﻿REPORT 
  OF 
  COMMISSIONER 
  OF 
  FISH 
  AND 
  FISHERIES. 
  

  

  41 
  

  

  from 
  the 
  Chesapeake 
  Bay 
  autl 
  by 
  the 
  use 
  of 
  Turks 
  Islaud 
  salt 
  aud 
  

   fresh 
  water. 
  

  

  Most 
  of 
  the 
  fresh-water 
  fishes 
  exhibited 
  during 
  the 
  year 
  were 
  collected 
  

   at 
  various 
  points 
  on 
  the 
  Potomac, 
  though 
  several 
  consignments 
  were 
  

   received 
  from 
  the 
  stations 
  in 
  Washington 
  and 
  Wytheville, 
  Ya. 
  

  

  The 
  only 
  marine 
  fish 
  observed 
  to 
  spawn 
  in 
  the 
  aquarium 
  during 
  the 
  

   year 
  was 
  a 
  flounder. 
  This 
  occurred 
  on 
  April 
  28. 
  The 
  eggs 
  were 
  placed 
  

   in 
  a 
  small 
  aquarium 
  fitted 
  with 
  air 
  circulation, 
  but 
  they 
  failed 
  to 
  hatch, 
  

   probably 
  on 
  account 
  of 
  imperfect 
  fertilization. 
  

  

  The 
  only 
  fresh- 
  water 
  species 
  that 
  spawned 
  were 
  two 
  small 
  yellow 
  

   perch 
  — 
  on 
  April 
  1 
  and 
  2. 
  The 
  eggs 
  were 
  placed 
  in 
  the 
  McDonald 
  jars 
  

   and 
  hatched 
  without 
  difficulty. 
  

  

  It 
  is 
  deemed 
  worthy 
  of 
  mention 
  that 
  so 
  few 
  fresh- 
  water 
  fishes 
  have 
  

   ever 
  spawned 
  in 
  the 
  aquarium. 
  The 
  reason 
  for 
  this 
  is 
  attributed 
  to 
  the 
  

   use 
  of 
  alum 
  in 
  filtering 
  the 
  water, 
  since 
  the 
  fishes 
  that 
  have 
  spawned 
  

   had 
  been 
  held 
  in 
  the 
  water 
  only 
  a 
  few 
  months, 
  and 
  though 
  some 
  of 
  

   them 
  lived 
  for 
  three 
  years 
  afterwards, 
  they 
  never 
  sjiawned 
  a 
  second 
  

   time. 
  Ai)parently 
  there 
  is 
  no 
  filter 
  in 
  the 
  market 
  that 
  will 
  provide 
  a 
  

   sufficient 
  amount 
  of 
  water 
  for 
  the 
  aquarium 
  except 
  those 
  requiring 
  the 
  

   use 
  of 
  alum 
  as 
  a 
  coagulator. 
  If 
  a 
  sufl&cient 
  supply 
  of 
  cool 
  water 
  could 
  

   be 
  obtained 
  from 
  a 
  well, 
  thus 
  obviating 
  the 
  necessity 
  for 
  a 
  filter, 
  there 
  

   would 
  be 
  no 
  difficulty 
  in 
  maintaining 
  an 
  excellent 
  exhibit 
  throughout 
  

   the 
  year. 
  With 
  the 
  present 
  equipment 
  the 
  fishes 
  can 
  be 
  held 
  only 
  from 
  

   October 
  to 
  the 
  end 
  of 
  June. 
  

  

  Following 
  is 
  a 
  list

  and
