  REPORT 
  OF 
  COMMISSIONER 
  OF 
  FISH 
  AND 
  FISHERIES. 
  

  

  that 
  the 
  eggs 
  from 
  the 
  second 
  year's 
  stripping 
  are 
  preferable 
  to 
  those 
  

   of 
  younger 
  fish. 
  For 
  a 
  comparison 
  of 
  methods, 
  during 
  the 
  past 
  year 
  

   the 
  eggs 
  from 
  six 
  private 
  hatcheries 
  were 
  placed 
  side 
  by 
  side 
  in 
  

   troughs 
  at 
  the 
  various 
  stations 
  and 
  incubated 
  under 
  similar 
  conditions 
  

   of 
  water 
  supply. 
  It 
  was 
  found 
  that 
  there 
  is 
  a 
  great 
  difference 
  in 
  the 
  

   quality 
  of 
  eggs 
  received 
  from 
  different 
  hatcheries, 
  undoubtedl}' 
  due 
  

   to 
  the 
  condition 
  of 
  the 
  parent 
  fish, 
  which 
  at 
  some 
  stations 
  may 
  be 
  

   crowded 
  and 
  overfed. 
  Where 
  extensive 
  purchases 
  of 
  eggs 
  are 
  made 
  

   the 
  cost 
  of 
  transportation 
  is 
  an 
  item 
  for 
  consideration, 
  and 
  in 
  this 
  

   connection 
  it 
  is 
  noted 
  that 
  the 
  nature 
  of 
  the 
  material 
  in 
  which 
  the 
  eggs 
  

   are 
  packed 
  has 
  much 
  to 
  do 
  with 
  the 
  cost 
  of 
  transportation. 
  Where 
  

   dried 
  forest 
  leaves 
  are 
  used 
  the 
  cost 
  of 
  shipment 
  is 
  about 
  one-half 
  the 
  

   cost 
  when 
  sawdust 
  is 
  used. 
  Dried 
  leaves 
  are 
  the 
  most 
  desirable 
  

   packing, 
  but 
  of 
  the 
  other 
  materials 
  used 
  dried 
  moss 
  or 
  shavings 
  are 
  

   preferable 
  to 
  sawdust. 
  

  

  As 
  a 
  result 
  of 
  special 
  efforts 
  to 
  extend 
  the 
  work 
  of 
  propagating 
  the 
  

   Atlantic 
  salmon, 
  the 
  output 
  was 
  nearly 
  three 
  times 
  as 
  great 
  as 
  in 
  the 
  

   previous 
  year, 
  and 
  a 
  larger 
  number 
  than 
  usual 
  was 
  reared 
  as 
  finger- 
  

   lings 
  and 
  yearlings. 
  

  

  The 
  shad 
  season 
  was 
  fairly 
  successful, 
  and 
  156,873,000 
  eggs 
  were 
  

   secured. 
  Early 
  in 
  March 
  the 
  weather 
  was 
  unusually 
  warm, 
  causing 
  

   the 
  water 
  temperature 
  to 
  rise, 
  and 
  attracting 
  the 
  shad 
  to 
  the 
  rivers. 
  At 
  

   the 
  Eden 
  ton, 
  N. 
  C. 
  , 
  station, 
  about 
  the 
  average 
  collections 
  were 
  obtained, 
  

   but 
  at 
  the 
  station 
  on 
  the 
  Potomac 
  River 
  the 
  take 
  of 
  eggs 
  was 
  larger 
  

   than 
  ever 
  before. 
  A 
  cold 
  wave 
  in 
  April 
  greatly 
  retarded 
  and 
  inter- 
  

   fered 
  with 
  operations 
  on 
  the 
  Susquehanna 
  and 
  Delaware 
  rivers, 
  and 
  the 
  

   results 
  at 
  those 
  stations 
  were 
  much 
  less 
  than 
  had 
  been 
  anticipated. 
  

  

  The 
  collection 
  of 
  lake 
  trout 
  eggs 
  at 
  the 
  Great 
  Lakes 
  stations 
  was 
  the 
  

   largest 
  in 
  the 
  history 
  of 
  the 
  Commission, 
  the 
  results 
  being 
  especially 
  

   good 
  on 
  Lake 
  Michigan, 
  where 
  a 
  new 
  station 
  was 
  established 
  at 
  Charle- 
  

   voix. 
  The 
  egg 
  collections 
  amounted 
  to 
  51,841,000, 
  most 
  of 
  the 
  eggs 
  

   being 
  taken 
  during 
  the 
  closed 
  season 
  b}'^ 
  means 
  of 
  tugs 
  hired 
  to 
  secure 
  

   the 
  ripe 
  fish, 
  and 
  the 
  fry 
  hatched 
  from 
  them 
  were 
  planted 
  on 
  the 
  

   spawning 
  grounds. 
  Preparations 
  were 
  made 
  for 
  penning 
  white-fish 
  

   on 
  an 
  extended 
  scale, 
  but 
  owing 
  to 
  warm 
  weather 
  during 
  the 
  spawning 
  

   season 
  the 
  collections 
  fell 
  somewhat 
  behind 
  those 
  of 
  the 
  previous 
  year. 
  

   The 
  total 
  number 
  of 
  eggs 
  taken 
  was 
  409,384,000, 
  secured 
  from 
  the 
  

   penned 
  fish 
  and 
  from 
  commercial 
  fishermen 
  operating 
  in 
  the 
  various 
  

   fields 
  on 
  Lake 
  Erie 
  and 
  the 
  Detroit 
  River. 
  Of 
  these 
  the 
  state 
  fish 
  

   commissions 
  were 
  given 
  63,052,000; 
  the 
  remainder 
  were 
  hatched 
  and 
  

   the 
  fry 
  liberated 
  in 
  the 
  waters 
  from 
  which 
  the 
  parent 
  fish 
  were 
  

   obtained. 
  

  

  As 
  in 
  the 
  past, 
  the 
  principal 
  work 
  of 
  the 
  Commission 
  on 
  the 
  Pacific 
  

   coast 
  during 
  the 
  year 
  has 
  been 
  the 
  propagation 
  of 
  the 
  quinnat 
  salmon, 
  

   operations 
  being 
  conducted 
  at 
  11 
  stations 
  located 
  in 
  California, 
  Oregon,
