  of 
  the 
  year 
  there 
  remained 
  on 
  hand 
  131,141 
  landlocked 
  salmon, 
  16,220 
  

   Atlantic 
  salmon, 
  and 
  9,335 
  steelliead 
  trout. 
  

  

  Having" 
  decided 
  to 
  discontinue 
  tlie 
  distribution 
  of 
  Von 
  Behr 
  trout, 
  

   the 
  709 
  brood 
  fish 
  on 
  hand 
  in 
  the 
  fall 
  were 
  turned 
  over 
  to 
  the 
  fish 
  com- 
  

   missions 
  of 
  Maine 
  and 
  Vermont. 
  While 
  the 
  flume 
  was 
  being 
  prepared 
  

   during 
  the 
  summer 
  it 
  was 
  found 
  impracticable 
  to 
  provide 
  ponds 
  for 
  the 
  

   landlocked 
  salmon 
  that 
  had 
  been 
  reared 
  at 
  the 
  station, 
  and, 
  in 
  view 
  of 
  

   the 
  fact 
  that 
  they 
  were 
  about 
  G 
  years 
  old 
  and 
  had 
  never 
  produced 
  

   healthy 
  eggs, 
  it 
  was 
  determined 
  to. 
  liberate 
  them 
  in 
  Green 
  Lake. 
  Jhere 
  

   were 
  2,104 
  of 
  these 
  fish, 
  varying 
  from 
  1 
  to 
  3 
  pounds 
  when 
  liberated. 
  

  

  Craig 
  Brook 
  .Station, 
  Maine 
  (Charles 
  G. 
  Atkins, 
  Superintendent). 
  

  

  During 
  the 
  year 
  two 
  large, 
  deep 
  ponds 
  were 
  constructed 
  on 
  the 
  flat 
  

   alongside 
  Alamoosook 
  Lake 
  for 
  the 
  jjurpose 
  of 
  continuing 
  the 
  experi- 
  

   ment 
  of 
  rearing 
  Atlantic 
  salmon 
  under 
  domestication 
  and 
  for 
  domesti- 
  

   cating 
  such 
  species 
  as 
  the 
  steelhead 
  trout, 
  landlocked 
  salmon, 
  and 
  

   quinnat 
  salmon. 
  These 
  i)onds 
  are 
  each 
  about 
  3,750 
  feet 
  in 
  area, 
  and 
  

   the 
  expense 
  of 
  building 
  them 
  was 
  $679. 
  In 
  addition 
  to 
  a 
  number 
  of 
  

   minor 
  improvements 
  to 
  the 
  buildings 
  and 
  grounds, 
  the 
  old 
  wagon-house 
  

   was 
  moved 
  and 
  repaired, 
  a 
  stone 
  bridge 
  was 
  built 
  across 
  the 
  brook, 
  two 
  

   gravel 
  breakwaters 
  were 
  constructed 
  to 
  protect 
  the 
  boat-landing, 
  the 
  

   fly-house 
  was 
  transformed 
  into 
  a 
  hatchery 
  for 
  the 
  purpose 
  of 
  caring 
  for 
  

   the 
  quinnat-salmon 
  eggs 
  transferred 
  from 
  the 
  Pacific 
  Coast, 
  and 
  a 
  new 
  

   stand 
  of 
  troughs 
  was 
  erected 
  for 
  holding 
  the 
  fry. 
  An 
  aqueduct 
  700 
  

   feet 
  long 
  was 
  also 
  constructed 
  in 
  order 
  to 
  convey 
  the 
  water 
  supi)ly 
  from 
  

   Craig 
  Brook 
  to 
  the 
  above-mentioned 
  stands 
  and 
  hatchery. 
  

  

  At 
  the 
  beginning 
  of 
  the 
  year 
  there 
  were 
  on 
  hand 
  the 
  following 
  fry, 
  

   hatched 
  the 
  previous 
  spring:

  Total

  During 
  July 
  3,315 
  steelheads 
  were 
  liberated: 
  the 
  remainder 
  of 
  the 
  

   stock 
  was 
  carried 
  through 
  to 
  October, 
  when 
  the 
  fish 
  were 
  counted 
  and 
  

   distributed 
  with 
  comparatively 
  small 
  losses 
  The 
  food 
  given 
  was 
  the 
  

   same 
  material 
  usually 
  employed 
  — 
  chopped 
  liver 
  and 
  other 
  butchers' 
  

   offal, 
  the 
  flesh 
  of 
  horses, 
  and 
  maggots 
  reared 
  at 
  the 
  station. 
  A 
  small 
  

   quantity 
  of 
  herring 
  roe 
  was 
  also 
  used 
  and 
  appeared 
  to 
  be 
  acceptable 
  

   to 
  the 
  quinnats, 
  though 
  it 
  was 
  not 
  readily 
  taken 
  by 
  the 
  Atlantic 
  salmon. 
  

   As 
  in 
  former 
  years 
  the 
  food 
  most 
  readily 
  eaten 
  was 
  the 
  maggots, 
  which 
  

   were 
  given 
  alive. 
  This 
  year 
  for 
  the 
  first 
  time 
  a 
  large 
  number 
  of 
  fry 
  

   were 
  kept 
  in 
  tbe 
  ponds, 
  and 
  although 
  the 
  losses 
  were 
  slightly 
  heavier 
  

   than 
  heretofore, 
  these 
  fry 
  did 
  remarkably 
  well 
  and 
  outgrew 
  the 
  trough 
  

   fish. 
  In 
  all, 
  102,205 
  Atlantic 
  salmon 
  and 
  8,122 
  steelhead 
  trout 
  were 
  

   transferred 
  to 
  the 
  ponds; 
  three 
  months 
  later 
  91,017 
  Atlantic 
  salmon 
  

   and 
  7,398 
  steelheads 
  were 
  removed, 
  showing 
  a 
  loss 
  of 
  11 
  per 
  cent 
  on 
  the
