Figure 175. Seines. Annual Average over All Stations. Spottail Shiner and Inland Silverside.
Spottail shiner decreased in average catch in 2003, but remained a common species in trawl
samples (Figure 175). The long term trend for this species is rather constant at about 6-9
individuals per trawl (Figure 176). Inland silverside also declined in 2003, continuing a slide
that began in 2000 as indicated by both average values and LOWESS plots (Figure 175, 177).
