Aquaculture is a growing and increasingly important industry in many parts of the world, including Scotland, Chile, Norway, Greece and Turkey. It helps to sustain economic growth in rural and coastal communities which are often isolated from the more developed and industrialised areas of these countries.
Scotland's leading aquaculture firm faces prosecution over mass fish deaths during a raid where large amounts of pesticides were found on boats, which were estimated to have caused 6000-20,000 fish deaths and impacted other marine wildlife. A review of various aquaculture and fisheries news is provided, including topics such as genetically engineered salmon, fisheries quotas, new aquaculture facilities and research, regulations around fish welfare, and challenges to new fish farm plans from animal welfare groups. The document consists primarily of short summaries of recent news stories within the aquaculture and fisheries industries.
Innovation nation - How new developments in aquaculture are boosting the Scot...International Aquafeed
With an estimated market value of over £1.8 billion and Scottish salmon exports alone reaching over £500 million, Scotland’s aquaculture sector is fast becoming a core pillar for the future growth of the Scottish economy. However, with such a steep increase in the demand for fish products, there is a real need for innovation within the sector to stay ahead of the curve and provide a sustainable supply of healthy protein; not only for the present but for the future of a market that appears set to keep growing. Ahead of Aquaculture UK, CEO of the Scottish Aquaculture Innovation Centre (SAIC), Heather Jones, shares some of the organisation’s forays into finfish research projects and the ways in which is working with both industry and academia to enhance the whole of the Scottish aquaculture sector.
FISH FARMING TECHNOLOGY: The Faivre equipped trout farms of AbbevilleInternational Aquafeed
Amidst the picturesque countryside of Abbeville, Northern France, Darren Parris, Tom Blacker and Peter Parker from the International Aquafeed team, spent an afternoon late last year visiting trout farms. Our hosts were Phillip Jorgensen, fish farms manager, and Aubert Faivre, who is sales manager for Faivre.
This document outlines a project between SMARTAQUA and Ocean Matters to produce disease screened larval lumpfish from UK broodstock for the UK aquaculture market. The objective is to rear lumpfish larvae from broodstock caught in both south coast and Scottish waters. This will help reduce the UK salmon industry's dependence on lumpfish imports by contributing knowledge to produce sustainable larval lumpfish sourced from UK waters. The project involves knowledge transfer, gap analysis, larval rearing, weaning, research sampling, and market development activities. Outputs will include standard operating procedures, £1 million in private investment, disease screening of 7 pathogens, and a new product - disease screened native lumpfish larvae.
This document summarizes information presented at a sustainable aquaculture workshop in Dublin, Ireland. It discusses aquaculture production in Galicia, Spain, including that Galicia produces over 75% of Europe's turbot. It notes that while the economic, social and environmental requirements for sustainable aquaculture exist in Galicia, no new farms have been established since 2004. The document then describes Galicia's efforts to establish an aquaculture planning framework since 2008 to select suitable areas and facilitate new farms, but that this plan also has not resulted in any new farms. It argues that overregulation and an uneven playing field compared to imports are key barriers to sustainable aquaculture growth in Galicia and Europe.
They are what they eat - Enhancing the nutritional value of live feeds with m...International Aquafeed
Live feeds are often essential for larval fish. Live feeds are proven to be essential first-feed for many larval fish, essentially all those that hatch from small eggs with limited yolk reserves and often immature feeding and digestive functions. Live feeds provide larval fish with essential nutrients that are naturally ‘microencapsulated’ in bite-sized packages. They include a high proportion of easily-assimilated free amino acids and free fatty acids, as well as digestive enzymes and beneficial bacterial microfloras in the gut contents of the prey. The swimming activity of live prey also stimulates feeding responses in larval fish, a vital concern because small larvae with very limited metabolic reserves can quickly starve if they do not promptly begin feeding actively.

The document provides an overview of Marine Harvest ASA, a major salmon farming company. It describes the company's operations, revenues, and geographic presence. It then analyzes some of the company's key environmental, social and governance risks and opportunities. These include challenges with sea lice infestations, algal blooms affecting Chilean operations, tensions with indigenous groups in Canada, fish escapes, antibiotic use, and potential virus issues in Norwegian farms. The document evaluates the company's sustainability performance and initiatives to address areas like environmental impacts, climate change, worker safety, and product quality.
Due to their nutritional properties, several species of macroalgae have been used as dietary supplements for shrimps and other marine species. Since macroalgae represent a natural source of nutrients in the shrimp’s natural environment, attempts have been done to co-culture macroalgae and shrimps.
The global fish consumption for human nutrition increases. The supply of enough aquatic products is still possible, because the experienced fish capture peak in the 1990s is buffered by the increasing amount of fish from hatcheries, both onshore and offshore.
Gwind is developing a gyro-stabilized floating vertical axis wind turbine that addresses challenges of offshore floating systems like dynamic loads, anchoring, corrosion, and personnel access. GroFish is an all-natural organic treatment that enhances growth and disease resistance in over thirty aquatic species. EWOS documented a feed trial reducing marine proteins and oils in salmon feed.
Cage farming involves installing floating enclosures in bodies of water to raise fish. Unlike other aquaculture methods, cage farming has minimal long-term environmental impacts if the installations are removed. Cages can be placed offshore or in sheltered areas of oceans, estuaries, lakes, and reservoirs. Investments are low per kilo of fish produced with cage farming, and farms can be expanded gradually. The document provides information on starting a cage farming operation, including conducting feasibility studies and environmental assessments.
Equipment failure or operational errors are behind three out of four farmed salmon escapes. Two out of three escapes are due to holes in sea cage nets according to a new study.
The document summarizes the development of a new stock protection system for salmon farms in Tasmania to prevent seal attacks. A Danish company worked with an Australian salmon farmer to develop ultra-strong nets made of Dyneema fiber in a novel design. The key features are an outer seal net suspended above the water and separated from an inner containment net. This creates a safe work environment and has successfully reduced seal predation and costs from over $12 million per year to minimal. The system is being adopted industry-wide due to its effectiveness. Accurate biomass tracking is also discussed as important for farm productivity and profitability.

Australian aquaculture is in many ways at the crossroads. It clearly has potential but regrettably there are many things holding it back. Much of Australia has been based on the ‘boom or bust’ process and aquaculture is very much in that zone.
This business proposal is for Diamond Aqua Leads, a company that aims to develop Sri Lanka's ornamental fish industry. The company will culture freshwater fish, treat diseases, and provide fish food to enhance growth. It will work with local fish farmers and collectors to export ornamental fish. The company's mission is to establish a sustainable and fair trade system for ornamental fish that benefits rural communities. It will achieve this through fish breeding, disease control, export preparation, and building partnerships along the supply chain. The goal is for fish farmers to receive fair compensation and access international markets through Diamond Aqua Leads.
Norway is one of the leading producers of farmed Atlantic salmon, accounting for over 60% of global production. While salmon farming is an important industry for Norway, rapid growth has led to environmental sustainability challenges. The document discusses three emerging technologies - recirculating aquaculture systems (RAS), open containment offshore systems, and closed containment coastal cages - that have potential to address these challenges. It also presents a model for assessing the environmental impact of different salmon farming methods and identifies opportunities and barriers to advancing more sustainable technologies, such as adapting regulations, dedicated financing, independent research, and influencing consumer behavior.
Precision Aquaculture and the Access2Sea prpjectSara Barrento
A total of 157 participants from 33 countries attended the webinar on the Application of Sensors in Precision Aquaculture (#aquasensors) on the 25th of May, 2021. I gave to talks, this is my second talk to introduce the Access2Sea project
The document discusses opportunities for investment in recirculating aquaculture systems (RAS). RAS is a sustainable solution for fish farming that does not require direct water access, enabling production in various geographies. Key opportunities for investors include improving RAS technologies to decrease costs, developing new RAS facilities near major consumer markets, and scaling up existing RAS operations through increased production sizes or vertical integration. RAS has significant potential to meet the growing global demand for seafood in a sustainable manner.
At present, turbot (Scophthalmus maximus / Psetta maxima) is one of the marine fish species experiencing the highest levels of aquaculture production growth in Europe. Turbot is produced in Europe in the Channel Islands, Denmark, France, Germany, Iceland, Ireland, Italy, Malta, the Netherlands, Spain, the United Kingdom and Portugal, with a total production estimated at 75,598 tonnes in 2011 (FAO, 2013). Turbot production in Portugal began during the 1990s and has increased steadily ever since.
The document summarizes the key discussions and presentations from the NASF Marine Innovation Day conference in Bergen, Norway on March 5, 2013. It describes the high turnout of over 200 delegates and highlights from several presenters addressing major challenges and opportunities for sustainable expansion of global aquaculture, including the need for innovation in areas like feeds, disease management, environmental impacts, and accessing new markets. Breakout groups identified priorities like optimizing site selection and a vision paper will guide long-term solutions and actions.
The following are a selection of reports to help investors get familiar with the investment opportunities that exist in the fisheries and aquaculture sectors.
FISH FARMING TECHNOLOGY: The use of feed in recirculating aquaculture systems...International Aquafeed
One of the greatest operating costs in aquaculture is the use of commercial feed pellets, which can comprise of up to 50-60 percent of total expense in some farms.
The Salmonidae family, collectively known as Salmonids, comprises of salmon, trout, chars, freshwater whitefishes, and graylings, but it is the trout and Atlantic salmon, of the genus Salmo, which gives the family their name. A slender teleost fish, they can range in size between just 13 cm to a whopping 2 m in length. With a single row of sharp teeth, Salmonids are predators, choosing to feed on smaller fish, aquatic insects and small crustaceans. Despite spawning in fresh water Salmonids are mostly anadromous, spending their lives at sea, choosing only to return to rivers to reproduce.

The Asian catfish Pangasius, Pangasianodon hypophthalmus is recognised as a leading aquaculture food fish on world markets. The commercial culture of Pangasius was developed in the mid 1990’s in Vietnam and quickly expanded to production levels of nearly one million tons per year. Other countries including Thailand, Cambodia, Myanmar, Indonesia, Philippines, Bangladesh and India have adapted Pangasius as part of their aquaculture production. Pangasius can be successfully cultured in most tropical regions of the world however countries in the Western Hemisphere have been slow to embrace Pangasius aquaculture, in part, due to the lack of practical knowledge of the species food requirements during the larval and fry stages.
Mud crabs, also known as mangrove crabs, occur widely in estuaries and along tropical, subtropical and warm temperate coasts in the world. There are four species of mud crab (Family: Portunidae), Scylla serrata, S. tranquebarica, S. paramamosain and S. olivacea that are the focus of both commercial fisheries and aquaculture production throughout their distribution. They are among the most valuable crab species in the world, with the bulk of their commercial production sent live to market.
The European lobster (Homarus gammarus) is an ecologically important species of the North-eastern Atlantic which supports wild trap fisheries that are worth around £30 million each year to the UK alone. By weight the species is the highest-value seafood among those landed regularly in the UK and Ireland, where 75 percent of the ~5,000t annual landings for the species are made. As such, lobsters provide essential diversity to fragile inshore fisheries and vital income for rural coastal economies. However, populations across its range are pressured by rising exploitation, from which traditional fisheries management has failed to prevent extensive regional stock collapses in the recent past, and now struggles to stimulate recovery. While lobsters have long been transported as a live export commodity, chiefly to France and the Iberian peninsula, emerging markets, particularly those in East Asia, threaten to create additional demand for the species which far exceeds current capture yields. Improvements in hatchery rearing success have seen a number of recent aquaculture initiatives employed, in the hope of both generating restoration and improved sustainability of wild harvests, and instigating commercial aquaculture possibilities.
In the past 50 years, the global demand for fish products has doubled, and more than 45 percent of the world’s seafood today now comes not from wild catches, but from either land-based or offshore fish farms. To meet this rising demand for seafood worldwide, more fish have to be raised in fish farms, and aquaculture is an essential link in the agricultural chain.
When farming animals and fish, there is often a danger that we may assume that their dietary requirements match our own. However, those of the common carp, Cyprinus carpio, certainly do not.
Mexico, with a population of 122 million is the most populous Spanish-speaking country in the world. The country is known for its Pacific and Gulf of Mexico beaches and its diverse landscape of mountains, deserts and jungles. Ancient ruins such as Teotihuacan (Aztec), Chichen Itza (Mayan) and Spanish colonial-era towns are scattered throughout the country.
The quality and digestibility of proteins is one of the most important issues in shrimp nutrition. Marine proteins (mainly fish meal) can only be partially replaced by standard vegetable proteins like soybean meal.
KRILL OIL: Phospholipids that make a difference to filet quality and quantityInternational Aquafeed
The nutritional quality of larvae diets affects fishes’ fillet quality and quantity. Studies show that phospholipids increase fish larvae growth and development; so phospholipids are an essential component of the early weaning diet.
Carbohydrates are an excellent source of energy and carbon in feed formulations. They can be easily distinguished from the other energy yielding nutrients in terms of their abundance and low price. To illustrate, the collective global production of the major cereal grains i.e., maize, wheat and rice amounted to a colossal 2.5 billion tonnes in the year 2013 (FAO). The total carbohydrate content and the digestible fraction of starch and sugars in these grains can be roughly estimated to be about 2.1 and 1.75 billion tonnes, respectively (www.feedipedia.org). Besides, the unit cost of carbohydrate sources is almost three to five fold less than that of the protein and lipid sources of interest. Therefore, the inclusion level of carbohydrates in commercial fish feed assumes direct economic significance i.e., in terms of lower feed cost per unit weight gain.
Brewers' yeast and its derivatives have been used successfully in animal nutrition for decades. Leiber GmbH produces brewers' yeast products from their facilities in Germany, Poland, and Russia. Brewers' yeast is a high-quality byproduct of the beer brewing process, which is strictly regulated in Germany. Leiber produces various yeast derivatives for animal feed through processing, including inactivated yeast, autolyzed yeast with broken cell walls for improved nutrient availability, yeast cell walls containing beneficial glucans and mannans, and highly purified beta-glucans. These products provide nutrients, support immune function, and aid digestion when included in animal and aquaculture feeds.

3. A
quaculture is a growing and
increasingly important industry in
many parts of the world, including
Scotland, Chile, Norway, Greece
and Turkey. It helps to sustain economic
growth in rural and coastal communities
which are often isolated from the more
developed and industrialised areas of these
countries.
The modern aquaculture industry faces a
number of issues:
Disease
High rates of water extraction and
increased reliance on recirculated water
can lead to poor water quality, resulting in
increased outbreaks of viral, bacterial and
parasitic fish diseases which can decimate fish
stocks. Due to the intensive nature of fish
farming, fish stock is also highly susceptible to
infection from natural fish populations in the
feed water to the farm.
Regulation
Fish reared and released back into the wild,
as well as those endorsed by the regulatory
bodies such as the UK’s Marine Stewardship
Council, must be disease-free.
Water quality
To minimise the chance of infection
and disease, the water used in fish farms
and hatcheries needs to be of a minimum
quality. Ensuring this quality is not easy –
chemical treatment is not appropriate as it
harms the fish and cannot be released into
open waters.
To ensure water quality and to break the
infection cycle between fish farms and natu-
ral fish populations, a disinfection system is
needed to treat water entering and circulating
within fish farms.
The advantages of
UV disinfection
Ultraviolet (UV) is
ideally suited for treating
incoming and recirculated
water in fish farms and
hatcheries as it uses no
chemicals and does not
create by-products which
would harm the fish
stock, or other aquatic
life, on discharge. Unlike

CASE STUDY
Cultivos Huacamalal Ltda., Chile
Cultivos Huacamalal Ltda. of Chile uses
a Hanovia UV disinfection system for
its salmon hatchery in Rio Ignao in the
south of the country. The UV system
is part of a US$1.1 million water recir-
culation and effluent treatment system
provided by Atlantech Chile Ltda. of
Puerto Montt, Chile.
The UV unit treats well water
used for make-up supply in the water
recirculation system to control against
Infectious Pancreatic Necrosis (IPN)
RNA-virus. IPN is found in wild salmon
populations on the Pacific coasts of
both North and South America and can
cause severe mortality (up to 80%) in
fish up to two years old. It is a common
disease in hatcheries and is also capable
of transmitting epizootic conditions back
to wild populations.
Chile is one of the three major salm-
on farming countries in the world, along
with Norway and Scotland. Cultivos
Huacamalal is a new player in the
Chilean salmon aquaculture industry.
The company was formed by a number
of experienced partners in the fish
production and shipbuilding industry in
Chile and has signed an agreement to
supply product to one of the largest
salmon exporters in the country.

the expense of complex monitoring sys-
tems required for adding and removing
chemicals before the water reaches the
fish. In addition, it does not alter the pH
of the water. In fact, UV is now widely
regarded to be the most effective and
economical disinfection technique for use
in fish aquaculture.

7. UV applications in aquaculture
The applications for UV include treatment
of water in hatcheries, shellfish purging tanks
and fry rearing tanks. It is also used in fish
processing plants and well boats. UV is even
used to disinfect recirculation water in marine
parks and aquaria.
Some considerations
When installing UV systems, operators
need to be aware of which viruses, bacteria
or parasites are posing a problem and size
the UV systems accordingly. Hanovia usually
recommends a UV dose of between 120-
150mJ/cm2, but the final dose always depends
on a number of factors, including whether the
water is single-pass or recirculated.
Water needs to be treated at all stages in
the process, from the egg stage right through
to full maturity
All effluent water from hatcheries, process-
ing plants and well boats must also be treated
so as to protect the environment and stop
the possible transmission of disease to wild
fish populations
UV technology
UV technology is surprisingly simple to
install and use. A UV disinfection chamber can
usually be retrofitted to existing pipework and
circulation systems with minimum disruption
to the process.
All controls are automatic and mainte-
nance of the systems is usually restricted to
the replacement of the UV lamp every 12-18
months, depending on use. This is a simple
operation that can be carried out by on-site
staff. An automatic or manual wiper fitted
over the quartz sleeve surrounding the UV
lamp prevents the build-up of any deposits,
ensuring maximum levels of UV irradiation at
all times.
A significant feature of modern UV sys-
tems is the control mechanism which displays
a range of useful functions such as flow rate,
UV dose and intensity. The systems are
usually capable of logging up to one year’s
performance data, which can be downloaded
to a PC through an RS232 port. Linked into a
central computer, the control panel can also
be operated remotely, and allows the system
to operate around the clock.

Loch Fyne Oysters Ltd in Scotland
is using two Hanovia UV disinfection
systems for its oyster farm in Loch Fyne,
Cairndow, Scotland. The UV systems,
which were installed by Barr and Wray,
destroy harmful E.Coli bacteria from its
oyster and mussel depuration tanks.
Each UV chamber treats up to 150 m3
water per hour.
According to a spokesperson from
Loch Fyne Oysters, “The Hanovia units
were recommended to us by Barr and
Wray because of their 99.99% log
reduction of E.Coli, their robust, stainless
steel construction, their ease of installa-
tion and easy maintenance – including
easy UV lamp replacement and daily
cleaning with a manual wiper – and low
running costs. We also find the digital
run-time read-out very useful.”
