Tagging halibut. —Fish and Game Photo in any quantity during 1956 but were plentiful during the latter part of 1957 and have been abundant in 1958. New' aerial survey techniques were developed dur- ing the biennium and the program was intensified. A method for determining the aerial magnitude of pelagic fish schools was worked out, photographic ex- periments were attempted and an effort was made to use surface vessels in conjunction with the airplane. Flights during 1956 revealed only moderate concen- trations of anchovy schools most of which were ob- served in Southern California and Baja California. Re- sults of 1957 flights showed an increase of school groups in Central California late in the year, while Southern California and Baja California remained about the same as 1956. Counts of anchovy schools resulting from aerial surveys during the first half of 1958 indicate that a very large population is present off Central California. Many thousands of schools were obser\'ed from San Francisco to, and into, Mon- terey Bay. Localities south of this area also contained fair to good concentrations of fish. Even though anchovies appear to be abundant, the 1958 commercial season through June was not good. The prospect for coming \ears is good as long as this large population of young fish survives and becomes available to the fishermen. BOTTOM FISHERIES California's otter trawl fleet continued to produce more than 30 million pounds per >'ear of assorted fishes for use by local markets in a fresh and fresh frozen state. Foreign imports increased and became a deterrent to continued high production. "Tight" mar- kets characterized the latter months of the biennium. Most markets placed strict limits on species and pound- ages delivered by their vessels. Dover sole continued to be the leading species
