers, amazing seafood and unparalleled networking opportunities, has it “widely celebrated as New Zealand’s best primary sector conference.”

It is most fitting that Nelson is the scene for this conference, aside from being a beautiful place with great facilities for catering to visitors, it is also one of New Zealand’s key aquacultural hubs with a number of the key aquaculture support organisations being based there; such as Aquaculture New Zealand, the Cawthrone institute, and the Nelson Marlborough Institute of Technology.

The Aquaculture New Zealand organisation was formed in 2007 to be the single voice for the New Zealand aquaculture sector. Where previously, the New Zealand industry was made up of three independent species bodies in the New Zealand Mussel Industry Council, the New Zealand Salmon Famers Association and the New Zealand Oyster Industry Association. Aquaculture New Zealand aims to bring together these memberships.

According to the Aquaculture New Zealand website they are primarily funded through an industry levy, and their chief role is the implementation of the industry strategy which aims to grow the sector to earn NZD$1 billion annually by 2025. A value which was frequently mentioned throughout the conference with passion and optimism.

While in Nelson I was fortunate enough to be taken on a tour through the Cawthrone Institute’s aquaculture park by Dr Leo Zamora an aquaculture scientist currently conducting research on geoduck, a large edible clam with potential to be farmed in New Zealand. This was one of many species being studied at the 20 hectare aquaculture park that is equipped with purpose built wet laboratories, intensive algae culture facilities, dry laboratories, and more. The park which was formally opened in February 2011 is protected by Nelson’s boulder bank and is the ideal location for aquaculture research, development and commercialisation.

Cargill EWOS Technical day

Day one saw attendees receive a welcome from Aquaculture New Zealand’s Technical Director Colin Johnston. This was followed by a full on day of 20 presentations across two halls, the majority of which divided into the salmon stream and the diversification & resilience stream.

The presentations covered a wide ranging scope, with an opening plenary featuring Global Aquaculture Alliance’s President Dr George Chamberlain discussing aquaculture’s number one issue globally – biosecurity, sharing with the audience his experiences internationally with biosecurity.

The second plenary speaker was Associate Professor Christopher Burt on strategies to improve employee safety, highlighting the ever present problem across industries that is new employees’ safety and how to address this.

Topics were discussed throughout the day by University professors, research institute scientists, and industry representatives, ranging from ocean acidification, the potential of seaweed, right through to anti-microbial coating and surface additive solutions for the processing stage.

Attendees I spoke to said they had especially enjoyed a block dedicated to research and development, a topic especially relevant to the relatively young industry of aquaculture where innovation is both commonplace and necessary.

David Koedyk of Baldwins Law Limited gave a presentation and answered the audiences in detail on the intricacies of intellectual property law and the processes businesses should aim for. This was followed by presentations on the supply chain, the importance of pre-competitive R&D, and a panel discussion.

The day was closed with the New Zealand Salmon Farmers Association meeting for members and invited guests.

23/11/2017: Operating freshwater salmon RAS

by Ben Green, MA (Cantab), CEO, The Supreme Salmon Co., UK

Operating a RAS is quite a daunting task; the salmon are like astronauts of life support

I haven’t had a disaster for over a decade thanks to robust design, backup systems and a good alarm, but I still can never be quite sure what I will find in the morning. In this, the last of my three articles, I’ll describe how to run a RAS in the best way possible.

A lot of effort goes into the design and building of the unit but that’s just the start, there’s the smooth running of the system with a proper maintenance schedule and crucially, the care of the stock.

I can’t say I’ve read a huge amount about fish rearing but I can’t ever recall seeing an article devoted to the wellbeing and behaviour of the fish reared and how crucially important it is to for the smooth running of a RAS unit. Carp are very tolerant of bad environments and are easily domesticated but salmon are like racehorses and will take every opportunity to die that is offered.


I would imagine most people know about pH, ammonia, nitrites etc. levels so I won’t dwell on this for very long assuming the system is up to the job. I don’t monitor these anymore unless there might be a problem, my systems have a large cushioning water volume and I keep the bio-filter alive between crops.

A bio-filter should be coping with ammonia after a day or two; the nitrites can take up to a month to stabilise and in three months the filter is fully mature. A RAS is home to two animals, the fish and the filter, if one dies then the other dies with it.

For this reason it’s very dangerous to have anything around that might accidentally kill either, chemicals like Chloramine T destroy filters instantly and the fish will die soon after if there isn’t enough fresh water to call on. The filter can grow with the fish if a batch policy is operated, a continuously harvested system has a stable biomass but is probably always running near its maximum capacity like fully laden truck going top speed all the time, good for efficiency but more likely to crash.

I use a batch process with discreet units and harvest over a period of time; this gives my static filters a rundown phase in which to clean themselves. Once the RAS is running it settles down to a life of its own, the operator will get used to the flow rates of the water and the sounds of the machinery.

These things can be noticed from day to day. A single operator will notice any slight changes that are a precursor to an equipment failure such as a noisy bearing on a pump, which can then be replaced in good time.

I look after my RAS 365 days a year (which is probably a bit sad!) but I have sole responsibility and no one else to blame if warning signs are not heeded, I can’t see how this can work so well with multiple personnel. A tip here, don’t change anything on the RAS then leave it!

It’s after an equipment change that something can fail, for example a pipe might not have been properly secured after a pump change, and will come off a few minutes later. There will still be some natural variation of water parameters over time; temperature varies with the seasons and with it an evolution of the filter flora and fauna causing changes in water clarity or oxygen levels.

This doesn’t seem to bother the fish but it can have implications for the smooth running of the system. For example if the water goes cloudy, the mortalities can’t be seen to be removed if they are normally visually speared or scoop netted, a rotting dead salmon in an RAS will cause chronic health problems in the rest of the stock.

It’s not always the case that addition of fresh water will help the system, I find I have the urge to add more borehole water ‘because it must do some good’ but this isn’t necessarily the case.

If the temperature is right and the fish are happy changing the water conditions will actually disturb them, spring or borehole water might look wonderfully clean to us but it’s often not a very good environment for fish in its raw form.
