  INSTRUCTIONS 
  FOR 
  OTTER-TRAWL 
  INVESTIGATIONS. 
  

  

  The 
  general 
  purpose 
  of 
  the 
  investigation 
  is 
  to 
  determine 
  the 
  efficiency 
  of 
  the 
  

   apparatus 
  employed 
  and 
  its 
  effects 
  upon 
  the 
  fishes 
  and 
  the 
  fishery. 
  

   The 
  principal 
  points 
  to 
  be 
  considered 
  are 
  as 
  follows 
  : 
  

  

  1. 
  The 
  defining 
  of 
  each 
  separate 
  fisliiug 
  area 
  over 
  which 
  the 
  trawl 
  was 
  

   worked. 
  If 
  within 
  sight 
  of 
  land, 
  giving 
  the 
  bearing 
  of 
  the 
  nearest 
  point 
  of 
  

   land 
  and 
  the 
  distance 
  from 
  shore. 
  If 
  out 
  of 
  sight 
  of 
  land, 
  giving 
  the 
  name 
  of 
  

   the 
  fishing 
  bank, 
  and, 
  if 
  possible, 
  the 
  latitude 
  and 
  longitude. 
  

  

  2. 
  The 
  days 
  and 
  dates 
  trawling 
  was 
  carried 
  on.

  of 
  times 
  the 
  trawl 
  was 
  lifted 
  each 
  day. 
  

  

  4. 
  The 
  length 
  of 
  time 
  the 
  trawl 
  was 
  down 
  on 
  each 
  occasion 
  before 
  lifting. 
  

  

  5. 
  The 
  speed 
  of 
  the 
  vessel 
  when 
  trawling.

  conditions 
  each 
  day. 
  

  

  7. 
  The

  fish 
  taken 
  from 
  the 
  net 
  after 
  each 
  haul. 
  

  

  8. 
  The 
  quantity 
  of 
  fish, 
  including 
  shellfish, 
  taken 
  in 
  each 
  haul, 
  showing 
  the 
  

   quantity 
  of 
  each 
  kind 
  and 
  its 
  proportion 
  to 
  the 
  whole 
  catch. 
  (This 
  should 
  be 
  

   ascertained 
  by 
  actual 
  count 
  or 
  measurement, 
  if 
  possible. 
  If 
  this 
  can 
  not 
  be 
  

   done, 
  then 
  the 
  closest 
  possible 
  aiiproximation 
  should 
  be 
  made.) 
  

  

  9. 
  The 
  quantity

  kind 
  of 
  immature 
  edible 
  fish 
  taken 
  in 
  each

  the 
  

   proportion 
  of 
  such 
  to 
  the 
  whole. 
  

  

  10. 
  What 
  disposal 
  was 
  made 
  of 
  such 
  immature

  fish 
  taken. 
  

  

  11. 
  The 
  proportion

  the 
  kinds 
  mostly 
  found 
  to 
  be 
  alive. 
  

  

  12. 
  If 
  immature 
  and 
  nonedible 
  fish 
  were 
  thrown 
  overboard, 
  the 
  percentage 
  of 
  

   each 
  kind 
  that 
  were 
  alive 
  when 
  returned 
  to 
  the 
  sea

  the 
  trawler. 
  

  

  14.

  gi-ound 
  

   in 
  succession, 
  showing 
  whether 
  the 
  second

  other 
  fishing 
  gear 
  were 
  carried 
  away

   whether 
  the 
  fishing 
  success 
  of 
  such 
  gear 
  was

  TRAWLEKS. 
  

  

  Urgent 
  representations 
  have 
  been 
  made 
  to 
  this 
  Bureau 
  to 
  the 
  effect 
  that 
  the 
  

   method 
  of 
  fishing 
  known 
  as 
  otter 
  trawling, 
  which 
  has 
  been 
  introduced 
  on 
  this 
  

   side 
  of 
  the 
  Atlantic 
  only 
  a 
  few 
  years 
  ago, 
  is 
  such 
  an 
  unduly 
  destructive 
  method 
  

   that 
  if 
  generally 
  adopted 
  the 
  lines 
  and 
  other 
  gear 
  of 
  ordinary 
  fishing 
  vessels
