  COMMISSIONER 
  OF 
  FISH 
  AND 
  FISHERIES. 
  

  

  exercise 
  of 
  great 
  care 
  in 
  the 
  transportation 
  of 
  the 
  eggs 
  over 
  the 
  rough 
  

   mountain 
  roads 
  from 
  the 
  lake 
  to 
  the 
  railroad 
  station. 
  Only 
  13 
  per 
  cent 
  

   of 
  the 
  493,700 
  taken 
  were 
  lost. 
  At 
  Decker 
  Lake 
  511,500 
  eggs 
  were 
  

   taken, 
  but, 
  owing 
  to 
  the 
  fact 
  that 
  the 
  fish 
  were 
  very 
  closely 
  confined 
  in 
  

   retaining 
  vats 
  during 
  extremely 
  cold 
  weather, 
  55 
  x)er 
  cent 
  of 
  the 
  eggs 
  

   and 
  20 
  per 
  cent 
  of 
  the 
  fry 
  were 
  lost. 
  At 
  the 
  time 
  the 
  last 
  lot 
  of 
  eggs 
  

   were 
  taken 
  the 
  thermometer 
  registered 
  20^ 
  below 
  zero 
  in 
  the 
  cabin 
  where 
  

   operations 
  were 
  being 
  conducted; 
  the 
  eggs 
  froze 
  to 
  the 
  pans 
  and 
  the 
  

   fish 
  died 
  within 
  a 
  few 
  minntes 
  after 
  being 
  handled. 
  The 
  eggs 
  taken 
  at 
  

   Young 
  Lake 
  yielded 
  57,615 
  fry, 
  or 
  SO 
  per 
  cent 
  of 
  the 
  number 
  collected. 
  

  

  During 
  the 
  winter 
  190,000 
  trout 
  eggs 
  were 
  shipped 
  to 
  the 
  various 
  

   State 
  fish 
  commissions, 
  private 
  individuals, 
  and 
  stations 
  of 
  the 
  United 
  

   States 
  Commission. 
  The 
  balance 
  were 
  hatched, 
  and 
  on 
  May 
  1 
  there 
  

   were 
  at 
  the 
  station 
  1,021,200 
  fry, 
  479,000 
  of 
  which 
  belonged 
  to 
  private 
  

   parties. 
  Owing 
  to 
  very 
  cold 
  weather 
  throughout 
  the 
  spring, 
  they 
  did 
  

   not 
  commence 
  taking 
  food 
  until 
  they 
  were 
  about 
  80 
  days 
  old. 
  

  

  In 
  order 
  to 
  make 
  room 
  for 
  the 
  eggs 
  of 
  the 
  rainbow, 
  black-spotted, 
  and 
  

   yellow-finned 
  trout, 
  287,000 
  of 
  the 
  fish 
  belonging 
  to 
  the 
  Commission 
  

   were 
  distributed 
  in 
  Maj^ 
  and 
  June 
  to 
  applicants 
  in 
  Colorado. 
  The 
  losses 
  

   during 
  this 
  period 
  amounted 
  to 
  less 
  than 
  2^ 
  per 
  cent, 
  and 
  at 
  the 
  close 
  

   of 
  the 
  year 
  there 
  were 
  241,465 
  on 
  hand. 
  

  

  Bainhoic 
  trout. 
  — 
  The 
  stock 
  on 
  hand 
  at 
  the 
  beginning 
  of 
  the 
  year 
  was 
  

   derived 
  from 
  collections 
  made 
  at 
  Twin 
  and 
  Uneva 
  lakes 
  during 
  the 
  

   previous 
  spring, 
  and 
  in 
  September, 
  when 
  the 
  fish 
  were 
  distributed, 
  the 
  

   output 
  amounted 
  to 
  25,500. 
  In 
  February 
  a 
  consignment 
  of 
  44,000 
  eggs 
  

   was 
  received 
  from 
  Neosho. 
  The 
  loss 
  during 
  incubation 
  was 
  only 
  10 
  per 
  

   cent, 
  but 
  the 
  fry 
  were 
  very 
  weak 
  and 
  such 
  large 
  numbers 
  of 
  them 
  died 
  

   during 
  the 
  sac 
  stage 
  that 
  there 
  were 
  only 
  2,000 
  available 
  for 
  distribu- 
  

   tion 
  in 
  the 
  spring. 
  Collections 
  of 
  eggs 
  were 
  again 
  made 
  at 
  Twin 
  and 
  

   Uneva 
  lakes 
  in 
  May 
  and 
  June, 
  54,000 
  being 
  secured 
  from 
  both 
  sources. 
  

   The 
  spawning 
  season 
  opened 
  on 
  May 
  10, 
  and 
  the 
  eggs 
  commenced 
  

   hatching 
  in 
  27 
  days, 
  the 
  eye-spots 
  appearing 
  in 
  13 
  days. 
  The 
  losses 
  

   during 
  incubation 
  amounted 
  to 
  27 
  per 
  cent, 
  and 
  at 
  the 
  close 
  of 
  the 
  year 
  

   there 
  were 
  25,370 
  fish 
  and 
  8,000 
  eggs 
  on 
  hand. 
  

  

  Yelloiv-Jinried 
  trout. 
  — 
  When 
  the 
  general 
  distribution 
  was 
  made 
  in 
  Sep- 
  

   tember 
  the 
  output 
  of 
  the 
  species 
  amounted 
  to 
  7,931. 
  Collections 
  of 
  

   eggs 
  were 
  made 
  during 
  the 
  following 
  May 
  at 
  Twin 
  Lakes, 
  and 
  as 
  a 
  

   result 
  there 
  were 
  8,480 
  fry 
  on 
  hand 
  at 
  the 
  close 
  of 
  the 
  year. 
  The 
  losses 
  

   during 
  incubation 
  amounted 
  to 
  3,920. 
  

  

  Blade-spotted 
  trout. 
  — 
  The 
  use 
  of 
  the 
  State 
  trap 
  and 
  hatchery 
  at 
  Twin 
  

   Lakes 
  having 
  been 
  tendered 
  the 
  Commission 
  by 
  the 
  State 
  authorities, 
  

   arrangements 
  were 
  made 
  to 
  conduct 
  operations 
  there 
  on 
  a 
  larger 
  scale 
  

   than 
  heretofore, 
  but 
  as 
  it 
  was 
  necessary 
  to 
  keep 
  a 
  man 
  on 
  watch 
  con- 
  

   stantly 
  to 
  prevent 
  the 
  theft 
  of 
  the 
  fish 
  and 
  the 
  destruction 
  of 
  the 
  trap, 
  

   the 
  results 
  were 
  not 
  commensurate 
  with 
  the 
  expense 
  involved, 
  though 
  

   they 
  were 
  better 
  than 
  in 
  previous 
  years. 
  A 
  collection 
  of 
  167,000 
  eggs 
  

   was 
  made 
  at 
  Freeman 
  Lake 
  in 
  June, 
  and 
  5,200 
  were 
  secured 
  from 
  the
