  KEPORT 
  OF 
  THE 
  COMMISSIONER 
  OF 
  FISHERIES. 
  

  

  purchased 
  from 
  commercial 
  fishermen 
  and 
  allowed 
  to 
  ripen 
  in 
  the 
  

   spawning 
  pool 
  at 
  the 
  station, 
  the 
  capacity 
  of 
  wliich 
  had 
  been 
  enlarged 
  

   during 
  the 
  summer 
  and 
  fall. 
  The 
  total 
  yield 
  of 
  eggs 
  from 
  this 
  source 
  

   was 
  259,366,000. 
  Late 
  in 
  November 
  the 
  steamer 
  Phalarope, 
  with 
  a 
  

   crew 
  of 
  five 
  spawn 
  takers, 
  was 
  stationed 
  near 
  Sagamore, 
  Mass., 
  for 
  

   the 
  collection 
  of 
  eggs 
  from 
  the 
  cod 
  fishermen 
  operating 
  in 
  that 
  field. 
  

   Owing 
  to 
  the 
  cHmatic 
  conditions 
  encountered, 
  however, 
  only 
  5,276,000 
  

   were 
  secured, 
  and 
  on 
  January 
  9 
  the 
  field 
  work 
  was 
  abandoned. 
  In 
  

   the 
  course 
  of 
  the 
  season 
  4,130,000 
  eggs 
  were 
  transferred 
  to 
  the 
  

   Gloucester 
  station, 
  and 
  from 
  the 
  remaining 
  stock 
  182,312,000 
  cod 
  fry 
  

   were 
  hatched 
  and 
  hberated 
  in 
  the 
  coastal 
  waters 
  of 
  Massachusetts. 
  

  

  Wliile 
  the 
  flatfish 
  operations 
  in 
  the 
  fields 
  operated 
  from 
  the 
  Woods 
  

   Hole 
  station 
  were 
  greatly 
  retarded 
  by 
  unfavorable 
  weather, 
  and 
  fewer 
  

   eggs 
  were 
  secured 
  than 
  in 
  the 
  previous 
  year, 
  tlie 
  final 
  results 
  in 
  the 
  

   number 
  of 
  fry 
  distributed 
  were 
  over 
  twice 
  as 
  great. 
  The 
  installation 
  

   of 
  fyke 
  nets 
  for 
  the 
  capture 
  of 
  brood 
  fish 
  was 
  not 
  accomplished 
  in 
  

   southern 
  Massachusetts 
  until 
  late 
  in 
  January, 
  and 
  there 
  were 
  times 
  dur- 
  

   ing 
  the 
  next 
  two 
  months 
  when 
  the 
  nets 
  could 
  not 
  be 
  operated 
  because 
  of 
  

   accumulations 
  of 
  ice. 
  The 
  severe 
  weather 
  also 
  delayed 
  the 
  work 
  and 
  

   curtailed 
  the 
  egg 
  collections 
  on 
  the 
  Rhode 
  Island 
  and 
  Connecticut 
  

   shores. 
  The 
  eggs 
  from 
  all 
  sources 
  numbered 
  507,440,000 
  which 
  pro- 
  

   duced 
  373,230,000 
  fry, 
  a 
  hatch 
  of 
  73 
  per 
  cent. 
  

  

  The 
  efforts 
  in 
  connection 
  with 
  mackerel 
  hatching 
  at 
  the 
  Woods 
  

   Hole 
  station 
  were 
  confined 
  to 
  fields 
  m 
  the 
  immediate 
  vicinity; 
  all 
  

   available 
  spawn 
  was 
  taken 
  from 
  local 
  traps, 
  and 
  from 
  the 
  6,521,000 
  

   eggs 
  secured 
  2,510,000 
  fry 
  were 
  hatched 
  and 
  liberated 
  in 
  local 
  waters 
  

  

  PROPAGATION 
  OF 
  TROUTS 
  AND 
  BASSES. 
  

  

  Spawning 
  operations 
  at 
  the 
  various 
  stations 
  devoted 
  to 
  the 
  propa- 
  

   gation 
  of 
  the 
  trouts 
  were 
  highly 
  satisfactory. 
  At 
  the 
  Wytheville, 
  Va., 
  

   station 
  approximately 
  2,500,000 
  rainbow-trout 
  eggs 
  were 
  secured, 
  the 
  

   largest 
  number 
  ever 
  taken 
  by 
  the 
  Bureau 
  from 
  the 
  domesticated 
  stock 
  

   of 
  a 
  single 
  station. 
  Substantial 
  gains 
  were 
  also 
  made 
  at 
  the 
  Man- 
  

   chester, 
  Iowa, 
  station 
  in 
  the 
  output 
  of 
  this 
  species, 
  the 
  eggs 
  taken 
  being 
  

   fully 
  a 
  million 
  in 
  excess 
  of 
  those 
  of 
  the 
  previous 
  year. 
  Collections 
  of 
  

   eggs 
  from 
  wild 
  rainbow 
  trout 
  in 
  fields 
  contiguous 
  to 
  the 
  Leadville, 
  

   Colo., 
  and 
  Bozeman, 
  Mont., 
  stations 
  were 
  greatly 
  curtailed 
  by 
  heavy 
  

   storms 
  and 
  liigh 
  water 
  m 
  the 
  lakes 
  and 
  streams 
  during 
  the 
  spawning 
  

   season. 
  

  

  The 
  work 
  with 
  rainbow 
  trout 
  on 
  the 
  Klamath 
  River, 
  Cal., 
  was 
  

   practically 
  a 
  failure, 
  not 
  because 
  of 
  any 
  diminution 
  in 
  the 
  numbers 
  of 
  

   brood 
  fish, 
  but 
  because 
  they 
  spawned 
  for 
  the 
  most 
  part 
  in 
  the 
  main 
  

   river 
  instead 
  of 
  ascending 
  tributary 
  streams 
  where 
  they 
  would 
  have 
  

   been 
  accessible 
  for 
  egg-taking 
  purposes. 
  

  

  The 
  cultivation 
  of 
  the 
  brook 
  trout 
  in 
  Colorado, 
  which 
  is 
  the 
  only 
  

   State 
  where 
  extensive 
  collections 
  of 
  eggs 
  are 
  made 
  from 
  wild 
  stock, 
  

   was 
  conducted 
  under 
  unusually 
  favorable 
  weather 
  conditions, 
  and 
  

   over 
  6,000,000 
  eggs 
  of 
  fine 
  quahty 
  were 
  secured. 
  As 
  in 
  previous 
  years, 
  

   a 
  large 
  part 
  of 
  the 
  brook-trout 
  eggs 
  handled 
  at 
  the 
  Bureau's 
  stations 
  

   are 
  purchased 
  from 
  dealers, 
  this 
  course 
  having 
  proved 
  more 
  econom- 
  

   ical 
  in 
  most 
  cases 
  than 
  reliance 
  upon 
  collections 
  from 
  wild 
  fish. 
  

  

  Preparations 
  for 
  the 
  conduct 
  of 
  black-spotted 
  trout 
  work 
  in 
  the 
  

   Yellowstone 
  Park 
  were 
  taken 
  up 
  in 
  June, 
  but 
  most 
  of 
  the 
  eggs 
  were
