The chum run was relatively substantial throughout the seasor, £i\d.ng satisfactory- 

 proportionate escapement and a pack of 3^3,000 cases. To offset the lack of fish of the 

 summer season^ there was ujiusual activity in utilizing the fall catches of both seines 

 and gill nets, with the result that over 100,000 cases were processed, plus a substantial 

 Increase of frozen products. 



The newly established gill net fishery from Red Bay to Lake Bay on the northeast 

 coast of Prince of Wales Island produced somewhat less than hoped. Contrary to expecta- 

 tions, the Lake Bay fish were not intercepted, resulting in an underutilization of these 

 sockeye. Portland Canal was more productive in its first year of gill netting,, accounting 

 for 110,000 salmon, primarily chums. In comparison, the long established seine fishery 

 in Portland Canal accounted for only 20,757 fish, over half of ^ich were pink salmon. 



The escapement in all /jnerican tributaries to 

 Portland Canal was satisfactory. 



Ihe several gill net fisheries made a 

 significant contribution to the 1957 pack. 

 Gill net caught chum salmon, alone, numbered 

 about 500,000 fish and made up about 20 percent 

 of the total production in Southeastern Alaska. 



Two of the research projects being con- 

 ducted in Southeastern Alaska are directed 

 toward developing reliable means of predicting 

 the abundance of adult pink salmon. One method 

 involves obtaining an index of abundance of the 

 young fry migrating from their parent streams. 

 Ihe second method, perhaps more desirable 

 because it eliminates consideration of fresh- 

 water and early saltwater mortalities, is an 

 estimate of abundance of the fingerllng in 

 marine feeding areas and migration routes. 



A total of 12 fry sampling stations was 

 operated during the spring of 1957 • They were 

 located, with few exceptions, on streams in the 

 southern inside waters of the Panhandle. Rec- 

 tangular fry traps, thoroughly tested in 1956, 

 were used to establish a more reliable index 

 of abundance. Ccinparative data are available 

 for only k streams; in 3 of these the fry 

 migration was much larger in 1957 than in 195^, 

 and in the other it was very low. Among all 

 of the streams the migration was Judged to be 

 good to excellent in 7 and fair to poor in the 

 balance. Ttie largest catches and estimated 

 migrations occxirred at Anan Creek, Naha and 

 Wilson Rivers, and Herman Creek. 



The enumeration of the fingerllng pink 

 salmon was conducted at 115 fish traps, \riiere 

 the watchmien cooperated by keeping daily 

 records of young salmon observed within the 

 pots and splllers. In general, the records 

 obtained provide a relative index of abundance. 

 Ihls was the third year in which an index of 

 fingerllng abundance was compiled, and adult 

 returns for two yeaxs are now available for 

 analysis. The abundance index, consisting of
