  OTTER-TEAWL 
  FISHERY. 
  

  

  The 
  catch 
  of 
  demersal 
  fish 
  by 
  steam 
  trawlers 
  increased 
  constantly 
  

   during 
  the 
  period 
  from 
  1891 
  to 
  1912, 
  and 
  at 
  the 
  end 
  was 
  480 
  per 
  

   cent 
  greater 
  than 
  at 
  the 
  beginning. 
  This 
  was 
  made 
  up 
  mainly 
  of 
  

   round 
  fishes, 
  taking 
  into 
  consideration 
  those 
  species 
  only 
  which 
  

   were 
  so 
  classified 
  in 
  all 
  years. 
  If 
  to 
  these 
  were 
  added 
  the 
  species 
  

   which 
  were 
  classified 
  after 
  1903, 
  the 
  increase 
  would 
  be 
  practically 
  

   entirely 
  among 
  the 
  round 
  fishes. 
  

  

  The 
  catch 
  of 
  flat 
  fishes 
  fiuctuated, 
  but 
  there 
  was 
  a 
  practical 
  parity 
  

   between 
  1891 
  and 
  1912, 
  notwithstanding 
  a 
  heavy 
  increase 
  in 
  the 
  

   fleet 
  shown 
  in 
  another 
  place 
  in 
  this 
  report. 
  The 
  history 
  of 
  the 
  catch 
  

   of 
  the 
  principal 
  species 
  of 
  round 
  fishes 
  and 
  flat 
  fishes

  Cod 
  and 
  haddock, 
  particularly 
  the 
  former, 
  provided 
  the 
  major 
  

   part 
  of 
  the 
  recorded 
  increase 
  in 
  round 
  fishes, 
  but 
  their 
  relative 
  

   importance 
  to 
  the 
  total 
  catch 
  of 
  round 
  fishes 
  changed 
  materially. 
  

   In 
  1891 
  cod 
  constituted 
  about 
  16 
  per 
  cent 
  of 
  trawled 
  round 
  fishes, 
  

   and 
  in 
  1912 
  over 
  33 
  per 
  cent, 
  while 
  the 
  proportion 
  of 
  haddock 
  

   fell 
  from 
  75 
  per 
  cent 
  to 
  about 
  28 
  per 
  cent. 
  It 
  appears 
  from 
  this
