I'd be happy with one really good fish for the night.
It can be fustrating. Two years ago I was fishing Black Rock in the wee morning hours. I had a few fish, nothing special, all on local squid. There was a guy fishing the bowl to the left/east of the point. All pre-dawn I saw him going back and forth between the water line and I guess he's bait bucket (saw his light that is). When the sun came up I saw he was really into fish! Maybe it was his bait (he was using mac chunks) or he was just in the honey hole that morning. I couldn't see any specific structure that would hold fish there and not at the point. But that's fishing!
ps- Every try up North around Settler's Rock or Mansion Beach? (the Maze is way too hairy to get into at night!)
