  FISHES 
  OF 
  THE 
  YELLOWSTONE 
  NATIONAL 
  PAKK. 
  

  

  Mary 
  Trowbridge 
  Townsend 
  (1. 
  c.) 
  mentioned 
  one 
  from 
  the 
  Firehole 
  

   River: 
  

  

  A 
  good 
  4-pounder, 
  and 
  unusual 
  marking, 
  large 
  yellow 
  spots 
  encircled 
  l)y 
  black, 
  

   with 
  great 
  brilliancy 
  of 
  iridescent 
  color.

  I 
  took 
  afterward 
  several 
  of 
  the 
  

   same 
  variety, 
  known 
  in 
  the 
  park 
  as 
  the 
  Von 
  Behr 
  trout, 
  and 
  which 
  I 
  have 
  since 
  found 
  

   to 
  be 
  the 
  same 
  Salmofario, 
  the 
  veritable 
  trout 
  of 
  Izaak 
  Walton. 
  

  

  8. 
  Lake 
  Trout 
  (Salvelinus 
  namaycush). 
  

  

  The 
  lake 
  trout, 
  otherwise 
  known 
  as 
  laker, 
  lunge, 
  togue, 
  mackinaw 
  . 
  

   trout, 
  etc., 
  is 
  of 
  wide 
  northern 
  distribution. 
  In 
  British 
  America 
  it 
  

   rano;es 
  from 
  the 
  Atlantic 
  to 
  the 
  Pacific 
  coasts 
  and 
  northward 
  to 
  the 
  

   Arctic 
  Ocean. 
  In 
  the 
  United 
  States 
  it 
  is 
  found 
  in 
  many 
  of 
  the 
  larger 
  

   and 
  deeper 
  lakes 
  in 
  New 
  England, 
  New 
  York, 
  and 
  in 
  the 
  Great 
  Lakes 
  

   Basin, 
  and 
  in 
  a 
  few 
  locahties 
  in 
  the 
  Western 
  States, 
  as 
  Montana 
  and 
  

   Idaho. 
  It 
  occurs 
  also 
  in 
  Alaska. 
  It 
  has 
  also 
  been 
  spread 
  by 
  fisli- 
  

   cultural 
  operations 
  into 
  waters 
  where 
  it 
  did 
  not 
  previously 
  exist.

  Lake 
  trout. 
  

  

  The 
  only 
  plants 
  of 
  this 
  fish 
  in 
  the 
  Yellowstone 
  Park 
  seem 
  to 
  liave 
  been 
  

   30,012 
  in 
  Shoshone 
  Lake 
  and 
  12,013 
  in 
  Lewis 
  Lake 
  in 
  1890. 
  

  

  It 
  is, 
  as 
  its 
  name 
  implies, 
  a 
  lake 
  rather 
  than 
  a 
  stream 
  fish. 
  In 
  

   some 
  waters 
  it 
  attains 
  a 
  very 
  large 
  size. 
  Examples 
  weighing 
  over 
  

   100 
  pounds 
  have 
  been 
  reported 
  from 
  the 
  Great 
  Lakes, 
  and 
  in 
  former 
  

   years 
  the 
  average 
  weight 
  of 
  the 
  fish 
  in 
  the 
  commercial 
  fisheries 
  of 
  

   those 
  waters 
  was 
  stated 
  at 
  20 
  to 
  30 
  pounds. 
  At 
  this 
  time, 
  however, 
  

   10 
  to 
  15 
  pounds 
  can 
  be 
  considered 
  large. 
  

  

  Its 
  large 
  size 
  affords 
  its 
  chief 
  attraction 
  as 
  a 
  game 
  fish, 
  for 
  it 
  is 
  

   not 
  ordinarily 
  a 
  very 
  active 
  fighter, 
  although 
  a 
  powerful 
  antagonist. 
  

   It 
  is 
  usually 
  caught 
  by 
  deep 
  trolling, 
  but 
  is 
  sometimes 
  found 
  at 
  the 
  

   surface 
  and 
  is 
  occasionally 
  taken 
  on 
  an 
  artificial 
  fiy. 
  Opinions 
  differ 
  

   regarding 
  its 
  table 
  qualities, 
  and, 
  as 
  with 
  most 
  fishes, 
  much 
  depends 
  

   upon 
  how 
  it 
  is 
  prepared 
  and 
  cooked. 
  It 
  is 
  a 
  very 
  oily 
  fish 
  and 
  often 
  

   of 
  an 
  unpleasant, 
  strong, 
  oily 
  flavor. 
  This 
  may 
  be 
  obviated, 
  how- 
  

   ever, 
  by 
  removing 
  the 
  skin 
  before 
  the 
  fish 
  is 
  cooked. 
  The 
  best 
  

   method 
  of 
  cooking 
  it 
  is 
  by 
  boiling, 
  serving 
  with 
  mayonnaise 
  dressing 
  

   or 
  egg 
  sauce.
