Powdered seaweed or seaweed flour is widely used as an ingredient in terrestrial and aquatic feedstuffs, usually from a single species. Peer reviews over the years have demonstrated a range of benefits including, improved resistance to viral and bacterial pathogens and promoting gut health.
Ocean Harvest Technology Ltd, a Scottish company, have recently launched a new seaweed derived feed product called ‘Oceanfeed®’, a chemical free balanced mix made from several varieties of sustainably harvested seaweeds.
Recent trials carried out by Ocean Harvest and EWOS (UK) Ltd carried out at Loch Eilort, 40 miles north of Fort William on the Scottish west coast on mixed sex salmon smolts has proved to be very successful. The trail was carried out on two different feeds an organic feed and Oceanfeed. The feeds were fed to the same species of salmon and monitored.
The results of this trial were encouraging in many ways. The Oceanfeed® diet seemed to result in improvements in Growth Rate, FCR, Mortalities, Fish Flesh Flavour and Texture and lower Sea lice infestation. With different species of seaweed that are carefully formulated to a complex mix with targeted performance improvements that will give a better yields of healthy products that taste significantly better. Of importance in today's climate is the ability to introduce to the public, the use of sustainable ingredients that help create, a healthier happier and tastier product.
For those interested in the technical data and full results of the experiment in the article it will be available in Aquafeed online from the of November 1, 2010.
