PREFACE 0.
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 Mountain/Prairie Region (R-6). 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.mintroduction
or augmentation; (4) management of nonnative species and sport fishing; and
(5) research, monitoring, and data management (U.S. Fish and Wild]-ife 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, research and
monitoring.
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 diagnosis 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, choice of
treatment may vary depending on the diagnosis; degree of
intervention that is required; availability of qualified
personnel, equipment, and facilities; cost and duration
of treatment; and expected outcome. The desired outcome
is evaluated in terms of probability of success against
potential risks or complications. The physician and the
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, patient is considered
cured and discharged. However even after discharge, the
patient 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 this medical model.
