Novus World Aquaculture Society (WAS) Internship programme winner announced

João Manuel Cura Rito from Coimbra, Portugal, has won the Novus World Aquaculture Society (WAS) Internship.

As part of his prize, João, 29, will travel to Vietnam to take part in a four-week internship in summer 2014. João will work with The Novus Aquaculture Research team on a current project being carried out at the Novus Aqua Research Center in Vietnam. The Novus Aqua Research Center is integrally connected to the aqua industry and will allow the intern to learn about and experience aquaculture in Vietnam through interactions with the Novus research and operations teams.

João completed his undergraduate studies at the University of Coimbra with an emphasis in ecology. He continued there completing his masters in the area of estuarine ecology. His research focused on the population dynamics in extreme climate events of a bivalve species present in Mondego estuary, Portugal. After finishing his masters degree, João was hired to participate in grant funded environmental research at a commercial aquaculture company on the coast of Portugal. This exposure to aquaculture catalyzed his interest in the field. An opportunity was presented to continue studies towards a PhD degree in biosciences at the University of Coimbra in biochemistry with a specialty in aquaculture. The work aims to optimise diets for farmed sea-bass through metabolic profiling. The research is grounded in fundamental aspects of biochemistry and metabolism, tools which João has enthusiastically embraced with the goal of bridging nutrition back to principles of aquaculture and ecology.

His internship challenge proposal is entitled “Glycerol as a Novel Feed- stock Supplement for Sparing of Dietary Protein Catabolism and Thus Reducing Feed Cost”. The proposal is described as an evaluation of the feasibility of inclusion of glycerol byproducts from biodiesel production in fish diets with the application of biochemical methods for estimating whether the contribution from glycerol reflects the sparing of gluconeogenic amino acid catabolism.

João is excited about the opportunity to explore Vietnam, meet new people and learn about the aquaculture industry there. He is looking forward to working with Novus scientists. “The chance to exchange ideas with top scientists in the aquaculture research area is something that not all students in the beginning of their PhD have the privilege to do and I am very excited to start this summer!”

28/02/13: Vietnamese shrimp exports expected to fall; four new salmon farms in New Zealand; mislabeling seafood

Shrimp exports from Vietnam are expected to drop by up to 13 percent in the first quarter of 2013 according to the Vietnam Association of Seafood Exporters and Producers (Vacep).
A report by the association said that Vietnam is expected to earn roughly $1.15 billion from seafood exports in Q.1, lower than $1.32 billion during the same period last year. Vacep's forecast is based on the declining seafood production and processing in the first two months of the year, with the key products as tra fish and shrimps.

Four new New Zealand King Salmon farms have been approved at Marlborough Sounds, New Zealand which comes as welcome news for Aquaculture New Zealand. Aquaculture New Zealand Chairman Peter Vitasovich said the farms would create permanent full-time jobs and provide significant downstream benefits for associated industries while generating export earnings through the sustainable production of premium seafood.
“Four new working salmon farms in the Marlborough Sounds will provide valuable employment opportunities within the community, while also attracting skilled labour to the region, to work across the spectrum of production – from farming to processing to marketing and business roles,” says Vitasovich.

Mislabeling of beef products has caused a stir in the United Kingdom. Now there are similar concerns over the labeling of seafood in the USA. A report by conservation group Oceana into the issue of seafood fraud has found that a third of 1,215 samples collected were mislabeled. DNA tests found that the main culprits were snapper and tuna which had the highest mislabeling rate of 87 percent and 59 percent, respectively.

27/02/13: Life insurance for fish; Alaskan government vetoes GM; new BAP standards

The Insurance Board, the insurance sector regulator in Nepal, has finalised a policy on fisheries insurance that will make it mandatory for all non-life insurance companies to provide coverage to fishes grown in ponds of at least 200 sq m.
The measure will protect fish farmers in case of damages or losses of their products and encourage banks and financial institutions to provide credit for the industry.

The Alaskan House of Representatives has come out in opposition to GM fish. Representatives unanimously approved House Joint Resolution 5 which urges the US Food and Drug Administration to reconsider a preliminary finding that genetically modified fish would not significantly impact the environment. The resolution asks for labeling for GM salmon, if the product is ultimately approved.

The new Best Aquaculture Practices (BAP) standards for finfish and crustacean farms are set to go live in spring 2013. The revamped standards come following a 60-day public-comment period which included contributions from from fish farmers, academics and NGOs from Australasia, Asia, Europe and America.
Changes include greater emphasis on social responsibly and will apply to all types of production systems for finfish and crustaceans, excluding cage-raised salmonids, for which separate BAP farm standards exist.

Event: Aquaculture 2013 review

With over 3,000 delegates and more than 350 presentations in 15-minute bite size chunks each over four days, Aquaculture 2013 in Nashville, Tennessee, USA, has closed after being hailed a great success by its three independent organisers: the World Aquaculture Society, the National Shellfisheries Association and the Fish Culture Section of the American Fishieries Aquaculture Society. 

Held in the Nashville Congress Centre, Aquaculture 2013 also hosted a very successful three-day exhibition during the four days of presentation running from last Friday to its Monday close.

This meeting will be noted for its keynote opening presentation delivered by Dr Edward Allison on ‘Aquaculture in a Changing Climate’. 

Dr Allison who has worked with the UN Food and Agriculture Organisation in West and Central Africa and until recently the director of policy, economic and social science research programme at the World Fish Center in Penang, Malaysia, suggested aquaculture was being overlooked in discussions on climate change. His research bridges economic and social development concerns with those of fisheries, aquaculture and environment governance.

His current work focuses on the contribution of fisheries and aquaculture to food and nutrition security with aspects of adoption to climate change. In September 2013 he will take up a professorship in the School of Marine and Environmental Affairs at the University of Washington in Seattle.

He told delegates that feed manufacturers should be congratulated for the work they have been doing to make aquaculture viable through their development of efficient and effective ration formulation.

During the same opening session and among the various awards was a joint presentation of WAS Exemplary Service Awards made to its general manager John Cooksey and his wife Mary. Both were honoured for their work organising WAS activities since 1996.  Kevan Main, President World Aquaculture Society 2012-2013, presented the award to the acclaim of the audience – the first time a join award had been made.

“I was taken completely by surprise,” John told International Aquafeed following the presentation. He recalled the first meetings he organised for WAS, the first in San Diago, California, prior to being invited to join the Society and take over all its meeting. The second his first international meeting for WAS in Thailand in 1996.

“Organising conferences has been getting easier but the scope of each is getting wider with meetings being held all over the world. Some locations in the beginning had no facilities at first including no pipe-and-drapes and where catalogues went handmade. But they were a lot of fun,” he recalled.

26/02/13: EU discusses discards; Yukon fisheries management; US shellfish bill gathers pace

Members of the European Council are currently in Brussels, Belgium debating reform to the common fisheries policy. Top of the agenda is proposed changes to the discards ban. You can watch the proceedings live here.

The American Fisheries Society has released a report into improving fisheries management in the Arctic-Yukon-Kuskokwim region. Fisheries management in this region is extremely challenging due to the mixed stock origin of most fisheries, remoteness, complexity, and vast size of the major river drainages, U.S./Canada Treaty agreements for the Yukon River, and the interdependence of subsistence and commercial fisheries. The proposed projects would provide necessary research and support management activities within the region.

The House of Representatives Agricultural and Natural Resources Committee in the USA has approved a bill to address the concerns of shellfish producers. The bill addresses to key areas of concern in the industry including the need for new research in the light of rapid changes in shellfish farming practices and the environmental impact of shellfish farming.

23/02/13: Japanese aquaculture restaurant; Canadian government promotes prawn industry; Marine Harvest apprentice

An aquaculture restaurant run by Kinki University, Japan is set to open its doors to the public in April 2013.The Osaka-based eatery will specialise in blue-fin tuna and other fish raised from eggs at its aquaculture facilities. The aim of the restaurant is to popularise farmed seafood in stores on a scale equivalent to commonly available meats.

The Canadian government and the Canadian Association of Prawn Producers have joined forces to promote prawn exports. A $165,000 marketing campaign has been devised to draw attention to cold-water shrimp in countries including China and Russia.

The first aquaculture apprentice at Marine Harvest, Scotland has started work. Sixteen-year-old Ross MacDonald from Fort William beat off stiff competition to work at Scotland's largest aquaculture company.  MacDonald will works across a range of departments, receiving training on boat handling, fish health, feed management and finance.

22/02/13: Salt tolerant plant for aquaculture use; AKVA acquisition; research into salmon virus vaccines

Researchers at Murdoch University are investigating the uses of a salt tolerant plant in both aquaculture and agriculture. The saltgrass, Distichlis spicata is very effective at removing salt from water.

AKVA Group has bought 70 percent of the shares in Plastsveis AS for a price of NOK 20 million.  90 percent of the purchase price will be paid in cash on completion. The remaining 10 percent will be paid six months after the transaction is completed. The transaction is subject to final approval from the Norwegian competition authorities and is assumed to be completed mid March 2013, with operational effect from January 1, 2013.

The Research Council of Norway's Platform for Viral Aquaculture Medicine is getting closer to developing a much-needed vaccine against ISA and IPN in salmon. Researchers have been studying how these viruses side step the salmon immune system and which immune response may provide protection against diseases.

21/02/13: news stories from the Philippines, Australia and Scotland

A fish forum in the Philippines has discussed the potential of pangasius aquaculture. Local farmers, Municipal Agriculture Officers, and businessmen of Rizal province recently attended Department of Trade and Industry (DTI)-Rizal’s Investment Opportunity Forum on the fish called pangasius Antipolo City.
Romy Pol of the Bureau of Fisheries and Aquatic Resources – National Inland Fisheries Training Center briefed the attendees on the characteristics and history of pangasius.
According to Pol, pangasius comes from the family of the catfish and originates from the Mekong River which runs through China, Myanmar, Vietnam, and Thailand. The specie is very hardy and lays around 50,000 eggs. However, studies show that pangasius only lays eggs in the Mekong River and must be induced to lay eggs in other habitats or fishponds. The fish also only reach sexual maturity after two to three years. BFAR also reiterated that pangasius are only allowed to be bred in inland fishponds in the country.

The team at AM, one of Australia's most popular radio shows, is into all things aquaculture at the moment. The team is on the Gold Coast reporting from Australia's largest tiger prawn farm.

The Scottish Salmon Company has submitted plans for a new farm site at Reibinish with the potential to farm 2,000 tonnes of salmon the application is one of three being considered by the Scottish based and operated salmon farming company for Harris.

IAF interview: Torben Svejgaard, chief executive officer, BioMar Group, Denmark

Born in 1955, Torben Svejgaard is chief executive officer of the BioMar Group, headquartered in Denmark. At 57 years he is an economist with close to 30 years’ experience in B2B businesses with the first 25 years in the food ingredient area. From 1985-1991 he was marketing assistant and marketing manager at Aarhus Olie - speciality vegetable oil products and soy protein concentrates.
Then from 1991-2008 he held different upper management positions within Danisco (now Dupont), a world leader in functional food ingredients plus biotech products for feed, biofuel and technical purposes.
From 2004-2008 member of Executive Committee, that is the top management team of the company. Since 2008, he has been Group CEO of BioMar, one the biggest fish feed producers with a turnover in excess of €1 billion in 2012.

Will farming other species of fish follow the salmon example?
In my view, there is no doubt that fish farming will become more and more professionalised over the coming years. And it needs to if demand is to be met in a sustainable way as well as in a cost-efficient way.
You can see this happening for other species not just from a feeding point-of-view but also in farming. But it would be fair to say salmon is where there has been the greatest progress and where professional farming has been taken the furthermost. Let me add that this doesn’t mean that salmon is a superior fish!
Other species will follow but at different speeds and in different ways.
Tilapia in the USA for example, has developed two distinctive markets – a frozen market, primarily supplied by China, and a fresh market supplied mainly from Central plus the northern part of South America. As a result tilapia now has two different market prices and two sets of demands being placed on it.
With a further professionalism of fish framing demands to fish feed suppliers will also increase, and we feel in BioMar that we are well prepared for that.

Carp is a widely consumed fish species in China. Is carp likely to challenge fish species in western/developed countries?
I don’t think so. Based on my experiences from the food ingredient industry, people are conservative about their food products choices and I would be very surprised if carp, which is a quieter species than other, became a more commonly consumed fish in developed countries.

Would that decision have anything to do with a fish species being a herbivore or a carnivore?
Herbivores are by far the largest portion of fish species in the world while carnivores are in the minority. However, the future direction for demand will not be dependent on whether a fish species is herbivore or carnivore but whether the consumer likes the fish in question and to what extent we can develop a cost-effective production system for that species to meet growing demand.
Comparatively, we have many different species of fish being farmed today – when compared to chicken and pigs. There is a clear need to choose those species that can be grown in a cost-efficient way.

Does that mean fish has to be cheaper than chicken in the consumer’s eyes to increase demand?
While in some supermarkets you will find fish cheaper than chicken, the difficulty of the comparison is to understand the cost of protein ratio between the two protein sources. A relative price might mean something, but this is not a mathematical choice in the eyes of the consumer. The consumer - at least the ones with a certain income level - is not asking, “Should I feed my family on chicken or fish this evening?” and basing that choice on what the price comparison is.
While, chicken is also very efficient in converting feed into protein, fish is generally more efficient. With rising commodity and protein prices in our raw materials the relative cost advantage of fish over chicken will increase.
I think it’s important to understand that consumers do not based their buying decision on price alone despite the cost efficiency achieved in the production process greatly influencing the price of the end product. Most shoppers buy fish because of the virtues of fish in itself, not because it’s cheaper than chicken.

There is much discussion about achieving a production breakthrough one kg of fish protein from one kg of feed. Is this a fair objective or is reducing the use of fishmeal in diets a more critical issue?
Feed conversion is not about achieving 1:1, but about the retention of energy and protein by a fish species that gives it its efficiency. Assessment based on kg in and kg out is a little artificial.
On the question of fishmeal, the salmon industry, for example, is a net fish protein producer – we have reduced protein fishmeal in diets to between 10-15 percent down from 30 percent over time an extended period of time. However, that’s not the goal in itself. If we take responsibility-sourced fishmeal and fish oil then we can make an upgrade from other materials that would not have been sold as food products – otherwise these products would have been wasted. That’s a rational objective for our industry and we should try to demonstrate that to consumers.

There’s much talk about the challenge of feeding nine billion people on the planet by 2050. Will fish play a central role in meeting this challenge?
Fish will play a role in feeding the nine billion people by 2050. And this should be one of the roles of professional fish farming, but we must also realise that this is only possible, if the industry does it in a sustainable way both from a broad environmental point of view and from an economical point of view. If the industry does not make sufficient profit, the needed growth will not happen. But farming can contribute to saving the world. We all know our industry can do that.

20/03/13: Australia special

There's a bit of a buzz about cobia at the moment. The species is being earmarked as 'the next big thing' in aquaculture thanks to its quick growth and firm flesh. One farmer keen to explore the potential of the species is Alistair Dick, of Pacific Reef fisheries, near Ayr, Australia.Dick told ABC Rural that the financial potential for fish farmers is significant considering cobia can grow up to 10 kilograms within their first year - double the speed of barramundi and triple the speed of Atlantic salmon.
If you're a cobia fan, look out for the next issue of International Aquafeed has a cobia expert topic.

There are successful fish farms in South Australia, Tasmania and Western Australia and now there are plans for a farm in New South Wales. However, the proposal to build a farm four kilometres off the Central Coast is running into trouble. Aquaculture advocates argue that the New South Wales Fisheries Institute farm will take the pressure off wild fish stocks while other believe the farm will be a polluter.

PIRSA Fisheries and Aquaculture has released a proposal to introduce snapper spatial closures for public consultation.
The proposed spatial closures encompass several snapper spawning aggregation sites within Spencer Gulf and Gulf St Vincent, which would be closed to Snapper fishing between November and January each year, when Snapper are known to aggregate in South Australian waters. This is a temporary management measure that would be reviewed on an annual basis.

19/02/13: Aquaculture in Kenya and seafood production in New Zealand

Kenyans may be about to enjoy more fish suppers. Aquaculture production in the country has increased by more than 500 per cent in the last four years, according to the ministry of Fisheries Development. Production stood at 4,220 metric tonnes in 2008 before shooting to 22,000 tonnes in 2012.

One of New Zealand’s largest seafood companies is coming to Cawthron Aquaculture Park, near Nelson.
Aotearoa Fisheries Limited will take over and expand Cawthron Institute’s commercial oyster nursery and spat growing operation at the Cawthron Aquaculture Park. Cawthron Institute will continue to produce and supply oyster larvae to industry.
“Cawthron Institute has developed a scientific selective breeding programme for oysters over the last ten years,” says Ian Kearney, chairman, Cawthron Institute. “Three years ago we established the outdoor nursery to grow and supply increased volumes of selectively bred spat to the industry.”
“It is now appropriate to allow our industry partners to take over this expanding spat production activity and for Cawthron Institute to focus its expertise on scientific research for the aquaculture industry.”
Cloudy Bay Clams, New Zealand is celebrating after being given Friend of the Sea international sustainability seal of approval. The audited fishing vessels for storm clam (Mactra murchisoni), diamond (Spisula aequilatera) and moon shell (Dosinia anus) and Tua Tua (Paphies donacinia), were found to be compliant with all Friend of the Sea criteria for sustainable fishery.
The clams are harvested from a sandy substrate along the coastline. The fishing method is based on a hydraulic winnowing clam rake, designed and developed by the company itself. The Clam Rake mesh is 10mm Dia and no nets are used.
The use of water jets is designed to maximize catch, minimise mortality of clams and minimize the effects of dragging the dredge through the sand. The only by-catch is the occasional paddle crab which represents less that less than 1% of the catch. If alive and unharmed, they are returned to sea.
“Friend of the Sea certification confirms our efforts and continuous commitment to sustainability" explains Mr. Mike Ponder,  general manager, Cloudy Bay Clams “and it represents an important added value for our product”.

Switch the Fish campaign a big success for Scottish mussels

Save the Fish campaign [Credit: The Drum].

Rope grown mussels from the Scottish Shellfish Marketing Group (SSMG) enjoyed a great reception from consumers during Sainsbury’s recent ‘Switch the Fish’ campaign.

During the initiative, the supermarket gave away free samples of less popular types of seafood to anyone who bought one of the ‘big five’ eating varieties of cod, haddock, tuna, salmon and prawns. Scottish rope grown mussels was one of the alternative types of seafood selected for the free sample give-away, and according to Rob Mitchell of SSMG, they went down a treat with shoppers.

“The Switch the Fish campaign was a great success and it really highlighted to consumers the fantastic taste of mussels and their simplicity in cooking,” he says. “The feedback we have had from Sainsbury’s was very positive and we are hopeful that this campaign will have played an important role in ensuring that consumers broaden their horizons when purchasing seafood.

“We are particularly proud of the sustainability credentials of our Scottish rope-grown mussels, which also seems to appeal to consumers.”

SSMG mussels are independently certified by both the Marine Stewardship Council and the Friend of the Sea for the environmentally-friendly manner in which they are grown.

12/02/13: 'Super chilled' fish; knife fish infestation; rooftop aquaponics in India

Ice is the no-brainer way to keep fish fresh during transportation. However, scientists at Nofima, Norway believe that ice and insulated boxes create a false sense of security and restrict innovation in the sector.  According to the feed research institute, in 2010 Norway exported 922,000 tonnes of salmon – the vast majority of this packed fresh in polystyrene fish boxes with 5–6 kg of ice per approx. 22 kg of fish. This is equivalent to 7,500 articulated lorries full of ice (around 230 million litres of water).
Nofima has been working on alternative methods for transportation of fish including 'super chilling'. 
This method involves reducing the temperature down to the equalisation temperature of the fish, typically -1 to -2 °C. Super chilling is the easiest way of increasing the primary quality period of the fish and may be combined with packaging in a protected environment of carbon dioxide and nitrogen, during both distribution and in consumer packaging. This enables high quality to be maintained for several weeks in a cooling chain that is in accordance with the regulations (0 to +2 °C).

Aquaculture operations in Laguna Lake, The Philippines are under threat from an infestation of knife fish. Over 5,000 fishers in the lake have been affected while municipalities have also reported knife fish problems.

The Bureau of Fishery and Aquatic Resources – National Inland Fisheries Technology Center (BFAR-NIFTC) and local governments are currently undertaking mass retrieval operations to address issue. 
The collected knife fish will then be turned over to BFAR for the development of technologies for its economic utilisation.

11/02/13: Salmon special: equipment and escapees; ISA; Marine Harvest

Equipment failure is the reason behind more than two thirds of salmon escapees according to research conducted by the SECURE project. The study, which analysed all escape incidents from salmon farms in Norway from 2006 to 2009, found that faulty nets and cages were the main cause of 68 percent of fish escapes. 

Earlier this year, the Canadian Food Inspection Agency (CFIA) allowed salmon infected with ISA from a Cooke Aquaculture farm in New Brunswick to be processed. This decision was controversial in the aquaculture community as it was first time the agency had given permission for fish with the disease to be processed for market. 
However, that's not where the story ends. Now, various restaurants and  in have refused to serve or stock fish infected with the disease.

Integrated rice-fish farming is the need of the hour says, the Financial Express, Bangladesh. Although rice production is well-established in the country, fish farming lags behind. However, around 10.14 million hectares of rice fields, there is scope to integrate fish production and rice farming. In addition to increasing fish production, combined rice-fish production can also improve productivity and profitability of rice farming.

07/02/13: FEFAC welcomes PAPs in EU; algae as a fish feed ingredient; small-scale fisheries and 'wellbeing'

FEFAC President Patrick Vanden Avenne welcomed the European Commission decision to adopt and publish the new regulation on the reauthorisation of non-ruminant processed animal proteins exclusively for use for fish feeding. He stated that “this measure paves the way for our EU aquaculture producers to step up their efforts to encourage the sustainable development of EU aquaculture by creating a level playing field with seafood imports from third countries”.
“EFSA has provided clear scientific evidence that non-ruminant PAPs produced in accordance with the high EU processing standards are safe. They can help in reducing the EU dependency on fishmeal imports thus contributing to the Common Fisheries Policy reform goals of pairing sustainable wild fisheries with the sustainable development of aquaculture”.

He highlighted that "the European feed industry is fully committed to support the competitiveness and sustainability of aquaculture production in the EU, as set out in the Commission proposal on the Common Fisheries Policy and supported by the EP Committee on Fisheries in their December 2012 vote on the CFP report of MEP Mrs Ulrike Rodust”. The new measure contributes to global food security, by reducing the EU dependency on seafood imports which account for more than 70 percent of the current EU consumption". He noted that PAPs are widely used by aquaculture producers in Asia and North- and South-America, who are exporting farmed fish to the EU.
Look out for an article on PAPs and aquafeeds in the next issue of International Aquafeed.

There are many studies looking at the feasibility of using algae as a fish feed ingredient on a wide scale. One such company is OriginOil which has joined forces with Pennsylvania-based aquaculture company, WeFeedUs, to test and validate OriginOil’s proprietary water decontamination and algae harvesting technologies for aquaculture systems. 
In lab tests, OriginOil researchers used a lab-scale SOS system to process water with total ammonia content of approximately 30 parts per million , more than a dozen times the limit for optimal fish production. The process reduced this high ammonia content to less than 0.25 ppm in three minutes without the use of chemicals, or more than a 99 percent reduction.

A new document published by the World Fish Center examines the small-scale fisheries through the concept of 'wellbeing'. Despite recognition that small-scale fisheries make  contributions to economies, societies and cultures, assessing these contributions and incorporating them into policy and decision-making has suffered from a lack of a comprehensive integrating ‘lens’, say the authors. 
The paper focuses on the concept of ‘wellbeing’ as a means to accomplish this integration, thereby unravelling and better assessing complex social and economic issues within the context of fisheries governance.
