habitat requirements and limiting factors of humpback chub. Therefore, we
recommend beginning the former three tasks in the second or third year of
the program. Also, for funding purposes, it appears to us that Tasks 12
aad 22 could be carried out as a single project.
Task 4, Determine taxonomy of Gila at various life stages, appears esseati,
to carrying out the humpback chub restocking objectives. We anticipate th~
L-2 National Park Service funds ($5,000) will be available to begin this study
in FY 1979. It is assumed the study will be a single study through the Pi.
