India's accession to SIOFA marks a shift from an EEZ-centric to a high-seas fisheries strategy. Discuss the opportunities and the sustainability concerns.

The high seas make up about 65% of the global ocean. Distant-water fleets dominate fishing there, led by China with 21%, while Indian vessels mostly fish within 60–80 NM of the coast [1]. India has now been approved to join the Southern Indian Ocean Fisheries Agreement (SIOFA), moving up from Cooperating Non-Contracting Party (2022) to full Contracting Party [1]. This gives the move beyond the EEZ a legal footing, but the gains will last only if the fishing is sustainable.

Opportunities

• Economic: Legal access to high-value non-migratory stocks such as squid, toothfish and alfonsino. This adds to India's tuna access under the IOTC (member since 1996) and advances the Blue Economy [1].
• Livelihoods: The Letter of Authorisation (LoA) is mandatory for high-seas fishing, and cooperatives and fish farmer producer organisations (FFPOs) get priority for it [2]. LoAs were issued in 2026, when the Odisha Deep Sea Fishing Mission was also launched [3].
• Strategic: India gets full voting rights on SIOFA's binding Conservation and Management Measures. It also joins the High Seas Boarding and Inspection Scheme, which improves maritime domain awareness in the Indian Ocean Region [1].
• Scientific: Access to SIOFA's stock assessments and research programmes [1].

Sustainability concerns

• Fragile ecology: Deep-sea species like toothfish grow slowly. Bottom fishing can also damage corals and sponges on the seabed. Both call for a precautionary approach.
• Compliance burden: India must commit to science-based limits and to fighting IUU fishing (illegal, unreported and unregulated fishing) [1]. LoA holders must follow RFMO catch limits and bycatch rules [2]. Boarding works both ways, so one non-compliant Indian vessel can hurt India's standing.
• Capacity gap: India's fleet mostly fishes close to shore [1]. The duties of membership start now, but the catch will come only after India has deep-sea vessels.
• Equity: Deep-sea fishing needs a lot of capital, so large firms may crowd out artisanal fishers.

The accession gives India market access, influence in the Indian Ocean and scientific data, but these gains depend on fishing within ecological limits. India should fund exploratory surveys and send Indian scientists to SIOFA's Scientific Committee. It should also help cooperatives pool compliant vessels and replicate Odisha's mission in other coastal states. That would make the high-seas strategy fair to fishers and consistent with SDG 14 (Life Below Water).
