• Reintroduction Plans and other planning documents should be prepared well in
advance of projected field or laboratory studies. This is especially important if
large or mature fishes are needed for the studies. For example, approximately
five years are needed to produce mature bonytail, humpback chubs,and bull trout,
seven years to produce adult razorback suckers and Colorado squawfish, and pallid
sturgeon may require in excess of eight years.
B. Procedures for Disposition of Captive-Reared Fish. Production targets are based
on the numbers of fish that were identified for specific program needs. Under
normal operating procedures, unfit fish (e.g., hybrids, deformed, those with
contagious diseases, etc.) will be euthanized following accepted protocol of the
fisheries profession. Fish that are no longer needed for specific purposes will
be identified for disposal. Disposition of such fish will be done by priority:
1. Captive-reared fish will be used to meet approved program needs for refugia,
broodstock development, laboratory and field experiments, and reintroduction
and/or augmentation plans.
2. Provide fish for other research studies.
3. Provide fish to other agencies for use in research, augmentation or
restoration.
4. Provide fish for information and education programs.
5. Maintain fish for possible future use if space is available and the cost is
• not prohibitive.
6. Provide specimens for reference fish collections in museums, colleges, or
universities.
7. Fish not identified in Items 1 through 6 will be euthanized following the
accepted protocol of the fisheries profession.
C. Euthanasia Protocol. Euthanasia of excess fish will follow recommendations in the
"Guidelines for Use of Fishes in Field Research". These guidelines were developed
jointly by the American Fisheries Society, American Society of Ichthyologists and
Herpetologists, and the American Institute of Fisheries Research Biologists.
D. Permit Requirements. All Actions involving the disposition of captive-reared fish
must be covered by appropriate Federal and State permits. Contact the appropriate
U.S. Fish and Wildlife Service, Ecological Service State Supervisor or the
Endangered Species Chief in the Denver Regional Office.
