The cunner, Tautogolabrus adspersus (Walbaum), also known as the chogset or bergall, is commonly found around wharves and docks and on rocky bottoms along the northeastern coast of North America. It is distributed from Newfoundland southward to the mouth of the Chesapeake Bay, with a major center of abundance in the Massachusetts Bay area. In these northern waters, cunners are most numerous in shallow inshore areas, although they are frequently taken near wrecks and shoals up to 30 miles at sea. There is little evidence in support of seasonal migration patterns and individuals remain near their areas during their formative years. At one time, the cunner was a favorite fish of New England anglers. During the 1880's between 200,000 and 300,000 pounds of cunner were taken in the New England commercial harvest. However, since the turn of the century, commercial catches have been negligible because of poor demand.

Catch data of the Japanese tuna longline fishery from 1964 to 1967 were analyzed to determine the distribution, abundance, and movement of skipjack tuna, Katsuwonus pelamis, in offshore waters of the Pacific Ocean. Large skipjack tuna, as well as larvae, were found to be concentrated mainly in the east central equatorial Pacific. Movement of skip-jack tuna stocks was determined by following the shifting of high-CPUE (catch per unit effort) cells from one quarter to the next. The apparent movement of skipjack tuna stocks in the Pacific appeared to coincide with the circulation of the major ocean currents; counterclockwise in the southern hemisphere and clockwise in the northern hemisphere, except in the eastern Pacific where the current flow is counterclockwise. The movement patterns of high CPUE suggested that skipjack tuna adults or their progeny could move from one area to the next. The movement pattern was used also to determine the probable migratory routes followed by skipjack tuna tagged in the eastern Pacific and recovered near the Hawaiian and Christmas islands.
