Historically, animal-derived components like fish meal and fish oil have been the primary protein and lipid ingredients in aquaculture nutrition. However, excessive harvesting has led to a decline in their availability, resulting in significant price hikes. Spirulina has emerged as a superior alternative to other algae like Chlorella due to its high growth potential and efficient carbohydrate synthesis, making it ideal for large-scale cultivation. Consequently, feed manufacturers are now prioritizing Spirulina as a sustainable, plant-based substitute for traditional fish meal to minimize the overhead costs of aquaculture production.
