the Colorado River and its tributaries, which may vary their exposure to various stresses, the
adults in this study were held in specific locations as part of an exposure to selenium and other
inorganic elements. After exposure, adults were hand spawned in late spring when water
temperatures reached a level associated with naturally spawning of razorback sucker. Following
spawning, tests were conducted with eggs and larvae.

Objective

The objective of this research was to conduct partial life cycle studies to determine if
environmental exposure of adult razorback sucker to selenium and other inorganic elements in
flooded bottomland sites affects their survival, growth, and reproductive success.
