  The 
  collection 
  of 
  black 
  -spotted 
  trout 
  eggs 
  commenced 
  at 
  Twin 
  Lakes 
  

   on 
  May 
  14 
  and 
  continned 
  nntil 
  June 
  24, 
  the 
  total 
  nnniber 
  secured 
  being 
  

   only 
  207,000. 
  The 
  results 
  were 
  very 
  discouraging, 
  as 
  oi)erations 
  had 
  

   been 
  conducted 
  not 
  only 
  with 
  the 
  Government 
  trap 
  constructed 
  the 
  

   X)revious 
  year, 
  but 
  the 
  State 
  trap 
  and 
  hatchery, 
  which 
  had 
  been 
  turned 
  

   over 
  to 
  the 
  Commission, 
  were 
  also 
  used. 
  It 
  is 
  believed 
  that 
  the 
  ])reseuce 
  

   of 
  large 
  numbers 
  of 
  suckers 
  was 
  the 
  main 
  cause 
  of 
  failure. 
  Tliey 
  

   entiered 
  Lake 
  Creek 
  in 
  such 
  numbers 
  that 
  they 
  crowded 
  each 
  other 
  partly 
  

   out 
  of 
  the 
  water, 
  and 
  each 
  morning 
  from 
  500 
  to 
  1,000 
  pounds 
  of 
  dead 
  

   ones 
  were 
  taken 
  from 
  the 
  Governmeut 
  trap, 
  and 
  a 
  ton 
  or 
  more 
  of 
  live 
  

   fish 
  were 
  turned 
  loose. 
  But 
  few 
  suckers 
  were 
  caught 
  at 
  the 
  State 
  trap, 
  

   and 
  the 
  results 
  there 
  would 
  undoubtedly 
  have 
  been 
  much 
  better, 
  but 
  

   the 
  trap 
  was 
  destroyed 
  on 
  the 
  night 
  of 
  May 
  27 
  by 
  persons 
  in 
  the 
  neigh- 
  

   borhood, 
  who 
  objected 
  to 
  its 
  being 
  operated, 
  as 
  it 
  prevented 
  the 
  trout 
  

   from 
  running 
  out 
  of 
  the 
  lower 
  lake 
  into 
  Lake 
  Creek 
  and 
  thence 
  into 
  

   the 
  Arkansas 
  Iviver. 
  

  

  At 
  the 
  time 
  the 
  trap 
  was 
  destroyed 
  000 
  native 
  trout 
  had 
  been 
  taken 
  

   and 
  the 
  siiawning 
  season 
  had 
  not 
  commenced. 
  From 
  the 
  eggs 
  obtained 
  

   25,000 
  were 
  shipped 
  to 
  the 
  Michigan 
  Fish 
  Commission; 
  the 
  balance 
  

   were 
  hatched 
  at 
  the 
  station 
  and 
  at 
  the 
  close 
  of 
  the 
  year 
  there 
  remained 
  

   on 
  hand 
  44,000. 
  The 
  large 
  loss 
  in 
  incubation 
  was 
  no 
  doubt 
  due 
  to 
  the 
  

   poor 
  quality 
  of 
  the 
  males 
  used. 
  

  

  Under 
  ordinary 
  conditions 
  the 
  eye-spots 
  appeared 
  in 
  the 
  rainbow, 
  

   yellow-finned, 
  and 
  blade-spotted 
  trout 
  eggs 
  collected 
  during 
  the 
  spring- 
  

   in 
  about 
  20 
  days, 
  and 
  the 
  eggs 
  commenced 
  hatching 
  in 
  45 
  days, 
  though 
  

   the 
  last 
  ones 
  taken 
  frequently 
  hatched 
  in 
  30 
  days 
  or 
  less, 
  according 
  to 
  

   the 
  temperature 
  of 
  the 
  water. 
  Feeding 
  commenced 
  after 
  the 
  absorption 
  

   of 
  the 
  sac, 
  which 
  required 
  from 
  20 
  to 
  30 
  days. 
  

  

  At 
  the 
  beginning 
  of 
  the 
  fiscal 
  year 
  there 
  were 
  on 
  hand 
  30,580 
  black- 
  

   spotted 
  trout 
  eggs; 
  10,000 
  of 
  these 
  were 
  shii)ped 
  to 
  the 
  Michigan 
  Com- 
  

   mission 
  and 
  arrived 
  in 
  excellent 
  condition, 
  notwithstanding 
  the 
  fact 
  

   that 
  the 
  temperature 
  was 
  over 
  100° 
  in 
  the 
  shade 
  during 
  the 
  four 
  days 
  

   the 
  consignment 
  was 
  en 
  route. 
  From 
  the 
  balance, 
  0,000 
  yearlings 
  

   were 
  reared 
  and 
  distributed 
  in 
  the 
  month 
  of 
  October 
  to 
  aj)plicants 
  in 
  

   Colorado 
  and 
  Wyoming, 
  and 
  5,000 
  were 
  deposited 
  in 
  l*>vergreen 
  and 
  

   Twin 
  Lakes.
