These groups, the free-living and the parasitic copepods, are generally caught with different methods. On the Al batross, the parasitic copepods were mostly taken from fish, although cope pods could be parasitic on most any marine animal, even whales. The free living copepods were taken primarily by plankton nets, which would catch pelagic as well as occasional bottom dwelling copepods. In some plankton Figure 1.—U.S. Fisheries Steamer Albatross under partial sail in Alaska (from Towns samples, free-swimming stages of par end, 1901). asitic copepods were encountered.
