I've never worked that section of the coast, but the most common low intertidal species are Neogonodactylus oerstedii and Pseudosquilla ciliata. State regulations apply. You can't collect in protected areas and you can't take live rock or coral. However, it is possible to collect stomatopods in public access, non-protected areas. In some cases, I've found that a fishing license is required.
