20/07/2017: Innovation never sleeps: The power of C-Dome technology

by Nina Hanssen, Commercial Director of Aqua Farming Solutions B.V., a subsidiary of H2O Technics B.V., The Netherlands

As the key industry that needs to ensure the ever-growing world population will have sufficient food on the table in the future, the aquaculture industry has a huge burden upon its shoulders

Fish consumption is growing rapidly, not only due to better availability, but also since consumers are becoming more and more aware of the health advantages of seafood. There is no reason to believe that this will change, but fish farmers all over the world are preparing effectively for the necessary adjustments.

Although parts of the industry might still have a long way to go before it is sustainable in the eyes of a fairly big part of the consumer market, there is no doubt that within the industry itself, there is a fast-growing awareness of the importance of sustainable and environmentally friendly farming, as well as increased efforts to meet the requirements of the consumers.

Today’s aquaculture industry is young, and it stands to reason that it still has a few issues that need better solutions, including the continuous problems caused by parasites which not only has an impact on wild fish like trout and salmon, it also disaffects public opinion towards farmed fish around the world.

A vast amount of money is being spent globally every year to continue to improve all aspects of aquaculture, and the will to find solutions to problems, is enormous, giving credit to the entire industry as a whole as the efforts and self-appointed targets are consequently raised. For example, new techniques and ideas are invented, developed and tested, and existing techniques improved where possible.

Finding one method which can solve all issues is the ultimate goal for everyone involved in aquaculture, and as the whole industry goes through a continuous development and is strong enough to face any new challenges, there is no doubt that aquaculture will sooner or later succeed in finding that one method. Indeed, we might be closer than we realise.

A new technology, a natural solution
The technologies of H2O Technics B.V. was developed by a team of Dutch inventors more than 12 years ago, and although it was based on an already known technology, the Dutch inventors were able to reinvent and customise the technology for various purposes related to water treatments.

Similar technology is used in several areas of everyday life; pregnancy ultrasound, echo sounding to determine depth of water, automatic door openers, processing of liquids and paper, cleaning of medical equipment; the list is endless. The C-Dome has been developed by Aqua Farming Solutions, for and together with the aquafarming industry, and it is equipped with four resonators mounted on the inside, three aiming sideways and one aiming straight down.

The C-Dome is preferably placed in, or close to the middle of, the fish cage and each resonator has a reach of approximately 50 meters in salt water. Together with the electronics box mounted on the frame, each resonator is able to create non-inertial Nano-cavitation: The microscopic vibrations caused by the resonators, change the potential energy stored within the mass of water into kinetic energy, creating microscopic voids in the water which implode due to the pressure changes, hereby creating microscopic water jets; Nano-cavitation.

Our Nano-cavitation is unique within water treatment, and as mentioned earlier, is the result of more than 12 years of reinventing the ultrasound technology. It has been in use for several years already in the Netherlands, and together with the multiple installations in fish cages in several countries, the technology has proven its worth.

The importance of keeping the nets used in the fish cages clean and free of algae, is probably something the average consumer hasn’t really thought of, but for the farmer, it is of utmost importance. Bio-fouling might not seem to be a big issue, but too much of it can lead to far bigger problems; the nets may become too heavy, followed by the risks of tearing which again may give the fish the opportunity to escape, with all the consequences that this entails.

The accumulation of fouling organisms on the nets may lead to hydroids settling down, in addition to being a perfect hiding place for various ectoparasites like sea lice and the amoeba Neoparamoeba perurans; the last one causing the amoebic gill disease in farmed fish. There are several ways of cleaning the nets, and pretty much all of them include handling the fish one way or the other, which by multiple treatments may have impact on the skin and the mucus layer.

High pressure and mechanical net cleaning may also lead to damages on the net itself, increasing the risk of escapes, as well as release of various organisms hiding in the fouling which may even expand the problem further with regards to parasites.

“Being close to our customers and interacting with leading experts in key aquaculture markets is part of our strategy as we are increasing our footprint in the industry. It promises to be a busy summer,” says Dr Peter Coutteau, Business Unit Director Aquaculture for Nutriad.

“Our sponsorships focus on supporting the aquaculture sector in general, and more specifically South East Asia, to help producers deal with the key challenge of reducing the impact of diseases and parasites on productivity.”

Asian Pacific Aquaculture (APA) 2017, the major aquaculture exhibition in South East Asia organised by the World Aquaculture Society, takes place Kuala Lumpur from 24th to 27th of July. Nutriad sponsors the scientific session entitled “Functional Feeds for Disease Prevention.”

At this session, chaired by Dr Peter Coutteau and Professor Dr Rossita Shapawisurely, speakers from the industry as well as the academic sector will treat some hot topics related to Health management and farm practices in Thailand, functional feed additives to prevent fish and shrimp diseases, effects of soybean meal on tissue cholesterol status and molting relative gene expression in white shrimp as well as effects of garlic against Aeromonas hydrophila in Nile Tilapia.

“We carefully selected the speakers and topics for this Nutriad sponsored session, allowing our partners and customers in APAC to learn about current market developments and new findings regarding health management,” stated Allen Wu, Regional Manager Aquaculture APAC and Board Director of World Aquaculture Society – Asian Pacific Chapter.

Nutriad will also organize a gala diner upon invitation. The Aquaculture Roundtable Series (TARS) 2017 is built around central them of Finfish Aquaculture: Strategies for Growth. This is the second time this series of roundtables, initiated in 2011, is focusing on the finfish aquaculture industry. The meetings will take place in Bali, Indonesia from August 16-17 will explore the growth potential of Asia’s finfish aquaculture industry.

Nutriad proudly has been sponsoring TARS since 2012. This year, the company sponsors Professor Dr Francisco E. Montero from the University of Valencia, Spain to speak on Parasites Prevention in Fish Farming.

“Parasite control is one of the key issues in health management of all commercial species of fish, including salmon, tilapia and marine fish. However, there is a general lack of basic knowledge on fish parasites in the aquaculture industry, particularly in Asia,” according to Dr Maria Mercè Isern Subich DVM, Nutriad’s Business Development Manager Aquaculture Health.

“Professor Montero, involved in research on fish parasitology since 2001, will share his views on the life cycle and mode of action of different species of fish parasites relevant for aquaculture, and illustrate current practices and challenges to prevent and/or treat parasites in fish farms in Europe.”

The 10th Diseases in Asian Aquaculture (DAA) conference will be organized by the Fish Health Section of the Asian Fisheries Society (FHS-AFS) in Bali, Indonesia from Aug 28 to Sept 1. FHS-AFS was founded in 1989 in Malaysia and made a tradition of this triennial scientific symposium to update members and aqua health professionals on topics related to aquatic animal health in Asian aquaculture.

DAA10 central theme will be “Enhancing Aquatic Health Research and Services through Public-Private Sector Partnerships” and anticipates the attendance of 500 delegates from 30-40 countries. Nutriad is a silver sponsor at DAA10 and Dr Maria Mercè Isern Subich DVM will give an overview of recent trial results obtained with Nutriad’s health program in lab and field trials during an oral presentation entitled “Functional feed additives as prevention of parasitic disease in fish”.

Nutriad delivers products and services to over 80 countries through a network of own sales offices and distributors. Supported by four application laboratories and five manufacturing facilities on three continents.

19/07/2017: Sustainable farming of lobsters: A dream soon to become a reality?

by Associate Professor Greg Smith, University of Tasmania, Director of the ARC Research Hub for Commercial Development of Rock Lobster Culture Systems at the Institute for Marine and Antarctic Studies (IMAS)

Spiny lobsters, also known as rock lobsters in Australia and New Zealand, are one of the few high value marine species that are yet to be cultured in commercial hatcheries
The appeal of culturing spiny lobsters is due to favourable market attributes including the fresh product’s high value in the Asian market, increasing product demand and the static nature of current wild fishery.

Image credit: IMAS

Research into the biology of spiny lobsters is not new, with initial propagation studies undertaken in Japan in the 1800s. The larval phase of up to seven species was completed in Japanese laboratories between 1960 and 2000.

Spiny lobster propagation research has since been undertaken in a number of countries including Australia, New Zealand, Vietnam, India, America, Mexico and England. For the last two decades, larval propagation research has been focused in Australia and in recent years at the University of Tasmania’s Institute for Marine and Antarctic Studies (IMAS), in Hobart.

Australian lobster research has had long-term government support through the Fisheries Research and Development Corporation (FRDC), the Tasmanian Government, the Australian Research Council (ARC) and private equity.

The current research program at IMAS focuses on commercialisation of the hatchery technology supported by an ARC grant of US$5 million through the Industrial Transformation Research Program.

The ARC funding targets collaborative research between industry partners and Australia’s best researchers. The ARC Research Hub for Commercial Development of Spiny Lobster Culture Systems is a collaboration with the University of Tasmania, University of Auckland (New Zealand), University of the Sunshine Coast, and Australian industry partner Plastic Fabrications Group.

The research programme is supported by the Tasmanian Government through the Sustainable Marine Research Collaboration Agreement. While there have been challenges to overcome in the hatchery production of seed stock, the grow out sector has been established since the 1990s, primarily in Vietnam, with some recent activity in other countries in the region including Indonesia.

Despite the larval phase of many species of spiny lobster being completed in research laboratories, until recently, there has been a failure to translate the small-scale research success into commercial processes.

As a result of there being no hatchery production of spiny lobsters seed stock, aquaculture is based on the collection of wild seed stock. The larval cycle of spiny lobsters is protracted; typically females mate in inshore waters and carry a fertilised bundle of eggs externally attached under their tail.

While attached to the female the eggs develop for a period of between weeks and months, depending on the species, and then hatch as underdeveloped larvae (phyllosoma). To sustain a static population, spiny lobsters focus their reproductive energy in the investment of large numbers of offspring.

In the wild, each breeding female will hatch millions of phyllosoma, but with a long larval duration, small numbers survive to reach juvenile and later adult stages. Phyllosoma reside within the water column and are transported into the open ocean by currents and eddies, they have very limited swimming ability.

In offshore waters, and often at depth, the phyllosoma will undertake the complex larval development phase, including up to 24 individual moult events. The larval duration can be protracted and may last anywhere between months to years, dependent on a number of factors including the species, availability of feed and environmental conditions.

At the completion of the phyllosoma phase of development spiny lobsters undergo an extreme metamorphosis event, transforming from a two-dimensional clear disc shaped phyllosoma into a three-dimensional shaped puerulus.

This puerulus is a non-feeding nektonic stage; the primary purpose of this life-phase is to swim from the offshore waters to inshore reef systems or other suitable benthic habitats to settle upon. This migration from oceanic waters to reef habitats during the puerulus phase is often a distance of hundreds of kilometres.

When they have reached a suitable habitat puerulus will undergo a final larval moult transforming into the benthic juvenile phase and assume typical lobster morphology. Currently, aquaculture farmers will target both of these latter stages of development to enable the stocking of their sea cages.

Puerulus are caught at night in inshore bays using lights for attraction into fine mesh nets, or alternatively harvested from artificial settlement structures, such as bundles of mesh or used cement bags.

The juvenile development phase is also targeted using poles with small holes drilled in them set near the shoreline; this structure provides a habitat for juvenile lobsters to shelter in and thus a means of collection for farmers. The preferred culture species targeted in Vietnam is Panulirus ornatus, also known as the tropical, ornate or painted lobster, however obtaining this species from local waters can be difficult, with other less commercially desirable species also being collected and cultured.

There are a number of issues with the reliance on collection of seed stock from the wild, including sustainability, reliability of supply, biosecurity and the inability to obtain genetic improvement of cultured stocks.

The long and complex lifecycle of spiny lobsters has provided challenges for the establishment of a sustainable commercial aquaculture industry. The collaboration between expert scientists and industry in the ARC Research Hub for Commercial Development of Spiny Lobster Culture Systems has provided the platform for innovative research to bring the dream of sustainable farming of lobsters a step closer.

18/07/2017: Royal honour for aquaculture innovation, Norway

Karsten Glomset is well-known to all who have worked with oxygenation in aquaculture

Recently, he received the King’s Medal of Merit for his pioneering work. His employer through many years, AGA AS, is participating in the Aqua Nor seminar, ‘Modern aquaculture – more than salmon’, and their presentation is built on Mr Glomset’s pioneering work through 30 years.

A humble recipient of honour
AGA is a well-known and large gas company and among the market leaders in oxygenation in Norway and Northern Europe. The group is very pleased with Mr Glomset’s role in positioning the company in the aquaculture industry – but Mr Glomset returns the compliment, “I have no idea why just I am honoured with this medal. What we have done here is a team effort and an excellent example of cooperation across various divisions in the company,” he said in a recent interview.

The past is important to the future

Although both AGA and the rest of the industry has developed new technology continuously through the years, Mr Glomset’s contributions have been indispensable to all who have continued his work. He has patented several solutions, which have led to a situation where we can now raise robust salmon in healthy environments of growth.

Already in the 1980s Mr Glomset laid the foundation for oxygenation which made it possible to improve production of smolt in close tanks on land and maintain an oxygen-rich environment during operations that may be stressful to the fish. In a ceremony at AGA’s plant in Ålesund, Mr Glomset was honoured for his work with one of Norway’s highest honours, the King’s Medal of Merit.

AGA participates in a seminar at Aqua Nor
In the seminar «Modern aquaculture – more than salmon», which is organised by the Nor-Fishing Foundation and Innovation Norway, AGA will bring over 30 years of experience with oxygenation to the audience as a backdrop for modern innovation and the latest expertise. AGA’s presentation will focus on future sustainable oxygenation for the aquaculture industry.

Show up in Hall A4 at 14:00 hrs on Tuesday 15th of August 2017 and be part of this exciting seminar.

A detailed programme will be announced soon.
