The area sur- veyed by the California Department of Fish and Game's airplanes extended a- long the inshore California shore from Santa Cruz to San Diego and the area a- round Santa Cruz, Santa Rosa, San Mi- quel, Santa Catalina, San Clemente, and Coronados Islands. The flight was designed (1) to as- sess the abundance and distribution of schooling pelagic fish and to measure variations in abundance of fish schools from day to day; and (2) to experiment with aerial photography in determining area of fish schools. Weather conditions were quite variable. From May 16-19 exception- ally calm and clear weather prevailed over the entire coast. From May 20- 23 strong winds and rain squalls were encountered. Fish abundance was apparently af- lected by the various weather conditions.

This group of schools was mainly in the channel between the mainland and Santa Catalina Island but would at times come close to shore where it could be assess- ed by the Cessna. Up to 195 schools were seen in one day in this area where- as up to 3, 000 schools were seen along the coast in May of 1956. Sardine: One school group was seen between the Coro
