Fishermen, ocean biologists and the fisheries ministry are furious about a Greenpeace action in the North Sea, where the environmental organisation on Monday erected huge wooden effigies of seahorses on the Klaver bank.

Greenpeace is drawing attention to the fact the Klaver bank needs protection and has sunk large stone blocks into the sea to hold the four-metres tall statues.
Fishermen say their nets can easily catch on the stone blocks and that vessels could be capsized.
Discussions are taking place to turn the fish-rich Klaver bank into an ocean reservation but Greenpeace says these are taking too long.
‘We have given the coordinates for the stone blocks to the authorities so fishermen can avoid the area,’ a spokesman told Trouw.
