The document summarizes some of the products and developments that were showcased by exhibitors at the Aqua 2012 conference and trade show in Prague, Czech Republic from September 1-5, 2012. It highlights products from several companies, including Aliphos Blue Line aquaculture feed ingredients, Sonac announcing that some animal proteins will be cleared for use in aqua feeds from June 2013, LGem's GemTube photo-bioreactor for algae production, Shellfish Diet 1800 mixed microalgae diet for bivalve shellfish, Nutriad's AquaGest line of feed additives, and LARVIVA ProStart early weaning diet with probiotics to reduce deformities in fish larvae.
In the past 50 years, the global demand for fish products has doubled, and more than 45 percent of the world’s seafood today now comes not from wild catches, but from either land-based or offshore fish farms. To meet this rising demand for seafood worldwide, more fish have to be raised in fish farms, and aquaculture is an essential link in the agricultural chain.
The venue for this special event was Fishmongers Hall, London Bridge, London – a historical site in terms of what was to be discussed and highlighted, where the industries involved had come from to where they were headed to, all connected through BioMarine. The Hall, sitting alongside the River Thames, dates back to Neolithic times with the British Museum having a decorated bowl (3300–2700 BC), found in the river.
Feed formulation is the major part of aquaculture.The main objective of feed formulation is to utilize the knowledge of nutrient requirements, locally available feed ingredients and digestive capacity of fish for the development of a nutritionally balanced mixture of feed stuff…
The global fish consumption for human nutrition increases. The supply of enough aquatic products is still possible, because the experienced fish capture peak in the 1990s is buffered by the increasing amount of fish from hatcheries, both onshore and offshore.

The potential of microalgae meals in compound feeds for aquacultureInternational Aquafeed
Intensive production of mainly carnivorous fish has resulted in fish feeds containing high levels of fishmeal and fish oil, with Europe requiring around 1.9 million tonnes a year. Although this use of fishmeal was initially the recycling of waste from fishing through the use of bycatch and trimmings, due to the rapid development of aquaculture this reliance on fishmeal and fish oil is environmentally unsustainable. This has resulted in other sources of fish feed being investigated. This literature review will focus on microalgae; the composition in terms of nutritional quality, the current methods of production and associated costs along with potential future uses such as feed in aquaculture.
Interest is burgeoning in a unique new low-pressure oxygenation system that is poised to transform the world of aquaculture. The uniqueness of the technology is based on its ability to perform three critical functions in one system— dissolving oxygen in the water, producing the correct hydrodynamics and stripping out potentially harmful inert gases like nitrogen — via a very low energy requirement. Moreover, the system is easily installed, including as a retrofit to existing fish tanks, and is virtually maintenance-free.
Utlisation of Roasted Guar Korma as alternative for fishmeal and soybean meal...International Aquafeed
Roasted Guar Korma is a high protein raw material, obtained after extraction of Guar gum from the seeds of the leguminous plant Cyamopsis tetragonoloba. It is cleaned and roasted after the gum extraction to remove anti-nutritional factors present in korma, such as trypsin inhibitor, improving its nutritional values and total digestibility.
Equipment failure or operational errors are behind three out of four farmed salmon escapes. Two out of three escapes are due to holes in sea cage nets according to a new study.
Spray-dried plasma from porcine blood in diets for Atlantic salmon parrsInternational Aquafeed
Since the late 1970s, Atlantic salmon aquaculture has grown into a global industry that annually produces over 1.4 million tonnes of salmon with an estimated value of US$7,812 million according to 2012 FAO statistics. The growth of salmon aquaculture has been accompanied by a continuous improvement in feed formulation and technology to maximize growth and survival of salmon at different stages of development. The search for new and alternative feed ingredients and formulations continues in order to ensure sustainability of this industry.

The green water encouraged by the traditional carp farmers in the Far East and then Europe would be rich with live infusoria including cilates and freshwater rotifers for first feeding. The marine fish industry has had to look at marine rotifers and recreating the plankton soup as many larval species are too small to take newly hatched Artemia. The leading research labs using fish in medical and ecotoxicology projects that have relied upon lab-grown Paramecia cultures are revisiting rotifer culture to maximise fry survival rates.

About 50 percent of the costs related to farming of salmon and rainbow trout are spent on feed (Fiskeridirektoratet, 2012), and the estimated feed loss from commercial sites is 5-7 percent (Cromey et al., 2002; Gjøsæter et al., 2008). This amounts to a considerable annual economic loss for the farmer.

The annual global production of fishmeal and fish oil is currently around five million tonnes of meal and one million tonnes of oil (Figure 1), except in years when the fishing in the South Pacific is disrupted by the warm waters of an El Niňo, most recently in 2010. Around 22 million tonnes of raw material is used, of which approximately 75 percent comes from whole fish and 25 percent from by-products of processing fish for human consumption (IFFO estimates).

The Salmonidae family, collectively known as Salmonids, comprises of salmon, trout, chars, freshwater whitefishes, and graylings, but it is the trout and Atlantic salmon, of the genus Salmo, which gives the family their name. A slender teleost fish, they can range in size between just 13 cm to a whopping 2 m in length. With a single row of sharp teeth, Salmonids are predators, choosing to feed on smaller fish, aquatic insects and small crustaceans. Despite spawning in fresh water Salmonids are mostly anadromous, spending their lives at sea, choosing only to return to rivers to reproduce.
Innovation nation - How new developments in aquaculture are boosting the Scot...International Aquafeed
With an estimated market value of over £1.8 billion and Scottish salmon exports alone reaching over £500 million, Scotland’s aquaculture sector is fast becoming a core pillar for the future growth of the Scottish economy. However, with such a steep increase in the demand for fish products, there is a real need for innovation within the sector to stay ahead of the curve and provide a sustainable supply of healthy protein; not only for the present but for the future of a market that appears set to keep growing. Ahead of Aquaculture UK, CEO of the Scottish Aquaculture Innovation Centre (SAIC), Heather Jones, shares some of the organisation’s forays into finfish research projects and the ways in which is working with both industry and academia to enhance the whole of the Scottish aquaculture sector.
The Asian catfish Pangasius, Pangasianodon hypophthalmus is recognised as a leading aquaculture food fish on world markets. The commercial culture of Pangasius was developed in the mid 1990’s in Vietnam and quickly expanded to production levels of nearly one million tons per year. Other countries including Thailand, Cambodia, Myanmar, Indonesia, Philippines, Bangladesh and India have adapted Pangasius as part of their aquaculture production. Pangasius can be successfully cultured in most tropical regions of the world however countries in the Western Hemisphere have been slow to embrace Pangasius aquaculture, in part, due to the lack of practical knowledge of the species food requirements during the larval and fry stages.
Mud crabs, also known as mangrove crabs, occur widely in estuaries and along tropical, subtropical and warm temperate coasts in the world. There are four species of mud crab (Family: Portunidae), Scylla serrata, S. tranquebarica, S. paramamosain and S. olivacea that are the focus of both commercial fisheries and aquaculture production throughout their distribution. They are among the most valuable crab species in the world, with the bulk of their commercial production sent live to market.
The European lobster (Homarus gammarus) is an ecologically important species of the North-eastern Atlantic which supports wild trap fisheries that are worth around £30 million each year to the UK alone. By weight the species is the highest-value seafood among those landed regularly in the UK and Ireland, where 75 percent of the ~5,000t annual landings for the species are made. As such, lobsters provide essential diversity to fragile inshore fisheries and vital income for rural coastal economies. However, populations across its range are pressured by rising exploitation, from which traditional fisheries management has failed to prevent extensive regional stock collapses in the recent past, and now struggles to stimulate recovery. While lobsters have long been transported as a live export commodity, chiefly to France and the Iberian peninsula, emerging markets, particularly those in East Asia, threaten to create additional demand for the species which far exceeds current capture yields. Improvements in hatchery rearing success have seen a number of recent aquaculture initiatives employed, in the hope of both generating restoration and improved sustainability of wild harvests, and instigating commercial aquaculture possibilities.
When farming animals and fish, there is often a danger that we may assume that their dietary requirements match our own. However, those of the common carp, Cyprinus carpio, certainly do not.
Mexico, with a population of 122 million is the most populous Spanish-speaking country in the world. The country is known for its Pacific and Gulf of Mexico beaches and its diverse landscape of mountains, deserts and jungles. Ancient ruins such as Teotihuacan (Aztec), Chichen Itza (Mayan) and Spanish colonial-era towns are scattered throughout the country.
The quality and digestibility of proteins is one of the most important issues in shrimp nutrition. Marine proteins (mainly fish meal) can only be partially replaced by standard vegetable proteins like soybean meal.
KRILL OIL: Phospholipids that make a difference to filet quality and quantityInternational Aquafeed
The nutritional quality of larvae diets affects fishes’ fillet quality and quantity. Studies show that phospholipids increase fish larvae growth and development; so phospholipids are an essential component of the early weaning diet.
Carbohydrates are an excellent source of energy and carbon in feed formulations. They can be easily distinguished from the other energy yielding nutrients in terms of their abundance and low price. To illustrate, the collective global production of the major cereal grains i.e., maize, wheat and rice amounted to a colossal 2.5 billion tonnes in the year 2013 (FAO). The total carbohydrate content and the digestible fraction of starch and sugars in these grains can be roughly estimated to be about 2.1 and 1.75 billion tonnes, respectively (www.feedipedia.org). Besides, the unit cost of carbohydrate sources is almost three to five fold less than that of the protein and lipid sources of interest. Therefore, the inclusion level of carbohydrates in commercial fish feed assumes direct economic significance i.e., in terms of lower feed cost per unit weight gain.
Brewers’ yeast and derived products have been successfully used in animal nutrition, including aquafeeds, for several decades now. Leiber GmbH, with two production sites in Germany and further facilities in Poland and Russia, have manufactured brewers’ yeast products for more than 60 years.

The Latin names of some aquatic species can have fascinatingly obscure meanings that provide anyone in need of a hobby with hours of joyful investigation and speculation. The channel catfish is, alas, not one of them: Ictalurus punctatus simply means ‘spotty catfish’, and the briefest glance at one will tell you why.
It is often thought that vacuum coating was firs t invented in Norway. The idea might have been Norwegian, but the technology was developed in the Netherlands. It has been 25 years now since Dinnissen, together with aquafeed producer Skretting, invented the firs t vacuum coater.
The Pegasus® Vacuum Coater is intended for everyone who wishes to manufacture pelleted and extruded products in accordance with mos t modern production specifications.
It allows you to create a vacuum environment for your production process and to deal effectively with a very wide range of future challenges.
International Aquafeed spoke to Peter Raeven, Account Manager for Dinnissen, about the previous 25 years of the Pegasus® Vacuum Coater as well as any future plans that Dinnissen might have for their now well es tablished brand.
As an aquafeed processor, you are always aware that your drying operation has a significant impact on your bottom line. Drying is a very energy-intensive operation; that’s why most aquafeed producers diligently track the cost of fuel used in their drying operation.
