Cabinet approves India’s accession to the Southern Indian Ocean Fisheries Agreement, expanding high-seas fishing and governance rights
Why this matters
India’s approval to accede to SIOFA links fisheries policy with maritime presence, blue-economy growth and ocean governance. It gives Indian vessels a legal route to seek authorised high-seas fishing opportunities, but also creates stronger duties for science, monitoring and conservation.
In plain words
This decision places India inside the governance system for non-migratory fisheries in the high seas of the Southern Indian Ocean. SIOFA is a regional fisheries agreement: countries jointly decide how certain fish, squid, molluscs and crustaceans may be studied, caught and conserved beyond national maritime zones. It does not regulate tuna and other highly migratory species, which fall mainly under arrangements such as the Indian Ocean Tuna Commission.
India has participated since 2022 as a Cooperating Non-Contracting Party, meaning it could cooperate with SIOFA but had limited influence over decisions. After the accession process is completed, India will become a Contracting Party, enabling fuller participation in the Scientific Committee, Compliance Committee and Meeting of the Parties. Indian-flagged vessels and enterprises may then seek authorisation to fish for resources such as squid, toothfish and alfonsino, subject to SIOFA rules, scientific advice, vessel controls and catch arrangements.
The simplest analogy is joining a neighbourhood association: membership may open access to a shared facility, but it also means accepting common rules, inspections and maintenance costs. For India, the gain is not an automatic fishing quota; it is lawful access combined with a seat at the rule-making table. The move can support seafood exports, marine research and maritime awareness, provided fishing capacity grows more slowly than scientific knowledge and enforcement capability.
Key facts
- India has been a Cooperating Non-Contracting Party to SIOFA since 2022 and will now become a Contracting Party.
- Indian-flagged vessels and enterprises can undertake authorised fishing for squid, toothfish, alfonsino and other non-migratory stocks in SIOFA’s jurisdiction.
- Membership enables fuller participation in scientific, compliance and decision-making bodies, including access to stock assessments and research programmes.
- India will participate in measures against illegal, unreported and unregulated fishing, including the High Seas Boarding and Inspection scheme.
- SIOFA covers fishery resources such as fish, molluscs and crustaceans in the Southern Indian Ocean, while excluding highly migratory species regulated elsewhere.
How we got here
SIOFA was signed in Rome in July 2006 and entered into force on 21 June 2012. Its framework is rooted in the United Nations Convention on the Law of the Sea, 1982, and related international fisheries instruments that balance the freedom to fish on the high seas with duties of conservation and cooperation.
The organisation became operational through successive Meetings of the Parties, scientific work and conservation and management measures. Its area covers fishery resources in the Southern Indian Ocean, but excludes highly migratory species listed in Annex I of the United Nations Convention on the Law of the Sea and sedentary resources falling under coastal-State jurisdiction under Article 77(4).
India has been a Contracting Party to the Indian Ocean Tuna Commission since 1996 for highly migratory tuna and tuna-like resources, while it joined SIOFA as a Cooperating Non-Contracting Party in 2022. The December 2025 Guidelines for High Sea Fisheries created a domestic policy context for expanding Indian fishing beyond waters where Indian vessels generally operate. The Cabinet approval on 14 October 2026 begins the formal move towards full SIOFA membership; authorisation, vessel compliance and scientific obligations will still govern actual fishing.
The bigger picture
International
From observer-like cooperation to rule-making
As a Cooperating Non-Contracting Party, India had limited participation in SIOFA decision-making. Contracting Party status would give India a fuller role in the Meeting of the Parties and subsidiary bodies dealing with science and compliance. This matters because fishing opportunities are shaped not merely by geography but by conservation measures, reporting rules and authorised-vessel lists. India can now influence rules affecting the Southern Indian Ocean rather than only respond to them. The step also complements India’s existing membership of the Indian Ocean Tuna Commission, whose main focus is highly migratory tuna and tuna-like species.
Membership converts India from a limited participant into a fuller rule-maker in Southern Indian Ocean fisheries governance.
Economic
Blue-economy opportunity with a capability test
Squid, toothfish and alfonsino are commercially valuable resources, but SIOFA membership itself does not guarantee a quota, profitable voyages or immediate exports. India will require suitable vessels, cold-chain facilities, processing capacity, skilled crews, satellite communication and insurance for long-distance operations. The opportunity is therefore an ecosystem challenge, not simply a licensing decision. If developed responsibly, high-seas fishing can diversify seafood supply chains and raise value addition. If pursued without stock knowledge and cost discipline, it could create financial losses and pressure for excessive fishing.
The agreement opens a legal opportunity; India must still build economically viable and environmentally responsible deep-sea capacity.
Environmental
Deep-sea resources are slow to recover
Several SIOFA resources are deep-sea species that may grow slowly and mature late. SIOFA scientific material describes alfonsino and toothfish as long-lived, late-maturing fishes, making overfishing especially difficult to reverse. Fishing can also affect vulnerable marine ecosystems through bottom contact, bycatch and lost gear. India’s participation in stock assessments and research programmes can improve decisions, but only if vessels submit reliable catch and effort data. The precautionary approach should therefore guide expansion: where evidence is weak, fishing pressure should remain conservative until stock condition and ecosystem effects are better understood.
The environmental test is whether access expands faster than scientific evidence and ecosystem safeguards.
International
High-seas security and illegal fishing control
India’s participation in the High Seas Boarding and Inspection Scheme links fisheries governance with maritime security. Boarding, inspection, vessel identification and reporting can deter illegal, unreported and unregulated fishing and improve awareness of activity in a strategically important ocean space. However, enforcement on distant waters requires trained inspectors, interoperable information systems, legal procedures and coordination between fisheries, the Coast Guard, Navy and foreign authorities. India must avoid treating inspection powers as symbolic; their credibility will depend on consistent evidence collection, due process and follow-up action against violations.
Fisheries enforcement can become a practical instrument of maritime domain awareness, but only with institutional coordination.
Social
Reconciling distant-water expansion with coastal livelihoods
India’s fishing communities may benefit from new employment, processing demand and export markets, but gains will not automatically reach small-scale fishers. Public support for distant-water capacity should therefore be linked to transparent access, worker safety, fair contracts and investment in coastal landing and processing infrastructure. The policy must also prevent a shift of subsidies and institutional attention away from near-shore livelihoods, where many families remain vulnerable to depleted stocks, storms and pollution. A just transition means complementing high-seas fishing with sustainable aquaculture, value addition and fisher welfare.
A blue-economy strategy is credible only when distant-water gains complement, rather than displace, coastal fishing communities.
The big debate
Will SIOFA accession strengthen India’s blue economy, or risk adding pressure to fragile deep-sea ecosystems?
For
- Legal access can diversify seafood supply, support exports and create incentives for Indian deep-sea vessel and processing capacity.
- A seat in scientific and compliance bodies lets India shape conservation rules instead of remaining a passive rule-taker.
- High-seas inspection and reporting can improve maritime awareness and deter illegal fishing in the Southern Indian Ocean.
Against
- Deep-sea species such as toothfish and alfonsino may recover slowly, while scientific data and stock assessments remain incomplete.
- Long-distance fishing may favour large firms, concentrate benefits and weaken attention to small-scale coastal fishers.
- Expanded fleet capacity can encourage political pressure for higher catch limits before enforcement systems mature.
On balance. Accession is strategically sound because rule-making presence is better than exclusion from a shared ocean space. However, the economic case is conditional: India should authorise fishing incrementally, tie access to verified science and monitoring, protect coastal livelihoods, and treat conservation compliance as the price of membership rather than an optional supplement.
For or against?

Prelims quick-fire
- International. SIOFA was signed in Rome in 2006 and entered into force on 21 June 2012 under its multilateral fisheries framework. Do not confuse SIOFA’s entry-into-force date with India’s 2022 cooperating status.
- Term. SIOFA covers fish, molluscs, crustaceans and other sedentary resources, excluding highly migratory species and coastal-State resources. Tuna is not the defining SIOFA resource category; highly migratory stocks are regulated elsewhere.
- International. India became a Cooperating Non-Contracting Party to SIOFA in 2022 and received Cabinet approval for accession in October 2026. Cabinet approval begins accession; it should not automatically be read as completed treaty accession.
- Body/Institution. The Indian Ocean Tuna Commission regulates highly migratory tuna and tuna-like species; India has been its Contracting Party since 1996. IOTC and SIOFA have overlapping ocean geography but different resource mandates.
- Geography. The SIOFA Agreement Area lies in the Southern Indian Ocean high seas, beyond national maritime jurisdiction. High seas are not the same as a country’s exclusive economic zone.
- Body/Institution. SIOFA includes scientific and compliance bodies, supported by Meetings of the Parties and conservation measures. Scientific advice does not itself create a fishing quota; authorisation remains rule-dependent.
- International. High Seas Boarding and Inspection procedures are designed to help combat illegal, unreported and unregulated fishing. Inspection powers operate through agreed procedures and do not erase flag-State responsibilities.
- Environment. SIOFA scientific material identifies alfonsino and toothfish as long-lived, late-maturing deep-sea fishes. Late maturity generally increases vulnerability to rapid overfishing and slow recovery.
What should happen
- Adopt a science-first national licensing system for SIOFA vessels, with conservative catch limits, electronic reporting, observers and periodic review. Authorised access should be matched by India’s own evidence on stock status, bycatch, gear impacts and vessel performance. SIOFA Scientific Committee work programme and SIOFA Agreement, 2006
- Create an integrated high-seas compliance cell linking the Department of Fisheries, Indian Coast Guard, Indian Navy, ports and seafood regulators. Distant-water enforcement requires one chain for vessel tracking, inspection reports, prosecutions and international information-sharing. SIOFA High Seas Boarding and Inspection Scheme
- Build a coastal value-addition strategy covering cold chains, processing, traceability, worker safety and fair access for small and medium enterprises. Domestic employment and export value will rise only when fish is safely landed, processed and transparently traced in India. Pradhan Mantri Matsya Sampada Yojana
- Use regional research partnerships to improve stock assessments, tagging, ecosystem mapping and climate-risk analysis before scaling fleet capacity. Many deep-sea species are long-lived and late-maturing, so precaution requires better knowledge of age, distribution and recruitment. SIOFA Scientific Committee research programmes
- Align SIOFA implementation with Sustainable Development Goal 14 and the precautionary approach to ocean resources. India’s blue-economy expansion should demonstrate that access, livelihood creation and marine conservation can be pursued together. Sustainable Development Goal 14
Jargon, demystified
- Southern Indian Ocean Fisheries Agreement (SIOFA)
- A multilateral agreement governing conservation and sustainable use of selected fisheries in the Southern Indian Ocean high seas. Signed in 2006 and in force from 21 June 2012.
- Regional Fisheries Management Organisation (RFMO)
- An international body through which countries jointly manage fisheries in a defined ocean region, using science and common rules. SIOFA and the Indian Ocean Tuna Commission have different mandates.
- Cooperating Non-Contracting Party (CNCP)
- A country that cooperates with an agreement’s rules without yet enjoying the full rights and decision-making status of a Contracting Party. India held this status in SIOFA from 2022.
- High seas
- Ocean areas beyond national maritime zones where no single country has territorial sovereignty, but international law still imposes duties. High seas do not mean an unregulated or law-free space.
- Exclusive Economic Zone (EEZ)
- A maritime area extending up to 200 nautical miles where a coastal State has special rights over natural resources. EEZ rights differ from sovereignty over territorial waters.
- Highly migratory species
- Marine animals that travel across national waters and high seas, requiring cooperation across wide ocean areas. Tuna and tuna-like species are generally handled through the Indian Ocean Tuna Commission.
- Illegal, unreported and unregulated fishing (IUU fishing)
- Fishing that violates rules, is hidden from authorities, or occurs without effective conservation and management controls. SIOFA compliance and inspection measures seek to deter it.
