CONCLUSION
The current status of these Colorado River fishes can be
attributed directly to man's activities, primarily alteration
of their habitat. Recovery of these unique fishes now requires
well planned and determined human action. Protection, habitat
preservation and management, research, captive propagation, re-
introduction and public education are all essential components
of a successful recovery program (Jensen, in press). With no
evident recruitment to declining razorback sucker and bonytail
chub populations, the long life spans of these species are
obviously all that have saved them from extinction at this date.
Whether recovery efforts like those being carried out at Dexter
will turn this precarious situation around remains to be seen.
Meanwhile, we are obligated to devote our energies towards
saving those species for which we have a moral and legal respon-
sibility. If we can successfully accomplish even a portion of
the objectives previously outlined, we may be able to preserve
for future generations of Americans some of our most unique
fishery resources.
