If anyone hasnt seen this yet it's well worth a look, especially the second part.
Pretty interesting bit on the seal population in the 1st part though.
Here's the description: Coastal waters, looks at the history of our inshore coastal waters. Viewed through the life experiences of retired curach fishermen Peadar Ó Conghaile from Inis Oírr and Danny Sheehy from West Kerry, we see the changing nature of man’s relationship with the sea as we encounter seals, dogfish, pollack, flounder and wrasse (with their highly complicated sex lives)....
The bit about wrasse and their "highly complicated sex lives" is an understatement. Ive always heard the phrase "think like a fish"...but I think thinking like these would be going abit too far.
this is the link to the player in English, you'll have to click on the documentaries archive on the right hand side, then scroll down until you see Farraigí na hÉireann. Otherwise it will be repeated on Sunday night on TG4.
