Station routine included bathythermogrE^h casts to allowable depths and 10-meter reversing thermometer casts. Aerial Scouting--Lampara Net Fishing: Work- ing In San Luis Obispo Bay, five setsofa 100-fath- om lampara net were made during daylight hours under the direction of an observer flying in the State Cessna 170. Four sets were made around schools of fish visible from the air but not from the boats. These schools were traced on a small recording fathometer prior to setting the net in an attempt to measure their mass. In each instance. the school was seen to escape the net despite the fact that it was completely surrounded. Each haul yielded only a scoop or two of fish; the shallow wa- ter set contained primari!^ anchovies and white croakers, while the deep water sets caught jack smelt and sardines. Because the schools of fish were seen to escape the net, it was felt that the catch was of scattered fish and not a portion of the school. Therefore the last set was deliberately made on a blank area; no school of fish was visible from the air and no traces were obtained on the fathometer. The resulting catch of this set was one large jack smelt. Thus, it appeared that the first 4 hauls did catch a portion of the encircled school. PRESEASON EXPLORATORY ALBACORE SURVEY (M/V N. B. Scofield Cruise 57-S-2): An exploratory survey to determine the preseason occurrence of albacore and to delineate the migration route taken by albacore tuna as they ap- proach the west coast of Lower California was made by the California Department of Fish and Game's research vessel N. B. Scofield from June 3-July 15, 1957. Oth- er objectives of the cruise were: (1) to obtain oceanographic and biological data that may be related to the occurrence of albacore; (2) locate and report banks and seamoun
