Recovery, by definition, implies that reestablished stocks will become
self-sustaining. Genetics management goals were identified to meet the
philosophy in maintaining the genetic diversity of endangered and
candidate fishes (See Box 1).
C. Genetic Conservation . Genetic conservation of endangered and candidate
fishes will be accomplished through three separate management documents:
Genetics Management Guidelines. The guidelines provide the
conceptual framework of genetics management and rationale that will
be employed to maintain genetic diversity of endangered and candidate
fish. These guidelines will (1) provide criteria for identification
and characterization of stocks and for determining the status and
trends of these stocks. (2) provide protocol for conserving the
Box 1. Philosophy, and goals of the recovery/restoration program
for genetics management of endangered and candidate fishes.
PHILOSOPHY
To maintain the genetic integrity of wild and captive-reared endangered
and candidate fishes to prevent irreversible losses of genetic diversity
that may result from management interventions or lack of action.
GENETICS MANAGEMENT GOALS
To prevent immediate extinction of any endangered or candidate fish
stocks.
2. To conserve genetic diversity of wild fish stocks so as to
protect or restore viable wild stocks by removing or significantly
reducing limiting factors that caused population declines.
3. To maintain genetic diversity in captive-reared endangered and
candidate broodstocks similar to that of wild stocks used as founders.
genetic variability in wild stocks. (3) define the need for captive-
reared fish, (4) identify genetic risks associated with captive
propagation. (5) provide breeding strategies for captive propagation,
6) how to chouse founders for broodstock development, (7) describe
how to estimate the number of fish required to produce broodstocks.
