25/04/2017: Wholehearted focus on salmon fed with microalgae

by Lerøy

Lerøy will from next month produce salmon products rich in healthy fatty acids – with a reduced usage of scarce marine raw materials

A close cooperation between Lerøy and BioMar is going to ensure that salmon farmed by Lerøy will benefit from a sustainable high level of Omega 3-DHA in the feed partly deriving from the microalgae ingredient, AlgaPrime DHA.

Lerøy states that this cooperation is an important step taking responsibility for building an even more sustainable aquaculture. Lerøy is now entering a new area of sustainability.

Salmon, above 1 kg, will from next month be farmed by the use of feed formulated with microalgae, a sustainable, Omega-3-rich whole algae ingredient developed by TerraVia in partnership with Bunge. Using the new ingredient Lerøy unreserved embarks a journey of reducing dependency of marine ingredients.

“For the end-consumer this change means that we will be able to keep the high level of healthy Omega 3 in the ‘Lerøy Salmon’. We know there will be a lack of fish oil in the future and that we have to find alternatives to fish oil, as a feed ingredient, if we want to keep the high level of healthy Omega 3 that we have in the salmon today. With the use of feed formulated with microalgae we are certain to maintain the high level for many years to come”, states Henning Beltestad, CEO in Lerøy Seafood Group.

The feed supplier BioMar has developed a range of feed solutions for Lerøy, where a part of the high level of healthy Omega 3 is obtained through use of microalgae. “We farm salmon for the end-consumer.

We know that the consumers all over the world care about the sustainability of our activities and the nutritional quality of our salmon. Through this efficient cooperation we have been able to take the volume of salmon being fed in a more sustainable way to a significant level within a short time frame.

BioMar has been at the forefront looking out for new opportunities within sustainable ingredients, and we need new raw materials to be able to follow the demand for healthy seafood. To us it is extremely important that the entire value chain takes responsibility in developing an even more sustainable aquaculture”, explains Henning Beltestad, CEO in Lerøy Seafood Group and continues,

“The consumers must be able to choose from a healthy salmon product range with a solid sustainable profile every time they select the ‘Lerøy Salmon’. We would like to take this step wholehearted as we believe that it is important for the industry to engage in implementing new feed solutions that balances high health value and sustainability”.

BioMar has been taking lead in developing and testing feed with microalgae, bringing new feeds incorporating the ingredient to the market at a commercial scale in 2016. Since September 2016 more than 40.000 tonnes of feed has been brought to market – mainly consumed by Lerøy.

“We are very pleased that we have been able to contribute to developing healthy and sustainable salmon products together with Lerøy. It is vital to BioMar working in a close partnership with our customers and suppliers. To us it is evident that we need cooperation to develop the industry”, states Jan Sverre Røsstad, Vice President for the Salmon Division in BioMar Group.

As a supplier of microalgae Omega-3s to the aquaculture industry, TerraVia’s joint venture with Bunge has experienced the close cooperation with BioMar and Lerøy as a very valuable way to innovate aquaculture, “Lerøy and BioMar have collaborated closely with us throughout the commercialisation of AlgaPrime DHA to ensure that we are delivering sustainable, cost effective, and relevant products at the right scale to meet the challenges of the salmon industry. By leveraging our respective core competencies, we’re now able to create meaningful results for consumer health, and to broaden the available pool of Omega-3 oils for aquaculture, enhancing the sustainability of the industry. TerraVia’s joint venture with Bunge in Brazil has successfully scaled its AlgaPrime DHA Omega-3 manufacturing capability, and is now delivering consistently as a critical ingredient of BioMar’s feed formulation for Lerøy” explained Graham Ellis, Senior Vice President of Business Development at TerraVia.

25/04/2017: The influence of an automatic feeding device for frozen zooplankton

by Martin Hochleithner, AquaTech, Austria

AquaTech (Aquaculture Technology) is the name of an Austrian company that produces and supplies innovative and efficient technology for use in aquaculture


 Products developed initially in Austria are well known and used worldwide, like the older clockwork-belt feeder or the newer solar-feeders. 


 
www.aquaculture-com.net
At the vanguard of aquaculture development, Austria has a long tradition in the successful use of live zooplankton caught from natural waters as starter feed for various fish larvae raised in tanks (Einsele, 1949).

Less known are the recent Austrian developments for harvesting and grading of zooplankton, for example a multi-sieve plankton-net (Steiner & Hochleithner, 2016).

Another such innovative and unique product is an automatic feeder for the professional controlled administration of frozen zooplankton in hatcheries or nurseries. This patented “Planktonfeeder”, developed at the “Institute for Fish Research” in Austria, is available in its third generation.

It has dimensions (L x W x H) of about 79 x 49 x 73 cm and can accommodate in two compartments up to 20kg of frozen zooplankton. The feeding technique is based on an electronic controlled process, which "washes" the plankton layers off larger-sized frozen pieces and distributes the rations evenly via two specially designed, self-cleaning systems of up to 16 outlet valves.

If Y-shaped adapters are used, the unit can even supply up to 32 tanks with plankton. The "washing" and defrosting of the plankton layers achieved by spraying or flooding with water, and the remaining plankton is then re-frozen.

In order to avoid the crushing or damaging of the defrosted fragile plankton organisms, distribution to the nursery tanks is carried out along with water current in flexible tubes.

Wild-caught zooplankton, mainly copepods and phyllopods, which make up over 90 percent of total zooplankton biomass in lakes and seas, is the optimal food for fry and fingerlings up to a size of 3-5cm (Hochleithner, 2001).

It serves as initial feed for the production of sensitive and valuable fish stocks of species such as char, grayling, whitefish, eel, sturgeon, bass, bream, and numerous others (Steiner, 1989).

24/04/2017: Catfish feed for Africa

by Dr Hanno Slawski, R&D Manager, Aller Aqua, Denmark

The African catfish is of increasing popularity as fish for aquaculture production

The versatility and robustness of Africa catfish allow the species to thrive in challenging environments. 


 
www.aller-aqua.com
Especially in Africa, catfish farming has been increasing over the last few years and is about to increase further. Some constraints, however, limit the production increase. Among them are feed quality and availability.

Farming and marketing of catfish In Africa, Nigeria is the biggest producer of African catfish. In hatcheries, catfish hypophysation for induced spawning is a common practice. Catfish fry are obtained continuously, thus, stocking material is available all year.

In small on-land tanks, fish are grown to 2-5g, and are afterwards stocked into earthen ponds or tanks. Due to water shortage and energy cost, fresh pond water is a limitation. Most tanks are filled with a certain amount of fresh water in the morning, replacing used water.

That means rapid changes in water quality after the water exchange. Often, the water exchange is followed by the first daily feeding. Multiple feedings or demand feeders are seldom principles. Instead, a meal in the morning hours and one in the late afternoon are common practice.

The typical market size of African catfish in Nigeria is around 1kg. It is said, that the fish should reach this size in approximately four months after stocking fingerlings into ponds or tanks. The preferred fish in the market is relatively short and round.

Catfish farmers therefore aim to produce catfish with a relatively high condition factor, letting the fish grow fast. The last period before selling the fish is called “fattening period”. Fish are fed to obtain the shape desired by the market.

Fish are mostly sold from the farm to small retailers, especially market women. They visit the fish farms before going to the market.

Thus, fish are harvested daily, keeping the supply chain for fresh fish intact. On bigger farms, several size classes of fish are standing stock, so that continuous supply of fish to the market is possible.

Feed quality
Challenges with power supply and water quality can occur, setting high demands on farm management and fish care. If the fish do not grow as fast as expected, feed quality is quickly questioned, since water parameters are difficult to monitor and less seen as a potential variable determining fish growth.

Thus, stable feed quality becomes an important tool to steer farming success. When approaching the Nigerian catfish feed market, Aller Aqua aimed at delivering high performance feeds that were different to available products.

For this, feeds were collected from the market and tested in feeding trials with African catfish in Aller Aqua Research in Germany.

The trial results delivered important information about composition and quality of catfish feeds and potential for improvements included in the newly created catfish feed range.
