﻿LXXXII 
  EEPORT 
  OF 
  COMMISSIONER 
  OF 
  FISH 
  AND 
  FISHERIES. 
  

  

  to 
  the 
  middle 
  of 
  April, 
  according 
  to 
  the 
  severity 
  of 
  the 
  season. 
  In 
  1878 
  

   it 
  was 
  found 
  that 
  the 
  spawning 
  season 
  in 
  the 
  Manistee 
  was 
  about 
  over 
  

   on 
  March 
  30; 
  while 
  in 
  1885 
  the 
  last 
  eggs 
  were 
  taken 
  in 
  the 
  Manistee 
  on 
  

   April 
  24, 
  and 
  in 
  the 
  An 
  Sable 
  on 
  April 
  18. 
  

  

  Several 
  attempts 
  have 
  been 
  made 
  to 
  propagate 
  the 
  grayling, 
  but 
  all 
  

   without 
  much 
  success. 
  Some 
  have 
  gone 
  so 
  far 
  as 
  to 
  hold 
  that 
  it 
  is 
  be- 
  

   yond 
  the 
  reach 
  of 
  artificial 
  fish-culture, 
  but 
  it 
  has 
  been 
  done 
  on 
  a 
  small 
  

   scale 
  with 
  a 
  slight 
  measure 
  of 
  success, 
  and 
  may 
  succeed 
  with 
  more 
  ex- 
  

   perience, 
  as 
  the 
  previous 
  work 
  has 
  been 
  largely 
  experimental. 
  In 
  the 
  

   spring 
  of 
  1876 
  there 
  were 
  handled 
  at 
  the 
  North 
  ville 
  station 
  2,000 
  eggs 
  

   taken 
  from 
  grayling 
  caught 
  by 
  Mr. 
  Fred 
  Mather, 
  and 
  a 
  small 
  percen- 
  

   tage 
  hatched; 
  and 
  in 
  April, 
  1885, 
  20,000 
  eggs 
  were 
  taken 
  from 
  fish 
  

   caught 
  with 
  hooks 
  in 
  the 
  Au 
  Sable 
  and 
  Manistee 
  Eivers, 
  and 
  the 
  hatch- 
  

   ing 
  was 
  fairly 
  successful, 
  but 
  heavy 
  mortality 
  occurred 
  after 
  hatching, 
  

   as 
  no 
  suitable 
  food 
  was 
  found 
  for 
  the 
  young 
  fish. 
  Those 
  that 
  lived, 
  

   however, 
  did 
  well 
  and 
  grew 
  rapidly. 
  The 
  Michigan 
  State 
  Fish 
  Com- 
  

   mission 
  has 
  made 
  several 
  experiments 
  in 
  cultivating 
  this 
  fish, 
  but 
  all 
  

   without 
  definite 
  result. 
  Experience 
  seems 
  to 
  show 
  very 
  clearly 
  that 
  

   the 
  grayling 
  will 
  not 
  successfully 
  endure 
  domestication 
  or 
  confinement 
  

   in 
  trout 
  ponds, 
  as 
  in 
  1884 
  the 
  Michigan 
  Commission 
  placed 
  a 
  number 
  of 
  

   adult 
  grayling 
  in 
  its 
  trout 
  ponds 
  at 
  Paris, 
  Mich., 
  but 
  not 
  a 
  fish 
  has 
  

   spawned 
  or 
  showed 
  the 
  slightest 
  inclination 
  to 
  do 
  so, 
  while 
  they 
  have 
  

   gradually 
  died, 
  till 
  but 
  few 
  are 
  left. 
  Experiments 
  in 
  this 
  line 
  will 
  prob- 
  

   ably 
  be 
  continued 
  under 
  more 
  favorable 
  and 
  natural 
  conditions. 
  Credit 
  

   is 
  due 
  to 
  Mr. 
  Martin 
  Metcalf 
  for 
  first 
  obtaining 
  the 
  eggs 
  artificially 
  from 
  

   grayling 
  reared 
  in 
  the 
  ponds 
  of 
  the 
  Michigan 
  Fish 
  Commission, 
  and 
  

   for 
  impregnating 
  and 
  hatching 
  the 
  same. 
  This 
  was 
  done 
  in 
  the 
  winter 
  

   of 
  1879-'80. 
  

  

  The 
  Wytheville 
  Station. 
  — 
  In 
  the 
  spring 
  of 
  1885 
  about 
  300 
  grayling 
  were 
  

   hatched 
  from 
  eggs 
  collected 
  from 
  wild 
  fish 
  in 
  the 
  streams 
  of 
  Michigan 
  

   by 
  Mr. 
  F. 
  N. 
  Clark 
  and 
  forwarded 
  to 
  Wytheville. 
  These 
  300 
  fish 
  are 
  

   being 
  kept 
  for 
  breeders, 
  and 
  at 
  the 
  close 
  of 
  the 
  year 
  were 
  in 
  fine 
  condi- 
  

   tion.

  The 
  Northville 
  Station. 
  — 
  The 
  work 
  of 
  the 
  past 
  season 
  may 
  be 
  regarded 
  

   as 
  fairly 
  successful, 
  though 
  not 
  so 
  much 
  was 
  done 
  as 
  usual. 
  In 
  all, 
  

   225,000 
  eggs 
  were 
  obtained 
  ; 
  from 
  which 
  number, 
  145,000 
  eggs 
  were 
  

   shipped, 
  25,000 
  fry 
  hatched, 
  and 
  25,000 
  eggs 
  sent 
  to 
  the 
  Michigan 
  fish 
  

   commission 
  at 
  Paris, 
  Mich., 
  in 
  exchange 
  for 
  an 
  equal 
  number 
  of 
  eggs 
  

   of 
  the 
  same 
  species 
  which 
  were 
  hatched 
  at 
  Northville 
  and 
  mostly 
  re- 
  

   tained 
  for 
  breeding 
  purposes. 
  Of 
  the 
  145,000 
  eggs 
  shipped, 
  30,000 
  

   went 
  to 
  Mr. 
  Fred 
  Mather, 
  25,000 
  of 
  which 
  were 
  reshipped 
  to 
  the 
  Deutsche 
  

   Fischerei- 
  Verein 
  of 
  Germany, 
  10,000 
  to 
  the 
  National 
  Fish 
  Culture

   ciation 
  of 
  England, 
  and 
  1,000 
  to 
  the 
  Government 
  of 
  Switzerland, 
  the 
  

   rest 
  being 
  distributed 
  among 
  State 
  commissioners 
  and
