I have caught them, but never targeted them.
I am usually good for a couple at Doc's or Purdy when targeting SRCs or Silvers on small tube flies or Clousers during the year. I have a buddy that does target them. He fishes the Day Island kelp beds with lead core and tube flies. Although his catch ratio isn't great, some the bigger Blackmouth he has caught have been in the 10# range. He seems to catch a lot of small feeders in the 18"-20" range in the first two hours of the day. After that, he's trolling gear around.

I don't think there is a big following for Blackmouth on a fly, but when the Nookie is in.... well that is another story and a zipper lip.
