Published on

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.
