Table 2.-Seasonal variation in relative abundance of fishes observed along a transect line. 

 Samples are pooled over day and night transects by trimonthly intervals generally 

 coinciding with periods of oceanographic change off Santa Barbara. Kendall's H^ coefficient 

 of rank concordance among seasons = 0.77 (P«0.005).

Table 3.— Day-night variation in abundance of fishes observed along a transect line. Samples 

 are pooled over seasonal intervals (see Table 2). Symbols in the "Difference" column indicate for 

 each species whether the numbers of individuals observed during the day, ordered among all 

 transects, were significantly greater than (>), less than (<), not significantly different from ( = ), 

 or too few to compare with (NC) the numbers observed at night (Wilcoxon signed-rank test for 

 paired observations, P^O.05).
