Objectives:

I. Sort, identify, enumerate, and report on larval fish drift collections

2. Verify species identifications

3, Provide a permanent repository for San Juan River fish collections, field notes, and associated data

4, Assist principal investigators with collection sorting and identifications

Methods:

Larval fish drift collections generated by UNM-NMGF research projects (Colorado pikeminnow drift-netting
study, razorback sucker larval fish survey, Colorado pikeminnow spawning bar larval fish sampling) are
received unsorted and processed as stated above, In addition to recording the length ranges for each species in
each collection, we also note the presence of larval, juvenile, and adult specimens in the samples. The annual
report for the larval fish portion of the study will be prepared by UNM personnel, as it has been since 1995,

We have assisted principal investigators by taking on the responsibility of processing unsorted collections,
Specimens are sorted, identified, counted, measured, catalogued, and data submitted to the principal
investigator for inclusion in reports. In the past;this work has had to be done on relatively short notice.

Samples from projects are received after the principal investigator has completed their work and prepared the
necessary annual report. This means that there will be a lag of one year in reference collection of specimens
and processing of those samples. All collections are matched with the appropriate data-sheet, transferred from
formalin to alcohol, stored in museum quality jars, re-identified, counted, measured (range), labeled, and
catalogued into the permanent MSB Fish Division collection.

Products:

A draft report of the 2001 San Juan River specimen curation and larval fish identification sampling activities
will be prepared and distributed by 31 March 2002 to the San Juan River Biology Committee for review, Upon
receipt of written comments, that report will be finalization and disseminated to members of the San Juan River
Biology Committee I June 2002, Fish collected from this study will be curated in the Division of Fishes,
Museum of South we stem Biology (MSB), Department of Biology, at the University of New Mexico. Original
field notes will be retained in the Division of Fishes and collection information will be electronically stored in a
permanent MSB database program. Electronic copies of the field and collection data will be transferred to the
San Juan River database manager following the successful protocol previously employed.
