But the “fisherman” is really a French navy seaman disguised in a T-shirt, cap, and sunglasses – a member of an unusual multinational training exercise to combat crime in the Gulf of Guinea.
Illegal fishing, piracy, and hostage-taking haunt the vast bay lying off West Africa, whose coastline runs from Liberia in the west to Gabon in the south.
According to the European Union, the Gulf of Guinea is the “worst-affected region” in the world for unauthorised fishing. In 2016, around a third of all catches, a haul worth about 1.5 billion euros (RM7.3 billion), were illegal, it says.
In a survey of sea piracy in 2017, the International Maritime Bureau found that of 16 incidents around the world when a vessel came under fire, seven occurred in the Gulf.
In late February, the French patrol boat Lavallée took part in exercises with naval vessels from central African countries over five days, an operation dubbed “African Nemo”.
These exercises, held several times a year, are designed to be realistic.
In one, not far off São Tomé and Príncipe, sailors from the island country were ordered to arrest the crew of a Chinese fishing boat in the shape of the Lavallée.
A São Toméan naval officer led his men in boarding the foreign vessel for an inspection and thorough search, which resulted in the arrest of the pretend fisherman for pillaging local fish stocks.
The “fishermen” put up a fuss, rowdily complaining of the heat and doing their best to make life more difficult for their captors.
One São Toméan sailor carefully treated a make-believe injury sustained by a fisherman, setting his arm in a sling.
Once the exercise was over, it was time for an assessment. The São Toméan sailors realised they needed to beef up safety precautions while boarding a vessel and improve ways of searching a suspect.
Another scenario envisaged an operation against pirates. Aboard a Gabonese patrol boat that sailed from Gabon’s capital Libreville, participants practiced how to conduct the mission without breaching international maritime law.
“This type of exercise is informative and places us in real-life situations,” said the vessel’s commander, Sub-Lieutenant Gaël Mbanda.
“They enable us to pinpoint our weaknesses in equipment and personnel.”
Rules for terms of intervention and sharing tasks were signed in June 2013 by leaders from the 15-nation Economic Community of West African States (ECOWAS) and from the 10-nation Economic Community of Central African States (ECCAS).
This accord, signed in Cameroon and known as the “Yaoundé Process”, has led to stronger cooperation over some 6,000 kilometres (3,700 miles) of African coasts and the adjacent waters, Maritime Security Review reported in June 2017, when EU logistical support began.
Despite the political steps forward, huge practical challenges remain, given the sheer volume of fish stocks stolen in a vast area of water.
“Illegal fishing amounts to a quarter of the value of African exports,” said Lionel Kinadjian, the representative of the UN’s Food and Agriculture Organization in Gabon.
Senior French naval officer Captain Emmanuel, whose second name was withheld for security reasons, also pointed to a shift in tactics by pirates.
“(They) have moved on from ‘bunkering’ – the theft of goods stored aboard a vessel – to an increase in the taking of hostages for ransom,” he said.
