Flood lamp and TV camera serve as tools in the study of the schooling and feeding habits of fish and their reaction to various stimuli. The University of Miami in Florida maintains its Audio-Visual Observation Sta tion off Bimini, in the Bahamas. Silvery mar gate fish flash by the installation. Manatee grass covers the sea bed. Fisheries officials forecast remote-controlled sub marines to pull nets. Some fishermen already use electricity to attract menhaden to suction hoses. With bubble curtains, fish have been corralled in waters too deep for conventional seines. but longer stays-has been used by Capt. Jacques-Yves Cousteau in the Red Sea.* This July, too, Dr. Bond will attempt the first large job to be performed at depth. His four-man team will live for two or three weeks at the foot of a Texas tower off Ber muda while they inspect and clean its base 193 feet down-and perform scientific experi ments as well. They will live in a steel cylinder. Once we have proved that man can live in the deep for long periods, we must give our attention to the kind of house he will occupy. Fortunately, he will not require the heavy metal spheres and cylinders now in use. Dry Work Space at Sea Bottom If inside and outside pressures are equal ized, the undersea house might well be made of heavy-duty rubber, and thus be easily transportable when deflated. It can be de signed in a balloonlike shape with a small "door" in the bottom. Or it can be made with an open bottom like a tent. Pressure of the air or gases inside would keep the sea out. *See "At Home in the Sea," by Capt. Jacques-Yves Cousteau, NATIONAL GEOGRAPHIC, April, 1964. 797
