A recent report has revealed that Spanish fleets are overfishing the seas, resulting in dangerously low fish stocks
According to the environmental charity Greenpeace, the country's boats are failing to implement sustainable fishing policies.
With some of the nation's largest fishing ships capable of hauling in 3,000 tonnes of tuna in one trip, the threat could soon spiral out of control.
Farah Obaidullah, oceans campaigner for Greenpeace, commented: "If Europe wants fish tomorrow, Spain must stop overfishing today. Ministers gathering here should immediately take steps to reverse Spain's ocean destruction at this critical time."
The news comes as a study in the journal Nature Communications revealed that there has been "an extraordinary decline" in fishing stocks as well as "profound" changes to ecosystems.
This has resulted in lower catches being brought in by UK fishermen. Even Spanish trawlers are now being forced to look further afield, as Greenpeace claims the country's boats are heading as far away as Antarctic and African waters.
