  Fish 
  Commission 
  Lakes, 
  Washington, 
  D. 
  C. 
  (Rudolph 
  Hessel 
  in 
  charge). 
  

  

  During 
  the 
  fall 
  months 
  the 
  following 
  fish, 
  resulting 
  from 
  the 
  crop 
  of 
  

   the 
  previous 
  spring, 
  were 
  distributed: 
  Large-mouth 
  black 
  bass, 
  38,492; 
  

   small-mouth 
  black 
  bass, 
  2,688; 
  rock 
  bass, 
  5,070; 
  shad 
  (estimated 
  num- 
  

   ber), 
  1,500,000. 
  

  

  At 
  the 
  close 
  of 
  the 
  previous 
  fiscal 
  year 
  12,270 
  young 
  large-mouth 
  

   black 
  bass 
  had 
  been 
  transferred 
  from 
  the 
  breeding-ponds 
  to 
  the 
  tanks 
  

   and 
  the 
  small 
  rearing-ponds. 
  This 
  work 
  was 
  continued 
  during 
  the 
  

   summer, 
  a 
  total 
  of 
  48,822 
  large-mouth 
  and 
  2,976 
  small-mouth 
  bass 
  being 
  

   secured. 
  

  

  The 
  losses 
  up 
  to 
  the 
  time 
  of 
  distribution 
  amounted 
  to 
  11,410, 
  of 
  which 
  

   1,080 
  were 
  the 
  small-mout*" 
  sipecies. 
  The 
  heaviest 
  mortality 
  occurred 
  

   in 
  June, 
  caused 
  by 
  the 
  higi 
  ,mperature 
  and 
  the 
  muddy 
  condition 
  of 
  

   the 
  water. 
  Their 
  food 
  during 
  the 
  early 
  summer 
  consisted 
  of 
  chopped 
  

   fish 
  (carp 
  and 
  tench 
  reared 
  at 
  the 
  station), 
  and 
  when 
  the 
  supply 
  was 
  

   exhausted, 
  fishes 
  purchased 
  from 
  the 
  market 
  were 
  substituted. 
  The 
  

   bass 
  refused 
  to 
  take 
  the 
  fresh- 
  water 
  species, 
  but 
  the 
  various 
  salt-water 
  

   fishes, 
  particularly 
  the 
  butter-fish 
  and 
  the 
  sea 
  trout, 
  proved 
  very 
  accept-
