Topic Fish: Leidy Native Fishes Index for Sonoma County Sites
 
Caption:  This chart shows the index of native fish composition in samples by Rob Leidy for Sonoma County streams 1992-1998. Index describes the percentage of sample consisting of native species by abundance (1-3 scale, where 0 = no native fishes, 1 = 1-33% of the total number of individuals collected were native, 2 = 34-66% of the total number of individuals collected were native; and 3 = 67-100% of the total number of individuals collected were native). Null scores for one Calabazas Creek site and Stuart Canyon Creek are the result of no fish collected. Sample sites were at least 30 meters in length and represented multiple habitat types. Surveys typically used block nets and electrofishing. See Info Links for more information.
