Japanese pirates went under the radar

Four Japanese vessels which carried out pirate fisheries in Western Sahara waters have turned off their location transponders. WSRW sends repeat protest to Japan government.

shoei_maru_no7_28.10.2014_350.jpgIn October Western Sahara Resource Watch (WSRW) discovered three (and later, a fourth) Japanese vessels in the waters offshore occupied Western Sahara. WSRW asked the Japanese government to intervene to stop the practice. No response has yet been received by WSRW, nor has WSRW observed any intervention from the Moroccan government.

The fisheries bear all signs to be what is characterised internationally as Illegal, Unreported, and Unregulated (IUU) fishing.

The Moroccan environmental control over international and national fleets in Western Sahara’s coastal waters has always been inadequate. No state recognises Morocco’s claim to sovereignty over the territory, and Morocco has itself not laid claim to its waters.  Even if this particular instance of fishing had been granted by the Moroccan government, it would still have been in violation of international law. WSRW has found no evidence that the vessels have been granted permission by the Government of Morocco to fish off the south coast of the occupied territory.  Certainly, they have not received permission of the Saharawi Republic, the only government to have asserted claims to those waters.  By all indications, the four vessels have shown up unannounced and without any permission.

chioymaru_no18_28.10.2014_350.jpgDuring the morning of 28 October 2014, eleven days after WSRW first protested the fisheries, the four vessels turned off its AIS transponders. The vessels are:

'Shoei Maru No 7' (IMO number 9120023), last registered transponder signal at 28 Oct 05:47
'Koryo Maru 51' (IMO number 8915990), last registered transponder signal at 28 Oct 05:35
'Chiyo Maru No 18' (IMO number  9016521), last registered transponder signal at 28 Oct 04:13
'Taiwa Maru No. 88' (IMO number 9053488), last registered transponder signal at 28 Oct 08:05

An AIS transponder is part of the communication system that all vessels carry on board to identify where they are and which routes they are taking on sea. It is not unusual that vessels engaged in pirate fisheries go under the radar by turning off their responders.

koryo_maru_no51_28.10.2014_350.jpgEach of the four missing vessels are longliners, and the sailing tracks they displayed visually and on radar reveal that they are fishing for tuna, most likely the “bigeye” species, which is priced on Japanese/European markets at approximately $9 (Euro 6) a kilo. As each of the four vessels have cargo capacity of 400 tonnes, the value of the Japanese illegal fishing expedition into Saharawi waters would be worth approximately Euro 9 million, providing they manage to fill the cargo capacity.

The International Union for the Conservation of Nature (IUCN) considers tuna species in the Atlantic Ocean to be “threatened”.  The organization responsible for tuna in the Atlantic, the International Commission for the Conservation of Atlantic Tunas (ICCAT) has also expressed concern about the sustainability of tuna fishing. The United Nations Food & Agriculture Organization (UNFAO) has condemned such “rogue” or “pirate” IUU fishing as damaging to fish stocks and the orderly allocation of fisheries yields among states which participate in regional fisheries management organisations.  

WSRW today sent another letter of protest to the Japanese government. Download the letter here.

WSRW initially had reported that there are three Japanese longliners involved in the practice. The confirmed correct number is four.




Morocco occupies the major part of its neighbouring country, Western Sahara. Entering into business deals with Moroccan companies or authorities in the occupied territories gives an impression of political legitimacy to the occupation. It also gives job opportunities to Moroccan settlers and income to the Moroccan government. Western Sahara Resource Watch demands foreign companies leave Western Sahara until a solution to the conflict is found.
EU Court cases on Western Sahara for dummies


It's not easy keeping up with all the different legal proceedings relating to Western Sahara. For the sake of clarity, here's an overview of the five different cases at the Court of Justice of the European Union.
Stand up for the Gdeim Izik 25!


Leading activists from Western Sahara are condemned to sentences ranging from 20 years to life imprisonment in connection to a mass protest in 2010 denouncing the Saharawi people’s social and economic marginalization in their occupied land; the Gdeim Izik protest camp.

Report: Moroccan green energy used for plunder


At COP22, beware of what you read about Morocco’s renewable energy efforts. An increasing part of the projects take place in the occupied territory of Western Sahara and is used for mineral plunder, new WSRW report documents.
