Pallid sturgeon were found to prefer wider river channels, midchannel sandbars, and numerous islands, and were most commonly recorded in water depths between 2 and 47 feet (0.61 and 14.33 m). The study also showed that the pallid sturgeon moved as much as 13 miles (21 km) per day and up to 5.7 miles per hour (9.2 km/h). [32]
