AECD-3446 -130- Section xy FISH by Arthur D, Welander METHODS The collections of fish, as in former years (see UWFL* Reports 7, 16, and 19) were made in shallow water on reefs inside the atoll during low tide periods, ~ These shallow water collections were supplemented by deep water collections using traps and hook andline fishing, and by night fishing with a small dip net. Shallow water collections, using the rotenone from derris root, were made on the lagoon side of Bikini, Enyu, Amen, Erik, Boro, and Namu Islands of Bikini Atoll; on the lagoon side of Igurin, Rigili, Japtan, Engebi, Runit and Eberiru Islands of Eniwetok Atoll; and the lagoon side of Likiep Island at Likiep Atdll, Trap fishing was carried on with some success in the Target Area in 180 feet of water and less successfully in 20 to 30 feet of water near the reef between Bikini and Amen Islands, near Bokon Island, Bikini Atoll, and in some areas of Eniwetok Atoll, Trolling by means of feather or bone jigs produced a number of tuna, mackerel and barracuda from Ruji Pass, Bikini Atoll; and night fishing using a light produced a numberof planktonic forms and planktonic feeders such as herring, silversides and halfbeaks. collecting data.
