The SMCA protects marine life by limiting the removal of marine wildlife from within its borders. Swami's SMCA prohibits take of all living marine resources except: recreational take of coastal pelagic species, except market squid by hand-held dip net only, is allowed. Commercial take of coastal pelagic species, except market squid, by round haul net only is allowed. Take pursuant to beach nourishment and other sediment management activities and operation and maintenance of artificial structures inside the conservation area is allowed per any required federal, state and local permits, or as otherwise authorized by the department.

History

Tijuana River Mouth SMCA is one of 36 new marine protected areas adopted by the California Fish and Game Commission in December, 2010 during the third phase of the Marine Life Protection Act Initiative. The MLPAI is a collaborative public process to create a statewide network of protected areas along California's coastline.

The south coast's new marine protected areas were designed by local divers, fishermen, conservationists and scientists who comprised the South Coast Regional Stakeholder Group. Their job was to design a network of protected areas that would preserve sensitive sea life and habitats while enhancing recreation, study and education opportunities.

The south coast marine protected went into effect 2012.
