﻿FISHES 
  OF

  YELLOWSTONE 
  NATIONAL 
  FAKK.

  were 
  Loch 
  Leven 
  trout. 
  There 
  are 
  parallel 
  mstaiices 
  of 
  such 
  mis- 
  

   taken 
  identity 
  in 
  this 
  country 
  in 
  respect 
  to 
  other 
  species, 
  and 
  so-called 
  

   Loch 
  Leven 
  trout 
  have 
  been 
  propagated 
  for 
  a 
  long 
  time 
  in 
  this 
  

   country. 
  In 
  the 
  early 
  years 
  the 
  progeny 
  of 
  Loch 
  Leven 
  eggs 
  could 
  

   easily 
  be 
  distinguished 
  from 
  brown 
  trout 
  hatched 
  at 
  the 
  same 
  time, 
  

   especially 
  when 
  they 
  had 
  attamed 
  a 
  few 
  inches 
  in 
  length. 
  Recently, 
  

   however, 
  there 
  is 
  reason 
  to 
  suspect 
  that 
  many 
  of 
  the 
  so-called 
  Loch 
  

   Leven 
  plants 
  have 
  been 
  brown 
  trout. 
  Be 
  that 
  as 
  it 
  may, 
  trout 
  

   under 
  each 
  name 
  have 
  been 
  introduced 
  into 
  Yellowstone 
  Park 
  waters 
  

   and 
  there 
  are 
  records 
  of 
  both 
  having 
  been 
  subsequently 
  taken.

  In 
  describmg 
  the 
  fishing 
  in 
  the 
  Firehole 
  River, 
  Mary 
  Trowbridge 
  

   Townsend 
  said: 
  

  

  One 
  other 
  fish 
  proved 
  a 
  complete 
  surprise. 
  He 
  was 
  of 
  silvery 
  gray 
  color, 
  covered 
  

   with 
  small 
  black 
  crescents. 
  Some 
  park 
  fishermen 
  called 
  him 
  a 
  Norwegian 
  trout, 
  

   others 
  the 
  Loch 
  Leven. 
  Any 
  country 
  might 
  be 
  proud 
  to 
  claim 
  him 
  with 
  his 
  har- 
  

   monious 
  proportions, 
  game 
  fighting 
  qualities, 
  and 
  endtu-ance. 
  

  

  This 
  trout 
  is 
  naturally 
  a 
  lake 
  fish 
  and 
  its 
  peculiarities 
  would 
  sug- 
  

   gest 
  a 
  peculiar 
  environment. 
  Wliether 
  it 
  will 
  develop 
  and 
  thrive 
  in 
  

   streams 
  and 
  retain 
  its 
  peculiarities 
  is 
  uncertain. 
  As 
  a 
  game 
  fish 
  it 
  

   is 
  not 
  excelled 
  by 
  any 
  of 
  its 
  introduced 
  congeners 
  and 
  as 
  a 
  food 
  fish, 
  

   in 
  its 
  native 
  waters 
  at 
  least, 
  it 
  is 
  unsurpassed 
  in 
  delicacy 
  of 
  flavor. 
  

   The 
  Loch 
  Leven 
  is 
  primarily 
  an 
  insect 
  feeder 
  and 
  preeminently 
  an 
  

   artificial-fly 
  fish. 
  

  

  It 
  has 
  been 
  introduced 
  into 
  park 
  waters 
  as 
  follows: 
  

  

  1889, 
  Firehole 
  River,
