Obviously not a 'catch' but I found a hatchet fish washed up on the beach at LJ Shores. LJ Shores is right in from the canyon but still strange to find deep water fish on the beach.

A buddy of mine found a King-of-the-salmon floating near Cat Harbor on the back side of Catalina. That's a weird ass fish.

Can't say it's super rare but I've caught banded guitar fish in deep south bay.
