Description of Work To achieve a better understanding of seasonal habitats and migratory behaviors of Asian carp, we will conduct studies using telemetry, sonar and conventional fish sampling to determine 1) if, when, and where Asian carp congregate, 2) habitat overlap between Asian carp and native fishes, especially native filter-feeding fishes and potential predators, and 3) the suitability of large rivers and tributaries for spawning by Asian carp. We will also assess feeding behaviors by sampling food particles from areas with telemetry-tagged fish, at random sites and in Asian carp stomachs. Food from these sources will be characterized with a particle analyzer, genetics and microscopy to determine preferences and limitations [...]
