Fishing is allowed on the pier without a fishing license, although all other regulations apply including size/bag limits and report cards. However, a fishing license is required to fish on the beach and in the surf. Fishing in the Tijuana River Mouth State Marine Conservation Area and all other marine protected areas is restricted.
If fishing in the surf, you must be 150 feet away from any swimmers and surfers. You must also be 300 feet away from either side of the pier. On the pier, you cannot fish between the posted signs.
Possessing a speargun that is armed, cocked, or drawn on the beach is also not allowed. You must be a thousand feet outside of the shoreline to use a speargun.
