A demand has been made for an urgent response from the Maritime and Coastguard Agency (MCA) after a reported incident between a Spanish fishing vessel and a local trawler.
It comes after video footage was posted online showing a Spanish gill-netter vessel allegedly attempting to damage the propeller of a local whitefish trawler.
Isles MP Alistair Carmichael has written to the MCA’s chief executive Brian Johnson demanding action.
Mr Carmichael said: “These allegations are extremely concerning and demand an immediate response from the MCA.
“This is not the first time that we have had reports of aggressive and dangerous behaviour by Spanish trawlers in these waters.
“This footage brings home just how dangerous such behaviour can be.
“This is more than an issue of fisheries management, this is about basic maritime safety. The MCA must act accordingly. Fishermen should not expect harassment or unsafe practices from other vessels, no matter the political context.”
