lected during the year by the local agents and published in monthly 
bulletins showing by species and fishing grounds the quantities and

The following tables present in detail, by fishing grounds and by 
months, the products of the vessel fisheries of Boston and Gloucester, 
Mass., and Portland, Me., for the calendar year 1917. The weights 
of fresh and salted fish given in these statistics represent the fish as 
landed from the vessels, and the values are those received by the 
fishermen. The grades, or sizes, given for certain species are those
