Sources of variability and comparability between salmonid stomach contents and isotopic analyses: study design lessons and recommendations Sources of variability and comparability between salmonid stomach contents and isotopic analyses: study design lessons and recommendations
We compared sources of variability and cost in paired stomach content and stable isotope samples from three salmonid species collected in September 2001–2005 and describe the relative information provided by each method in terms of measuring diet overlap and food web study design. Based on diet analyses, diet overlap among brown trout, rainbow trout, and mountain whitefish was high, and...

Stomach emptiness in fishes: Sources of variation and study design implications Stomach emptiness in fishes: Sources of variation and study design implications
This study summarizes fish stomach content data from 369,000 fish from 402 species in 1,096 collections and reports on the percentage of individuals with empty stomachs. The mean percentage of individuals with empty stomachs among all species, locations, habitats, seasons, regions, and collection methods was 26.4%. Mean percentage of individuals with empty stomachs varied significantly...

Piscicides and invertebrates: after 70 years, does anyone really know? Piscicides and invertebrates: after 70 years, does anyone really know?
The piscicides rotenone and antimycin have been used for more than 70 years to manage fish populations by eliminating undesirable fish species. The effects of piscicides on aquatic invertebrate assemblages are considered negligible by some and significant by others. This difference of opinion has created contentious situations and delayed native fish restoration projects. We review the...
