I see from the blatts (or at least from the Cork Examiner) that there is much free food to be had in the Tralee Ship Canal, which has, it is said, “Literally millions of sprat and mackerel” as well as eels, baby ray and shrimp. According to the story,
Kerry County Council said engineers were meeting yesterday to find a resolution and to organise a clean up.
Perhaps a call to Captain Birdseye?

So what’s the problem? It’s not like these fish are impeding the progress of any ships, is it?
Or has there been a late rush of luxury yachts navigating the broken sealock?
