Total season landings from Southern California-Baja Cali- fornia should improve substantially from 1966 (the poorest since 1947), reflecting a south- ward trend in distribution of fish this year. Oregon production probably will fall off from last year'9 record, reflecting a return to cooler, more normal oceanographic condi- tions. Fragmentary data on year-class rep- resentation suggests that fish abundance may be average for all size groups entering the fishery; thus, total U. S. West Coast landings are expected to be near the 1944-65 average of 42,000,000 pounds (21,000 tons). Bluefin Tuna In previous years, the staff restricted its forecasts for bluefin tuna solely to the South- ern California offshore region. This year, however, it is attempting to provide the same kind of statements as for albacore. The high-seas purse seine fleet already has begun to assemble in the Cape San Lucas- Cape San Lazaro, Baja California offshore region. At present, the boats are reported to be working in warm water on yellowfinand skipjack, but unconfirmed rumors report bluefin schools appearing in the 65°-670 F. water off Point Tosco (see Figure 2). For the past 4 years, oceanographic conditions in this region have created a zone of 650-67° F. water extending from the northwest, approach- ing the coast between Cape San Lazaro and Cape San Lucas. This region is expected to produce bluefin again this season, and the first commercial action should be well under- way by Memorial Day, winds and seas per- mitting. Coastal upwelling has been acceler- ated substantially during the last 4-6 weeks in this area, due largely to stronger north-
