On a clear morning in the eastern Mediterranean, a Gaza fisherman can see where he is not allowed to go. The horizon is not the boundary. The Israeli navy gunboat is. And on most days, that gunboat sits somewhere between three and six nautical miles from shore — well short of the limit that international negotiators wrote into the Oslo II Accord in 1995, and well inside the space where Palestinian families built livelihoods across generations.
The gap between what the law permits and what the navy enforces is not ambiguous or contested. It is documented, consistent, and measurable. It has also helped collapse one of Gaza’s oldest industries.
What Oslo II Actually Promised
The legal baseline is Article IV of Annex I to the Israeli-Palestinian Interim Agreement on the West Bank and the Gaza Strip — known as Oslo II — signed in Washington on 28 September 1995. The text is explicit: Palestinian fishing vessels would be permitted to operate up to 20 nautical miles from Gaza’s coastline. That zone, stretching westward into the Mediterranean, was intended to give Gaza’s fishing fleet access to deeper, more productive waters where larger pelagic species — tuna, swordfish, larger sardine shoals — move through seasonally.
The agreement did not grant a favour. It reflected customary international practice: coastal fishing communities typically have access to territorial and adjacent waters as a matter of livelihood and subsistence right. The Geneva Convention’s protections for civilian populations, and the broader framework of international humanitarian law, reinforce the obligation not to collectively punish a civilian population by severing its food-production capacity.
The 20-mile zone was never implemented for a single sustained day.
The Enforced Reality: 3 to 6 Miles, and Often Less
Since Israel imposed its naval blockade on Gaza — tightened comprehensively after 2007 — the permitted zone has been unilaterally contracted by Israeli military authorities, with no legal process and no Palestinian consent. The limit has shifted repeatedly: at various points set at 6, then 3, then temporarily extended as a political gesture, then contracted again. As of the period immediately preceding October 2023, the nominal limit stood at 6 nautical miles for most of Gaza’s coast, with a slightly extended zone off the south. Even those numbers, however, do not describe what fishermen actually experience on the water.
Al-Mezan Center for Human Rights and the Palestinian Centre for Human Rights (PCHR), both Gaza-based organisations with field monitoring programmes, have documented hundreds of incidents in which Israeli navy vessels fired upon — with live ammunition, rubber-coated bullets, or water cannon — fishing boats operating inside the declared limit. Al-Mezan’s reporting across multiple years records fishermen shot, wounded, killed, and arrested while their GPS coordinates placed them within the permitted zone. Boats have been seized, nets confiscated, engines destroyed. In some documented cases, fishermen were stripped, made to swim to navy vessels, and detained for hours before release.
PCHR’s weekly field updates, maintained consistently over more than a decade, form one of the most granular records of the enforcement pattern. They show that the effective fishing zone — the space where a fisherman can work without near-certain risk of fire — has frequently been closer to two or three nautical miles, regardless of the officially stated limit.
The Economics of a Shrinking Sea
The consequences for Gaza’s fishing industry are not incidental. They are structural and severe. Palestinian Central Bureau of Statistics (PCBS) data show that the fishing sector, which once supported an estimated 3,000 to 4,000 active fishermen and many thousands more in related trades — processing, ice supply, net repair, transport, retail — has been reduced to a fraction of its former scale.
The UN Conference on Trade and Development (UNCTAD) has repeatedly noted in its reports on the Gaza economy that the fishing sector’s potential output is fundamentally constrained by access restrictions, not by the absence of fish. The waters beyond the enforced limit contain the stock. Inside three to six miles, near-shore waters are heavily fished out. Catch volumes have fallen drastically compared to pre-blockade levels, with some estimates suggesting a decline of more than 50 percent in annual catch weight compared to the early 2000s, though precise figures vary by source and year.
OCHA oPt has documented the human consequences: fishing families pushed into deeper poverty, reliance on UNRWA food assistance rising within the fishing community itself — the bitter irony of people whose profession is food production being unable to feed their families adequately.
Firing Inside the Zone: Documented Incidents
The point that most directly challenges Israeli government framing is not the gap between 20 miles and 6 miles. It is the pattern of enforcement inside whatever limit is currently declared.
Al-Mezan’s documentation includes repeated incidents in which fishermen were targeted at 2, 3, or 4 nautical miles — distances that fall inside even the most restrictive version of the permitted zone. In one illustrative category of cases, fishermen report being fired upon without warning, with navy vessels approaching rapidly before shots were discharged. Nets and equipment losses from such incidents run into thousands of dollars per event — catastrophic for households operating with minimal capital.
Israeli military spokespersons have at various times described such incidents as responses to vessels approaching security infrastructure or crossing unmarked buffer lines. The documentation gathered by Al-Mezan and PCHR, including GPS data, witness testimony, and medical records from injured fishermen, does not consistently support those characterisations.
What Remains of an Industry
Gaza’s coastline runs approximately 40 kilometres. It once sustained a way of life. The fishing families of Gaza City’s port neighbourhood, of Khan Younis and Rafah’s coastal margins, carried knowledge of currents, seasons, and species across generations. That knowledge has not disappeared, but the conditions to apply it have been systematically removed — not by the sea, but by a naval enforcement policy that treats a civilian livelihood as a security variable to be adjusted or eliminated by military order.
Oslo II’s 20-mile promise was made by negotiators at a table. The Israeli navy’s gunboat enforces a different geography entirely. Between those two numbers — 20 and 3 — lies the distance between a written commitment and a lived reality that Gaza’s fishermen navigate every morning they push their boats into the water.
