Other Activities ; On the southbound and northbound portions of the trip, oceano- 

 graphic data were taken to establish the strengths and positions of the major ocecin 

 currents, as well as other biological data. 



" JOHN R. MANNING " TO CONTINUE INVESTIGATIONS ON TUNA PURSE SEINING ( Cruise No. 

 VI ) : In order to continue investigations on the occurrence of tunas in certain areas 

 in the Central Pacific Ocean and to determine the feasibility of using a standard 

 West Coast tuna purse seine to catch them, the John R. Manning left Honolulu the 

 latter part of March. This vessel of the Service's Pacific Oceanic Fishery Investi- 

 gations will cruise the waters surrounding the Line Islands from Kingman Reef to 

 Jarvis Island, and is expected to return on or about May 12. 



Gear development studies are to be made during the operation of this standard 

 tuna purse seine. Minor variations are to be effected whenever possible on the fish- 

 ing grounds. Major changes will be recorded for future planning of a purse seine 

 that is better adapted to conditions encountered in the Central Pacific Ocean. 



Secondary objectives of the cruise will be to record and collect hydro graphical, 

 biological, and meteorological data related to the occurrence of fish. 



Ocean Perch (Rosefish)" Designated by Service 

 as Name for Rosefish 



Hereafter the Fish and Wildlife Service will use the term ocean perch ( rosefish ) 

 to designate that species of fish ( Sebastes marinus) which has been listed as rose- 

 fish ( ocean perch ) . Ocean 

 perch is taken in large 

 quantities in North Atlan- 

 tic waters, usually being 

 landed as "redfish.'.' It is 

 marketed in filleted form 

 throughout the United 

 States, almost universally, 

 as ocean perch . It is the 

 principal species landed at 

 Gloucester, Massachusetts, 

 and also at several ports 

 in Maine. 



The Service proposed 

 the name rosefish for Se- 

 bastes marinus during World 

 War I, when it was practically unkixjwn. 

 1935. 



It was not taken in quantity until about 



Recently the National Fisheries Institute, at the request of two fishery asso- 

 ciations in New England, asked the Service to reconsider the name used for Sebastes 

 marinus in Service publications. The Service recognized several years ago that the 

 name ocean perch was in wide commercial use and at that time changed the official 

 name from rosefish to rosefish ( ocean perch) . To bring the conmon name in line with
