Mule deer is released after being radio-collared. The tracking information from this collar will enable researchers and managers to track the migrations of mule deer and evaluate their habitat and population performance and will aid in management of mule deer populations in Wyoming.

The pallid sturgeon is an endangered riverine sturgeon with historical distribution restricted to parts of the Yellowstone, Missouri, Mississippi, and Atchafalaya Rivers. Although rare, pallid sturgeon in the lower Mississippi River appear to be naturally recruiting, and information about habitat use is important to conserve this species.

The Bureau of Reclamation (USBR) initiated a study on how its water operations influence fishes in the Missouri River basin above Fort Peck Reservoir. Of utmost concern is the effect of these operations on the spawning success and recruitment of endangered pallid sturgeon.

This project is designed to assess the feasibility of "rescuing" specific genetic lineages of bull trout from likely extirpation in three imperiled major lake drainages in GNP, through translocation of drainage-specific stocks into lakes located above barrier falls within parental drainages.

Ungulate migration is one of the world’s most awe-inspiring animal behaviors, and it has important ecological benefits for the migrating species, as well as cascading effects throughout terrestrial food webs. Yet, ungulate migrations have been declining globally due to factors such as anthropogenic disturbances and environmental change.

Masters student Lila Warren documented that muskellunge in her study rivers were reproducing all by themselves and hatchery fish, in all likelihood, do not need to be stocked to sustain the fishery.

Biologists in North America have been studying the effectiveness of fish stocking programs ever since fish were artificially spawned, reared, and stocked in the late 1800s.

Research of the Montana Cooperative Fishery Research Unit will continue to focus on applied fisheries-management problems and issues. Our studies are initiated in response to the needs of the Cooperators and other management agencies and are designed to provide information useful in directly improving management of aquatic resources.
