changes in populations, both domestic and wild. Standard
quantitative biological surveys would be performed annually in the
spring and early summer during high flows to assess the survival and
distribution of stocked razorback sucker. Reproductive condition
and sex ratios would also be recorded. Electrofishing and
entanglement nets would be used to accomplish this task. Seine
surveys would be performed annually following spawning to
investigate for the presence of razorback sucker larvae and young-
of-the-year fish. Electrofishing and netting would be used in
subsequent years to search for juveniles or young adults that would
verify that recruitment is occurring.
