Editorial

Welcome to our October issue of Aquaculture Scoop.

In this issue we look at Nets and cages and give you an insight into some up-coming events for you to consider.

In Trondheim, Norway the world’s largest aquaculture trade show AquaNor took place from August 13 – 16. Attended by 480 exhibitors, with over 18,500 visitors from 65 countries. NISA Media was there at the show at stand V620, to meet companies from all over the world involved in the aquaculture industry.

Our news editor Martin Little said the show was a huge success, with companies such as BECK Engineering’s who won the Aqua Nor innovation award at the exhibition, with their Stingray project a revolutionary new technique for dealing with sea lice using laser technology.

He visited many of the exhibitors, seeing the innovations that are taking place within the aquaculture industry from copper netting to mini subs.

The exhibition was staged over a large area comprising of five large halls on two levels, and an outdoor area. He would like to thank all the exhibitors he met with over the four-day period with special thanks to Fiskeriportalen, Damen Shipyards, Aquastructures AS and Gazelle Technology AS.

We look forward to returning to Aqua Nor in 2015, so until then we wish all the companies we met with and those we did not all the success for the future.

Tilapia is a cheap source of protein and popular food fish that has been pond farmed for thousands of years. For

instance the Ancient Egyptians farmed tilapias along the Nile. Today, tilapia farming is becoming popular around the world.

Cage farming of tilapia makes it possible in bodies of water where draining and seining or harvesting would be difficult or impossible. Cages are for instance utilized in lakes, large reservoirs and rivers. They are also a good alternative for estuaries and coastal embayments, and have been successfully used for farming tilapia in cooling water discharge canals. The cages consist of mesh in order to let the water circulate freely. Tilapia are among the most suitable fishes for fish Cage farming.

Savanna Streams, (an Aquacultural Business Endeavour; from production of quality seeds, pond and cage culture, feed manufacturing, EM (effective microorganism) production and extending technical support) are promoting Low Volume High Density (LVHD) Cage farming of Tilapia to benefit the small scale farmers, and village people to raise their own fish in Zambia. To make low cost protein source available/accessible for the villagers.

Low Volume High Density fish cages are compact cage with a volume ranges from one cubic meter to 30 cubic meters, and can yield up to 100 kilograms of fish per cubic meter. LVHD fish cage farming was introduced in China in 1991, with

remarkable success. The frame can either be made of HDPE pipe (in our case), bamboo, wood or steel bars, or which is cheaper in the Locality as long as it must be build strong and durable. The netting materials should be made of nylon net provided with predator net at the outside. Advantages of LVHD fish cages:

1. Lower investment cost-‐ideal for small scale farmers.

2. Easier to transport, set-‐up, maintenance and harvesting.

3. Close observation and monitoring of fish growth, health and feeding response.

4. Economical, and easy to manage for fish treatment of parasites and diseases.

5. Due to its compact volume, the water quality is always good, which promote a higher yield.

Disadvantages of LVHD cages:

1. Depend totally to artificial feed. 2. Risk of loss from poaching, or damage by

predators and of bad weather. 3. Greater risk of disease outbreaks if not manage

properly. Placement and proper installation; The LVHD cages should be ideally be placed when the water current is strong, to maintain good water quality all the time. Avoid stagnant water, it promotes bad water quality. Do not place the cages where there is always flood.

3. Greater risk of disease outbreaks if not manage properly. Placement and proper installation; The LVHD cages should be ideally be placed when the water current is strong, to maintain good water quality all the time. Avoid stagnant water, it promotes bad water quality. Do not place the cages where there is always flood.

Maintain a proper spacing between cages. To promote good water circulation provides at least five meters space between cages. The cages must be installed at least 1 meter above the bottom, to discharge easily the waste of the fish. Installed them in a straight line configuration perpendicular to the direction water current to enable the frequent and unrestricted water exchange and maintain the good water quality.


Photo Caption: Proper spacing of LVHD cages Important reminder: Avoid low temperature. The ideal temperature to achieve good growth is 28-‐30°C. The growth will dramatically decline when the temperature goes down to 20°C. Tilapia will start to die at 10°C Please also note that a temperature below the optimum range will have a negative effect on the immune system of the fish. They might survive at first, but eventually will be susceptible to diseases.

Higher Waves, Stronger Currents No Upset for Faroe Fish Farmers

Battered by extreme weather and sea conditions in a natural environment far more hostile than most other places—Faroese fish farms are built to last, using the most robust equipment in the world, according to Vónin Aquaculture. For most fish farmers, a wave height of 8m is rather unthinkable, not to mention a current strength of 0.8m per second. Now go to the Faroe Islands and you will soon see that such conditions are considered nothing out of the ordinary—that is, they are quite common during winter in certain locations, as measured in 100-‐hour blocks. Extreme conditions by Faroese standards, is quite a different thing. Back in November 2011, Landsverk, the Faroese Public Works Agency, recorded wave heights of up to 19.7m, in fact the highest ever since records began in the late 1960s—possibly the highest on record anywhere, according to the agency. Even on that occasion, Faroese fish farms largely suffered no significant damages, however one installation had its anchorage compromised and started drifting.

“I remember this person was nervous about his fish farm which had shifted position by some 70m in a very short time,” said Signar Poulsen, manager at Vónin Aquaculture. “One of his larger floating frames had snapped and was only being held together by the net cage itself, which fortunately was made of very strong Dyneema netting. So this was an emergency situation and we had three service teams mobilised to make sure the fish farm remained safe. It turned out to be intact except for the anchors used for keeping it in place and the one floating frame which had been broken in two but was held together by the net cage itself. We had it all repaired and back in place in a matter of hours. “The anchors were of the most robust kind but they had been dragged across the seabed by the force of the sea with the upper parts completely deformed. So the person was very happy to see everything resolved and the installation back in place with no damage to the fish farm.” Mr Poulsen added: “But such incidents are extremely rare in the Faroe Islands; I cannot recall any other time that something like this happened.”

‘Three times stronger’

Out of a total of 36, two fish farming locations in the Faroe Islands regularly have currents of up to 0.8m per second while two other have wave heights of up to 8m. As far as concerns equipment, the ability to withstand the elements is a standard requirement.

Today every aquaculture installation in the Faros uses equipment from Vónin Aquaculture, Mr Poulsen said.

“Our offerings range from complete solutions to component parts, from net cages to mooring systems and accessories.”

“Everybody is talking about taking fish farms further out to sea and in the Faroes, I’m afraid we don’t have much choice as the available space in sheltered sea areas is very limited. Fiskaaling, the Aquaculture Research Station of the Faroes is currently conducting a trial at an exposed site with plastic cages with net cages made of dyneema and nylon. So there is much focus on whether our standard equipment will be robust enough for use offshore. This particular trial site is directly exposed to the North Atlantic Ocean. Waves are expected to be up to 14 m.”

Vónin Net Cages are usually made from: • Nylon • Polyester • Polyethylene • Dyneema

Vónin also offers Net Cages made from other fibres such as Star Net.

What separates a Vónin Net Cages from others is the design of the net cage. A Vónin Net Cage is designed in particular way which enables it to be used at more exposed and shallow sites.

The net cage used at the trial site where waves are expected to be up to 14 m. is a standard Vónin Net Cage design.

“For us to be in a market where there is high competition among the producers of net cages and mooring systems, we have to be innovative and be price competitive. All the producers use to some extent the same raw materials. This is why we produce our net cages mainly outside the European Union and develop our own designs with the fish farmers for example in Faroe Islands, Norway and Scotland. This enables us to have low cost Net Cages with proven quality and proven high performance” – Signar Poulsen.

Fish farms are essentially underwater installations and according to Vónin, their Mooring System outperforms other systems on the market, much thanks to a unique design that includes a shock absorbing function that enables the installations to remain firmly moored to the seabed while seamlessly withstanding the forces of the sea.

Key components in a Vónin Mooring System: the Vónin Plates, of high grade, acid resistant stainless steel are virtually maintenance free and of galvanised steel where we stock plates up to 150 tonnages breaking strength.

“There is no need for using zinc blocks for protecting stainless steel,” Mr Poulsen said. “That on its own is a big money saver because it takes away the need to make frequent underwater inspections.”

We have 16 servicing departments spread over the whole North Atlantic Ocean, spanning five countries. Canada, Greenland, Norway, Faroe Islands and Denmark, where we stock our Vónin Net Cages and Vónin Mooring Systems.

Vónin Net Cages and Mooring Systems undergo rigorous quality tests in order to ensure strength and quality is never compromised. All Vónin products come with certifications.

Building on the strength of our fishing gear business since 1969, Vónin has become the preferred supplier for a growing number of fish farmers across the globe.

The focus of ProFlex is the complete net treatment solution- cleaning, drying, impregnating and protecting nets for the customer´s specific

demands.

The research and development has resulted in a water- based antifouling substituting the oil based antifouling for more environmental friendly protection. The existing antifoulants are formulated to extend the working time for net in the sea as well as high efficiency against most types of marine growth.

As our customers are facing different challenges around the world due to different environmental conditions, the demand for antifouling for specific needs has increased, and we have recently presented FLEXGARD VII- HD - an antifouling highly efficient against hydroids.

The intensive R&D work has also resulted in a net impregnation - FLEXDIP accepted for ORGANIC fish farming of all species.

And finally, we have seen very good results for our FLEXGARD XI- C on PE- nets. The challenge in the business has been the adhesion to the PE- nets- but now we have solved this- and recommend our FLEXGARD XI- C to PE nets as well as other net types- nylon, Dyneema etc.

Latest development in the ProFlex company- is a complete range of machinery for net service- from cleaning to antifouling. We evaluate and analyze the customer´s situation, advice on how to eliminate the bottlenecks and solve the specific challenges for our customers.

We offer the net washers suitable for all net sizes and an additionally separator enabling a separation between the water and the solids- and the water is ready for re- use. We also offer the net washer in different sizes for the farmer doing his own nets but also in larger scale for the net service companies.

A drying system ensures that the net is completely dried before impregnation or transport and make you independent of the weather situation and the drying system is also offered in different sizes customized to the specific needs.

Finally we have agreed with the Norwegian company Stette that ProFlex is their agent outside Norway and the Benelux. The impregnator produced by Stette operates via vacuum and offers a range of benefits for the customer- less antifouling consumption- ‐ flexibility to change between the products – time saving and finally very environmental friendly compared to traditional way due to a closed system avoiding leaks to environment. So now ProFlex is well prepared to work with the fish farmers and the net service companies on their specific challenges and demands around the world.

Last year AquaTech received an order to supply of two complete net cage systems, for the (approx. 30 ha large)

mining/dredge lake “Tröbitz” in Brandenburg/Germany, with a total of 12 cages (each 4,0x4, 0x3,5 m), consisting of 200 m2 “Maritime Technic” pontoons in gras- green (RAL 6010).

The cage nets consist of black polymere covered polyester net material (MS 20 mm), and are very robust and long lasting. The cover nets, consist of green, rasheled polyethylene net material (MS 20 mm), and act as protection against birds. Beside the nets, solar powered fish feeders (45 l volume) with double gallow- frames were also delivered. In the cages, mainly common carps (Cyprinus carpio) are raised and also overwintered there with very low mortality.

The results from the first year are promising - one summer old carps with approx. 69 g each where overwintered in the cages under ice. They where feed from April to October with dryfood (40 %RP/24 % RF) and grown in 195 days, with a food conversion rate of just 1,17 to a final weight of 558 g each (daily growth rate 1,08 %). The final stocking density was about 21 kg/m3 and the total mortality below 0,7 %. The “Institute of Inland Fisheries, Potsdam- Sacrow”, will guide the system scientifically.

Also this year AquaTech received an order to supply a net cage system, for a traditional pond farm in Hungary, with four cages (each 4,0x4, 0x2,0 m), consisting of 57 m2 “Maritime Technic” pontoons in gras- green (RAL 6010). The cage nets itself, consist of black, polymere covered polyester net material (MS 20 mm), and are very robust and long lasting. Beside the nets, solar powered fish feeders (45 l volume) were also delivered. In the cages, mainly common carps (Cyprinus carpio) are raised and overwintered. In this way, the heavy fish losses due to predation of cormorants (Phalacrocorax carbo) in the natural ponds can be reduced or avoided. Additional net cage systems with 10 cages (each 5,0x5, 0x2,0 m), consisting of 160 m2 “Maritime Technic” pontoons in gras- ‐ green (RAL 6010), have been installed this year.

Last year AquaTech received an order to supply of two complete net cage systems, for the (approx. 30 ha large) mining/dredge lake "Tröbitz" in Brandenburg/Germany, with a total of 12 cages (each 4,0x4, 0x3,5 m), consisting of 200 m2 "Maritime Technic" pontoons in gras-‐green (RAL 6010). The cage nets consist of black polymere covered polyester net material (MS 20 mm), and are very robust and long lasting. The cover nets, consist of green, rasheled polyethylene net material (MS 20 mm), and act as protection against birds. Beside the nets, solar powered fish feeders (45 l volume) with double gallow-‐frames were also delivered. In the cages, mainly common carps (Cyprinus carpio) are raised and also overwintered there with very low mortality.
