A portion of one day was spent flying over the waters between Huntington Beach and Dana Point. On each of the 15-min- ute flights made from 12:48 to 3:05 pan. and 4:10 to 4:28 nvunbers of fish schools were counted and their visible axeameasured using an optical instrument. AIRPLANE SPOTTING FLIGHTS 57-5 (jULY 25- 28) AND 57-6 (august 6). The observations made on the two isolated sardine school groups found in the area, one off Newport Beach and the other off Laguna Beach, are listed in table 1. The fish school area, as shown in table 1, is only the first step in the develop- ment of a method of estimating the density of observed schools. As yet these figures cannot be converted into a measure of absolute density such as pounds per square foot. The resolution of this problem, however, is in
