Carlsbad Aquafarm

Carlsbad Aquafarm traces its roots back to incorporation of Carlsbad and the building of the Cabrillo Power Station in the early 1950’s. Back then an aquaculture research facility was established along the southwest shore of the Agua Hedionda Lagoon to determine how best to improve and sustain the ecological health of the lagoon. Researchers concluded that shellfish would be the keystone species needed upon which a healthy lagoon could support a diversity of marine life, shorebirds and wildlife.
