The use of palm oil in aquaculture feeds for salmonid species
In this overview, our current knowledge and research being conducted on the use of palm oil in the commercial feeds for cold-water salmonid species such as Atlantic salmon and rainbow trout will be highlighted. Salmonids have a high requirement for lipid as a source of energy and n-3 polyunsaturated...
