Marseille blamed the decline on reduced volumes in the Asia-Europe trade, which accounts for around 60 percent of its box traffic, and rolling strikes by dock workers protesting government plans to privatize container handling later in the year.
Strikes were also largely responsible for a 15 percent fall in 2008 traffic to 848,000 TEUs from over one million TEUs the previous year as thousands of containers were diverted to Barcelona, Genoa and other Mediterranean ports.
The port was at a standstill on March 19 as dock workers joined a 24-hour general strike to protest the government's economic policies.
Total traffic in February fell 21 percent from a year ago to 12.7 million tonnes with all sectors showing declines, including general and break bulk cargo down 50 percent. This was an improvement on January when traffic slumped 24 percent to a 10-year low of 6.5 million tonnes.
