ACKNOWLEDGEMENTS

Interlibrary Loan and Science-Reference
Deparbnents of Colorado State University Libraries
and S. A. Johnson were invaluable in locating and
obtaining much of the literature for this review. U.S.
Fish and Wildlife Service Office of Information
Transfer and Fish and Wildlife Reference Service
also assisted with literary searches. G. A. Goodchild
loaned copies of difficult-to-obtain literature and
provided a computer file of references in the
Burridge et aI. (1990) bibliography. The latter
expedited entry of much electrofishing literature in a
bibliographic database under Reference Manager, a
program provided by Research Infonnation Systems
Inc. S. A. Johnson also helped prepare the indexed
bibliography included in this report as Appendix I.
A request for infonnation on effects of
electrofishing was published in Fisheries by the
American Fisheries Society and printed in various
other fishery newsletters and bulletins. A survey of
electrofishing experiences, observations, and
recommendations was also distributed to Colorado
River Basin Researchers and fishery faculty and
graduate students at Colorado State University. In
response, many researchers provided copies of
unpublished manuscripts and reports and conveyed
their experiences, observations, and concerns. The
more pertinent of this unpublished infonnation is
included, with pennission, in this review.
Many others contributed infonnation and
materials for this report. M. Yard provided a
preliminary assessment of the problem, a list of
questions to be addressed, and an initial list of
references. N. G. Sharber was especially helpful in

interpreting some the literature, clarifying pertinent
electrical concepts, and conveying his ideas
conceming the nature of fish responses in electrical
fields. C. L. Bjork prepared the diagram for Figure
10. Photographs were provided by M. S. Quinton
for Figure 2, G. Oliver for Figure 3, W. A.
Fredenberg for Figures 4 and 15, and N. G. Sharber
for Figures 13 and 14. Photographs for Figures 1
and 16 were reproduced with pennission from
Sharber and Carothers (1988). Diagrams for Figures
7 and 8 were photocopied from Novotny (1990) and
Sternin et aI. (1972, 1976), respectively. Table 4
was photocopied with pennission from Reynolds
(unpubl. ms. 1992). Appendices III and IV were
photocopied from Stemin et aI. (1972, 1976), and
Appendix V from U.S. Fish and Wildlife Service
(1985).
L. W. Crist, W. A. Fredenberg, 1. A. Hawkins,
D. L. Horak, C. W. Meyer, 1. B. Reynolds, N. G.
Sharber, and M. B. Snyder reviewed various drafts of
the report. K. RBestgen and R T. Muth also
reviewed portions of the manuscript. Reviewers'
suggestions were invaluable for correcting
misunderstandings, errors, and grammar, and for
making the text clearer and more readable.
This investigation was sponsored by the Glen
Canyon Ecological Studies Project and Upper
Colorado Regional Office of the Bureau of
Reclamation, U.S. Deparbnent of the Interior. The
support, assistance, and patience of D. Wegner, R
Williams, L. W. Crist, K. R Bestgen, and R T.
Muth are appreciated.
