Considering this longer period, it will be seen that 40 OTTER-TRAWL FISHERY. the average catch per trip fell rather sharply from 1891 to about1896 to 1897, but that since those years there has been a net in-crease both on the banks fished by the steam trawlers and on thosewhich are rarely or never so fished. The sharpest fluctuations,however, are shown on the banks and during the period coveredby the otter-trawl fishery. On Georges Bank, South Channel, and.
