Figure 169. Seines. Annual Average over All Stations. White Perch and Banded Killifish.
White perch continued a long term decline in seine collections with a major decrease in 2003 to
equal the lowest levels since the study began (Figure 169). This was somewhat contradicted by
the LOWESS plot which showed a continued slight increase since the late 1990’s (Figure 170).
Banded killifish was lower than its peak in 2002, but still among the highest values recorded
since the study began (Figure 169). The LOWESS plot suggested that the increase was still
continuing (Figure 171).
