  Afognak. 
  

  

  At 
  the 
  Afognak 
  station 
  during; 
  1912 
  the 
  take 
  of 
  red 
  salmon 
  eggs 
  

   numbered 
  14,689,470. 
  In 
  addition, 
  3,271,740 
  humpback 
  eggs 
  were 
  

   taken. 
  Plants 
  of 
  sockeye 
  fry 
  made 
  principally 
  during 
  February 
  and 
  

   March, 
  1913, 
  aggregated 
  12,551,100. 
  The 
  loss 
  during 
  the 
  period 
  of 
  

   incubation 
  was 
  14| 
  per 
  cent. 
  So 
  much 
  trouble 
  was 
  caused 
  by 
  heavy 
  

   deposits 
  of 
  fine 
  sediment 
  in 
  the 
  fry 
  troughs 
  that 
  it 
  was 
  deemed 
  best 
  

   to 
  plant 
  the 
  young 
  fish 
  early 
  in 
  the 
  season 
  at 
  places 
  about 
  the 
  lake 
  

   where 
  the 
  streams 
  did 
  not 
  wash 
  in 
  quantities 
  of 
  ash. 
  The 
  take 
  of 
  

   eggs 
  was 
  greatly 
  lessened 
  by 
  the 
  loss 
  of 
  spawning 
  fish 
  following 
  the 
  

   fall 
  of 
  ash 
  from 
  the 
  Katmai 
  volcanic 
  eruption 
  June 
  6 
  to 
  9, 
  1912. 
  

   This 
  same 
  influence 
  has 
  undoubtedly 
  been 
  responsible 
  in 
  considerable 
  

   measure 
  for 
  the 
  lessened 
  take 
  during 
  1913, 
  when 
  but 
  10,989,000 
  sock- 
  

   eye 
  eggs 
  were 
  obtained. 
  The 
  take 
  of 
  humpback 
  eggs 
  was 
  larger, 
  

   numbering 
  13,900,000. 
  While 
  the 
  propagation 
  of 
  sockeye 
  salmon 
  is 
  

   more 
  to 
  be 
  desired 
  when 
  spawning 
  fish 
  are 
  available, 
  there 
  is 
  never- 
  

   theless 
  a 
  very 
  good 
  field 
  in 
  Alaska 
  for 
  the 
  propagation 
  of 
  humpbacks. 
  

   It 
  has 
  been 
  shown 
  that 
  the 
  propagation 
  of 
  cohos 
  is 
  not 
  advisable, 
  at 
  

   least 
  in 
  conjunction 
  with 
  sockeye 
  operations, 
  as 
  many 
  of 
  the 
  young 
  

   cohos 
  remain 
  in 
  fresh 
  water 
  for 
  a 
  year 
  and 
  prey 
  upon 
  the 
  sockeyes. 
  

   The 
  humpbacks, 
  however, 
  go 
  to 
  sea 
  soon 
  after 
  hatching. 
  

  

  No 
  fish-cultural 
  operations 
  were 
  undertaken 
  at 
  Malena 
  Lake 
  this 
  

  

  year, 
  as 
  an 
  inspection 
  during 
  the 
  month 
  of 
  August 
  disclosed 
  that 
  the 
  

  

  spawning 
  creek 
  at 
  the 
  head 
  of 
  the 
  upper 
  lake 
  was 
  almost 
  filled 
  with 
  

  

  volcanic 
  ash. 
  

  

  Eagle 
  Lake. 
  

  

  With 
  a 
  view 
  to 
  expanding 
  fish-cultural 
  work 
  in 
  the 
  Afognak-Kodiak 
  

   region, 
  experimental 
  operations 
  were 
  undertaken 
  this 
  year 
  under 
  

   direction 
  of 
  the 
  superintendent 
  of 
  the 
  Afognak 
  station 
  at 
  Eagle 
  Lake, 
  

   which 
  is 
  a 
  few 
  miles 
  from 
  Eagle 
  Harbor 
  on 
  the 
  south 
  side 
  of 
  Kodiak 
  

   Island, 
  and 
  about 
  60 
  miles 
  from 
  Afognak. 
  A 
  barrier 
  was 
  put 
  across 
  

   the 
  river 
  a 
  short 
  distance 
  below 
  the 
  outlet 
  of 
  Eagle 
  Lake 
  hi 
  order 
  to 
  

   make 
  an 
  accurate 
  count 
  of 
  the 
  number 
  of 
  salmon 
  entering 
  its 
  waters. 
  

   As 
  a 
  result, 
  it 
  was 
  ascertained 
  that 
  from 
  July 
  1 
  to 
  August 
  12 
  a 
  total 
  

   of 
  5,416 
  sockeyes 
  and 
  1,811 
  humpback 
  salmon 
  passed 
  into 
  the 
  lake. 
  

   Temporary 
  hatching 
  troughs 
  were 
  set 
  up, 
  and 
  from 
  August 
  14 
  to 
  Sep- 
  

   tember 
  1 
  a 
  take 
  of 
  2,180,000 
  sockeye 
  eggs 
  was 
  made. 
  The 
  eggs 
  were 
  

   cared 
  for 
  until 
  well 
  eyed 
  and 
  with 
  the 
  approach 
  of 
  cold 
  weather, 
  

   which 
  necessitated 
  discontinuance 
  of 
  this 
  experimental 
  work, 
  the 
  

   eggs 
  were 
  planted 
  at 
  appropriate 
  places 
  in 
  the 
  lake. 
  

  

  During 
  the 
  course 
  of 
  the 
  season's 
  operations 
  upwards 
  of 
  5,000 
  

   Dolly 
  Varden 
  trout 
  were 
  destroyed. 
  

  

  Under 
  present 
  conditions 
  it 
  is 
  not 
  beheved 
  that 
  Eagle 
  Lake 
  offers 
  

   a 
  suitable 
  place 
  for 
  fish-cultural 
  operations. 
  The 
  water
