  Percentage

  Marketable 
  and 
  Unmarketable 
  Species 
  of 
  Fishes 
  Taken 
  

   BY 
  Otter 
  Trawls 
  and 
  Trawl 
  Lines, 
  Respectively, 
  in 
  1913, 
  on 
  Certain 
  

  

  Vessels.

  This 
  is 
  a 
  record 
  of 
  the 
  catch, 
  not 
  of 
  the 
  fares 
  landed, 
  and 
  it 
  

   includes 
  the 
  marketable, 
  the 
  unmarketably 
  small 
  of 
  the 
  marketable 
  

   species, 
  and 
  the 
  species 
  which 
  have 
  no 
  present 
  market 
  value. 
  The 
  

   question 
  of 
  the 
  sizes 
  of 
  these 
  fish 
  will 
  be 
  considered 
  later. 
  All 
  cod, 
  

   haddock, 
  hake, 
  pollock, 
  cusk, 
  halibut, 
  and 
  sole 
  of 
  suitable 
  size 
  are 
  

   saved, 
  while 
  wolf 
  fish, 
  butterfish, 
  and 
  rosefish 
  are 
  sometimes 
  saved 
  

   and 
  sometimes 
  thrown 
  away. 
  The 
  " 
  nonmarketable 
  species 
  " 
  are 
  all 
  

   edible 
  fish, 
  but 
  are 
  not 
  utilized 
  in 
  American 
  markets. 
  

  

  It 
  will 
  be 
  observed 
  that 
  there 
  is 
  but 
  little 
  change 
  in 
  the 
  pro- 
  

   portions 
  of 
  marketable 
  and 
  nonmarketable 
  species 
  taken 
  by 
  the 
  

   otter 
  trawls 
  in 
  the 
  first 
  and 
  second 
  halves 
  of 
  the 
  year, 
  respectively, 
  

   but 
  that 
  during 
  the 
  period 
  from 
  June 
  1 
  to 
  December 
  31 
  the 
  trawl 
  

   lines 
  catch 
  a 
  much 
  larger 
  proportion 
  of 
  nonmarketable 
  species 
  than 
  

   do 
  the 
  otter 
  trawls, 
  the 
  difference 
  being 
  due 
  to 
  the 
  larger 
  number 
  

   of 
  dog-fishes 
  taken 
  on 
  the 
  lines, 
  21.2 
  per 
  cent 
  of 
  the 
  whole 
  catch 
  

   as 
  compared 
  with 
  2.8 
  per 
  cent 
  taken 
  in 
  the 
  nets. 
  During 
  this 
  period 
  

   the 
  otter 
  trawls 
  observed 
  toolv 
  88.2 
  per 
  cent 
  of 
  marketable 
  species 
  

   and 
  the 
  trawl 
  lines 
  68.3 
  per 
  cent, 
  and 
  of 
  the 
  nonmarketable 
  species
