Choosing the best species of algae to farm depends on the intended use, local climate, available resources, and the chosen farming method. Species like spirulina and chlorella are popular for nutritional supplements because they grow quickly, have high protein content, and thrive in controlled environments. Nannochloropsis is often selected for omega-3 production, while species like Dunaliella are valued for beta-carotene.
For biofuel production, species with high lipid content, such as Botryococcus braunii, are preferred. Macroalgae like kelp or nori are ideal for food and fertilizer markets and can be grown in coastal areas. The choice also depends on water type, with some species requiring freshwater and others thriving in saltwater or brackish conditions.
