Professor Krishen Rana Professor Krishen Rana is a lecturer in Sustainable Aquaculture Development at the University of Stirling, Scotland. Professor Rana joins International Aquafeed magazine as Associate Editor - Feed Management and Sustainability from this month. Professor Rana has a BSc in Environmental Biology from the University of London and a PhD from the University of Stirling in aquaculture. He has worked in the field of aquaculture in reproduction and genetics and in aquaculture systems development for 30 years, 26 of these at the Institute of Aquaculture where he has held posts ranging from post-doctoral research fellow through research lecturer and currently lecturer. He was seconded to FAO Fisheries Department for nearly five years addressing global issues on aquaculture development including the FAO ‘Code of Conduct on Aquaculture’ and is currently a visiting Professor on Sustainable Aquaculture at the Division of Genetics, Stellenbosch University in South Africa. His research interests and activities encompass aspects on genetics, especially management of hatchery stocks and seed production, reproduction of warm water species, feed management and onfarm aquafeeds and farming systems development and management of fish for food and ornamental purposes. Current interests include development of appropriate intensification systems recirculation systems, water management, including aquaponics and entrepreneurship development in aquaculture in African countries. Professor Rana has over 25 years overseas project experience and has authored/co-authored more than 100 publications linked to sustainable aquaculture.

In recent years, significant progress has been made in improving feed quality and performance and in securing a diverse basket of evaluated raw ingredients for aquafeed manufacture. The biological and economic performance of these aquafeeds in context farming systems however, will determine the overall acceptability and affordability of aqua feeds. International Aquafeed will develop these themes through sharing experiences on how various types of aquafeeds, ranging from farm-made feeds to industrially manufactured feeds perform at farm level and how feed management

practices, including the use of feeds as delivery systems for enhancing survival and growth, and how management of the culture environment across the continents are used to optimise or improve the value and costs of feeds. This is a new section in IAF that looks specifically at feed management on farm. The first feature is an introductory article that presents an overall view of aquaculture and identifies some major challenges facing the sector.

Global challenges facing the industry and primary issues and challenges in aquafeeds It is now widely recognised that to meet rising demand for aquatic products, aquaculture will have to meet shortfalls in predicted supply, but is aquaculture growth adequate to meet this challenge? Data from FAO confirm that the contribution of aquaculture to total fishery products - excluding plants - has steady increased form four percent in 1970 to account for 36 percent in 2006. According to FAO, the global production from aquaculture reached 66.7 million tonnes in 2006. This global output, however, is signifi-

Figure 2: A breakdown of production costs of industrial feed in Europe. Raw materials account for approximately 75 percent of the overall production cost. In 2007, approximately 62 percent of raw material costs were for proteins and 25 percent for oils. Even although premixes are around one percent by volume they account for 13 percent of costs cantly influenced by China, which accounted for 45 million - or 70 percent - of global production in 2006 and this masks the heterogeneity of development, and opportunities and challenges especially for the aquafeed industry that will have to play a

key and increasing role in securing expected production targets. In the recent past (1986-2000) the average annual global aquaculture growth rate was an impressive 19 percent - but without China, the annual growth achieved was only 5.5 percent. 42 | InternatIonal AquAFeed | July-august 09

The rate of growth of the sector has shown signs of slowing down indicating that we may be approaching the production capacity (Table 1) under current conditions. In the last five reporting years (2001-2006), increased production from Thailand, Indonesia,Vietnam and Philippines has boosted growth in Asia, but overall growth rates are still slowing down whilst aquaculture expansion has stagnated in Europe.

What options do we have to increase production from aquaculture and their implications for feeds? Countries have two principle options: 1) increase land and water area under culture and avail access to these resources and, in tandem 2) intensify production and improve productivity. Both these approaches pose significant challenges for the sector. Aquaculture, which is dependent on water either seawater or inland fresh water and on land resources, competes with other users for other economic purposes such as recreation, urbanisation, industry traditional agriculture and livestock, domestic and direct consumption, and infrastructure development. For fresh water aquaculture, access will also be governed and limited by the scarcity of water resource especially if national withdrawal exceeds a quarter of actual renewable water resources (that is critical ratio is equal to 25 percent). This is further complicated by the degree of dependency of a country on waters originating form outside their national boundaries (dependency ratio). The high percentage water withdrawal indicator (critical ratio) among the leading aquaculture countries in Asia points to a possible water limiting factor for aquaculture development in China, India, Thailand and Japan. The high dependency ratio indicator, for Bangladesh (91 percent) and Vietnam (60 percent) may suggest increased competition from other sectors and countries with which they shares this resource. In the light of probable increased competition for land and water throughout many major aquaculture producing countries, especially in Asia, there will inevitably be increasing pressure to increase production through intensification.

This trend is already evident. Regards low value herbivores and omnivores species, production is migrating rapidly from extensive to semi-intensive methods using low-cost farm-made aquafeeds. Recent global aquafeed production and number of farms dependent on aquafeeds illustrate this. In 2003, global aquafeed production was estimated at approximately 19.5 million tonnes, but expected to increase to over 37.0 million tonnes by the end of this decade.

Feed ingredients to service intensification The assured supply of raw ingredients, at an acceptable price, quality and performance, is critical for global aquaculture expansion and therefore the issues and challenges that influence sustainability, availability, quality, price of these ingredients and the performance of diets using these ingredients at the ‘coal front’ will be explored in future issues. Aquaculture is reliant on a basket of common input ingredients, such as soy, corn, fishmeal, fish oil, rice and wheat, for which it competes in the market place with other animal protein production sectors such as beef, poultry and pork as well with direct human consumption. Many of these key ingredients are traditionally used in recipes for commercial or on-farm aquaculture feeds are internationally traded commodities and therefore aquafeed production is also subjected to any global market shocks and volatility.
