Zapata Corporation is a holding company that operates primarily in the food-related segment. Zapata operates its food related business through its 61% owned subsidiary, Omega Protein Corporation, which produces and markets a variety of products produced from menhaden (herring-like fish found in commercial quantities in the U.S. coastal waters of the Atlantic Ocean and Gulf of Mexico), including regular grade and value-added specialty fish meals, crude and refined fish oils and fish solubles. Omega's fish meal products are used as nutritional feed additives by animal feed manufacturers and by commercial livestock producers. Omega operates a fleet of fishing vessels as well as four processing plants. Omega's crude fish oil is sold primarily to food producers in Europe, and its refined fish oil products, which are high in nutritionally desirable Omega-3 fatty acids, are used in a variety of foods for human consumption, as well as in aquaculture feeds and certain industrial applications.
