Capital-light by design
The infrastructure is already deployed. India’s commercial fishing fleet - approximately 200,000 motorised vessels operating from hundreds of ports along the Indian coastline - goes to sea every day regardless of whether THALWAG exists. The observation network does not need to build vessels, ports, or transit routes. It needs to equip a fraction of an existing fleet with low-cost sensors and build the data pipeline behind them.
The cost per observation, at fleet scale, is a fraction of any comparable programme built on dedicated research infrastructure. Research vessels cost upward of ₹5-15 crore per day to operate. Argo floats cost approximately ₹10-15 lakh each and produce a single vertical profile every ten days before drifting out of the target region. A THALWAG sensor on a fishing vessel costs a fraction of either, operates daily, and stays in the target geography because that is where the fleet fishes.
The network scales with fisher participation, not capital expenditure. Adding capacity means enrolling more vessels, not procuring more infrastructure.
