  WHITE 
  SEA. 
  

  

  The 
  fishery 
  by 
  English 
  vessels 
  in 
  this 
  region 
  was 
  conducted 
  solely 
  

   by 
  steam 
  trawlers, 
  and, 
  considering 
  steam 
  vessels 
  only, 
  it 
  ranked 
  

   eighth 
  in 
  catch 
  among 
  the 
  14 
  enumerated 
  regions 
  in 
  1906 
  and 
  sixth 
  

   in 
  1912. 
  In 
  1906 
  there 
  were 
  41 
  voyages 
  to 
  the 
  White 
  Sea, 
  aggregat- 
  

   ing 
  1,129 
  days, 
  and 
  with 
  an 
  average 
  length 
  of 
  27.5 
  days. 
  In 
  1912 
  

   there 
  were 
  212 
  voyages, 
  an 
  increase 
  of 
  419 
  per 
  cent, 
  aggregating 
  

   5,490 
  days 
  of 
  absence 
  from 
  port, 
  an 
  increase 
  of 
  386

  cent, 
  and 
  

   having 
  an

  This 
  fishery 
  was 
  originally 
  undertaken 
  primarily 
  for 
  plaice, 
  which 
  

   constituted 
  over 
  86 
  per 
  cent 
  of 
  the 
  total 
  catch 
  in 
  1906, 
  but 
  while 
  the 
  

   quantity 
  of 
  this 
  species 
  had 
  increased 
  about 
  183 
  per 
  cent 
  in 
  1912 
  the 
  

   catch 
  of 
  cod 
  and 
  haddock 
  had 
  increased 
  more 
  rapidly 
  and 
  plaice 
  

   comprised 
  less 
  than 
  53 
  per 
  cent 
  of 
  the 
  combined 
  catch 
  of 
  the 
  three 
  

   species 
  in 
  1912.
