At night 30-minute tows were made except in the NEPAS survey area. Here they were reduced to 15 minutes because of the large samples obtained and even then it was frequently not practical to preserve more than part of the sample. For example, a 20-25 liter sample was taken in the 15-minute tow at 37 09' N. latitude, 128 34' W. longitude and only two liters were preserved. Pairs of 15-minute surface tows bracketing the 58 -60 F. isotherms were al- so made on all two legs. On one they were omitted because of rough weather, on the other they were omitted because of the dense schools of Velella. Whenever the vessel hove-to at night an estimate of the number and size of the saury under the ship's lights were made every two hours. i^i :^ 1^ ^ :^ MARQUESAN SARDINE DSfTRODUCTION IN HAWAIIAN WATERS SHOWS SIGNS OF SUCCESS: The capture of six large Marquesan sardines in Hawaiian waters on September 9 by two fishermen while fishing for moi near Barbers Point aroused the interest of the Service's Pacific Oceanic Fishery Investigations (POFI) and the Ter- ritorial Division of Fish and Game. The captures are the first concrete evidence that the newly-introduced species is surviving in Hawaiian waters. The desirability of the species as skipjack (aku) bait was first established in the spring of 1954, when a Service research vessel Charles H. Gilbert surveyed the tuna baits of the Marquesas, Tuamotu, and Society islands. The sardine was found to be a- bundant in the Marquesas Is- lands, lying about 2,000 miles south and east of Hawaii. There, they generally occurred along sheltered sandy beaches. After consultations initiated by t
