Species Under Cultivation

The emphasis here is on aquatic animal production, but as previously indicated, aquatic plants comprise nearly 25% of global aquaculture production by weight. Many hundreds of thousands of people are involved, worldwide, in aquatic plant production. The quantity of brown seaweeds, red seaweeds, green seaweeds, other types of algae, and miscellaneous aquatic plants such as watercress, water chestnuts, and ornamental plants produced in 1996 was estimated at more than 7.7 million metric tons (6). Several species of macroalgae are listed in Table 3. Microscopic algae and cyanobacteria are sometimes marketed as food or as a nutritional supplement (eg, Spirulina sp.). In addition, an undocumented quantity of algae (mostly of the single-celled variety) is produced for use as food for filterfeeding aquatic animals (primarily mollusks and zooplankton). Planktonic organisms such as rotifers are reared on algae and then used to feed the young of crustaceans and fish that do not accept prepared feeds.

Animal aquaculture is concentrated on finfish, mollusks, and crustaceans. Sponges, echinoderms, tunicates, turtles, frogs, and alligators are all being cultured, but production is insignificant in comparison with the three prin-
