(e.g., length, weight, scales for ageing, and possibly tagging)
for better evaluation of long-term survival, mortality,
movements, growth, age structure.
The research would permit a better evaluation of the impact of
different water years and combinations of flows on the survival
of young fish to adult stocks.
Deliverables:
UDWR and LFL will jointly submit an annual report at the end of
the fiscal year

Hypothesis Testing Studies
Task 6. Movements and habitat use of channel catfish and carp in
the upper Green River basin.
Description of work:
An ongoing Hypothesis Testing project under the lead of the FIATS.
FY 1992 work will conclude the 1991 study including exploring
behavior of channel catfish and carp during the winter/spring
period in the Green and Yampa Rivers and their relationship to
endangered fish spawning success.
Field work would involve the capture and radio implantation of
carp and channel catfish in Dinosaur National Monument. Fish
would be tracked to determine seasonal use of the Green and
Yampa Rivers
An analysis of winter and spring flow events in the Green and
Yampa rivers relative to fish movements would be conducted to
determine if flow recommendations can be made that would aid in
control of non-native fish populations.
