cies varied considerably from 1965: Carp 

 landings were up 394,800 pounds; catfish 

 catches were down 227,000 pounds; sheeps- 

 head production was off 1,777,100 pounds; 

 white bass harvest increased 165,600 pounds; 

 yellow perch landings rose 1,566,800 pounds; 

 and yellow pike production declined 64,600 

 pounds. 



Spacecraft May Help Increase 

 Fish Catch 



Space vehicles of the future may be used 

 to help man catch more fish from the oceans. 

 Under Secretary of the Interior Charles F. 

 Luce said October 5 to the Atlantic States 

 Marine Fisheries Commission at Portland, 

 Me. Mr. Luce noted that BCF is looking in- 

 tensively to new developments to increase 

 the efficiency of the U. S. fishing fleet. 



"One interesting aspect of this is the pos- 

 sible use of spacecraft to obtain oceanograph- 

 ic and fishery data," Mr. Luce added. "Ex- 

 periments and feasibility studies underway 

 now in the use of spacecraft include deter- 

 mination of sea surface temperature using 

 infrared detectors, radar detection of sur- 

 face water disturbances caused by surface 

 feeding fish schools, estimation of wave 

 height by radar, detection of chemical fish 

 trails at the surface of the water left by mi- 

 gratory schools of fish. . .and direct spotting 

 of large marine mammals by high resolution 

 photography. American astronauts have been 

 briefed on fishery and oceanographic research 

 and they have already supplied us with much 

 useful information." 



Under Secretary Luce predicted that the 

 total consumption of commercial fish and 

 fishery products in the United States, both 

 from domestic and imported sources, will 

 jump to nearly 28 billion pounds a year by 

 the year 2000. The present consumption is 

 about 12 billion pounds. 



The Department of the Interior's Fish and 

 Wildlife Service is the official research agen- 

 cy for the Atlantic States Marine Fisheries 

 Commission- -the Nation's oldest interstate 

 marine fishery organization, founded by in- 

 terstate agreement in 1941. 



TV Camera Shows Tests at 

 45,000 Feet 



A television camera has been developed by 

 its Instrumentation Department that shows ef- 

 fects of tests conducted at simulated depths 

 down to 45,000 feet, says the U. S. Naval Ocean- 

 ographic Office. The camera operates from 

 the outside of a high-pressure test -and -eval- 

 uation vessel and relays a clear picture to a 

 TV monitor. The picture shows what is hap- 

 pening to instruments having to withstand 

 pressures in the ocean's deepest known 

 parts --UP to 20,000 pounds per square inch. 



The TV camera is light and compact enough 

 to be handled easily by one man, but the test 

 vessel weighs 18 tons and has a plug-type 

 cover weighing 4,000 pounds. The test de- 

 vice is capable of accepting instruments up 

 to eight feet in length. 



The closed -circuit TV monitoring system 

 clearly shows how instruments will react 

 when subjected to pressures claimed by man- 

 ufacturers. "Some instruments disintegrate, 

 others collapse, but many perform as claim- 

 ed," William L. Bryan of the Naval Oceano- 

 graphic Office states, "it is better to test 

 our instruments here in a laboratory, rather 

 than risk having a failure at sea. Savings in 

 time and money are great, in addition to 

 averting any serious injuries to personnel." 



"Aluminaut" Recovers Instruments 

 From Ocean Bottom 



"The deepest known search and recovery 

 mission has been successfully accomplished 

 for the U. S. Navy by the Aluminaut, the 

 world's deepest diving submarine," its own- 

 er, the Reynolds Co., reports. Under con- 

 tract to the Naval Oceanographic Office 

 (NOO), the 51 -foot, 6-man, all-aluminum 

 sub set a record by performing a 3,200 -foot 

 ocean-bottom search for oceanographic in- 

 struments lost over a year ago off St. Croix, 

 Virgin Islands. The sub recovered the 2,100- 

 pound package of instruments in 3,150 feet 

 of water in mid-October. 



The Reynolds Co, considers the search 

 part of the mission the most difficult. On 

 the first dive, October 12, the Aluminaut lo-
