The video showcases fish sampling in the Colorado River Basin, focusing on roundtail chub (Gila robusta) while also encountering invasive crayfish and juvenile mottled sculpin. Essential gear includes scales, pit tag readers, and data books for species codes and electrical settings. Using a barge, the team captures fish of various sizes, proving its effectiveness in diverse habitats. Organization is key—only essential staff stay near the barge to ensure accurate measurements and tagging. Recorded effort times later help calculate catch per unit effort and other metrics, highlighting the balance between precise fieldwork and efficient data management.
