Global shrimp production to have a record 2023, while salmon supply growth slows

Industry experts remain optimistic about long-term growth in aquaculture despite increasing concerns about costs and market conditions heading into 2023. Global shrimp supply is on positive trajectory, driven by a supply push from Ecuador, while turbulent salmon supply growth from Norway and Chile is expected to normalise in the short term.

Rabobank's new global aquaculture report summarises the key takeaways from the Global Seafood Alliance (GSA) GOAL Conference 2022, one of the seafood industry's most anticipated events.

Global shrimp supply could reach a record 6 million metric tons in 2023
Ecuadorian shrimp production is set to top 1.35 million metric tons in 2022. This would give Ecuador its largest single-year volume growth recorded, adding over 300,000 metric tons in supply – only slightly lower than Thailand's total annual production. Continued growth driven by Ecuador will lift the Americas over the two million metric ton mark by 2023.

Asia, the largest shrimp producer, is expected to experience its first production decline (-0.1%) since 2013. In 2023, however, Asian production is expected to rebound, lifted by higher production in China and India and a slight increase in Vietnam, pushing Asian production above 4 million metric tons in 2023.

Novel Sharma, Seafood Analyst at Rabobank, expresses bullish expectations for 2023, 'Overall global shrimp supply in 2022 is expected to increase by 4.2%, driven primarily by Ecuador and the Americas, which compensate for flat growth in Asia. The industry remains optimistic about supply in 2023, as Ecuadorian supply growth is expected to be supplemented by a strong recovery in Chinese production of 9.5%.'

Salmon production growth to slow in the coming years
After a volatile 2021 that saw Norway expand year-on-year supply by 11.9% and Chile contract by 7.7%, 2022 is expected to deliver the first overall salmon production decline since 2016. 'Slow growth in 2022 is expected to be followed by volume expansion of roughly 4% in both 2023 and 2024,' says Sharma. 'Supply for Norway and Chile in 2022 is expected to decline by 0.9% and 0.3%, respectively, followed by normalization of growth from 2023 to 2024, as both countries use regulatory controls to moderate supply growth.' 

Cumulative supply growth for Norway and Chile between 2022 to 2024 is expected to drop to 3.1%, compared to the previous decade's 7% compound annual growth rate. 'These lower growth expectations for Norway and Chile create an opportunity for Iceland and the Faroe Islands to become more relevant drivers in global supply this decade,' adds Mr Sharma. 

Feed costs a key concern for producers
Aquafeed and market prices have consistently been the top concerns for fish farmers over the past few years. Market prices were the key concern in 2021, according to Rabobank's 2021 Global Seafood Alliance GOAL Survey. 'However, the markets for feed ingredients have been volatile since start of the war in Ukraine,' says Mr Sharma. 'This has pushed aquafeed prices to the top as fish farmers' primary concern heading into 2023, with low expectations for prices to decline in 2023.'

He continues, 'Industry participants also highlighted growing concern about feed quality. Producers are also increasingly worried about their access to credit as central banks raise interest rates in order to combat inflation and lenders curtail credit.'

Three themes to shape Scottish aquaculture in 2023

Over the past 12 months, uncertainty in the form of inflation, energy prices and the cost-of-living crisis have brought the need for change into focus across many sectors. For aquaculture the collective goal of sustainability and future-proofing remains top of the agenda.

With high salmon prices per kilogram throughout 2022, we hope this will unlock further investment to fuel innovation and research next year. Local, national and international cooperation and collaboration will be central to this, with global action needed to help tackle some of the challenges faced across all seafood producing nations.

Seafood and finfish farming continues to play an integral role in the world's food system, providing a high-quality, sustainable source of protein while supporting economies and rural communities. As we look ahead to the new year, there are three key areas which we expect will shape the direction of travel for producers, the supply chain, academics and public bodies with an interest in Scottish aquaculture.

Mitigation of natural threats
Warmer waters causing algal plant or zooplankton blooms has been one of the biggest emerging challenges this year, and global warming makes it an ongoing concern. Harmful blooms can impact all animals and plants in the natural ecosystem – not just seafood – but we want to further support the sector with developing new tools and systems to better understand these threats.

Early warning technology, as well as increased knowledge to help spot trends and patterns, will enable seafood farmers to respond as quickly as possible to protect the health and welfare of their fish. Upskilling is also key to this across all areas of the sector. If more people are trained to look for patterns, the more likely we are to be able to introduce measures at the right time to deal with the potential impact.

Putting technology developments into action
We know that a progressive, modern mindset is needed to help future-proof the sector. Emerging technology and the greater use of data has been on the agenda for some time, but in 2023 we have the opportunity to shift from development to adoption.

SAIC has supported innovation projects over the year covering a range of areas, from the environment to fish health. Next year we want to see the knowledge gained through research being applied by all involved in seafood production – including regulators. Examples like Tritonia's 3D mapping of the hard-to-reach seabed can provide an extra level of confidence and reassurance when it comes to the environmental impact of fish farming.

Connecting the dots between Government strategies
In spring 2022, the Scottish Government published its Blue Economy Vision for Scotland and, in the first quarter of next year, we expect to see a new Vision for Aquaculture as well as a new Innovation Strategy. Proposals for highly protected marine areas are also out for consultation.

All of these provide a framework for Scotland's future, but we also need government to join up the dots between each strategy and work with the sector to create a thriving economy.

A good example of where this has worked before is the blue economy. Scotland's energy sector has modernised in a big way, transitioning to renewable tidal and wind-powered energy source. We should see seafood see seafood in the same way – moving from the old ways of doing things, catching wild fish, to cultivating the sea the same way we have the land through modern agricultural practices.

Scotland's geography, natural resources, expertise and history of innovation are all at play within aquaculture and, next year, we can be at the forefront of sustainable economic development in line with the Government's ambitions.

AlgaEurope successfully returns as record-breaking in-person conference in Rome!

This year's edition of AlgaEurope, the annual conference presenting scientific findings and trends in the algae and seaweed sector, attracted 425 delegates - a record in the history of the event – hailing from 44 countries. The first in-person event after a two-year hiatus, AlgaEurope, which took place at the Ergife Palace Hotel in Rome, Italy, 13-15 December 2022, offered a three-day program delivered by more than 90 expert speakers, covering scientific, technological and business-related topics in the global algae biomass sector. 

With plenary sessions addressing numerous topics, including seaweed sources and  applications, process, physiology, Biorefinery, feed, bio stimulant, genetics, Process, Bioremediation, Biomaterial among others, AlgaEurope is one of the most comprehensive conferences in its field.  

'AlgaEurope has this year attracted 425 delegates which is a first in the history of the  conference. The feedback we have received suggests that meeting up at an in-person venue where we use all five senses is highly valuable to accurately assess the merit of solutions and  trends. We are pleased that so many experts recognise this,' says Kuno Jacobs, Managing Director of DLG Benelux. 

Sharing their expertise and insight in the algae industry, experts from companies and renowned knowledge institutes explored numerous topics, from the use of 3D printers for seaweed snacks, how to determine of anti-microbial and anti-diabetic compounds from seaweed to low-cost microalgae harvesting. Company presentations and the Mentor's Evening were part of the special features. 

'The Scientific Committee was overwhelmed with proposals for topics this year. Never before have we had 289 abstracts submitted to the conference. This just goes to show not only that scientific research in Algae is currently high but also that an in-person venue is the preferred way to share new knowledge,' says Jean-Paul Cadoret, President of EABA. 

The organisers of AlgaEurope, European Algae Biomass Association (EABA) and DLG Benelux, had invited the high-caliber keynote speakers, Paul G. Falkowski from Rutgers, the State University of New Jersey, USA; Sammy Boussiba from Ben Gurion University, Israel; and Alison Smith from University of Cambridge, UK, who each opened one conference day with an outstanding presentation. 

In addition to the in-person presentations taking place at the venue in Rome, some 148 scientific authors presented their work in the poster area, a central zone at the conference centre, which also offered a trade show area with some 20 companies presenting their projects as exhibits.

New report shows how marine protection in the Pitcairn Islands is helping to restore ocean life

Environment Secretary Thérèse Coffey has urged more countries to join the more than 120 nations who already support the pledge to protect 30 percent of the world's ocean by 2030.

Image credit: Luke Hosty
Speaking as global leaders came together to tackle the global biodiversity crisis at the UN Conference of Biological Diversity (CBD) CO15 in Montreal, Canada, the Environment Secretary led calls for more ambitious and meaningful outcomes for ocean protection and confirmed the UK will renew its role as Chair of the Global Ocean Alliance beyond COP15.

By continuing in this role, the UK will remain as one of the leading voices in pushing for ambitious ocean action and the implementation of the Global Biodiversity Framework in the marine environment.

It comes as Defra announced that £20 million in grants – worth between £250,000 and £3 million – will be made available to local organisations around the world to help tackle illegal fishing and fight marine pollution, as well as sustainably managing Marine Protected Areas (MPAs) and protecting rare habitats and species.

Alongside this, the UK will contribute a further £17 million of aid from the Blue Planet Fund to the World Bank's PROBLUE programme, bringing total UK support to PROBLUE to £25 million. To date, PROBLUE has helped over 100 projects in more than 70 countries, including supporting the ASEAN regional plastic waste trade, and India's transition to a regulated sustainable fishery regime.

Speaking at the Convention on Biological Diversity COP15 during IOC-UNESCO Ocean Action Day, Environment Secretary Thérèse Coffey says, 'It is almost impossible to overstate the importance of a healthy, safe, sustainably used ocean for millions of people all around the world.

'I'm delighted to confirm that the UK will continue as Chair of the Global Ocean Alliance where we are committed to securing the maximum possible ambition and achieving the greatest possible impact to put nature on a road to recovery and help us protect at least 30% of the global ocean by 2030.'

The UK's £500 million Blue Planet Fund supports developing countries to protect the marine environment and reduce poverty. Initial investment of £20 million for OCEAN (Ocean Community Empowerment And Nature), a new competitive grants programme, will support innovative proposals from in-country organisations that secure healthy marine ecosystems and reduce overfishing. They will also ensure communities have increased capacity to manage marine pollution.

PROBLUE, a World Bank Multi-Donor Trust Fund, supports projects around the world that focus on the sustainable management of fisheries and aquaculture. The UK Government's investment will help address marine pollution, support the development offshore renewable energy and help governments around the world to better manage their marine and coastal resources. Since its launch, PROBLUE has provided support to over 100 projects in more than 70 countries.

Pitcairn Islands in focus
The UK Government's leadership on ocean protection extends across the globe, as new survey findings from Cefas (Centre for Environment, Fisheries and Aquaculture Science) and Blue Abacus has today revealed.

The Pitcairn Islands, a UK Overseas Territory in the Pacific Ocean, are home to one of the world's largest Marine Protected Areas (MPA) – three-and-a-half times the size of the UK. Its waters are some of the most remote and understudied in the world and contain rare and endangered species.

Established as a no-take zone in 2019, Pitcairn's MPA area prohibits commercial fishing, drilling and other extractive activities. Shark fishing was also banned in 2018.

A two-week expedition in 2021 funded by the UK Government's Blue Belt Programme uncovered key findings on rare species like sharks and humpback whales, in addition to the impacts of climate change on coral reefs. Key findings include:

  • Sharks were observed in over half (66%) of all the underwater surveys, with multiple species (such as Grey Reef shark, Galapagos shark and the Whitetip Reef Shark) observed in half (51%). It suggests that the ban on shark fishing has had an impact in supporting healthy shark populations, which are higher than the global average (it is estimated that sharks have disappeared from a quarter of the world's reefs).
  • Six individual humpback whales were seen on the seabed with many more recorded from surface observations, including mothers and their calves. The age of the calves indicates that the whales are using the Pitcairn MPA as a calving and nursery ground safe from human activities and threats.
  • A total of 7,319 individual fish were recorded from 203 different species, including endemic fish species, such as the many-spined butterflyfish (Hemitaurichthys multispinosus).


Simeon Archer Rand, Senior Marine Advisor at the Centre for Environment, Fisheries and Aquaculture Science (Cefas), comments, 'The results of this landmark survey are a significant success for the Pitcairn Islands. This community in the Pacific Ocean is guardian of one of the world's largest no-take Marine Protected Areas, providing a sanctuary for marine life in the vast Pacific Ocean. The island has strong cultural links to the ocean and its passion to protect it is clearly shown in its actions.

'Since 2016 we in the Blue Belt Programme have assisted the island community to further their ability to monitor their marine environment, as well as strengthen the governance of the invaluable MPA.

'The survey data collected will help Pitcairn to effectively manage the MPA, ensuring these key habitats are protected into the future. But there is still a lot to learn. We are just beginning our journey in terms of understanding this globally important region.'

From 2016 until March 2022, the Blue Belt Programme has been supported by £35 million of government funding, with a further £8 million committed this financial year until March 2023.

The Antarctic krill fishery is the cleanest fishery in the world, according to new research

A new science paper, published in Fisheries Management and Ecology, concludes that the Antarctic krill fishery is the cleanest fishery in the world in terms of it's extremely low bycatch rate. Observers collected registered bycatch data from the Antarctic krill fishery in the Southern Ocean during the 2010–2020 fishing seasons. They found that the total catch of Antarctic krill increased from 200,000 tons to 450,000 tons, with the greatest increase over the last three years. Following an international method used to analyse such data, the observers found that the bycatch ratio (0.1–0.3%) was stable and well below other fishery bycatch levels.

'Overfishing is a big problem across the world's fisheries,' says PÃ¥l Einar Skogrand, VP Policy and Impact, Aker BioMarine. 'However, this new data is very positive and demonstrates how krill fisheries can operate sustainably by ensuring a healthy population of target as well as non-target species in its fishing area. The krill fishery's low exploitation rate of the biomass, in conjunction with these new findings on the low bycatch, proves that the krill fishery operates well within ecosystem boundaries and is becoming a real model fishery on a global level.'

Krill, an important marine resource
Krill is the world's biggest biomass and the most underutilised marine resource. The enormous swarms of krill in the Southern Ocean are so dense they have been viewed high up above our earth's atmosphere and can be seen from space.

One key indicator to the healthy size of the krill mass is the growing abundance of whales and seals in Antarctica, which can be attributed to ample access to their main food sources, such as krill. The resurgent populations of these animals is a sign that they can thrive in fishing areas such as the Southern Ocean without an imbalance to the ecosystem.

Furthermore, the regulatory body of the Antarctic fishery, the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR), ensures a healthy krill stock by using a precautionary, ecosystem-based approach designed to prevent krill harvesting that will have a negative impact on a harvested species or other species in the ecosystem. CCAMLR has set a catch quota of less than one percent of the total biomass in the area regulated for fishing which makes it one of the most precautionary in the world.

Eco Harvesting contributes to almost zero bycatch rates
Eco Harvesting is Aker BioMarine's patented technology for continuous trawling. This technology ensures efficient and safe harvesting as the trawl is kept submerged under water for long periods at a time, compared to traditional trawling, where you haul up to ten times a day. When it comes to fisheries, hauling is regarded as high risk, specifically when the trawl is exposed and can lead to bycatch of non-target species and entanglement of birds. Eco Harvesting minimises this risk with lesser hauls. The system is also fitted with a mammal exclusion device and monitored by acoustic sensors ensuring mammals do not enter the trawl.

'At Aker BioMarine, our Eco-Harvesting technology helps us harvest krill in a sustainable and environmentally friendly way,' says Frank Grebstad, SVP Vessel Operations, Aker BioMarine. 'The mammal exclusion device within our Eco-harvesting technology has most definitely played a role in the low bycatch numbers as it helps reduce the risk of by-catch. Our operating model on fishing ground allows us to fish the high-density krill aggregations, this is key to our strong bycatch record. If we were to chase the lower density krill swarms in Antarctica there would certainly be more bycatch of other species in the mix and the krill fishery would not be such a clean fishery.'

'Antarctic krill is, and will remain, a novel part of the solution for our future food systems," adds Mr Skogrand. '800 million people are depending on food from the ocean today, and by 2050 this number will double. This makes krill the world's most abundant marine resource, not only an opportunity but a responsibility to utilise for health and nutrients. We already knew that the krill fishery is one of the best performing fisheries in the world in terms of ecosystem management, and this recent research indicates that it is also second to none in terms of how it actually operates and secures clean catches and low impact on the surrounding ecosystems."

Scientific review suggests krill meal is key to cost-effective and nutrient-rich shrimp feed formulations

The scientists behind a recently released review article conclude that krill meal is an effective functional ingredient for shrimp feed that can mitigate some of the challenges related to the stagnating supply of fish meal, including nutrition and growth performance, while remaining cost effective for producers.

'Across the aquaculture industry, we are seeing changing feed formulations due to supply challenges and cost pressure. For shrimp farmers, this means that they need to take a new approach to their feed formulations and find the right ingredients to maintain high nutrition, growth performance and overall cost-effectiveness, while keeping sustainability top of mind,' says Lena Burri, Director R&D for Animal Nutrition and Health at Aker BioMarine.

A functional ingredient that stimulates growth and health
The Labomar and Aker BioMarine review emphasises the need to address the risk for missing essential nutrients in the dietary feed formulations for shrimp. Krill meal, as a functional feed ingredient, has shown through previous research that it can improve attractability, palatability and general health in shrimp.

'Besides its well-balanced amino acid profile, krill meal is rich in phospholipid-bound omega-3 fatty acids and adds further value to the feed due to its high levels of astaxanthin and choline, all of which are important for shrimp development at various life stages. In recent years, krill meal has become one of the most studied feeding effectors for shrimp,' says MsBurri.

According to the review article, krill meal is an increasingly well-recognised ingredient in the aquaculture industry due to its feed attractant and palatability enhancer capabilities. In previous research, krill meal has been studied alongside other marine ingredients, from salmon meal to squid meal, and has consistently proven to be the most effective at increasing the feed intake and improving the overall growth performance in both shrimp and fish.

Cost optimisation is possible with krill meal in the feed
'The dietary feed represents one of the main cost elements in shrimp production, which makes optimization of the feed formulation critical for producers. We have seen through years of study that including just three percent krill meal in the shrimp diet can reduce feed cost and improve performance and feed intake in fish meal-challenged diets,' explains Alberto Nunes, Professor and Aquaculture Nutritionist, Labomar.

'Our theory is that the growth enhancement factors that we've seen in our previous studies of krill meal for shrimp is due to the balance between krill's high feed attractiveness and stimulation with its contribution of key nutrients,' adds Mr Nunes.

The review article, titled 'Developing sustainable, cost-effective and high-performance shrimp feed formulations containing low fish meal levels', was authored by Alberto J.P. Nunes, Lise Lotte Dalen, Geronimo Leonardi and Lena Burri. The complete article is available HERE

Sanford announces purchase of first-of-its-kind fishing vessel

New Zealand seafood company Sanford Limited has announced it has signed a contract with Netherland's based Damen Shipbuilding Maaskant for the design and build of a new scampi vessel for operation in the Southern Ocean. The vessel will contribute to Sanford's target of reducing the carbon footprint from its direct operations by 25 percent between 2020 and 2030.

Sanford Chairman Sir Robert McLeod says, 'this exciting new vessel build signals our intention to invest in our core business, to improve our efficiency and environmental performance of our fleet. It strengthens our ability to supply exceptional New Zealand seafood both domestically and to the rest of the world.'

Sanford CEO Peter Reidie says, 'the introduction of this modern vessel is a significant milestone in Sanford's strategy for our Wildcatch business. It will be a major step forward in resilient vessel design, which will give us the ability to fish in more challenging conditions. This investment of circa $30 million shows a strong commitment by Sanford and its Board, to sustaining our core business and our fishing fleet.'

The vessel will be built in the Netherlands at Damen Maaskant, the home of Damen fishing vessel build and repair since 1948, with an expected delivery in 2025.

To contribute to Sanford's target of reducing scope 1 and 2 GHG emissions by 25 percent from 2020 to 2030, this vessel will employ low emission diesel/electric power as well as a number of other innovations which make it greener and safer.

More engineering facts about Sanford's new vessel:

  • The new vessel will have a new diesel-electric system which works a little bit like a hybrid. It drives the main shaft and propellor with electric motors during normal operations, which allows the diesel generator to operate at maximum efficiency for longer periods of time, as well as sending the electrical energy generated to where it is needed throughout the vessel.
  • It will also have electric trawl winches which interact with the diesel electric system and generate power when they are working, helping keep our carbon footprint down.
  • The fans and large motors are on variable speed drives. In colder climates in or near the Southern Ocean, the fans can slow down to reduce energy usage.
  • Sanford has focused on using a robust long-lasting paint and anti-fouling coating system, which will reduce our paint consumption and reduce solvent release to the atmosphere.
  • The diesel electric propulsion system has an emergency 'come home' motor for safety. This means that if the main propulsion motor breaks down, the emergency motor will get the vessel home.
  • The advantage with its diesel electric motor is it starts and stops diesel generators as required. There is a selector switch on the bridge that can change how the electrical generation is set up, essentially it will use the least power required at any given time and for any given function.
  • The refrigeration gas used is CO2, still a greenhouse gas, but far better than the chlorofluorocarbons (CFC's) and hydrochlorofluorocarbons (HFC's) alternatives.
  • A scale model of the new vessel design has been extensively tank tested by Marin, to maximise seakeeping and vessel safety.
  • Plus, it will have the latest in machine guarding for crew safety, advanced bird protection for seabird safety and enhanced waste management to minimise any emissions.

Offshore fish farm technology could quadruple Scottish production

New technology to support seafood production in exposed offshore locations could unlock an additional £4.2 billion in turnover for Scotland's aquaculture sector, following the results of a pioneering research project led by start-up Impact-9.

The company's Net9 system – a submersible, floating structure which utilises the ocean's natural ecosystem and conditions – is one step closer to becoming a commercial reality, with a proven design concept now ready to be tested at scale.

The breakthrough marks the end of the latest phase of the £200,000 Inflatable Marine Products for Aquaculture Containment Technology project (IMPACT), which was funded by the UK Seafood Innovation Fund (SIF) with additional support from the Sustainable Aquaculture Innovation Centre (SAIC).

Engineers from Tension Technology International (TTI) and blue economy project developer Simply Blue Group were also involved in the development work, looking at regulatory issues and fish health and welfare as well as the cost challenges associated with bringing aquaculture into open ocean environments.

Once at full scale, a single Net9 pen could be used to produce up to 2,500 tonnes of salmon per annum,with oxygen-rich waters and conditions that mimic the wild helping the fish to thrive. Impact-9 has identified an opportunity to use the new technology within existing and planned offshore wind energy zones, where a small portion of these zones – around 12 x 12 km – would be enough to house 280 pens and quadruple Scottish production.

The position of wind turbines is typically determined by water depths, currents, and the need to avoid shipping lanes, which are also factors that would influence the suitability of a location for offshore aquaculture.

John Fitzgerald, CEO of Impact-9, says, 'A move further offshore can pave the way for a new sustainable seafood industry of scale, worth billions of pounds in the UK alone. The economic potential is similar to that of offshore wind, however, it will occupy a relatively small amount of ocean real estate and could fit in with existing and planned offshore wind turbine arrays.

'In the same way that lithium-ion batteries are the key to green transport, we believe that smart flexible structural elements like those used in Net9 will be the enabler of offshore seafood production.

'The most exciting part of this phase of work was to see the positive cross-over between fish welfare and structural engineering. The potential for stormy weather is of course unavoidable in these environments, but the design of the system allows the net and the fish contained in it to move together with much more flexibility than a rigid structure.'

Impact-9's system uses a flexible structure which is designed to move with the waves and weather any storms, rather than fighting against the water, reducing the potential stress on fish.

Next year, the research team plans to begin building a unit suitable for technical demonstration at the European Marine Energy Centre (EMEC) in Orkney, which will also provide interested producers with an opportunity to see a model of the system in operation.

Tom Mackay, engineering manager at TTI, says, 'This is part of a systematic engineering approach to address technical novelty and undergo carefully managed tests to qualify that new features will perform as desired. The process is similar to offshore renewable systems development, and we have brought to bear expertise from that sector to help Impact-9 manage the risk of adopting their novel structures in the Net9 application."
