The smallest sardines collected (25 mm. standard length, 1 inch total length) were taken from the stomachs of Pacific mackerel at San Quintin Bay. Although nowhere very abundant, sardines were most frequently encountered in Sebastian Viscaino Bay and at Cedros Island. Throughout the area the sardine abundance was about the same as in 1954. Pacific mackerel, the most abundant species in the area surveyed, were sam- pled from Sebastian Viscaino Bay in the south to Point San Miguel in the north. Out of the 15 Pacific mackerel sam- ples, 12 contained young fish of either the 1954 or 1955 year- classes. Northern anchovies were taken throughout the range of the survey and the two sam- ples of jack mackerel were taken at approximately the northern and southern limits of the cruise. Yellowtail were encountered at only two stations and 37 hook- and-line fish were marked and released at West San Benito Is- land, and six troll-caught fish were marked and released around the southern part of Cedros Is- land. A juvenile yellowtail (3;j- inch in length) was dipped from the bait tank during the course of fishing activities. Exact position of its capture is unknown but a check of baiting stations indicated it must have come from the south- ern area of Cedros Island. The Yellowfin traveled a total of 546 miles scouting for fish schools--194 schools were ob- served, of which it was estimated that 15 contained sardines, 78 mackerel, 19 anchovies, 3 squid, 58 sauries, and 21 unknown spe- cies. Scouting and sampling were considerably hampered by strong winds and rough water between Point Canoas and San Quintin Bay, but weather conditions were favor- able throughout the rest of the area surveyed. Surface temperatures, bathythermograph casts, and reversing thermometer casts were taken at each station regard
