Retrieving of the long-line started at 1230 and on completion--usually 2j-3 hours--the course was set for the next station 120 miles away. While en route to the next station, during daylight hours 6 lines were trolled and a watch kept for signs of surface schools of fish and bird flocks. At night, usually commencing at 2100, a plankton tow was made, fol- lowed by 1 hour of fishing with a fine meshed dip net under a 1500-watt night light.

The cruise was designed to: (1) assess the relative abun- dance and distribution of sar- dines, anchovies, and mackerel in California and Baja Califor- nia waters; (2) tag and release yellowtail wherever available; (3) obtain young sardines in the Sebastian Viscaino Bay area for growth analysis study; (4 ) scout the area north of San QuintinBay in conjunction with the survey flight of the Department's Beech- craft airplane. A total of 169 fish schools were observed either visually or with the aid of the "Sea Scanar. " Of the schools sighted, 87 were identified as anchovy, 34 sar- dine, 23 Pacific mackerel, 20 squid, and 5 saury (see table). A total of 54 light stations were occupied and hauls with the blanket net yielded 8 sample
