Greece’s Competition Commission on Thursday announced it was imposing fines totaling 680,000 euros against the country’s five biggest fish farming enterprises and warned against price fixing cartels that limit competition by citing the economic crisis hitting the country.

The market watchdog called on the five companies to terminate their practices, although it acknowledged that the fines were reduced, taking into consideration the special conditions prevailing in the country.

The Competition Commission fined Nereus Fish Farms SA with 273,582 euros, Selonda with 146,339 euros, Dias Fish Farms with 119,015 euros, Aquaculture Farms with 42,905 euros and Hellenic Fish Farms with 96,044 euros.
