The health benefits of omega-3 long chain polyunsaturated fatty acids (omega-3 LC-PUFA) are recognized worldwide. The traditional
source of omega-3 LC-PUFA is fish. However, global consumer needs cannot be supplied by the current global fish harvest. Therefore, new
sources of omega-3 LC-PUFA have to be found. Microalgae are producers of omega-3 LC-PUFA and a potential alternative for seafood.
Other sources of omega-3 LC-PUFA include krill oil, calamari oil and genetically engineered land plant crops.
