  REPORT 
  OF 
  COMMISSIONER 
  OF 
  FISH 
  AND 
  FISHERIES. 
  

  

  about 
  30,000,000, 
  and 
  it 
  is 
  expected 
  that 
  much 
  larger 
  results 
  will 
  be 
  

   obtained 
  hereafter. 
  

  

  An 
  equally 
  important 
  and 
  excellent 
  fish 
  is 
  the 
  white 
  perch, 
  whose 
  

   cultivation 
  has 
  now 
  become 
  desirable 
  and 
  was 
  first 
  conducted 
  on 
  a 
  

   large 
  scale 
  in 
  1903. 
  In 
  connection 
  with 
  the 
  propagation 
  of 
  shad 
  on 
  

   Susquehanna 
  River, 
  upward 
  of 
  30,000,000 
  white 
  perch 
  fry 
  were 
  

   hatched 
  and 
  planted. 
  

  

  It 
  would 
  appear 
  that 
  regular 
  operations 
  addressed 
  to 
  the 
  propaga- 
  

   tion 
  of 
  the 
  striped 
  bass 
  may 
  be 
  practicable 
  on 
  Roanoke 
  River, 
  and 
  

   that 
  large 
  numbers 
  of 
  this 
  highly 
  esteemed 
  food 
  and 
  game 
  fish 
  may 
  

   hereafter 
  be 
  produced. 
  Experimental 
  work 
  at 
  Weldon, 
  on 
  that 
  stream, 
  

   in 
  the 
  spring 
  of 
  1903, 
  resulted 
  in 
  the 
  hatching 
  of 
  upward 
  of 
  3,000,000 
  

   fry, 
  and 
  indicated 
  that 
  this 
  is 
  probably 
  the 
  best 
  site 
  on 
  the 
  coast 
  for 
  

   collecting 
  the 
  eggs 
  of 
  this 
  species, 
  which 
  up 
  to 
  this 
  time 
  has 
  received 
  

   very 
  little 
  attention 
  from 
  the 
  Commission. 
  

  

  SOME 
  RESULTS 
  OF 
  FISH 
  CULTURE. 
  

  

  During 
  the 
  year, 
  242 
  letters 
  were 
  addressed 
  to 
  applicants 
  who 
  had 
  

   received 
  fish 
  in 
  1899, 
  inquiring 
  as 
  to 
  the 
  results 
  of 
  the 
  plants. 
  Of 
  the 
  

   129 
  replies 
  received, 
  86 
  showed 
  that 
  waters 
  had 
  been 
  successfully 
  

   stocked, 
  20 
  indicated 
  failure, 
  and 
  23 
  gave 
  indefinite 
  information. 
  Inves- 
  

   tigation 
  of 
  the 
  cases 
  where 
  failure 
  occurred 
  indicated 
  that 
  the 
  waters 
  

   were 
  unsuited 
  to 
  the 
  fish 
  applied 
  for. 
  It 
  has 
  therefore 
  been 
  found 
  

   very 
  desirable 
  to 
  obtain 
  from 
  applicants 
  more 
  detailed 
  and 
  accurate 
  

   information 
  than 
  has 
  heretofore 
  been 
  asked 
  for 
  in 
  regard 
  to 
  the 
  waters 
  

   to 
  be 
  stocked, 
  and 
  new 
  blanks 
  have 
  been 
  prepared 
  with 
  this 
  in 
  view. 
  

   When 
  the 
  description 
  of 
  the 
  waters 
  to 
  be 
  stocked 
  indicates 
  that 
  the 
  

   fish 
  for 
  which 
  an 
  applicant 
  has 
  expressed 
  a 
  preference 
  is 
  well 
  suited 
  to 
  

   them, 
  it 
  is 
  customary 
  to 
  furnish 
  the 
  kind 
  desired, 
  but 
  the 
  Commission 
  

   reserves 
  the 
  right 
  to 
  determine 
  this 
  point 
  and 
  to 
  prescribe 
  the 
  proper 
  

   species. 
  

  

  From 
  correspondents 
  in 
  various 
  parts 
  of 
  the 
  country 
  who 
  have 
  vol- 
  

   unteered 
  information 
  and 
  from 
  others 
  who 
  have 
  been 
  asked 
  to 
  report 
  

   the 
  outcome 
  of 
  attempts 
  to 
  stock 
  waters 
  in 
  which 
  they 
  were 
  interested, 
  

   the 
  following 
  data, 
  showing 
  some 
  recent 
  results 
  of 
  fish 
  culture 
  and 
  fish 
  

   acclimatization, 
  have 
  been 
  obtained: 
  

  

  TROUT 
  IN 
  COLORADO, 
  SOUTH 
  DAKOTA, 
  AND 
  MONTANA. 
  

  

  Brook 
  trout, 
  rainbow 
  trout, 
  Scotch 
  lake 
  trout, 
  and 
  steelhead 
  trout 
  are 
  now 
  firmly 
  

   established 
  in 
  Colorado, 
  none 
  of 
  them 
  being 
  indigenous. 
  The 
  brook 
  trout 
  affords 
  

   better 
  fishing 
  than 
  the 
  native 
  black 
  -spotted 
  trout, 
  and 
  more 
  eggs 
  of 
  the 
  brook 
  trout 
  

   can 
  be 
  collected 
  in 
  Colorado 
  than 
  in 
  any 
  other 
  State, 
  where 
  hatcheries 
  are 
  located, 
  

   to 
  which 
  the 
  species 
  is 
  native. 
  In 
  the 
  Black 
  Hills 
  of 
  South 
  Dakota 
  and 
  adjacent 
  

   country, 
  where 
  there 
  were 
  no 
  brook 
  trout 
  twenty 
  years 
  ago, 
  all 
  of 
  the 
  before-named 
  

   trouts 
  are 
  now 
  caught. 
  Very 
  favorable 
  reports 
  have 
  also 
  come 
  from 
  Montana 
  in 
  

   regard 
  to 
  these 
  and 
  other 
  fishes 
  introduced 
  in 
  the 
  waters 
  of 
  that 
  State.
