  Rainbow

  — 
  The 
  brood 
  stock 
  at 
  the 
  station 
  in 
  November 
  con- 
  

   sisted 
  of 
  1,G23 
  lish 
  from 
  4 
  to 
  8 
  years 
  old, 
  700 
  three-year 
  olds, 
  515 
  two- 
  

   year 
  olds, 
  and 
  1,200 
  yearlings. 
  The 
  spawning 
  season 
  commenced 
  on 
  

   November 
  6 
  and 
  contiuued 
  until 
  February 
  5, 
  during 
  which 
  time 
  770,440 
  

   eggs 
  were 
  collected 
  from 
  984 
  iish, 
  620 
  males 
  being 
  used 
  to 
  fertilize 
  them. 
  

   Of 
  these 
  eggs 
  245,000 
  were 
  assigned 
  to 
  State 
  fish 
  commissions, 
  foreign 
  

   societies, 
  and 
  private 
  applicants; 
  52,000 
  were 
  transferred 
  to 
  other 
  sta- 
  

   tions 
  of 
  the 
  Commission; 
  and 
  from 
  the 
  balance 
  365,000 
  healthy 
  fry 
  were 
  

   hatched. 
  During 
  March 
  and 
  April 
  120,000 
  of 
  these 
  were 
  distributed 
  

   to 
  applicants 
  in 
  Virginia 
  and 
  Tennessee; 
  the 
  remainder 
  were 
  placed 
  in 
  

   troughs 
  in 
  the 
  hatchery 
  and 
  in 
  outside 
  ponds 
  to 
  be 
  reared 
  for 
  the 
  fall 
  

   distribution, 
  the 
  losses 
  to 
  the 
  close 
  of 
  the 
  fiscal 
  year 
  amounting 
  to 
  

   63,038. 
  

  

  During 
  the 
  early 
  stages 
  of 
  the 
  existence 
  of 
  the 
  fry 
  their 
  diet 
  consisted 
  

   entirely 
  of 
  canned 
  herring 
  roe 
  and 
  salted 
  cod 
  roe, 
  but 
  from 
  May 
  1 
  to 
  

   the 
  close 
  of 
  the 
  year 
  a 
  mixture 
  of 
  liver 
  and 
  mush 
  was 
  given 
  to 
  them. 
  

   After 
  an 
  experience 
  of 
  two 
  years, 
  fish 
  roe, 
  either 
  salted 
  or 
  canned, 
  is 
  

   considered 
  far 
  superior 
  to 
  the 
  usual 
  liver 
  diet 
  for 
  small 
  fry. 
  Of 
  the 
  two 
  

   preparations 
  the 
  canned 
  roe 
  is 
  preferable. 
  

  

  There 
  were 
  no 
  unusual 
  casualties 
  until 
  June 
  23, 
  when 
  the 
  water 
  

   supply 
  to 
  one 
  of 
  the 
  ponds 
  was 
  obstructed 
  for 
  several 
  hours, 
  resulting 
  

   in 
  the 
  loss 
  of 
  327 
  two-year 
  old 
  fish. 
  

  

  Quinnat 
  salmon. 
  — 
  On 
  December 
  31, 
  5,000 
  quinnat 
  salmon 
  eggs 
  were 
  

   received. 
  They 
  hatched 
  between 
  January 
  8 
  and 
  12 
  with 
  slight 
  loss, 
  

   and 
  on 
  May 
  28, 
  when 
  the 
  fry 
  were 
  transferred 
  to 
  the 
  ponds, 
  the 
  loss 
  

   from 
  the 
  time 
  of 
  hatching 
  amounted 
  to 
  less 
  than 
  200. 
  They 
  grew 
  very 
  

   rapidly 
  after 
  being 
  released 
  in 
  the 
  ponds, 
  and 
  at 
  the 
  close 
  of 
  the 
  year 
  

   were 
  about 
  4 
  inches 
  long. 
  

  

  Black 
  bass. 
  — 
  To 
  increase 
  the 
  output 
  of 
  the 
  station, 
  59 
  adult 
  small- 
  

   mouth 
  black 
  bass 
  were 
  transferred 
  from 
  Put-in 
  Bay 
  in 
  October. 
  They 
  

   were 
  kept 
  in 
  one 
  of 
  the 
  spring-fed 
  ponds 
  until 
  April 
  14 
  when 
  they 
  were 
  

   transferred 
  to 
  the 
  spawning-ponds, 
  which 
  had 
  been 
  prepared 
  with 
  

   artificial 
  nests. 
  Owing 
  to 
  the 
  unusually 
  cool 
  and 
  cloudy 
  weather 
  they 
  

   did 
  not 
  commence 
  nesting 
  until 
  late 
  in 
  May, 
  and 
  at 
  the 
  end 
  of 
  June 
  

   only 
  two 
  nests 
  containing 
  eggs 
  had 
  been 
  found. 
  

  

  Rock 
  bass. 
  — 
  Early 
  in 
  April 
  145 
  adult 
  rock 
  bass 
  were 
  placed 
  in 
  the 
  

   spawning-ponds. 
  These 
  were 
  also 
  afi'ected 
  by 
  cool 
  weather, 
  and 
  though 
  

   they 
  commenced 
  nesting 
  early 
  in 
  May 
  very 
  few 
  eggs 
  were 
  noticed 
  at 
  the 
  

   close 
  of 
  the 
  year. 
  

  

  Grappie. 
  — 
  Of 
  104 
  crappie 
  transferred 
  from 
  Quincy 
  Station 
  in 
  October, 
  

   there 
  remained 
  but 
  46 
  the 
  following 
  spring. 
  These 
  were 
  in 
  excellent 
  

   condition, 
  apparently, 
  but 
  so 
  far 
  they 
  have 
  shown 
  no 
  indications 
  of 
  

   spawning.
