Photograph of scale from kg Alabama spotted bass taken from Lake Perris on January 3, 1976. Arrows depict annuli. The inner annulus is considered questionable because of the lack of cutting over in the lateral field. Photograph by Jack Kelley Clark, Coopera- tive Extension, Liniversity of California at Davis. Examination of the scale sample revealed the presence of a single well defined annulus near the margin (Figure 1). There appeared to be some possibility that a centrally located (although poorly defined) annulus was also present. In our judgment, the central annulus (if valid) was laid down in 1975 while the outer annulus represents the 1976 mark. Conversely, if the central mark is not a true annulus, the outer annulus would be presumed to have been laid down in 1975. In either event, we judge this specimen to be a member of the 1974 year class (as opposed to an originally stocked specimen) and this view is supported by the following evidence: (1) the fish was unmarked (all fish originally stocked were marked by removal of the left ventral fin); (2) spotted bass from Lewis Smith Lake form easily recognizable annuli (Webb and Reeves 1975) and ex- amination of representative scale samples from the original stock prior to their introduction most often showed two well defined annuli (Figure 2); and (3) the present abundance of large spotted bass in Lake Perris lends credence to the notion that the 1974 year class grew at an exceptionally rapid Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original California.
