  the 
  bucket 
  the 
  eggs 
  will 
  absorb 
  sufficient 
  water 
  to 
  increase 
  their 
  size 
  

   about 
  40 
  per 
  cent, 
  hence 
  the 
  buckets 
  must 
  not 
  be 
  filled 
  over 
  half 
  full. 
  

  

  During 
  this 
  period 
  of 
  absorption 
  the 
  eggs 
  are 
  extremely 
  sensitive 
  

   and 
  must 
  remain 
  absolutely 
  undisturbed. 
  The 
  process 
  of 
  handling 
  

   eggs 
  by 
  the 
  improved 
  methods 
  now 
  in 
  vogue 
  is 
  described 
  in 
  some 
  

   detail 
  upon 
  pages 
  80-82 
  of 
  the 
  Alaska 
  Fisheries 
  Report 
  for 
  1911. 
  

  

  In 
  connection 
  with 
  hatchery 
  operations, 
  attention 
  is 
  again 
  called 
  to 
  

   the 
  fact 
  that 
  greater 
  care 
  ought 
  to 
  be 
  exercised 
  in 
  planting 
  young 
  fish. 
  

  

  A 
  feeling 
  has 
  often 
  prevailed 
  that 
  responsibility 
  at 
  the 
  hatchery 
  

   ceases 
  when 
  the 
  fish 
  are 
  ready 
  for 
  planting. 
  Greater 
  caution 
  and 
  

   care, 
  and 
  more 
  intelligent 
  thought 
  should 
  be 
  devoted 
  to 
  the 
  selection 
  

   of 
  suitable 
  places 
  for 
  the 
  release 
  of 
  the 
  hatchery 
  product. 
  Rather 
  

   than 
  promiscuous 
  dumping 
  of 
  the 
  fish 
  in 
  open 
  lake 
  waters, 
  it 
  would 
  

   be 
  much 
  better 
  to 
  select 
  protected 
  tributary 
  streams 
  wherein 
  to 
  

   release 
  them, 
  guarding, 
  however, 
  against 
  places 
  infested 
  with 
  trout 
  

   or 
  other 
  destructive 
  agents. 
  No 
  fish 
  culturist 
  would 
  think 
  of 
  having 
  

   even 
  one 
  Dolly 
  Varden 
  trout 
  in 
  the 
  rearing 
  pond 
  or 
  hatching 
  trough 
  

   containing 
  young 
  salmon, 
  in 
  fact 
  every 
  means 
  at 
  his 
  command 
  would 
  

   be 
  exercised 
  to 
  remove 
  the 
  trout; 
  yet 
  the 
  next 
  day, 
  perhaps, 
  he 
  wiU 
  

   complacently 
  carry 
  out 
  several 
  hundred 
  thousand 
  fine 
  young 
  salmon 
  

   and 
  unhesitatingly 
  dump 
  them 
  into 
  waters 
  where 
  trout 
  abound, 
  

   often 
  making 
  no 
  effort 
  to 
  destroy 
  a 
  single 
  one 
  of 
  the 
  trout. 
  

  

  Setting 
  gill 
  nets 
  off 
  the 
  mouths 
  of 
  streams 
  wherein 
  plants 
  are 
  

   made 
  is 
  a 
  good 
  way 
  to 
  destroy 
  trout. 
  On 
  every 
  lake 
  where 
  fish- 
  

   cultural 
  operations 
  are 
  conducted, 
  gill 
  nets 
  or 
  suitable 
  forms 
  of 
  traps 
  

   ought 
  to 
  be 
  in 
  the 
  water 
  every 
  month 
  of 
  the 
  year 
  — 
  even 
  set 
  beneath 
  

   the 
  ice 
  — 
  to 
  catch 
  Dolly 
  Varden 
  or 
  other 
  species 
  of 
  trout. 
  By 
  this 
  

   means 
  thousands 
  of 
  young 
  salmon 
  will 
  be 
  saved. 
  

  

  Hatchery 
  work 
  is 
  highly 
  perfected 
  up 
  to 
  the 
  time 
  of 
  planting, 
  but 
  

   there 
  is 
  room 
  for 
  improvement 
  in 
  the 
  latter 
  operation. 
  This 
  matter 
  

   was 
  referred 
  to 
  more 
  fully 
  in 
  the 
  Alaska 
  Fisheries 
  Report

  NEED 
  OF 
  ADDITIONAL 
  HA'J 
  CHERIES. 
  

  

  Hatcheries 
  have 
  done 
  much 
  good 
  in 
  the 
  way 
  of 
  preserving 
  the 
  

   salmon 
  industry 
  in 
  the 
  face 
  of 
  heavy 
  fishing. 
  No 
  one 
  can 
  state 
  

   definitely 
  what 
  would 
  have 
  happened 
  had 
  there 
  been 
  no 
  fish-cultural 
  

   effort, 
  but 
  considering 
  the 
  great 
  saving 
  over 
  nature's 
  method 
  it 
  seems 
  

   indisputable 
  that 
  there 
  has 
  been 
  a 
  proportionately 
  increased 
  produc- 
  

   tion 
  of 
  young 
  fish, 
  the 
  result 
  of 
  artificial 
  propagation. 
  A 
  tendency 
  

   has 
  existed, 
  however, 
  in 
  some 
  quarters 
  to 
  consider 
  hatcheries 
  as 
  a 
  

   cure-all 
  for 
  every 
  evil, 
  past, 
  present, 
  or 
  future. 
  But 
  it 
  is 
  only 
  reason- 
  

   able 
  to 
  say 
  that 
  along 
  with 
  hatcheries 
  must 
  go 
  a 
  proper 
  regulation 
  

   of 
  fishing, 
  else 
  benefits 
  are 
  to 
  a 
  greater 
  or 
  less 
  degree 
  annulled. 
  

  

  The 
  two 
  Govermnent 
  and 
  five 
  private 
  hatcheries 
  in 
  Alaska 
  are 
  

   doing 
  good 
  work 
  even 
  in 
  the 
  face 
  of 
  an 
  ever-increasing 
  commercial
