Box 7. Guidelines for preparation of a stocking plan for release of captive
-reared endangered fishes into the Upper Colorado River Basin.
1. Define objectives for stocking endangered fishes and relation of the
objectives to the Program Recovery Action Plan.
2. Identify alternative management options that could achieve the same
objectives and discuss why stocking was selected over these options.
3. Provide justification of stock selected for the stocking effort
(i.e., broodstock developed from a wild stock inhabiting the river
reach to be stocked or nearest neighbor).
4. Provide the criteria (e.g., geographic distribution and abundance,
identified spawning sites, migrations, known movement and interchange
between stocks, and data from genetic surveys) used for identification
and characterization of the captive endangered fish stock to be used
in the stocking effort.
5. Describe the status and trends of the target endangered fish stock
including biological, demographic, environmental, and ecological data
for that specific stock.
6. Describe the breeding strategy used to maintain genetic diversity in
the captive-reared fish that is similar to the wild stock used as
founders.
7. Describe the stocking location including the available habitat by life
stage of the endangered fish species.
8. Provide rationale for the size of fish to be stocked and the mark or
tag used to identify stocked fish if recaptured.
9. Provide rationale for the numbers of fish to be stocked.
10. Describe the timing of stocking including frequency if repeated
stocking is planned.
11. Discuss the likelihood of success as well as genetic risks to the
target stock and risks to other endemic fish species in the
ecosystem.
12. Describe methods for systematic monitoring, evaluation, and reporting
of the stocking effort.
