Thank you once more for the commitment of all partners to the project, along with the willingness to share concepts, ideas, results, in order to ensure the achievement of our ambitious main GAIN objective of Aquaculture Eco-Intensification.
Waister has developed an innovative method for mortalities drying in aquaculture. This method is a substitute for ensilage, which is the most common way of treating mortalities today.
By using a Waister 15 drying machine, mortalities disposal may be reduced by 85 % compared to ensilage. This is achieved without adding formic acid. In this way, the method represents a substantial improvement for employees’ safety by elimination of hazards related to application of formic acid.
Waister has used the method on fish from the smallest fish of a few grams up to 4.5 kg. It works well on all kinds of fish – and has even been applied to salmon and trout with high fat content. For these fish species an additive, being wood chips or dried spent grain, is used to ensure a stable processing.
The development and verification of the method has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement N° 773330.
The official market launch of Waister 15 for mortalities happened at Aqua-Nor in Trondheim August 2021.

GAIN Summer School: Online, August 30th-September 3rd
The GAIN journey is nearly over and we would like to share results and lessons learnt with motivated young researchers and operators, eager to contribute to the ecological transition of the aquaculture sector.
The GAIN Summer School “Ecological Transition in Aquaculture” will provide key concepts and tools concerning: precision aquaculture, circular economy, sustainability assessment, policies and markets. Students will get an up-to-date knowledge of key ideas in these areas and then will be led through the GAIN innovations, thus discovering how the main challenges in aquaculture field can be dealt with by adopting the GAIN approach to the ecological intensification of this sector.
Talks delivered by GAIN experts will be complemented by contributions from other EU projects, focused on aquaculture ecological transition, and worldwide recognized authorities. Students will be engaged in demonstration sessions, using virtual tools, e.g., mentimeeter, and encouraged to interact within focus group.
The Summer School will be held Onlinefrom August 30th to September 3rd, 2021.
Five morning sessions, from 9:30 to 13:30 CEST, will be complemented by two afternoon sessions, from 14:30 to 16:30 CEST, for a total of 24 hours of training. The participation is completely free of charge.
Official language of the school is English. The School will admit up to 40 students. The admission is based on a CV and a motivation letter. Deadline for application is August 6th.
There are two sides to everything – two sides of a coin, two versions of a story, the good and the bad, the yin and the yang, so what’s the deal with tech? There is a running assumption that technology was developed for the good of humanity, but now that we have it, we have seen the double edge-sword of power.
On one hand, we have the fastest access to information right at our fingertips, connecting people from all areas of the world. On the other hand, we have experienced how addictive devices and apps are, comparisons, and the withdrawal from society.
But let’s look at this from the viewpoint of aquaculture. Technology has improved the state of farms by providing important data, statistics, accessibility to information, the ability to improve animal welfare and so on.
Since farmed fish has taken a bigger slice of our seafood choices, also because of the decrease in wild fish populations, integrated technology-based solutions bring the potential for reliable sources of information that promote eco-intensification and efficient fish farming. So, tech is not so bad, if used properly.
Yesterday we launched the official GAIN project Youtube channel:
The GAIN project aims are to promote the eco-intensification of aquaculture. But what does this mean?
To sustainably farm more fish in the same area, i.e. to make more with less! With the combination of precision aquaculture, improved feeds and re-using secondary products while reducing waste, we aim to grow a healthier and environmentally friendlier fish.
A goodfish: tasty, nutritious, sustainable and happy.
To define this ’goodfish‘ we need to understand its economic and environmental sustainability, welfare as well as its nutritional and taste qualities. This way we can support consumers and businesses with metrics based on good data that compare seafood options and guide good choices.
This is the end game of GAIN: to help provide more and better seafood for the future.
Over the past few decades, technological advances have completely revolutionized our society. It has influenced the way we live our lives, from the way we watch TV, to the way we conduct our scientific research. However, the aquaculture industry has fallen by the wayside. Big data, collected and distributed to our hands in the form of apps, have begun to dominate our world, so why is this not the case in one of the fastest growing industries in the world?
Atlantic Canada has recently emerged as a global leader in ocean technology, as well as playing host to one of the largest aquaculture companies in the world, Cooke Aquaculture. We have the unique opportunity of being surrounded by innovation. We are able to work side by side with the developers, as well as the consumers, to field test new technologies, and optimize their performance prior to commercialization.
However, aquaculture is still a relatively young industry, often operating in remote places, so introducing the use of technology has been difficult. Through research projects, we have been able to merge two key industry partners: ocean technology via InnovaSea, and salmon aquaculture, through Cooke, in order to improve management practices.
Meredith’s research focuses primarily on using real-time sensors to study water quality parameters, like oxygen and temperature, to understand how they vary through a farm, and what may influence these variations. At the same time, Caitlin uses acoustic telemetry to track fish movement in order to understand fish behaviour and improve welfare management. These two projects together allow us to provide a more holistic view of fish farming to create a more sustainable industry.
We hope that our work will help inform other aquaculture industries throughout the world, to become more innovative, improve farming practices, and ultimately create happier and healthier fish, with the ability to feed a growing population.
To produce a good seafood product according to ecological, welfare and human health aspects we also have to consider the economic side of the coin. The use of sustainable alternative feed, close monitoring of the production conditions or the valorisation of side-stream products is beneficial for a more sustainable production, but will also come at a cost. How high is this cost? Which production benefit or who (the consumer?) will compensate for these costs? What about the whole sector impact?
These are very important questions for farmers and the seafood industry in general, which we seek to answer within GAIN. In order to do this on farm-scale we use a so-called “typical farm approach” implemented by the agri benchmark network headed by the Thünen Institute in Germany. This is a micro-economic tool which allows to portray the typical production of a farmed species according to real costs, techniques and other inputs: all of it in great detail. In the end we can estimate, which market returns per kg fish should be achieved in order to stay (as) profitable (as before)!
Sustainable production methods themselves already benefit the farmer, resulting in better quality fish that needs less feed to grow to the same size, or achieving higher water quality which might also allow for higher stocking densities. However, such benefits do not always outweigh the full costs that adaptations towards sustainable production might involve. As long as follow-up costs of environmental impacts are not part of the market price (which is admittedly not an easy task to determine!), price differences are at the expense of sustainable products and need a transparent justification.
Originating from Germany, where public awareness and willingness to pay for more sustainable seafood products is higher than in other countries, I am convinced that a good market transparency is the way forward and I am excited to be part of this aim in combination with more sustainable seafood production within GAIN.
*The fish bought by the electro trashers band “Scooter” in the 1990’s and being the name giver for their song “How much is the fish”, cost 3.80 Deutsche Mark and supposedly lived for at least 18 years, which seems to be a quite good deal!
Have you ever wondered what the day of a fish looks like? Or what leads to their decision making? Well I have always been curious, and I turned that curiosity into a career path.
I am a PhD student at Dalhousie University studying fish behavior in aquaculture using acoustics. Now what does that actually mean? There are many ways to study fish behavior from putting tags into a fish and tracking an individual’s movement, to using sound to track an entire populations movement. I use both in my research to help understand different aspects of where fish swim and why.
To make a complicated technology simple, I use acoustics (sounds in the water) to send a sound signal up into the cage and, depending what type of sound is returned, will determine the amount of fish and their location in the cage. This information can be extremely useful to fish farmers as it can help them determine when to start and stop feeding, as well as how their fish respond to other environmental conditions (such as storms or harmful algae blooms).
The aim of studying fish movement is to help farmers better understand their fish and assist them in mitigating any stress that could impact the fish’s well-being. By providing this information, we can help make happier, healthier fish to help feed our growing population.
