Around Dingle the Lighthouse seems to be the place to be, especially for the thornbacks. Also if after conger the marina itself is a good bet.
If you're willing to travel the cliffs at ventry are amazing for pollock, wrasse etc. Just park at chuan pier and a thirty minute walk will take you to the mark in question; but a warning, these cliffs are extremely dangerous.
Try this website, it should put you on the right track, and if after flounder and bass just give me a pm.
