   immense

  The 
  same 
  is 
  true 
  of 
  the 
  Coregonus 
  fisheries 
  of 
  the 
  

   Great 
  Lakes, 
  and 
  there 
  is 
  every 
  reason 
  to 
  believe, 
  from 
  

   experiments 
  in 
  part 
  completed, 
  that 
  the 
  dominion 
  of 
  fish 
  

   culture 
  may 
  be 
  extended 
  in 
  like 
  manner 
  for 
  certain 
  of 
  the 
  

   great 
  sea 
  productions, 
  such 
  as 
  the 
  cod, 
  haddock, 
  herring, 
  

   mackerel, 
  and 
  Spanish 
  mackerel 
  fisheries. 
  

  

  The 
  immense 
  influence 
  upon 
  the 
  sea 
  fisheries 
  of 
  the 
  

   maintenance 
  of 
  the 
  abundance 
  of 
  anadromous 
  fish 
  in 
  the 
  

   rivers 
  has 
  already 
  been 
  indicated. 
  

  

  I 
  am 
  indebted 
  to 
  Mr. 
  Earll 
  for 
  the 
  following 
  statistics 
  of 
  

   the 
  work 
  of 
  the 
  United 
  States 
  Commission 
  : 
  — 
  

  

  " 
  As 
  the 
  operations 
  of 
  the 
  Commission 
  have 
  increased, 
  

   and 
  the 
  propagation 
  of 
  additional 
  species 
  has 
  been 
  

   undertaken, 
  it 
  has 
  been 
  found 
  desirable 
  to 
  increase 
  the 
  

   number 
  of 
  hatching 
  stations. 
  These 
  are 
  of 
  two 
  kinds, 
  

   known 
  as 
  collecting 
  and 
  distributing 
  stations. 
  The 
  former 
  

   are 
  located 
  near 
  the 
  spawning 
  grounds 
  of 
  those 
  species 
  

   for 
  which 
  they 
  are 
  especially 
  intended. 
  The 
  eggs 
  are 
  

   secured 
  at 
  these 
  stations, 
  and 
  enough 
  having 
  been 
  reserved 
  

   to 
  stock 
  the 
  waters 
  of 
  that 
  region, 
  the 
  remainder 
  are 
  sent 
  

   to 
  distributing 
  stations, 
  usually 
  located 
  at 
  some 
  central 
  

   point, 
  to 
  be 
  hatched 
  and 
  shipped 
  to 
  the 
  waters 
  for 
  which 
  

   they 
  are 
  intended." 
  

  

  The 
  following 
  is 
  a 
  list 
  of 
  the 
  hatching-stations 
  operated 
  

   by 
  the 
  United 
  States 
  Fish 
  Commission 
  in 
  1883
