This episode looks at the lives of the people of Magdalena Bay along the Pacific side of Baja, California, and how they live off the bounty of the Mangroves. Mangroves are trees with root support systems that can establish themselves in the saltwater estuaries of the bay. Bountiful fisheries result directly and indirectly from the presence of the Mangrove. The Mangrove thrive in the bay, a wealth of sea life - fish, clams, lobster, crabs, shrimp, and scallops - thrive among the Mangrove, and the people harvest the sea life as their means of making a living. The program also offers a brief look at aquaculture (farming the seas for fish) during a visit to a tuna farm.
