dc.description.abstractSeven adult Guadalupe bass from Lake Travis, Texas, were tagged with ultrasonic transmitters and tracked intermittently over a one-year period. Seven additional Guadalupe bass provided data on post-release and pre-mortality behaviors. Many activity patterns of the tagged bass changed significantly as the fish progressed through a post-operative recovery period, into a "healthy" period, and then into a pre-mortality period. Differences were found in l:xxiy temperatures, amounts of apparent feeding, home-range and nomadic activity, pelagic activity, relationships to habitat and cover types, and nervous responses. Each of the variables analyzed was associated with a unique recovery and pre-mortality profile. The data suggested that the assumption of behavioral normality for electronically-tagged lack basses should not be made without a statistical analysis of changes in behavior as specimens progress through a recovery-mortality ty sequence. The data also indicated that many behaviors of the healthiest tagged Guadalupe bass were significantly different £ran those of wild Guadalupe and largermouth basses. Detailed remarks concerning both electronic tracking and scuba diving as data-collection techniques are included, as well as descriptions of the behaviors of individual Guadalupe bass. A review of the extant literature on the Guadalupe bass is appended.
