Aqua Colloids cultivates Kappaphycus alvarezii, a high-yield red seaweed ideal for carrageenan extraction. Cultivation happens across coastal Tamil Nadu, India, and Jaffna, Sri Lanka. We use the raft-based method — a low-impact, rope-seeding system on floating bamboo or PVC rafts. It is eco-monitored and scalable within coastal fishing communities.
Seaweed Cultivation

Our farmers receive training and technical know-how for sustainable seaweed cultivation. AquaAgri offers a buy-back guarantee at pre-agreed prices, ensuring income security. The company works directly with coastal communities, especially women cultivators, ensuring ethical and traceable sourcing. Continuous on-ground support is provided through an extended field team.

Our Core Focus

Spinosum
It is a type of seaweed cultivated in Indonesia. It contains a substance called carrageenan that plays a very important role as a stabilizer, thickener, gel maker, and emulsifier.

Seaweed is farmed.
In India’s tropical waters, only three seaweed species are widely cultivated for commercial use. Historically, we focused on Kappaphycus—now we’re adding Spinosum to diversify cultivation and strengthen supply chains. This expansion boosts resilience and opens new industrial opportunities in food, pharma, and personal care.
