Caulerpaceae

The natural range covers the tropical and subtropical waters of the World Ocean. On an industrial scale, cultivation is most active in Southeast Asian countries such as the Philippines, Vietnam, and Japan. The crop prefers shallow, well-lit areas with sandy or muddy bottoms, which are effectively simulated in artificial ponds.

Botanically, Caulerpa is a complex system consisting of stolons (horizontal runners), rhizoids that anchor into the substrate, and assimilators that function like leaves. Its uniqueness lies in its high regenerative capacity: even a small fragment of a stolon can give rise to a new plant, which serves as the foundation for its propagation in commercial farming.

Environmental requirements include a stable water temperature between 25–30 degrees Celsius and high light intensity. In controlled environments, specialized nutrient solutions containing nitrogen and phosphorus are often added to boost biomass production. A critical aspect of cultivation is maintaining consistent salinity levels and ensuring the cleanliness of flow-through systems.

The economic use of Caulerpa is multifaceted: it is consumed as a delicacy known as "sea grapes" and utilized in pharmacology due to its high concentration of bioactive compounds, antioxidants, and polysaccharides. Furthermore, it serves as a valuable ingredient in animal feed and specialized aquaculture diets.

• High rate of organic matter biosynthesis.
• Capability for vegetative propagation via fragmentation.
• Rich in iodine and essential trace minerals.
• Resilience to various pathogens when salinity is maintained.

The primary threats to the crop include fungal infections and the uncontrolled growth of epiphytic algae, which block light access. Pests can include certain species of sea snails and crustaceans that graze on the algae tissues, necessitating strict phytosanitary protocols in closed-system farming operations.
