Implications Of Channel Catfish Movement In An Internationally Managed System, Henry Hansen

School of Natural Resources: Dissertations, Theses, and Student Research

The large-scale movements and spatial behavior of channel catfish in the Red River of the North, have direct interactions with geopolitics, anthropogenic structures, and ecosystems. Investigating the spatial dynamics and exploitation of this mobile and internationally managed fish species provides opportunities for resource managers to design evidence­-based policy for the diverse interest groups that utilize the fishery. My thesis comprised two parts: 1) characterize system­wide movement and survival patterns using mark­-recapture methods and acoustic telemetry and 2) project the interaction of hypothetical exploitation scenarios and alternative movement methodologies to assess the fishery from an ecosystem service flow perspective.
