Feed – Introduction

What’s the alternative?

Industry meeting demand for new ingredients

T

HE growth of the global aquaculture industry provides obvious commercial opportunities for fish feed manufacturers but also challenges. Further expansion depends on the sustainability of the sector and that involves a search for high quality alternatives to finite marine ingredients. Fishmeal and fish oil remain essential compo- Right: Finite resources nents of aquafeeds for most fed species for at least some part of the production cycle, as Neil Auchterlonie of IFFO, the Marine Ingredients Organisation, points out (page 40). But all the big feed companies have embraced research into other sources of nutrition and many of these innovations are now being put to the test. Following the groundbreaking production of omega-3 fish oils from genetically modified camelina plants – by scientists at Stirling University and Rothamsted Research in 2015, a new GM feed trial was launched last year. Feed giant Cargill believes it could provide a sustainable alternative source of EPA/DHA omega-3 fatty acids from a type of canola. In feeding trials conducted with salmon in Chile, Cargill was able to completely replace fish oil in feed rations with oil from EPA/DHA canola. ‘As a fish feed producer, we need to reduce our dependency on marine resources,’ said Einar Wathne, president of Cargill Aqua Nutrition. ‘This new canola can create tremendous opportunities across the global food and feed markets, and we believe it is critical for the growth of aquaculture.’ The new canola, which is genetically engi-

neered to make long chain omega-3 fatty acids, will offer a more sustainable alternative as it eases pressure on marine resources. Testing and regulatory approval for both the canola and the EPA/DHA enhanced canola oil is underway and it is expected to reach the market some time after 2020. ‘Cargill’s EPA/DHA omega-3 plant based product is the only one we know of with a clear path to commercialisation in the industry,’ said Mark Christiansen, managing director for Global Edible Oil Solutions-Specialties at Cargill. Wathne said trials using feeds containing the GM oil have been positive. ‘We have made full-scale tests throughout the life cycle of salmon in Chile. It has worked well and, more importantly, is safe and good for the fish,’ he said. Cargill, which took over the feed company Ewos in 2015, is also collaborating with the US biotech company Calysta to produce the novel protein FeedKind. Over the following pages we look at some of the other exciting developments in the feed market, from maggot meal to microalgae, as well as cutting edge research from our leading scientists. FF
