In the near-term, immediate action to establish appropriate
levels of hatchery stocks of endangered species would be a
high priority item. This is the basic action which would be
_._.
taken to assure the conservation of the species. Each
_ ._
species would be stocked as needed, depending on the results
of ongoing monitoring programs, on the occurrence of events
which could substantially reduce wild populations, and the
need for establishing or augmenting populations. It also
may be necessary, in the near-term period, to limit or
eliminate stocking of non-native game fishes, and, possibly,
to selectively eliminate predatory game fish in parts of the
Upper Basin.
Design and implementation of endangered species monitoring
programs should be a high priority, near-term activity.
Extensive monitoring programs have been conducted since 1979
to meet a variety of objectives. Data from these programs
needs to be analyzed; following that analysis, the programs
need to be reevaluated, and an objective oriented monitoring
program should be implemented which supports recovery of the
endangered species. Monitoring would continue through the
intermediate and equlibrium periods.
During the near-term, a variety of research projects and
,.
feasibility analyses should be initiated to provide
~- information necessary to assure that all endangered fish
4'y management activities conducted by the Federal government
_.....~.... w ,_ ,
~~,'~ and the States contribute directly and effectively to the
recovery of the species. Scientifically based criteria for
delisting would be established.
Intermediate activities include maintenance of hatchery
stocks and stocking, continued control of predators as
needed, data evaluation and continued monitoring,
