Figure 2 interprets the trend of the kelp bass fishery in terms of fish per angler-day. There are many factors that determine the trend, which over a long period of time, tend to balance out. No data were available during the war period. The trend lines are calculated from the data gathered from a wide area, from Point Dume above Malibu Beach to a point several miles south of San Clemente and from the islands of Santa Catalina and San Clemente. Catch trends from limited areas vary con- siderably. The slopes of the lines for the periods 1936-1940 and 1946- 1950 are very similar and indicate a rapid decline. For the latter time interval, however, this downward slope results from the high return in l!»4(i immediately following the curtailment of sport fishing during the war years. A line fitted to the years 1946-195] has a lessened decline and if a line were fitted to the records for 1947-1951 there would be an up- ward trend. Presumably the stocks of bass accumulated on the fishing grounds between 1940 and l!)4(i because of lessened fishing effort. These were quickly reduced in numbers but have held their own since 1!»47 with indications of a slight recovery. As indicated in the following discussion not all grounds have been fished with equal intens
