DOCUMENT ID: [I.D. 120103E]
SUBJECT CATEGORY: Endangered Species; File No. 1375
DOCUMENT SUMMARY: Notice is hereby given that Dr. Thomas J. Kwak, U.S. Geological Survey, North Carolina Cooperative Fish and Wildlife Research Unit, Box 7617, 201 David Clark Labs, North Carolina State University, Raleigh, North Carolina 276957617, has requested a modification to scientific research permit no. 1375.
SUMMARY: Scientific research,
Permit No. 1375 authorized the permit holder to deploy 1,000
hatcheryreared juvenile shortnose sturgeon (Acipenser brevirostrum) in
cages at 10 test sites within the Roanoke/Albemarle River system for 28
days. The fish were then supposed to be euthanized and their tissue analyzed for contaminants.
[[Page 69389]]
The results of this study would have provided needed information to
determine if water quality is a limiting factor of the ecological
success of shortnose sturgeon in this river system. When the initial
study was conducted, however, high water temperatures and low dissolved
oxygen contributed to a shortened experiment time. Although the results
obtained were useful, the permit holder wants to repeat the experiment
and requests authorization to obtain an additional 1000 fish for that purpose.
