In the terrestrial animal feed industry the use of exogenous enzymes is a relatively common practice and today the global feed enzyme market is worth more than US$550 million. This saves the global feed market an estimated US$3-5 billion per year. To date the use of enzymes in aquaculture feeds has been limited, but interest is growing due to the increasing use of plant based protein ingredients and their by-products.
In recent years, aquaculture has gained in importance as a renewable source of dietary protein and as a viable commercial activity. To maintain this position in the future and to continue to provide a good investment opportunity, the problems the sector currently faces must be addressed. One of the more important of these concerns is the cost of feed, which is estimated to be 50-60 percent of the total cost of production. Numerous studies on the use of different feed formulations, feed ingredients and feeding techniques have been conducted (Kaushik et al., 2004; Thiessen et al., 2003; Martinez et al., 2004; Enes et al.,2006; Izquierdo et al., 2003). These studies have included assessments of various alternative raw materials, vitamins and minerals, monitoring the amount of feed provided to the fish, and the addition of pigments and other feed additives to the diet. In particular, various feed additives with growth promoting properties came into prominence in these studies (Francis et al., 2005; Haroun et al., 2006; Abdel-Tawwab et al., 2008; Lara-Flores et al., 2003; Li and Gatlin, 2004;). Growth promoting feed additives may contain different ingredients as plant extracts, organic acids, probiotics, hormones etc.
The world demand for seafood is increasing dramatically year by year, although an annual upper limit of 100 million tons is set so as not to exhaust reserves. It is for this reason that there is a considerable move towards modernising and intensifying fish farming. To be economically viable, fish farming must be competitive, which means that feed costs amongst others must be carefully monitored as the operational cost goes 60 percent for feed alone. Therefore selection of cheaper and quality ingredients is of paramount importance for sustainable and economical aquaculture. Identification of suitable alternate protein sources for inclusion in fish feeds becomes imperative to counter the scarcity of fishmeal.

After the BSE crisis in the EU in late 2001, processed animal proteins (PAPs) were banned from utilisation in feeds for aquaculture and livestock. Some products were re-introduced in 2005 (blood products, milk products, hydrolyzed proteins, gelatin) as they did not pose any risk of transferring BSE to consumption animals. Meanwhile the bulk of processed animal proteins was used for other applications and exported to markets outside Europe.

With aquaculture becoming increasingly important for the production of animal proteins on a global scale, it is no wonder that interest has also grown in the optimisation of the nutritional and technological quality of aquafeeds.
Spray-dried plasma from porcine blood in diets for Atlantic salmon parrsInternational Aquafeed
Â
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.
Effect of dietary inclusion of seaweeds on intestinal proteolytic activity of...International Aquafeed
Â
In the last years considerable attention has been paid on the use of seaweeds (SW) as a possible ingredient for aquafeeds. Red, green and brown SW can be taken from their natural habitat and brought to the shore by the action of winds and tides. Otherwise, biomass can be obtained from secondary and tertiary treatment of effluents. Wastewater treatment utilising photosynthetic organisms is an interesting alternative to reduce the ecological impact of domestic, industrial or aquaculture effluents. Generally, high-quality algal biomass is yielded from algal cultivation, representing an excellent source of hydrocolloids, carotenoids, and bioactive substances, which allows different industrial applications. In addition, there is currently an increasing interest for the potential of SW in human and animal nutrition.
The multifunctional dietary properties of spirulina and its use in aquacultureInternational Aquafeed
Â
In commercial and high stocking density culture practices, feeding plays a significant role in fast growth and high yields. Aqua feed contains many ingredients in highly balanced nutritious components for enhancing the digestive mechanisms in fish and shrimp bodies. It leads to better body weights and health, optimum immunity and greater survival rates. Spirulina is a unique high quality natural diet with enriched optimum protein for fish and shrimp which is proven to be a suitable supplementary feed in aquaculture.
Duckweed is the smallest flowering plant in the world, an aquatic plant which can be found in fresh water or wetlands in most corners of the world that do not freeze too frequently. Floating on or just below the surface of still or slow-moving bodies of water, many around the world perceive it as a pest, claiming it âclogs up lakes or pondsâ.

Aquaculture reached a landmark in 2009, supplying greater than half of the total fish and shellfish for human consumption (Naylor et al. 2009). With global fisheries in decline and human population increasing, the gap between protein supply and protein demand is widening. Aquaculture must continue to expand to meet these growing needs, and it must do so in a safe, sustainable manner that decreases the worldâs reliance on harvesting fish for fishmeal while still producing a high quality product. There are several difficult hurdles the aquaculture industry now faces if this needed growth is to occur.

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
Â
With an estimated market value of over ÂŁ1.8 billion and Scottish salmon exports alone reaching over ÂŁ500 million, Scotlandâs 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 organisationâs 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 1990âs 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 ÂŁ30 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.
In the past 50 years, the global demand for fish products has doubled, and more than 45 percent of the worldâs 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.
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
Â
The nutritional quality of larvae diets affects fishesâ 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.

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 PegasusÂź 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 PegasusŸ 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; thatâs why most aquafeed producers diligently track the cost of fuel used in their drying operation.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
Â
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more âmechanicalâ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!
