  REPORT 
  OF 
  COMMISSIONER 
  OF 
  FISH 
  AND 
  FISHERIES. 
  [4] 
  

  

  at 
  Alpena 
  Hatchery, 
  a 
  satisfactory 
  increase 
  over 
  the 
  work 
  of 
  last 
  season. 
  

   The 
  eggs 
  shipped 
  to 
  North 
  ville 
  were 
  taken 
  principally 
  from 
  the 
  island 
  

   region 
  of 
  western 
  Lake 
  Erie, 
  and 
  at 
  Monroe, 
  Mich., 
  from 
  penned 
  fish. 
  

   Later 
  in 
  the 
  season, 
  however, 
  16,000,000 
  of 
  the 
  eggs 
  taken 
  in 
  at 
  Alpena 
  

   were 
  repacked 
  and 
  shipped 
  to 
  Northville, 
  as 
  better 
  facilities 
  for 
  ship- 
  

   ping 
  are 
  obtainable 
  at 
  the 
  latter 
  place. 
  The 
  first 
  eggs 
  were 
  received 
  from 
  

   the 
  spawning 
  beds 
  of 
  Lake 
  Erie 
  on 
  November 
  11, 
  and 
  the 
  last 
  on 
  Decem- 
  

   ber 
  7. 
  The 
  general 
  plan 
  of 
  operations 
  in 
  the 
  manipulation 
  of 
  spawn 
  and 
  

   the 
  treatment 
  of 
  fry 
  varies 
  so 
  little 
  from 
  preceding 
  years 
  that 
  it 
  is 
  unnec- 
  

   essary 
  to 
  dwell 
  at 
  length 
  upon 
  this 
  department 
  of 
  the 
  industry. 
  Eggs 
  

   commenced 
  hatching 
  at 
  Northville 
  on 
  March 
  7 
  and 
  ended 
  on 
  April 
  20, 
  

   thus 
  showing 
  an 
  average 
  period 
  of 
  incubation 
  of 
  one 
  hundred 
  and 
  twenty- 
  

   five 
  days. 
  The 
  temperature 
  of 
  water 
  varied 
  from 
  32° 
  to 
  43° 
  Fahr., 
  aver- 
  

   aging 
  34^°. 
  The 
  water 
  used 
  for 
  whitefish 
  eggs 
  at 
  North 
  ville 
  was 
  pumped 
  

   from 
  a 
  small 
  river 
  near 
  the 
  hatchery 
  ; 
  that 
  used 
  at 
  Alpena 
  was 
  drawn 
  from 
  

   Thunder 
  Bay. 
  The 
  hatching 
  season 
  at 
  Alpena 
  was 
  about 
  a 
  month 
  later 
  

   than 
  at 
  Northville. 
  The 
  period 
  of 
  spawning 
  in 
  the 
  waters 
  of 
  Lakes 
  

   Huron 
  and 
  Michigan 
  varies 
  considerably 
  from 
  that 
  of 
  Erie, 
  but 
  the 
  

   great 
  bulk 
  of 
  eggs 
  are 
  taken 
  at 
  the 
  same 
  time, 
  consequently 
  the 
  busy 
  

   season 
  at 
  Alpena 
  commences 
  about 
  the 
  same 
  time 
  as 
  at 
  North 
  vilie. 
  

   There 
  are 
  several 
  localities 
  in 
  the 
  waters 
  of 
  Lakes 
  Huron 
  and 
  Michigan 
  

   where 
  eggs 
  are 
  taken 
  for 
  Alpena 
  Station, 
  but 
  at 
  least 
  75 
  per 
  cent 
  are 
  

   and 
  obtained 
  at 
  Miller's 
  Point 
  and 
  Alcona, 
  in 
  Lake 
  Huron, 
  and 
  Epoufette 
  

   and 
  Thompson, 
  in 
  Lake 
  Michigan. 
  

  

  The 
  season's 
  shipments 
  of 
  eggs 
  were 
  made 
  principally 
  during 
  the 
  

   months 
  of 
  December 
  and 
  January, 
  as 
  shown 
  in 
  the 
  following 
  tables, 
  to 
  

   several 
  States 
  and 
  Territories, 
  the 
  District 
  of 
  Columbia, 
  England, 
  Ger- 
  

   many, 
  Switzerland, 
  and 
  New 
  Zealand 
  by 
  way 
  of 
  California, 
  this 
  last 
  cov- 
  

   ering 
  a 
  distance 
  of 
  nearly 
  half 
  around 
  the 
  globe. 
  

  

  BROOK 
  TROUT. 
  

  

  The 
  brook-trout 
  work 
  this 
  season 
  may 
  be 
  considered 
  fairly 
  successful, 
  

   although 
  it 
  would 
  scarcely 
  be 
  a 
  favorable 
  comparison 
  with 
  that 
  of 
  the 
  

   past 
  few 
  seasons. 
  In 
  all, 
  225,000 
  eggs 
  were 
  obtained 
  ; 
  from 
  which 
  num- 
  

   ber, 
  145,000 
  eggs 
  were 
  shipped, 
  and 
  25,000 
  fry 
  hatched, 
  4,000 
  of 
  which 
  

   were 
  shipped 
  during 
  April 
  and 
  May, 
  as 
  follows 
  :

  The 
  remaining 
  fry 
  have 
  been 
  kept 
  to 
  replenish 
  ponds 
  from 
  which 
  

   yearlings 
  and 
  two-year-olds 
  have 
  been 
  distributed. 
  The 
  first 
  eggs 
  were 
  

   taken 
  from 
  a 
  two-year-old 
  on 
  October 
  16. 
  The 
  fish 
  continued 
  to 
  spawn 
  

   till 
  December 
  31, 
  on 
  which 
  date 
  400 
  eggs 
  were 
  taken 
  from 
  a 
  two-year- 
  

   old, 
  which 
  closed 
  the 
  spawning 
  season.
