Food from the Sea 



— conducted the world's largest fish tagging program to delineate 

 Atlantic menhaden migrations and provide a basis for estimating 

 natural and fishing mortality ; 



— improved assessment of salmon distribution in the northeastern 

 Pacific and the efTect of industrially induced thermal variations on 

 survival of salmonid and other species in the Columbia River ; and 



— improved fishery forecasting services in the eastern Pacific. 



2. Processing and marketing programs, accounting for 13 percent of the 

 FY 1 970 budget. In 1 968, BCF : 



— inaugurated a program of seafood merchandising workshops ; 



— developed an insulated leakproof container for transporting fresh 



fish; and 

 — improved techniques for mechanical peeling of northern shrimp. 



3. Advanced technology programs, accounting for 8 percent of the FY 

 1970budget.ini 968, BCF: 



— developed modifications to trawl gear for New England groundfish 

 which demonstrated a significant increase in catch ; 



— developed a new wing trawl to reduce unwanted fish and debris from 

 catches by the Pacific northwest shrimp industry; 



— delineated the calico scallop resource off the east coast of Florida 

 which is expected to create a major new fishery ; 



— tested sonar and aerial photographic techniques for detecting and as- 

 sessing pelagic fish schools in the Gulf of Mexico; 



— increased significantly the catches of alewives and chubs in Lake 

 Michigan through use of an electrified trawl system and developed 

 and tested surface nets for removal of dead alewives; and 



— developed pond catfish harvesting equipment. 



4. Economic research programs, accounting for 2 percent of the FY 1970 

 budget. In 1968, BCF 



— analyzed the impact of imports on the New England groundfish in- 

 dustry and the U.S. fishmeal industry; 



— assisted in initiation of an anti-dumping study of imports which com- 

 pete closely with New England fishery products ; and 



— initiated systems analysis for the New England haddock fishery based 

 on previous systems analysis sponsored by the Marine Sciences 

 Council.* 



5. International activities. — Details of some of the most significant inter- 

 national fishing programs for which the Bureau has provided the scientific 

 data and technical personnel are described in Chapter III. This type of ac- 

 tivity accounts for about 1 percent of the FY 1970 budget. 



In addition to these marine science programs, the Bureau of Commercial 

 Fisheries is also responsible for three financial assistance programs which
