separated in the catch and is grouped with 

 the pink salmon, 



Japanese biologists estimate that in 

 recent years gill net-caught fish have com- 

 prised 75 percent to 80 percent of the total 

 commercial landings and longline-caught 

 fish from 25 percent to 20 percent in the 

 eastern Hokkaido fishery. Table 2 shows 

 the total annual catch of salmon in percent- 

 ages by gear and by species for all shore 



fisheries, such as the eastern Hokkaido 

 salmon fishery, Japjui Sea pink salmon fish- 

 ery, and the Okhotsk Sea coastal fishery. 

 It can readily be seen from this table that 

 the percentages of salmon taken by longline 

 gear show significant increases over a 6- 

 year period, 1952 to 1957: pink salmon 

 from 4.8 to 24.5 percent, chum salmon from 

 less than 1 percent to 8.3 percent, and all 

 species from 3.6 to 20.4 percent.
