Every year, tens of thousands of Razorback Sucker larval fish are collected from Lake Mohave by Bureau of Reclamation, National Park Service, Fish and Wildlife Service, Marsh and Associates, Nevada Department of Wildlife, and Arizona Game and Fish Department. Although these fish still spawn naturally in the lake, the presence of large non-native predators in the lake such as Striped Bass results in little to no natural recruitment.

The larvae are collected using a light to attract prey and therefore the suckers, then they are pulled out of the water using a fine mesh aquarium net. The larvae are 10-20 mm long with a transparent body and darkly pigmented eyes. After capture they are placed in a 5-gallon bucket with water and transported to the Lake Mead and Willow Beach fish hatcheries. These fish are raised at the hatcheries for several years until they are larger than 350 mm, a size that had been determined optimum for fish survival. They are then stocked throughout the lower Colorado River Basin.
