Global supplies of fishmeal have remained static but demand continues to grow due to the growth of the aquaculture industry worldwide. Fishmeal has historically been the feed ingredient of choice but increased demand for formulated feeds has necessitated the identification and use of alternate protein sources. An expanding knowledge of nutrient requirements, nutrient availability, nutrient composition of feed ingredients and the availability of feed additives and novel ingredients have made the reduction or elimination of fishmeal use in feeds for finfish a reality. Despite advances in nutritional knowledge and feed manufacturing, fishmeal continues to be used at relatively high levels in fish feed formulations and is an issue that needs to be addressed.
