  The 
  table 
  of 
  total 
  quantities 
  shows 
  that 
  there 
  was 
  a 
  decrease 
  

   in 
  all 
  fishes 
  excepting 
  the 
  cod, 
  but 
  as 
  is 
  seen 
  from 
  a 
  comparison 
  

   of 
  the 
  table 
  of 
  average 
  catches 
  per 
  voyage 
  this 
  was 
  in 
  part 
  due 
  

   to 
  a 
  decrease 
  in 
  fishing 
  activity. 
  Nevertheless, 
  while 
  there 
  appears 
  

   to 
  have 
  been 
  an 
  increase 
  in 
  the 
  cod, 
  as 
  measured 
  by 
  the 
  catch 
  per 
  

   unit 
  of 
  effort, 
  there 
  were 
  equally 
  considerable 
  decreases 
  in 
  the 
  had- 
  

   dock 
  and 
  plaice 
  as 
  measured 
  by 
  the 
  same 
  standard. 
  In 
  1913 
  there 
  

   was 
  a 
  further 
  development 
  of 
  these 
  tendencies, 
  and 
  while 
  there 
  was 
  

   a 
  heavy 
  increase 
  in 
  the 
  total 
  catch 
  of 
  cod, 
  due 
  to 
  increased 
  fishing 
  

   activity, 
  there 
  were 
  material 
  decreases 
  in 
  the 
  total 
  catches 
  of 
  had- 
  

   dock 
  and 
  plaice, 
  and 
  very 
  heavy 
  decreases 
  in 
  the 
  average 
  quantities 
  

   per 
  voyage, 
  especially 
  in 
  plaice, 
  of 
  which 
  but 
  half 
  as 
  many 
  were 
  

   taken 
  as 
  in 
  1906.
