Eels are very plentiful in the loch system - every single sampling site that we went to pretty much had eels and the sheer volume of it was a bit of a surprise, we can't exclude the possibility that there's a giant eel in Loch Ness but we don't know whether these samples we've collected are from a giant beast or just an ordinary one - so there's still this element of 'we just don't know.'.
