While the Laboratory program is not the 

 only shark tagging program being conducted, 

 it is the principal one on the United States 

 east coast. Sportsmen are assisting Bureau 

 biologists in the program and success of the 

 study depends on cooperation from fishermen 

 in recovering tags. Largely through these 

 sportsmen's efforts, over 2,500 tagged sharks 

 are now at liberty in the Atlantic Ocean. 



The yield of scientific information from 

 these studies depends on tag recoveries. 

 Since sharks are not fished commercially to 

 any extent along the east coast, it is impor- 

 tant that fishermen are on the lookout for the 

 tagged specimens. In order to acquaint fish 

 ermen with the study, the Sandy Hook Ma- 

 rine Laboratory has distributed reward post- 

 ers at docks, tackle shops, marinas, and oth- 

 er places in different areas. The Laboratory 

 hopes to cover the coast from Maine to Texas 

 with this information so that tag recoveries 

 will increase as more people become aware 

 of the program. 



An important world-wide shark program 

 is being conducted by the American Institute 

 of Biological Sciences under the direction of 

 Stewart Springer, U. S. Bureau of Commer- 

 cial Fisheries, Stanford University, Stanford, 

 Calif, In addition to the United States pro- 

 grams, biologists in Canada, South Africa, 

 Norway, Australia, and New Zealand also 

 have an interest in shark migration studies. 

 Earlier tagging programs, particularly in 

 Australia, have produced major contributions 

 to understanding the life history of commer- 

 cially valuable sharks in that area.

M/V " Oregon " Cruise 108 (AprlTTS-SO, 

 1966): A two-week exploratory fishing cruise 

 along the southeastern coast of the United 

 States was completed April 30, 1966, by the 

 exploratory fishing vessel Oregon , operated 

 by the Bureau of Commercial Fisheries, U. S. 

 Department of the Interior. Objectives of the 

 cruise were to obtain seasonal catch data on 

 the offshore brown shrimp grounds south of 

 Cape Kennedy, and to survey the outer shelf 

 area between Charleston, S. C, and Sebastian 

 Inlet, Fla., with shrimp trawls and scallop 

 dredges. Gear used in the trawling transects 

 were 40- and 6 -foot flat shrimp trawls rig- 

 ged on 6- and 8 -foot chain doors. 



No grooved shrimp concentrations were 

 located south of Cape Kennedy. Only scat- 

 tered brown (Penaeus aztecus) and pink (P. 

 duorarum ) shrimp were caught through the 

 25- to 30-fathom depth levels where commer- 

 cial concentrations were located during the 

 winter of 1965. 



Small quantities of rock shrimp ( Sicyonia 

 brevirostris) were uniformly distributed from 

 Charleston to central Florida in depths of 15 

 to 50 fathoms. South of Cape Kennedy catches 

 increased to 12 to 65 pounds an hour of 21-25 

 count (heads-on) rock shrimp. 



Several good indications of bottomfish con- 

 centrations were observed during the cruise. 

 Two -hour drags with 40 -foot trawls off Day- 

 tona Beach in 25 to 30 fathoms yielded 300 to 

 1,300-pound catches of i-pound spot ( Leio -
