PREFACE
THE USE OF FISHES Hs experimental animals has contributed much to our knowledge in many phases of
animal science. NigrelH ( 1953 ) has reviewed some of
the more outstanding of these contributions. The principal obstacle connected with the use of fishes as experimental animals is the lack of information on the
selection and maintenance of experimental fishes. This
apparent need has prompted the author to attempt to
bring together some of the more important considerations associated with this problem. Notable among these
considerations are nutrition, disease, and the artificial
maintenance of suitable environmental conditions.
This work is limited to a treatment of freshwater
fishes and is based upon the author s experience in this
area of interest and upon such Hterature as seems
relevant. There are some considerations concerning the
maintenance of captive fishes about which there is
little information available. It is hoped that research
persons wiU. be stimulated to make contributions on
these topics.
The author wishes to thank his v^dfe, Sue D. Lewis,
and Mr. Vernon Cole and Mr. Robert Summerfelt of
the Southern Illinois University Fisheries Research
Laboratory for contributing to this work.
