PREFACE Almost 5 years have passed since the publication of the first revision of this report on the status of catfish nutrition and feeding. During that time, several studies have been completed that impact both feed formulation and feeding practices. These new data have been included in the report. Much of the information presented remains unchanged. As in the original report, certain sections are presented in more detail and are more technical than others. We hope the information presented herein is practical and is presented in a usable manner. As stated in the original report, the information presented is intended as a guide because the feeding of catfish, though based on sound scientific evidence, remains in part an “art” as much as a science. ACKNOWLEDGMENTS The authors appreciate the support of the Mississippi Agricultural and Forestry Experiment Station, Delta Branch Experiment Station (DBES), and Thad Cochran National Warmwater Aquaculture Center (NWAC) for funding for this bulletin. We want to offer a special thanks to Brian Bosworth, Terry Hanson, and Jeff Terhune for critical review of the manuscript.
