     COURSE OBJECTIVE:  To provide an introduction to basic
     biostatistical and sampling design concepts relative to common
     analytical problems for aquatic resource monitoring and applied
     research issues.  The emphasis will be on applications to types of
     fish population and angler sampling techniques frequently used by
     state biologists.
