Results of the cluster analysis of the top 40 fish species or recruits based on co-occurrences in station/ depth strata samplescollected from July 1994 to April 1999 in San Diego Bay (r = new recruits of the species). Standing Stock Estimates All Fish Species.—Over the entire bay for all five years, the total best estimate of numerical density was (Table 11). Based on a surface area of approximately 4858 ha, San Diego Bay, on average, contained almost 85 million fish during this time. Most of the individuals are made up of northern anchovies (42 million), but there were also, again on average, almost 18 million slough anchovies, 10 million topsmelt, 3 million sardines, 3 million arrow gobies, and nearly 2 million shiner surfperch. Among the most common, higher-level carni- vores, there are about 280,000 round stingrays, 169,000 spotted sand bass, 133,000, barred sand bass, and almost 80,000 California halibut. The total best estimate of biomass density was g/m2 (Table 12). Again, based on area,
