A Review of the Status of the Use and Potential to Use Micro and Macroalgae as Commercially Viable Raw Material Sources For Aquaculture Diets
Abstract:
The vast majority of global aquaculture production (c. 88%1) is either marine plants, filter feeding shellfish, or omnivorous/freshwater finfish with a low requirement for marine protein and lipid derived feeds. However, the remaining small (but important to Scotland and other EU27 states) percentage are carnivorous finfish species, which require commercially formulated feeds that contain high levels of protein and lipid. The traditional source of the raw materials to manufacture these diets has been fishmeal and fish oils derived from the feed fish capture sector – largely to ensure that the amino acid and fatty acid components are nutritionally suitable for the finfish species being cultivated.
This issue was discussed at a recent Marine Conservation Society workshop - “Feeding the Fish of the Future – Alternative choices for aquafeeds”2, which highlighted the increasing need for the aquaculture feeds of the future to rely on alternative, non-marine or nontraditional marine ingredients. The event also highlighted the growing interest and concern for the future formulation of aquaculture feeds by policy makers, environmental NGO’s, feed companies, and retailers, including the extent to which algae, as a “marine” source, could potentially be a viable ingredient for aquafeeds.
