  ALASKA 
  FISHERIES 
  AND 
  FUR 
  INDUSTRIES, 
  1913. 
  

  

  Operations 
  were 
  confined 
  chiefly 
  to 
  the 
  month 
  of 
  September, 
  when 
  

   collections 
  aggregated 
  5,280,000 
  humpback 
  eggs. 
  

  

  Dm'ing 
  the 
  month 
  of 
  May, 
  1913, 
  observations 
  were 
  made 
  in 
  a 
  

   limited 
  way 
  by 
  the 
  superintendent 
  of 
  the 
  Yes 
  Bay 
  station 
  for 
  the 
  

   purpose 
  of 
  obtaining 
  information 
  as 
  to 
  the 
  number 
  of 
  young 
  sockeye 
  

   salmon 
  passing 
  into 
  Yes 
  Bay. 
  At 
  6 
  o'clock 
  on 
  the 
  evening 
  of 
  May 
  4 
  a 
  

   small 
  net 
  was 
  placed 
  in 
  Yes 
  River, 
  just 
  above 
  tide 
  water, 
  at 
  a 
  point 
  near 
  

   the 
  cannery. 
  One 
  end 
  of 
  the 
  net 
  was 
  made 
  fast 
  ashore 
  and 
  the 
  other 
  

   end 
  was 
  attached 
  to 
  a 
  large 
  rock 
  only 
  3 
  feet 
  out 
  from 
  the 
  same 
  shore. 
  

   At 
  8 
  o'clock 
  on 
  the 
  following 
  morning 
  this 
  small 
  section 
  of 
  net 
  con- 
  

   tained 
  1,310 
  yearling 
  sockeye 
  salmon, 
  averaging 
  3 
  inches 
  in 
  length. 
  

   The 
  river 
  at 
  this 
  point 
  is 
  about 
  20 
  feet 
  wide. 
  The 
  next 
  night 
  a 
  net 
  

   was 
  set 
  near 
  the 
  foot 
  of 
  the 
  lake 
  where 
  the 
  river 
  at 
  the 
  time 
  was 
  about 
  

   50 
  feet 
  wide. 
  The 
  net 
  in 
  this 
  instance 
  covered 
  about 
  10 
  feet 
  of 
  the 
  

   stream. 
  It 
  should 
  be 
  noted 
  that 
  the 
  lead 
  line 
  was 
  about 
  a 
  foot 
  from 
  

   the 
  bottom. 
  The 
  next 
  morning 
  575 
  yearling 
  sockeye 
  salmon 
  were 
  

   taken 
  from 
  the 
  net. 
  On 
  May 
  16 
  this 
  net 
  was 
  again 
  set 
  near 
  the 
  foot 
  

   of 
  the 
  lake, 
  but 
  owing 
  to 
  very 
  high 
  water 
  only 
  50 
  yearling 
  sockeyes 
  

   were 
  caught. 
  All 
  fish 
  taken 
  in 
  the 
  three 
  sets 
  were 
  in 
  excellent 
  

   condition. 
  

  

  The 
  fact 
  that 
  a 
  small 
  piece 
  of 
  net 
  only 
  3 
  feet 
  long, 
  set 
  in 
  a 
  stream 
  

   20 
  feet 
  wide, 
  will 
  catch 
  1,310 
  sockeye 
  yearlings 
  in 
  one 
  night 
  would 
  

   seem 
  to 
  be 
  very 
  good 
  evidence 
  that 
  the 
  aggregate 
  number 
  of 
  young 
  

   salmon 
  thus 
  moving 
  to 
  the 
  sea 
  during 
  the 
  entire 
  period 
  of 
  the 
  spring 
  

   migration 
  is 
  of 
  highly 
  satisfactory 
  proportions. 
  That 
  the 
  Yes 
  Bay 
  

   hatchery 
  is 
  a 
  potent 
  factor 
  in 
  this 
  result 
  almost 
  goes 
  without 
  sa3^ng, 
  

   as 
  practically 
  all 
  of 
  the 
  sockeyes 
  passing 
  into 
  Yes 
  Lake 
  are 
  spawned 
  

   at 
  the 
  hatchery.
