Why this Brief?


The world population growth - World Statistics, and increasing average standard of living, implies an increasing demand on feeds - total world feed output is approximately 614 million tonnes - IFIF Statistics. Animal feed consumption already exceeds direct human food consumption by almost four, and this ratio can only rise as the demand more animal protein increases. The ability to produce increasing amounts of feeds is one of the greatest challenges facing mankind, perhaps even greater than the environmental, energy, global warming and resource crisis. An increase in world population plays an important role on increasing feed demand. For instance, there are currently 6.5 billion people in the world. It is estimated that by 2030 there will be 2 billion more mouths to feed. This world population growth is driving meat consumption, and more meat means more grain … feed demand and animal feed supplements are rising!

Microalgae can play an important role in the future. They are one of the potential sources of foods and feeds provided by Nature with the potential to feed an ever growing and affluent population. Microalgae are the photosynthetic organisms in the first levels of the aquatic food-chains, on which an ever growing part of our food will have to come from. Our challenge is to domesticate these plants, as we have done with higher plants, to allow us to manage their large scale production for a wide range of applications, including feeds.


This Brief aims to (1) bring together the most relevant information available on microalgae feed production – and (2) promote the knowledge management to help accelerate the development of algae feeds. We hope that is Brief will contribute for the emergence and expansion of projects and ventures in this sector.
