ABSTRACTS OF PRESENTATIONS IN ORDER PRESENTED <br />RESUMEN <br />El Departamento de Parques y Vida Silvestre de Texas estA actualmente involucrado en tres proyectos relevantes <br />para los intereses del Consejo de Jos Peces del Desierto, el Reconocimiento del Rio Grande, Proyecto Cienaga Balmorhea <br />y el Reconocimiento de la Situaci6n Actual de los Peces del Desierto Chihuahuense. Los reconocimientos del Rio Grande <br />buscan desarrollar una comprensiva base de datos de comunidades de peces para. las ecoregiones relativamente no <br />impactadas del rio en Texas. Los datos seran usados como base para. el manejo del recurso proveer la protecci6n y <br />mitigaci6n despues de la implementaci6n del Tratado de Libre Comercio en Norteam6rica. El Proyecto Cienaga <br />Balmorhea invotucra la construccion de una. cienaga des6rtica funcional que no s61o sirve como un refugio adicional para <br />dos peces en peligro, pero tambi6n cream un ejemplo de un ecosistema en extinci6n en una escena educacional que esta <br />desponible para el pdblico en general. El Reconocimiento de ]a Situaci6n Actual de los Peces del Desierto Chihuahuense <br />es un proyecto cooperativo de la Secci6n 6 que proveeru la determinaci6n de la situaci6n actual de varias especies de <br />peces con Categoria Federal 2 que ocurren en la del Desierto Chihuahuense de Texas, Nuevo Mexico y la Republica de <br />M6xico. <br />DIVINE, G. (U.S. Fish and Wildlife Service, Office of Endangered Species, Albuquerque, NK <br />Agency Report - U.S. Fish and Wildlife Service, Region 2, Albuquerque, New Mexico <br />KEYWORDS: <br />ABSTRACT <br />Efforts to conserve the native fish fauna of the and southwestern United States and northern Mexico must continue <br />if these species are to survive through time. During the reporting period one species was proposed for listing with <br />designation of critical habitat proposed also. Designation of critical habitat is being proposed for two species listed <br />previously. Recovery plans were approved for two species. The number of Freedom of Information Act Requests and <br />scope of information requested has increase substantially as has the number of Section 7 consultation actions. These <br />activities led to a very busy year. <br />A very busy year since we last met. Activities are grouped under three categories. They follow: <br />1. Prelicting/listing <br />A package proposing to list the Rio Grande minnow (Hybognathus amarus) as endangered with critical habitat has <br />been completed. Publication of the proposed rule will occur during fiscal year 1993. <br />Proposed critical habitat for the spikedace (Meda fulgida) and loath minnow (Tiaroga cobitis). Due to concerns <br />over the amount of time that has elapsed since the 1986 original proposal to designate critical habitat for these two <br />species, the Service has decided to repropose the designation of critical habitat. A new economic analysis has been <br />prepared. Publication of the proposal is scheduled to appear in the Federal Register during fiscal year 1993. <br />Proposed upgrading status of spikedace and loath minnow from threatened to endangered. Threats to these two <br />species have increased dramatically thus the need for greater protection. <br />A proposed rule to list the Pecos pupfish (Cyprinodon pecosensis) as an endangered species with critical habitat has <br />been prepared. This action is scheduled to be completed during Fiscal Year 1993. <br />2. Recovery <br />a) Plans <br />Recovery plans have been completed for the Pecos bluntnose shiner (Notropis simus pecosensis) and Sonora chub <br />(Gila ditaenia). Both plans were approved September 30, 1992. <br />The recovery plan for the Gila trout (Oncorhynchus gilae) has been revised. Approval of the revised plan is <br />anticipated during fiscal 1993. <br />Draft recovery plans have been completed for the beautiful shiner (Cyp7lnella formosa), desert pupfish (Cyprinodon <br />macularius), Yaqui catfish (Ictalurus pricet), Yaqui chub (Gila purpurea) and Yaqui topminnow (Poeciliopsis occidentalis <br />sonwiensis). Approved plans are anticipated for all five species by September 30, 1993. <br />On January 23, 1992, Region 2 issued a Guidance and Procedures Memorandum designed to ensure approved <br />recovery plan are prepared for all 107 federally listed species for which Region 2 has lead. All plans are to be completed <br />prior to September 30, 1994. <br />b) Actions. <br />Construction of a refugium at Phantom Lake Spring, Texas, is underway. The Bureau of Reclamation and Texas <br />Parks and Wildlife Department are primarily responsible for the construction of this facility. Both the Comanche Springs <br />pupfish (Cyprinodon elegans) and Pecos gambusia (Gambusia nobilis) will be provided additional habitat. <br />A 5-year study is underway on the Pecos River. The purpose of this study is to gather information on a variety of <br />flow releases from mainstem reservoirs and how different flows impact the Pecos bluntnose shiner and its habitat. <br />A 7-year research study is being finalized for the San Juan River. Sampling efforts during 1992 took 4 (one a <br />recapture) adult Colorado squawfish (Ptychocheilus lucius). Young-of-the-year squawfish were not captured in New <br />Mexico during 1992. Telemetry studies on tagged adult squawfish continue in the San Juan. <br />4
