PREFACE
These "Genetics Management Guidelines" provide a conceptual framework of
genetics management and rationale for maintaining the genetic diversity of
listed and candidate fish stocks within Region 6 Mountain/Prairie Region.
These guidelines are intended to serve as a practical reference document.
Boxes are used to highlight important parts of these guidelines. A glossary
of terms used is provided in Appendix 1. A review of genetic concepts,
principles, and issues related to fisheries management are included as
summarized by Kapuscinski and Jacobson (1987).
The Upper Colorado River Endangered Fish Program (Program) has been used as a
model for this umbrella document. The Program consists of five elements for
recovery of endangered fishes within the Basin: (1) provision of in-stream
flows; (2) habitat development and maintenance: (3) native fish
reintroduction/augmentation; (4) management of nonnative species and sport
fishing: and (5) research, monitoring, and data management (U.S. Fish and
Wildlife Service 1987a, 1987b, 1993). Genetics management of endangered
fishes is an integral part of an overall program which involves habitat
development and maintenance, management of wild fish populations, native fish
reintroduction, and research/monitoring efforts.
The conceptual framework for planning, implementing, and evaluating management
actions for genetics management of endangered and candidate fish can be
compared with an adaptive management medical model:
A physician reviews the patient's medical history,
interviews and then examines the patient to determine
the origin and nature of the disease or discomfort.
Following the assessment of the patient's medical status
and identification of the problem, the physician
provides a prognosis of the problem based on the data
and the physician's knowledge and experience. The
course of action depends upon whether the problem can be
treated. If the problem can be treated, the choice of
treatment may vary depending on the diagnosis, degree of
intervention that is required, the availability of
qualified personnel, equipment, and facilities, cost and
duration of the treatment, and the expected outcome.
The desired outcome is evaluated in terms of probability
of success against potential risks or complications.
The physician and patient select a treatment plan. . The
patient is then monitored and treatments may be
continued, modified, or stopped based upon the response
of the patient. If the treatment is fully successful,
the patient is considered cured and discharged. However
even after discharge, the patients may be routinely
monitored. The systems approach to genetic management of
fish species in this document is parallel to the
adaptive management approach described in the medical
model.
