  In

   chiefly 
  with 
  reference 
  to 
  its 
  present 
  and 
  former 
  abundance, 
  its 
  migra 
  

   tions 
  and 
  other 
  movements, 
  its 
  spawning 
  habits, 
  its 
  food, 
  and 
  its 
  size 
  

   andimportance 
  as 
  a 
  food-fish. 
  The 
  conclusions 
  have 
  been 
  reached 
  from 
  

   a 
  consideration 
  of 
  all 
  the 
  evidence 
  obtained 
  from 
  dealers, 
  fishermen, 
  and 
  

   others, 
  supplemented 
  by 
  the 
  original 
  observations 
  of 
  the 
  party.
