21/12/12: EWOS COO steps down; Spanish fish preferences; Nile tilapia in the Philippines

Hello, 
  • EWOS Chief Operating Officer (COO) steps down. Mr Kjell Bjordal will retire as COO from February 15, 2013 and will be replaced temporarily by Dr Einar Wathne. Mr Kjell Bjordal will step down when he turns 60 early next year. Revenue has increased more than tenfold and the operating result has developed even stronger during the more than 13 years that Kjell Bjordal had led what is now Cermaq's feed division.
  • Spanish consumers prefer home-grown fish according research. The study, published in the Food Quality and Preference journal, asked consumers to analyse factor when buying fish. Origin ranked highest above fished or farmed-raised, price and conservation method.  the Spain is the biggest producer of fish in the EU but in recent years domestic consumption has fallen. Read more...
What is most important when buying fish: the price, the country of origin, whether it is fresh or frozen or whether it is wild or farm-raised? The average Spanish consumer prefers above all that their fish comes from Spain, according to a study published in the 'Food Quality and Preference' journal. Spain is the largest producer of fish in the European Union but in recent years its population has consumed less fish, especially seafood.

20/12/12: ISA at Cooke Aquaculture; new salmon farms in Nova Scotia and Scottish farmers get European funding

Hello,
  • A new case of ISA has been detected at a Cooke Aquaculture site in Newfoundland, Canada. According to Nell Halse, the vice-president of communications at Cooke Aquaculture, the site is a medium-sized farm with four cages that contain about 300,000 fish. The salmon are about halfway through their growth cycle and would have been harvested and marketed out in August of 2013. The company is working with the Canadian Food Inspection Agency (CFIA) to deal with the outbreak. Read more...
  • The Nova Scotia government has given the go-ahead for two controversial salmon farms in Jordan Bay near Shelburne. Operated by Kelly Cove Salmon, a subsidiary of Cooke Aquaculture, the sites will be home to up to 700,000 fish. The farms faced opposition over concerns that large-scale aquaculture could threaten wild species. Read more...
  • Scotland's fishing industry is set to get £5.8 million in European grants. 121 projects from across the country have benefited from the latest round of European Fisheries Fund (EFF) pay outs. The main benefactors are Shetland Aquaculture and Lossie Seafoods in Buckie which both received over £300,000 each. Read more...

Event: IAI AquaCulture Expo 2012


ISRMAX India

December 13-15, 2012
IARI Ground, PUSA, New Delhi, India

This December the IARI Grounds, PUSA, New Delhi will play host to eight concurrent trade shows over three days.

Perendale Publishers Ltd, the publisher of International Aquafeed magazine, is working in association with Pixie Consulting Solution Limited to put on what promises to be an action-packed series of events. The shows will focus on the Indian agriculture industries providing visitors with plenty of opportunities learn amore about agriculture, aquaculture and rice and grain production.

One of the trade shows, the IAI AquaCulture Expo 2012, is dedicated to all things fishy. It is an exhibition and conference on the aquaculture and fishing industries with a global emphasis. Exhibitors from all over the world will launch, exhibit and promote new products and services from both industries. Visitors will be able to get the lowdown on the latest developments from the fields of aquaculture technology, fish feed, fish health and equipment.

Why India?
India has an impressive international ranking.  It is second in the world for farm output and also the world’s second largest producer of wheat and rice. In addition, the country is within the top five producers of over 80 agricultural products.

At 1.2 billion, India is home to 16 percent of the world’s population and boasts the world’s fourth largest economy.

Annual growth is eight percent so the demand for and opportunities within agriculture and aquaculture are growing every day.

Indian aquaculture
With a coastline of 8,129 km, 2 million sq km of exclusive economic zone and 1.2 million hectares of brackish bodies of water, India offers a vast potential for development of seafood production.
Indian seafood exports account for around 10 percent of total production, more than 80 percent of which is made up of shrimp, cuttlefish and squid.
Fresh water fish farming is booming at the moment and is expected to grow annually at 8 percent.

Other events at ISRMAX
The ISRMAX Rice & Grain Expo 2012 looks at the complete value chain, providing a space for interested parties across the industry to meet.
The IAI Expo Poultry & Meat Expo 2012 focuses on the Indian meat and poultry industry. The country has potential to increase the consumption of meat and meat products in domestic and international markets. Despite this, there is a lack of advanced technology, particularly at the farm level, which is a constraint in enabling this sector to take a quantum jump in production and productivity.  The event aims to provide a platform for all stakeholders to share knowledge and technology.

Big DNA Ltd awarded part of €6 million European project to develop new fish vaccines

Leading Scottish life sciences firm Big DNA, located at the Roslin BioCentre, Edinburgh, announced today that it is part of a European –wide consortium that has been awarded European Union funding under the €6 million ‘Targetfish’ project.  This major project is aimed at developing new aquaculture vaccines, of which Big DNA’s proprietary phage M13 based chimeric vaccine technology, will be part.
 

The Framework 7 Targetfish Project, which lasts for five years, includes 30 collaborators, both industrial and academic, across 10 EU countries, and aims to develop affordable and effective vaccines against a range of economically important fish diseases, including those affecting salmon, trout and sea bass, amongst others.

Scotland is particularly well represented in the project which involves four Scottish-based commercial companies and research institutes, of which Big DNA Ltd is one, and, which lays testament to the expertise available in the country for commercial aquaculture.

Dr John March, CEO of Big DNA commented, “We are delighted to be part of this significant European initiative, which recognises the potential of our chimeric M13 phage-based vaccine technology for use in applications such as aquaculture.  This further expands the utility of our platform technology in addition to our core interest in developing human healthcare products.”

Rhona Alison, senior director of life sciences, Scottish Enterprise, said: "This news is very exciting for both Scottish Life Sciences and Big DNA. The level of Scottish participation as a whole in this European programme underlines the strength of the aquaculture sector here and builds on Scotland's increasing reputation as a leading international hub of life sciences expertise."
 

Big DNA has developed fish vaccines which are able to be administered through immersing the fish in tanks of water containing the vaccines, thus eliminating the need for use of needles which can damage the fish.

07/12/12: Sex change prawns, seafood flavour wheels and Seafood in Alaska

Hello,
I was in London yesterday collecting a visa for India and making arrangements for the IAI Aquaculture Expo. It's all very exciting and I can't quite believe the event is just under a week away. But for now, here's the news...
  • Ben-Gurion University, Israel has developed an advanced gene-silencing biotechnology for aquaculture that changes the sex of prawns and yields faster growing all male populations, resulting in greater output and farmer income. “The technology is sustainable because it doesn’t use any chemicals or hormones and does not create genetically modified organisms,” said BGU’s Prof. Amir Sagi. “This is made possible through the unique monosex culture of prawns, which we can obtain by using our original discovery of a naturally occurring, androgenic hormone that influences their gender.  Since males are faster growers, this discovery could help farmers increase their income.” Read more...
  • I have often heard salmon tasting described in similar terms to wine tasting but the Australian Seafood Industry has taken this analogy one step further by creating the Seafood Flavour Wheel. The wheel categories 12 species into different aromas and flavours. According to the tasting notes, a fillet of pan-fried King George whiting is simailar to roasted nuts, egg white and mushy peas. What do you think?  Read more...
  • Prince William Sound Aquaculture Corporation (PWSAC) has released the results of a study on the impact of its programmess on the economy, Alaska's seafood industry, sport, subsistence and personal use fisheries. Significant benefits to the state and regional economy were outlined, along with ways in which the programs could be expanded to produce greater economic benefit. The study covered direct and indirect job creation and earnings. The study also examined market conditions for salmon species.  Read more...

New Omega-3 film launched by IFFO

IFFO, the Marine Ingredients Organisation has launched an informative video about Omega-3s, nature’s own health products entitled ‘Marine Omega-3 – The Healthiest Fats’.  The film is a response to growing scientific and consumer interest in the subject and can be viewed below.


The two healthiest Omega-3s are essential long-chain fatty acids EPA and DHA which cannot be made by the human body. They can be consumed by eating certain foods - predominantly fish and seafood but particularly oily fish such as anchovy, salmon and mackerel which contain some of the highest concentrations of EPA and DHA.

Globally, cardiovascular diseases are the primary cause of death and more than 450 million people are suffering from mental disorders world-wide (WHO data). The argument for increasing the consumption of Omega-3 is a convincing one. 

Professor Michael Crawford, Director of the Institute of Brain Chemistry and Human Nutrition at Imperial College, London features in the IFFO video. His research work centres on the health benefits of long-chain fatty acids and the important relationship between nutrition and membranes in the body.

Wellbeing and medical health concerns have helped drive the demand for fish, placing wild fish stocks under pressure. However, farmed seafood is now a major contributor of Omega-3 and can be a sustainable resource. To maintain beneficial levels of EPA and DHA within farmed fish, they must be fed on a diet that’s high in marine products. Without this, beneficial levels of EPA and DHA in the finished seafood reduce significantly. As a result the aquaculture industry is increasingly putting minimum requirements in place for the inclusion of EPA and DHA in fish feed.

The video also demonstrates that the regular intake of omega-3 capsules, favoured by some consumers, is a good way to increase levels of EPA and DHA. However, care has to be taken to ensure that the oil is of marine origin, since vegetable oil from land sources does not contain sufficient levels of these critical fatty acids.

Andrew Jackson, Technical Director at IFFO said ‘We developed the Omega-3 film to highlight the important part the fishmeal and fish oil industry plays in the food chain and in human health. The industry’s responsible approach to sourcing and production under the IFFO RS certified producers scheme offers consumers complete confidence in the products they are purchasing.’

To help buyers looking for responsible sourced fishmeal and fish oil, IFFO provides a Global Standard for Responsible Supply (IFFO RS). This is an independent business-to-business certification programme that enables a compliant factory to demonstrate that it responsibly sources raw material from well-managed fisheries and responsibly converts it into pure and safe products, including fish oil for human consumption.

With the global population growing, sustainable sources of marine oils will be a key factor in being able to provide a healthy future for all.

04/12/12: Zebrafish, salmon and shrimp get the Aquaculturist blog treatment

Hello,
  • Predigetsed protein in feed may help improve salmon health says NIFES. A recent study by the organisation shows that salmon that are fed moderate amounts of predigested fish protein have lower levels of intestinal fat, and that this may have positive effects on their health. For the study groups of salmon were fed diets containing 20 percent fish meal in their feed and the rest of the protein arrived from plant protein., The fishmeal was replaced with 5 to 20 percent predigested (hydrolyzed) fish protein. “This had no effect on feed intake, but growth reduced as the amount of predigested protein increased,” says NIFES research scientist Marit Espe. Read more...
  • Another NIFES story caught my attention today - research has shown that zebrafish feed needs to be standardised to produce good medical and nutritional research results. “If zebrafish are to be a good research model, and if we want to compare the results, we will have to develop a standard diet for these fish,” says NIFES Mari Moren, head of research. Zebrafish fans should look out for the January/February 2013 issue of International Aquafeed in which editor Prof Simon J Davies will report on diets for the species. Read more...
  • Shrimp is big business so any product which claims to improve digestion will be of interest to farmers and scientists alike. This article explores the impact of Spurulina diets on gut health. Read more...

Aquaculture view: On the Estimation of the Digestible Nutrient Contents of Finished Feeds


Aquaculture view

Aquaculture view is a column in each edition of International Aquafeed magazine (IAF), written by Dominique P Bureau.

Part of the IAF editorial panel, Dom has a PhD in Nutritional Sciences from the University of Guelph, Canada.

Today he teaches various undergraduate and graduate courses on animal nutrition and agriculture at the University of Guelph. Between 2007 and 2009, he coordinated the “Paris Semester”, a study abroad program for undergraduate students at the University of Guelph.

He serves on a number of international committees, including the US National Research Council Committee on Nutrient Requirements of Fish and Shrimp.





See all of the Aquaculture view columns here.

November - december 2012


On the Estimation of the Digestible Nutrient Contents of Finished Feeds

A very large proportion of aquaculture feed manufacturers are now formulating their feeds on a digestible nutrient basis. This progressive move from formulating on a ‘total nutrient’ basis to formulating on digestible nutrients is praiseworthy since it is providing a more rational basis for the production of cost-effective diets adequately meeting the nutrient requirements of animals.

Every year, an increasing amount of information of the digestibility of nutrients of different ingredients is becoming available. This information is informally compiled in a number of reference documents and increasingly used by commercial feed formulators. The question arises as to how reliable is the available information and how it is best used. In a context of very high feed commodities prices, the impact of overestimating or underestimating digestible nutrient contents of feed ingredients can translate into significant economical impacts.

For example, variations as low as two or three percentage points in the digestibility of protein or lipid sources can translate into variations of as much as $10 to 30 per tonne of feed produced, clearly not something negligible.

For years, the debate around estimates of apparent digestibility was on methodological issues (e.g., feces collection methods) and perhaps more important issues have been neglected. I wish to briefly highlight two of these issues in this column.

Ingredients, such as poultry by-products meal, feather meals, meat and bone meals, and DDGS are increasingly used in commercial aquaculture feed formulations. A substantial amount of information of the apparent digestibility of protein, amino acids and energy of these ingredients is available in the reference literature. However, these ingredients are produced using a wide variety of equipment and processing and drying conditions. Consequently, significant differences may exist in the apparent digestibility of nutrients amongst lots (batches) of these ingredients. Very little work has been done to meaningfully characterise the variability of the digestibility and nutritive value of different lots of the same ingredient. This is a major issue for feed manufacturers since these ingredients are frequently sourced from several different suppliers (brokers) and these suppliers, in turn, frequently source these ingredients from different manufacturing facilities.

Another important issue is the way by which the digestible nutrient contents of finished feeds can be computed. In feed formulation, the nutrient contributions of different ingredients are used to predict the concentration of nutrient (or energy) in the finished feed. The contribution of nutrients of different ingredient is thus assumed to be additive. It is common for nutritionists to assume that the digestible nutrients and energy contents of feeds can also be calculated as the sum of digestible nutrient and energy contributions of different feed ingredients (calculated from the quotient of incorporation level in the feed, the apparent digestibility coefficient (ADC) and the nutrient content of the ingredient). While practical and generally effective, an increasing amount of evidence suggests that this type of approach may not be suitable for several types of nutrients.

A series of publications from the University of Guelph (Hua and Bureau. 2006. Aquaculture, 254: 455-465; Hua and Bureau. 2009. Aquaculture, 294: 282-287; Hua and Bureau. 2009. Aquaculture, 286: 271-276; Hua and Bureau 2010. Aquaculture, 308: 152-158) showed that the digestible phosphorus (P), starch and lipid contents of finished feeds could not be computed from the sum of expected digestible nutrient contributions of the different ingredients. This research indicated that the forms under which these nutrients were supplied (or found in the finished feeds), the levels and interactions between different forms of the nutrients, and the effect of some exogenous factors (e.g., water temperature, % gelatinization) had to be taken into account to accurately predict the digestible nutrient contents of finished feeds.

Fortunately, this research also showed that multiple regression equations provided a simple and practical approach of addressing this challenge. Equations where thus developed for predicting the digestible P, starch and lipid content of feeds manufactured using a wide array of feed ingredients. Unfortunately, most least-cost feed formulation software packages are not currently designed to carry out an optimization (least-costing) of the digestible P, starch and lipid contents of feeds on the basis of these equations.  However, these simple equations can be programmed into feed formulation software and the effects of changes in feed formulation on the digestible P, starch and lipid contents of the finished feeds be easily computed.

These issues should be on the radar screen of feed manufacturers and more systematic and commercially relevant work needs to be done by fish nutrition researchers on the important topic of estimating the digestible nutrient contents of feeds.

Today, Olmix is one of the world’s main specialists in 'green chemistry' and is one of the pioneers of the 'blue biotechnology'. Olmix has 12 subsidiaries worldwide, is present in 60 countries and employs 250 people. The Breton SME reached a turnover of €53m in 15 years, of which 80 percent was exported sales.  The company is well established in Asia where it achieves a 30 percent growth by year on average. In fact, the ASEAN area represents an increasing share of the group’s turnover. Olmix Group is listed on the Paris Stock Exchange and has seven production plants in Europe.

This interview appeared in the May June 2012 edition of International Aquafeed magazine



After 15 years of algae valorization, what are your observations?

Hervé Balusson (Olmix Group CEO): When I began to get interested in macro-algae, 15 years ago, people believed I was a marginal. However, the sea is unquestionably an amazing source of 'blue biotechnology'. The number of algae species in the world is estimated at almost one million. At the outset of the new millennium, the study of algae is one of the most promising ways to provide answers to mankind issues such as environmental, food and energy challenges. Nature has already the answers to take up these challenges.
Renewable biomasses, algae are rich in proteins, carbohydrates, trace elements and especially in active principles often underestimated.
Algae reflect the company’s philosophy as sustainable solutions: thanks to algae, Olmix is able to provide natural, efficient and universal solutions. By 'universal', I mean that our products have the capacity to adapt to various types of production, in different contexts.
The macro-algae high potential combined with our mastery in sourcing and industrial processes led us to technological breakthrough, to the development of numerous innovations and revolutionary products, particularly by the association of the mineral and the organic.
Our group has the advantage of being able to promptly launch its new technology at competitive prices on the market thanks to our well established international sales team. This territorial anchorage gives company open-mindedness and dynamism.

Aquaculture is today facing some challenges, what solutions do you provide?

Increasing production, fishmeal replacement, high quality products requirement (in compliance with standards and certifications), feed efficiency improvement, pathologies limitation, maintaining water quality … These are the challenges the aquaculture sector is facing today.
Olmix proposes solutions in line with the market concerns and provides a full range of products intended for aquaculture.
Fish meal replacement has for example generated a new problematic, previously unknown, the mycotoxins risk management, linked to recourse to plant origin commodities. MTX+ responds to this new demand by supplying an effective and reliable solution to control this risk.
The innovative nature of our products is intrinsically related to valuation of both nutritional and functional algae properties which ensure effectiveness and originality.
Solutions provided by Olmix are universal and meet the feed millers and farmers needs and are besides the result of a privileged relationship based on our proximity with our different partners.

Is the future of Olmix linked to algae valorization?

The group’s medium and long-term development is indeed predicated on the implementation of a complete sector for macro-algae valorization.
This year we are starting a large-scale project, the 'Industrial Strategic Innovation' program from Oséo called ULVANS, gathering 5 companies (OLMIX, PRP, MELSPRING, AMADEITE, AGRIVAL) and two French academic partners (South Brittany University, National Centre of Scientific Research from Mulhouse).
The aim of the ULVANS project is to create a sea lettuce valorization sector, from the harvesting to the marketing of innovative products destined for the animal and vegetable nutrition and health markets.

Health through algae, a new challenge for Olmix?

Our expertise in the knowledge and the mastering of active principles stemming from macro-algae opened up new fields of application. The group’s Research and Development teams focus today on the valorization of our innovations in the health sector.
The sea must be considered as an infinite reservoir of solutions, it contains the potential to solve major health issues.
'Health through algae' is the founding concept of the new Amadéite company which is developing breakthrough products dedicated to control animal and vegetable pathologies (immunostimulation, anti-infective agents, elicitation effect).

New factory to bring jobs to Timaru

Geoff Matthews, CEO of Mt. Cook Alpine Salmon Limited has announced that the company has commissioned the building of a new $6m salmon-processing factory in Timaru, to be opened in April 2013.

Mr. Matthews made the announcement at the South Canterbury Chamber of Commerce, Top Table function in Timaru, where he was guest speaker.

“The new factory will be commissioned in stages initially bringing 35 new jobs to Timaru and a further 40 jobs to follow, as Mt. Cook Alpine Salmon expands its production and an added-value smoke house is also commissioned in three to four years time,” he says.

Geoff Matthews says the site in Sheffield Street, and builder Chris Broadhead of Chris Broadhead Building Ltd, were chosen after an extensive twelve-month search and planning process, in which Mt. Cook Alpine Salmon evaluated a large number of options.

“Geographically we looked at a triangle between Twizel, as far south as Oamaru, and as far north as Rangiora. In the end the economics of basing a plant in Timaru, coupled with a skilled stable workforce meant that it was the best option.”

Mr. Matthews says that Mt. Cook Alpine Salmon is in the middle of a $20 million dollar capital expansion and it was always part of the companyʼs business plan to become vertically integrated.
“We see the commissioning of our own factory as a critical component of becoming masters of our own destiny, and to obtaining the best possible price for our product overseas,” he says.
Mr. Matthews says that commissioning of the plant in New Zealand is also bringing jobs back onshore.
Plans for the new factory

“Currently 80 percent of our export production has secondary processing in Indonesia. However, bringing jobs back onshore is not without its challenges,” he says.

“The challenge for us as a company is to up-skill our work force to meet and ideally exceed, the exacting standards that we currently obtain from our world-class processor, BMI, in Indonesia.”
“Commissioning the plant is therefore a vote of confidence in a New Zealand workforce.”

Geoff Matthews says that the plant will be export certified to the highest standards to be able to export to the key international markets of Australia, Asia, Europe and United States. The plant will also need to be certified to the Global Aquaculture Allianceʼs (GAA) Best Aquaculture Practice (BAP) standards.

“Earlier this week we announced that the Mt. Cook Alpine Salmonʼs farming operation has become the first aquaculture facility in Australasia to be GAA BAP certified, so our plant will also need to complete this certification.”

Matthews says the new plant has been designed to process, at full capacity, 3,500 metric tonnes of harvested fish, and to be as flexible as possible to ensure the company can take advantage of changes in markets needs.

Geoff Matthews said the willingness of the council and business community to engage with Mt. Cook Alpine Salmon also assisted greatly in the final decision to built in Timaru. “The company was very honoured to win the Supreme Award at the South Canterbury Business Excellence Awards,” he said.
Mr. Matthews also praised the commitment to the project by both builder Chris Broadhead, and Michael Broadhead of Lines in Designs. “Chris and Michael have worked extremely hard to get this deal across the line, and has been able to provide us a fantastic design and build option.”

29/11/12: Stories in rainbow trout in Lebanon and shellfish in Washington

Hello, 
  • Rainbow trout may not be native to Lebanon but farming the species is flourishing in the Orontes river in the Bekka Valley. The area is home to around 150 trout farms, which employ1,000 people, making fish breeding the biggest agricultural sector in the area. This article is a great overview of how the industry works in Lebanon. Read more...
  • Ocean acidification is of major concern to shellfish farmers in Washington state, USA. Increased levels of CO2 damage shellfish shells, threatening the industry. A state report into the issue highlights that Washington must think globally— pressing with partners abroad and at home for a strategy to reduce carbon dioxide emissions — and act locally by acting to cut down agricultural chemicals, storm-water and waste-water runoffs going into the state’s marine waters.   Read more...

(The Daily Star :: Lebanon News :: http://www.dailystar.com.lb)
While not native to Lebanon, or the region, freshwater rainbow trout can be found in abundance at the headwaters of the Orontes river, in the Bekaa Valley.
The Lebanese section of the river stretches some 25 km from its source, close to Hermel, to Lebanon’s northeastern border with Syria, and it has become the top site in the country for raising the fatty fish, as the water there is deep and relatively clean.
The Orontes is the fastest flowing river in the country, with an average of around 660 cubed meters of water flowing every minute, and the temperature is also the most suitable for raising trout, ranging between 12 and 16 C. This unique water environment in Lebanon is ideal for the species, which only lives in flowing water that is deep and clean.
There are around 150 fish breeding farms along the Orontes basin, providing the only source of income to over 300 families and more than 1,000 jobs – from supervising the farms, raising the fish, transporting them to markets to distributing them to shops.
Annual production ranges from 1,000-1,500 tons, with the price of a ton at around $4,000.
Agricultural engineer Malek Nassereddine says that fish breeding is the biggest agricultural sector in the area of Hermel, and that trout might in the future be the major product produced in the area, as the conditions there are so ideal for the fish, which would help boost the economy of this poor and underdeveloped area.
