<br />San Juan River Specimen Curatlon And Larval Fish Identification <br />Fiscal Year 2001 Project Proposal <br /> <br />Principal Investigators: Steven P, Platania and Alexandra M. Snyder <br />Division of Fishes - Museum of Southwestern Biology <br />University of New Mexico <br />Albuquerque,~ 87131 <br />(505) 277-6005 <br />platania@unm.edu amsnyder@urun.edu <br /> <br />Backl!:round: <br /> <br />Personnel from the Division of Fishes, Museum of Southwestern Biology (MSB), at the University of New <br />Mexico are responsible for two inter-related programs on the San Juan River, The Fish Division is the <br />repository for specimens collected and retained by researchers. Fish taken under these programs are initially <br />sorted by the principal investigator, held until they have submitted their yearly-progress report, and then <br />received by MSB personnel. The collection is accessioned, specimens transferred from formalin to alcohol, <br />identifications verified, individuals enumerated, length ranges recorded (largest and smallest specimen in a <br />collection), collection data verified and transferred to wet labels, and incorporated into a database. Changes in <br />species identifications are noted and returned to the principal investigator along with the entire data set (listing <br />of collection locality, collectors, date, original field number, species, nwnber of specimens, length ranges, and <br />museum catalog number), In addition to performing duties associated with collections curation, we are also <br />responsible for complete processing (sorting, identifying, counting, curating, and reporting) of selected San <br />Juan River collections (larvaJ drift netting samples, razorback sucker larval fish sampling, spawning bar fish <br />collections). The samples (almost 600) generated by the aforementioned three studies resulted in the collection <br />of over 20,000 larval fish during 1998 (this is an estimate as all samples have not been processed - at present we <br />have sorted and identified over 15,000 larval fish). <br /> <br />In 1998, we processed almost 50,000 larval and juvenile fishes collected by the Utah Division of Wildlife <br />Resources (during 1996) and University of New Mexico-N.M. Game and Fish researchers (during 1997). The <br />1998-99 Utah Division of Wildlife Resources and New Mexico Department of Game and Fish low-velocity <br />habitat samples will be processed beginning in the summer 2001. As in the past, deviations in the <br />identifications of those samples will be noted and forwarded to the principal investigators. <br /> <br />Studv Area: <br /> <br />This projcct does not involve the collection of specimens but instead the processing and curation of samples <br />gathered by the different research components of the San Juan River Research program. The collective <br />sampling area for other researchers will be the San Juan River between Farmington and the Clay Hills boat <br />landing (RM 2.9) just above Lake Powell in Utah. <br /> <br />17 <br /> <br />c-: <br />
