<br />Cyprinids and Catostomids from the Prehistoric Hohokam Site of Pueblo Grande in
<br />Phoenix, Arizona / Ciprinidos y catost6midos del sitio prehist6rico Hohokam de Pueblo
<br />Grande en Phoenix, Arizona
<br />KEYWORDS: archaeofauna; prehistoric; Hohokam; Arizona; Cyprinidae; Catostomidae; Gila robusta; Ptychocheilus
<br />lucius; Xyrauchen texanus
<br />ABSTRACT
<br />Analysis of archaeofaunal remains from the major Classic period (A.D. 1100-1450) Hohokam site of Pueblo Grande
<br />near the Salt River in Phoenix, Arizona, indicates that freshwater fish comprised nearly 30% of 10,000 identified animal
<br />bones. Most native minnows and suckers (cyprinids and catostomids) which once inhabited the Salt River were present,
<br />including bonytail chub (Gila elegans), roundtail chub (Gila robusta), Colorado squawfish (Ptychocheilus lucius),
<br />razorback sucker (Xyrauchen texanus), Gila coarse-scaled sucker (Catostomus insignis), flannelmouth sucker (Catostomus
<br />latipinnis), and Gila mountain sucker (Catostomus clarla). These results are the first reported identifications of these taxa
<br />from a prehistoric site near the Salt River in the Phoenix Basin although W. L. Minckley and S. J. Olsen identified them
<br />from an earlier site (A.D. 1 to A.D. 1100), that of Snaketown on the Gila River.
<br />While a few large fish elements were present in the Pueblo Grande assemblage, measurements indicate that nearly
<br />all the fish were small, probably under 250 mm (10 in) in length. In comparison to a few Pre-Classic Hohokam sites,
<br />these data tentatively suggest that a decrease in fish size may have occurred through time, so that by the Classic period
<br />at Pueblo Grande only relatively small fish were available, perhaps as a result of over-exploitation in the vicinity. Fishing
<br />methods employed by the Hohokam which are still a matter of speculation are discussed.
<br />RESUMEN
<br />Analisis de los restos arqueofaunfsticos del sitio Hohokam periodo Clasico mayor (A.D. 1100-1450) cerca del Rio
<br />Salt en Phoenix, Arizona, indican que los peces dulceacuicolas comprendieron cerca del 30 % 10,000 huesos
<br />identificados de animales. Muchos de los de los charalitos y matalotes nativos (ciprfnidos y catost6midos) que una vez
<br />habitaron el Rfo Salt estuvieron presentes, incluyendo al charalito cola dura (Gila elegans) charal cola redonda (Gila
<br />robusta) charal del Colorado (Ptychocheilus lucius), matalote jorobado (Xyrauchen texanus), matalote Sonorense
<br />(Catostomus insignis), matalote (Catostomus latipinnis) y el matalote del desierto (Catostomus clarki). Estos resultados
<br />son el primer reporte de identificaciones de estos taxa para un sitio prehist6rico cerca del Rio Salt en la Cuenca del
<br />Phoenix aunque W.L. Minckley y S.J. Olsen los identificaron para un sitio temprano (A.D. 1 A.D 1100), el de
<br />Snaketown en el Rfo Gila.
<br />Aunque pocos elementos de peces grandes estuvieron presentee en el asamblea de Pueblo Grande, las mediciones
<br />indican que Iasi todos los peces fueron pequeiios, probablemente menores de 250 mm (1 pulgada) de longitud. En
<br />comparaci6n con unos pocos sitios Pre-Clasicos Hohokam, estos datos tentativamente sugieren que una reducci6n del
<br />tamano de los peces ha ocurrido a trav6s del tiempo. Por esto s6lo para el periodo Clasico en Pueblo Grande s6lo peces
<br />pequefios estuvieron disponibles, quizas como resultado de una sobrexplotaci6n en la vecindad. Se discuten los m6todos
<br />de pesca empleados por los Hohokam que son terra de especulaci6n.

<br />Proposal to initiate native fish monitoring committee within Desert Fishes Council /
<br />Propuesta para. iniciar un comit6 de monitoreo de peces nativos dentro del Consejo de Peces
<br />del Desierto
<br />KEYWORDS: monitoring; native fishes; Southwest; population trends
<br />ABSTRACT
<br />I propose creation of the first Desert Fishes Council (DFC) standing committee, a committee to annually monitor
<br />selected southwestern fishes and publish the findings in a new Species Account section of the annual Proceedings. In the
<br />past, DFC Basin Coordinators have reported on a few or all of the species found in a river system, but the monitoring
<br />and data collecting process were informal. Often, the information came by word of mouth from a contractor or as a part
<br />of state or federal monitoring effort, and information was presented orally to the annual meetings and not summarized
<br />in writing. Frequently, species were not monitored at all for several years.
<br />It can be strongly argued that monitoring of threatened, endangered, or species of special concern is not the job
<br />of a private organization like DFC, but instead should be the responsibility of state or federal agencies. Some state and
<br />federal agencies are indeed monitoring these rare fishes, usually on their own lands or portions thereof. However, the
<br />distribution of many species are not bound by state or regional lines (e.g. Colorado River, Virgin River fishes) and
