  OF

  In 
  Lake 
  Ontario 
  the 
  newly 
  developed 
  fields 
  for 
  the 
  collection 
  of 
  

   eggs 
  of 
  the 
  whitefish, 
  cisco, 
  lake 
  trout, 
  and 
  pike 
  perch 
  were 
  operated 
  

   during 
  the 
  respective 
  spawning 
  seasons. 
  Three-Mile 
  Bay 
  and 
  waters 
  

   in 
  the 
  immediate 
  vicinity 
  of 
  the 
  Cape 
  Vincent 
  station 
  yielded 
  1 
  ,160,000 
  

   whitefish 
  and 
  5,350,000 
  cisco 
  eggs; 
  144,160 
  lake-trout 
  eggs 
  were 
  

   secured 
  from 
  the 
  Pigeon 
  Island 
  fishery, 
  while 
  3,937,500 
  pike-perch 
  

   eggs 
  of 
  fair 
  quality 
  were 
  obtained 
  in 
  Mud 
  Creek. 
  Far 
  more 
  satis- 
  

   factory 
  results 
  might 
  have 
  been 
  accomplished 
  m 
  all 
  these 
  fields 
  had 
  

   not 
  the 
  work 
  been 
  hampered 
  during 
  the 
  entire 
  period 
  of 
  operations 
  

   by 
  the 
  unfavorable 
  weather 
  and 
  water 
  conditions 
  prevailing. 
  These 
  

   eggs, 
  together 
  with 
  40,750,000 
  eggs 
  of 
  whitefish, 
  lake 
  trout, 
  and 
  pike 
  

   perch 
  transferred 
  from 
  other 
  stations, 
  were 
  successfully 
  hatched 
  and 
  

   distributed, 
  most 
  of 
  the 
  fry 
  being 
  liberated 
  in 
  Lake 
  Ontario. 
  

  

  The 
  collections 
  of 
  pike-perch 
  eggs 
  for 
  the 
  Swanton, 
  Vt., 
  station 
  were 
  

   only 
  about 
  half 
  as 
  large 
  as 
  those 
  of 
  the 
  preceding 
  year, 
  the 
  com- 
  

   parative 
  failure 
  being 
  partially 
  due 
  to 
  the 
  scarcity 
  of 
  female 
  fish 
  on 
  

   the 
  spawning 
  grounds. 
  Male 
  fish 
  were 
  there 
  in 
  great 
  abundance, 
  

   and 
  later 
  in 
  the 
  season 
  a 
  consignment 
  of 
  green 
  females 
  was 
  tranferred 
  

   from 
  the 
  Canadian 
  fishing 
  grounds 
  in 
  the 
  north 
  end 
  of 
  Missisquoi 
  

   Bay 
  and 
  placed 
  in 
  a 
  rude 
  inclosure 
  which 
  had 
  been 
  provided 
  for 
  them 
  

   m 
  Lake 
  Champlain, 
  in 
  the 
  vicinity 
  of 
  the 
  field 
  of 
  operations. 
  They 
  were 
  

   held 
  in 
  good 
  condition 
  so 
  long 
  as 
  a 
  sufficient 
  depth 
  of 
  water 
  could 
  be 
  

   maintained 
  in 
  the 
  inclosure, 
  but 
  before 
  their 
  eggs 
  had 
  matured 
  in 
  con- 
  

   siderable 
  numbers 
  the 
  water 
  in 
  the 
  lake 
  receded 
  and 
  became 
  so 
  warm 
  

   that, 
  m 
  order 
  to 
  prevent 
  the 
  total 
  loss 
  of 
  the 
  impounded 
  fish, 
  the 
  bulk 
  

   of 
  thsm 
  were 
  liberated 
  before 
  they 
  had 
  ripened. 
  

  

  With 
  the 
  view 
  of 
  being 
  nearer 
  the 
  fishing 
  grounds, 
  and 
  also 
  in 
  order 
  

   that 
  the 
  Bureau 
  might 
  conduct 
  its 
  operations 
  independently 
  of 
  the 
  

   various 
  persons 
  controlling 
  the 
  river 
  shores 
  heretofore 
  occupied, 
  stepg 
  

   were 
  taken 
  in 
  advance 
  of 
  the 
  spawning 
  season 
  to 
  establish 
  a 
  collecting 
  

   and 
  penning 
  station 
  on 
  Lake 
  Champlain, 
  at 
  Sandy 
  Pomt, 
  and 
  while 
  

   the 
  outcome 
  of 
  the 
  operations 
  was 
  not 
  as 
  favorable 
  as 
  had 
  been 
  antici- 
  

   pated 
  it 
  is 
  believed 
  the 
  change 
  in 
  location 
  prevented 
  what 
  would 
  have 
  

   otherwise 
  been 
  an 
  almost 
  complete 
  failure, 
  and 
  that 
  the 
  difficulties 
  

   encountered 
  this 
  season 
  may 
  be 
  largely 
  overcome 
  another 
  year 
  by 
  

   providmg 
  more 
  suitable 
  impounding 
  facilities. 
  The 
  collections 
  num- 
  

   bered 
  111,037,500, 
  and 
  the 
  output 
  of 
  fry 
  was 
  58,280,000. 
  In 
  con- 
  

   nection 
  with 
  the 
  pike-perch 
  work, 
  23,300,000 
  eggs 
  of 
  the 
  yellow 
  perch 
  

   were 
  secured, 
  11,000,000 
  of 
  which 
  were 
  utilized 
  in 
  filling 
  applications 
  

   from 
  State 
  fish 
  commissions. 
  The 
  remainder 
  were 
  hatched 
  and 
  the 
  

   fry 
  returned 
  to 
  the 
  spawning 
  grounds. 
  

  

  Reports 
  as 
  to 
  the 
  abundance 
  of 
  the 
  Lake 
  Champlain 
  whitefish 
  in 
  

   the 
  vicinity 
  of 
  the 
  Swanton 
  station 
  having 
  led 
  to 
  the 
  belief 
  that 
  there 
  

   was 
  a 
  possibility 
  of 
  satisfactory 
  results 
  in 
  the 
  artificial 
  propagation
