  REPOKT 
  OF 
  COMMISSIONER 
  OF 
  FISH 
  AND 
  FISHERIES. 
  

  

  donated 
  to 
  the 
  Nevada 
  and 
  Wyoming 
  commissions. 
  The 
  balance 
  were 
  

   transferred 
  to 
  the 
  Buhith, 
  Manchester, 
  Leadville, 
  and 
  Northville 
  sta- 
  

   tions, 
  and 
  with 
  the 
  exception 
  of 
  one 
  consignment 
  to 
  Dululh 
  they 
  were 
  

   received 
  in 
  excellent 
  condition. 
  In 
  shipping 
  eggs 
  hay 
  was 
  used 
  for 
  the 
  

   outside 
  packing 
  around 
  the 
  crates, 
  owing 
  to 
  the 
  scarcity 
  of 
  sphagnum 
  

   moss 
  in 
  the 
  vicinity 
  of 
  the 
  station. 
  The 
  rest 
  of 
  the 
  season's 
  take 
  were 
  

   hatched 
  and 
  27,000 
  fry 
  were 
  distributed 
  during 
  the 
  month 
  of 
  May; 
  

   the 
  remainder 
  were 
  retained 
  for 
  distribution 
  in 
  the 
  fall, 
  and 
  at 
  the 
  close 
  

   of 
  the 
  year 
  they 
  numbered 
  90,725. 
  A 
  slight 
  epidemic 
  occurred 
  among 
  

   them 
  in 
  May, 
  but 
  it 
  was 
  checked 
  by 
  the 
  liberal 
  use 
  of 
  salt. 
  

  

  Blach 
  bass. 
  — 
  The 
  output 
  of 
  yearling 
  bass 
  in 
  the 
  fall, 
  amounting 
  to 
  

   15,600, 
  exceeded 
  that 
  of 
  any 
  previous 
  year 
  by 
  30 
  per 
  cent. 
  The 
  fry 
  were 
  

   reared 
  in 
  troughs 
  and 
  fed 
  on 
  flnely 
  grated 
  crawfish 
  collected 
  from 
  the 
  

   ponds 
  at 
  the 
  station. 
  The 
  brood 
  stock 
  of 
  this 
  species 
  was 
  increased 
  to 
  134 
  

   by 
  the 
  transfer 
  of 
  two 
  consignments 
  from 
  Quincy 
  — 
  one 
  in 
  November 
  and 
  

   one 
  in 
  March 
  — 
  and 
  on 
  April 
  they 
  were 
  distributed 
  in 
  four 
  of 
  the 
  ponds, 
  

   which 
  had 
  been 
  ])rovided 
  with 
  gravel 
  for 
  nest-building. 
  On 
  April 
  20 
  

   evidences 
  of 
  nesting 
  were 
  observed, 
  and 
  the 
  first 
  fry 
  appeared 
  May 
  19. 
  

   Owing 
  to 
  the 
  unusually 
  cool 
  weather 
  prevailing 
  during 
  the 
  spawning 
  

   season 
  and 
  to 
  an 
  insufficient 
  amount 
  of 
  natural 
  food 
  in 
  the 
  ponds, 
  the 
  

   crop 
  of 
  fry 
  at 
  the 
  close 
  of 
  the 
  year 
  is 
  very 
  small. 
  

  

  Rock 
  bass. 
  — 
  The 
  rock 
  bass 
  were 
  also 
  reared 
  in 
  troughs 
  and 
  fed 
  on 
  

   crawfish 
  through 
  the 
  summer, 
  and 
  the 
  output 
  in 
  the 
  fall 
  amounted 
  to 
  

   33,390. 
  Early 
  in 
  the 
  spring 
  artificial 
  nests, 
  similar 
  to 
  those 
  in 
  use 
  at 
  

   Wytheville, 
  were 
  introduced 
  in 
  the 
  rearing-ponds, 
  but 
  the 
  fish 
  refused 
  

   to 
  occupy 
  them. 
  On 
  April 
  20 
  they 
  commenced 
  nesting 
  in 
  the 
  gravel, 
  

   within 
  a 
  few 
  feet 
  of 
  the 
  artificial 
  nests, 
  and 
  continued 
  until 
  June. 
  

  

  Cra/ppie 
  and 
  strawberry 
  bass. 
  — 
  As 
  a 
  result 
  of 
  the 
  previous 
  spring's 
  

   spawning 
  10,000 
  young 
  fish 
  were 
  collected 
  from 
  the 
  breeding-ponds 
  

   early 
  in 
  the 
  fall. 
  They 
  were 
  very 
  small 
  and 
  weak, 
  however, 
  and, 
  though 
  

   great 
  care 
  was 
  exercised 
  in 
  handling 
  them, 
  the 
  majority 
  died, 
  leaving 
  

   only 
  3,129 
  available 
  for 
  distribution. 
  Experience 
  has 
  shown 
  that 
  the 
  

   young 
  of 
  this 
  species 
  can 
  not 
  be 
  handled 
  with 
  the 
  same 
  freedom 
  as 
  can 
  

   the 
  young 
  of 
  the 
  black 
  and 
  rock 
  bass. 
  

  

  On 
  the 
  30th 
  of 
  August 
  80 
  adult 
  crappie 
  were 
  transferred 
  to 
  the 
  sta- 
  

   tion 
  from 
  Quincy, 
  but 
  a 
  number 
  of 
  them 
  died 
  during 
  the 
  winter, 
  and 
  

   by 
  April 
  only 
  73 
  breeders 
  remained. 
  These 
  were 
  placed 
  in 
  the 
  ponds 
  

   on 
  April 
  16, 
  and 
  at 
  the 
  close 
  of 
  the 
  year 
  a 
  number 
  of 
  fry 
  were 
  observed, 
  

   though 
  no 
  nesting 
  or 
  spawning 
  had 
  been 
  noticed 
  among 
  them.
