March 1961 COMMERCIAL FISHERIES REVIEW Stop-seine gear is very efficient in that it catches 100 percent of the herring available when schools can be located inside suitable coves or on shallow beaches. Over 60 percent of the 1947 catch was taken with stop-seine gear (Scattergood 1949), and at the present time approximately 84 percent of the Maine herring catch is being taken in stop seines (Power 1958). As effective as sardlne-weir and stop-seine methods are for catching the small herring, they have a common and serious deficiency. Both methods are passive and are completely dependent upon migrations of herring to the shallow-water fishing sites. During late spring, summer, and fall, schools of herring usually migrate fromi the deeper waters of the open ocean and the bays up into the smaller coves on what is generally believed to be a feeding migration. It is during these movements that the opportunity for catching the herring is presented. Often, however, herring schools fail to run Inshore far enough to be caught with stop seines or weirs. They can frequently be located (even when fishermen inshore are ac- tively seeking fish and sardine processors are standing by in their idle plants) lying in the deeper waters of the larger bays and inlets along the coast, where they remain sometimes for periods of weeks, but fail to make the anticipated migrations up into the shallow waters. A situation of apparent scarcity often exists, therefore, when in actuality plenty of herring are to be found along the Maine coast. Stop seines and weirs, despite their shortcomings, have remained the sole gear used for taking herring for sardine processing because they perform an essential function that other types of gear cannot; they hold herring alive for periods of up to one month without serious loss of quality or total weight. The fish must be held alive for two reasons: (1) to allow their intestines to clear of food and fecal ma
