Hi Togo, some pollack and bass can be found from March but they are harder to find then and the pollack are smaller. If I haven't been in the water in winter then by March I can't wait any longer for fresh fish. Crabs and lobsters are around then too of course.
I normally wear a 7mm suit but this year I'm going with a 5mm. Most UK divers wear 5mm and water temperatures are similar here.
I get a few scallops but the only place I know with a lot of them is a marine reserve where taking them isn't allowed!
Don't know about vis in Dublin area but in summer here and in calm weather, it varies from 7m to 14m. In spring the plankton keeps it lower.
I do some rod fishing for mackeral as I love to eat them and bass fishing passes the time when I can't dive.
