It will be seen that an increased proportion of ‘* small” is visible 
throughout the table, except in three instances. It is greatest in the 
case of plaice, and least in that of haddock. In the case of the 
last-named, the comparatively small increase in the proportion of 
small fish may be accounted for if we remember that certain years 
within the earlier period, namely, 1906 and 1907, were 
remarkable for the phenomenal abundance of small haddock.
