  OTTER-TRAWL 
  FISHERY. 
  

  

  the 
  nets 
  took 
  11.7 
  per 
  cent 
  and 
  the 
  lines 
  31.7 
  per 
  cent. 
  Eliminating 
  

   the 
  dogfish, 
  the 
  proportion 
  of 
  total 
  nonmarketable 
  species 
  taken 
  

   by 
  the 
  two 
  methods 
  did 
  not 
  differ 
  materially. 
  

  

  The 
  waste 
  of 
  marketable 
  species 
  too 
  small 
  for 
  sale 
  was 
  compara- 
  

   tively 
  small 
  in 
  the 
  otter-trawl 
  fishery 
  from 
  January 
  to 
  May 
  in- 
  

   clusive, 
  not 
  being 
  mxaterially 
  higher 
  than 
  the 
  catch 
  of 
  immature 
  

   fish 
  on 
  lines 
  in 
  the 
  latter 
  half 
  of 
  the 
  year, 
  but 
  from 
  June 
  to 
  Decem- 
  

   ber, 
  inclusive, 
  the 
  otter 
  trawls 
  were 
  relatively 
  almost 
  five 
  times 
  as 
  

   destructive 
  of 
  small 
  fish 
  as 
  the 
  lines. 
  

  

  On 
  the 
  vessels 
  under 
  observation 
  the 
  lines 
  took 
  no 
  young 
  cod 
  

   and 
  practically 
  no 
  young 
  haddock, 
  while 
  2.4 
  per 
  cent 
  of 
  the 
  whole 
  

   catch 
  of 
  the 
  otter 
  trawlers 
  consisted 
  of 
  young 
  cod 
  and 
  22.3 
  per 
  cent 
  

   of 
  3^oung 
  haddock 
  regarded 
  as 
  too 
  small 
  to 
  sell. 
  Stated 
  in 
  another 
  

   form, 
  40 
  per 
  cent 
  of 
  the 
  cod 
  and 
  38 
  per 
  cent 
  of 
  the 
  haddock 
  taken 
  

   by 
  the 
  otter 
  trawlers 
  from 
  June 
  to 
  December 
  were 
  fish 
  too 
  small 
  

   to 
  market. 
  From 
  January 
  to 
  May 
  but 
  3 
  per 
  cent 
  of 
  the 
  cod 
  and 
  

   11 
  per 
  cent 
  of 
  the 
  haddock 
  were 
  unmarketable 
  on 
  account 
  of 
  their 
  

   size. 
  

  

  The 
  foregoing 
  data 
  are 
  based 
  on 
  the 
  entire 
  catch 
  of 
  all 
  vessels 
  

   observed; 
  since 
  they 
  cover 
  trips 
  to 
  a 
  number 
  of 
  banks 
  and 
  the 
  

   returns 
  for 
  the 
  two 
  methods 
  of 
  fishing 
  are 
  not 
  strictly 
  comparable, 
  

   for 
  the 
  steam 
  trawlers 
  and 
  liners 
  were 
  in 
  many 
  cases 
  not 
  fishing 
  

   on 
  the 
  same 
  grounds, 
  the 
  following 
  table 
  has 
  been 
  prepared 
  :

  of 
  Marketable 
  and 
  Unmarketable
