Thanks to everyone with tips for catching crab at Balboa Pier in Newport. Used a few small crab hoop net devices, baited with assorted raw meat. Only caught a few very small crab (I think rock crab?), but it was a fun learning experience.
Total of 4 crab over a couple of trips. Take a look at the video here:
