  DISTEIBUTION 
  OP 
  FISH 
  AND 
  FISH 
  EGGS, 
  1913, 
  

  

  time 
  to 
  reproduce. 
  The 
  number 
  of 
  fish 
  in 
  an 
  allotment 
  is, 
  however, 
  

   a 
  variable 
  quantity, 
  depending 
  upon 
  the 
  species 
  and 
  the 
  age 
  at 
  

   which 
  distributed. 
  Brook 
  trout, 
  which 
  are 
  distributed 
  both 
  as 
  fry 
  

   and 
  fingerlings, 
  are 
  allotted 
  in 
  much 
  larger 
  numbers 
  as 
  fry 
  than 
  as 
  

   fuigerlings 
  3 
  or 
  4 
  inches 
  long. 
  Pike 
  perch, 
  which, 
  owing 
  to 
  their 
  

   excessive 
  cannibalism, 
  can 
  not 
  be 
  reared 
  and 
  are 
  consequently 
  dis- 
  

   tributed 
  as 
  fry, 
  may 
  be 
  supplied 
  in 
  lots 
  of 
  half 
  a 
  million, 
  where 
  an 
  

   equal 
  water 
  area 
  would 
  receive 
  only 
  200 
  or 
  300 
  young 
  bass 
  from 
  2 
  to 
  

   5 
  inches 
  long. 
  These 
  latter 
  larger 
  fish 
  have 
  a 
  much 
  better 
  chance 
  of 
  

   reaching 
  maturity 
  than 
  have 
  the 
  fry, 
  and 
  the 
  actual 
  value 
  for 
  stocking 
  

   purposes 
  of 
  a 
  few 
  hundred 
  fingerling 
  bass 
  may 
  therefore 
  equal 
  many 
  

   thousand 
  times 
  this 
  number 
  of 
  pike-perch 
  fry. 
  

  

  Owing 
  to 
  the 
  Bureau's 
  inability 
  to 
  produce 
  the 
  black 
  basses, 
  

   crappies, 
  catfishes, 
  and 
  sunlishes 
  in 
  sufficient 
  numbers 
  to 
  meet 
  the 
  

   demands, 
  the 
  allotments 
  of 
  such 
  species 
  are 
  necessarily 
  limited 
  to 
  

   the 
  smallest 
  number 
  needful 
  to 
  form 
  the 
  nucleus 
  for 
  a 
  brood 
  stock 
  

   for 
  the 
  water 
  area 
  to 
  which 
  assigned.
