Oceanographic surveys of the Gulf of Mexico have 

 furnished important information on currents, circula- 

 tion, temperature, salinity, plankton, and bottom sedi- 

 ments, all of which affect directly or indirectly the 

 spawning and distribution of shrimp and finfishcs. In 

 cooperation with the National Aeronautics and Space 

 Administration, the Navy, and the Geological Survey, 

 BCF is studying how spacecraft oceanography may be 

 applied to commercial fisheries. With such advanced 

 techniques, it may be possible to detect oceanic phe- 

 nomena that concentrate fishes and to pinpoint the 

 location of fish schools for the benefit of the commer- 

 cial fishing fleets. 



Laborators' and office space are available for a 

 limited number of visiting scientists. Arrangements for 

 space should be made by writing to the Laboratory 

 director. 



Biologists raised white shrimp in experimental ponds from about 

 yi inch in total length to about 4/2 inches in 5 weeks. When 

 placed in the pond, the shrimp were so tiny that more than 

 43,000 were needed to weigh 1 pound. They grew so rapidh 

 that in 5 weeks it took onh' 79 shrimp to weigh 1 pound. These 

 shrimp had been reared through the lar\al stages from eggs 

 spawned and hatclied in tlie BCF Biological Laboratory, Galveston.
