Greenpeace is calling for China’s fishing companies to be ‘reined in’ after research revealed at least 74 fishing vessels owned and operated by four Chinese Distant Water Fishing (DWF) companies have been exposed for fishing illegally in prohibited fishing grounds in West Africa.

According to the research, there are 82 cases of demonstrated and potential cases of illegal, unreported and unregulated (IUU) fishing activities and gross tonnage fraud in Senegal, Guinea, Guinea-Bissau and Ghana, and includes China’s largest DWF company, China National Fisheries Corporation (CNFC). The cases date 2000-2014, with the oldest case as far back as 1988.

“While China extended a hand in friendship during the Ebola outbreak, rogue Chinese companies were unlawfully exploiting West Africa’s marine environment,” said Rashid Kang, head of Greenpeace East Asia’s China Ocean Campaign. “They were taking advantage of weak enforcement and supervision from local and Chinese authorities to the detriment of local fishermen and the environment.”

China’s Distant Water Fishing industry constitutes less than 0.1% of its global overseas investment. “But unless the government reigns in this element of rogue companies, they will seriously jeopardise what the Chinese government calls its mutually-beneficial partnership with West Africa,” added Mr Kang.

The most recent cases were witnessed by Greenpeace ship MY Esperanza, which sailed through the Exclusive Economic Zones (EEZs) of Senegal, Guinea-Bissau and Guinea between 26 October and 21 November 2014. In Guinean waters alone, the ship documented 16 illegal fishing activities by 12 Chinese-flagged or owned vessels, making an average of one Chinese IUU case every two days while MY Esperanza was at sea.

In addition, recent Greenpeace Africa findings show that Chinese Distant Water Fishing vessels are illegally falsifying vessel gross tonnage in Senegal, Guinea-Bissau and Guinea in 2014. China National Fisheries Corporation (CNFC), for instance, under-declared gross tonnage for 44 of the 59 vessels it operates in the three West African countries, which not only evades licensing fees, but also illegally gives these higher volume vessels access to prohibited areas.

Greenpeace says while the Chinese government is starting to eliminate some of the most destructive fishing practices in its own waters, the loopholes in existing policies lead to a double standard in Africa. “If China wants to be a genuine friend of Africa, it should follow the path of EU’s Common Fisheries Policy, which is slowly rectifying the EU’s own history of irresponsible fishing in the region,” said Ahmed Diamé, Greenpeace Africa Ocean Campaigner.

Over the last 15 years, Greenpeace has also investigated and exposed illegal and destructive fishing practices by EU, Korean and Russian fishing vessels in Africa. As a result of declining domestic fish stocks, Chinese companies have expanded their fishing operations in Africa from 13 vessels in 1985 to 462 vessels in 2013. Many of the companies operating in the region have history of illegal fishing activities.

Between 2000-2006 and 2011-2013, there were at least 183 documented IUU fishing cases in just six West African countries (Gambia, Guinea, Guinea-Bissau, Mauritania, Senegal and Sierra Leone) – all of which involved Chinese owned or flagged vessels with at least 31% of them have engaged in illegal fishing activities more than once. Greenpeace says most of these vessels are bottom trawlers, one the most destructive fishing vessels in the industry.
