  OTTER-TEAWL 
  FISHERY. 
  

  

  ings 
  of 
  demersal 
  fishes 
  of 
  all 
  Scotland 
  in 
  1891, 
  and 
  about 
  63.3 
  per 
  

   cent 
  in 
  1912. 
  Cod 
  and 
  haddock 
  landed 
  on 
  the 
  east 
  coast 
  in 
  1891 
  con- 
  

   stituted 
  nearly 
  61 
  per 
  cent 
  of 
  Scottish 
  round 
  fishes 
  and 
  in 
  1912 
  

   nearly 
  57 
  per 
  cent. 
  In 
  1891 
  the 
  flat 
  fishes 
  enumerated 
  comprised 
  

   about 
  43 
  per 
  cent, 
  and 
  in 
  1912, 
  25 
  per 
  cent 
  of 
  the 
  country's 
  landing 
  of 
  

   flat 
  fishes. 
  Furthermore, 
  the 
  catch 
  of 
  each 
  of 
  these 
  species 
  on 
  the 
  

   east 
  largely 
  exceeds 
  the 
  catch 
  in 
  all 
  other 
  regions. 
  For 
  these 
  reasons, 
  

   it 
  is 
  necessary 
  to 
  consider 
  these 
  fishes 
  only 
  in 
  discussing 
  the 
  fluctua- 
  

   tions 
  of 
  the 
  fishery. 
  

  

  Catch 
  per 
  Annum 
  at 
  the 
  Beginning 
  and 
  Ending 
  of 
  Certain 
  Periods 
  of 
  Each 
  

   OF 
  the 
  More 
  Important 
  Species 
  of 
  Demersal 
  Fishes 
  Landed 
  on 
  the 
  East 
  

   Coast 
  of 
  Scotland. 
  

  

  From 
  the 
  foregoing 
  it 
  is 
  apparent 
  that 
  both 
  the 
  cod 
  and 
  haddock, 
  

   but 
  especially 
  the 
  former, 
  landed 
  on 
  the 
  east 
  coast 
  of 
  Scotland, 
  

   exhibited 
  material 
  increases 
  in 
  total 
  quantity 
  between 
  1891 
  and 
  1912. 
  

   and 
  this 
  increase 
  occurred 
  in 
  all 
  of 
  the 
  periods 
  considered 
  excepting 
  

   from 
  1898 
  to 
  1901 
  in 
  the 
  case 
  of 
  the 
  cod, 
  and 
  1906 
  to 
  1912 
  in 
  the 
  case 
  

   of 
  the 
  haddock. 
  Halibut 
  increased 
  for 
  the 
  whole 
  period 
  and 
  showed 
  

   a 
  recession 
  only 
  between 
  1901 
  and 
  1903, 
  while 
  flounder, 
  plaice, 
  and 
  

   brill 
  decreased 
  on 
  the 
  whole 
  and 
  showed 
  improvement 
  between 
  1901
