3 native and 3 introduced fish species (Table 2). All squawfish <br />appeared in excellent health but later stomach analysis indicated <br />a complete absence of food items (P.C. Marsh, pers. comm.). <br />Possible explanations for this observation are that fish either <br />regurgitated stomach contents at time of capture or were in the <br />nets long enough to allow complete digestion of stomach <br />contents. All seven squawfish were either dead or dying at the <br />time nets were run despite the use of trammel nets designed to <br />keep netted fish alive. <br />Seining in September and a later trip by Arizona State <br />University (ASU) personnel in November failed to collect any <br />additional Colorado squawfish. In January 19$6 another survey <br />effort by ASU personnel collected an additional five large <br />Colorado squawfish (x TL 362 t 34 mm, 333-412; x WT 314 t lU3 g, <br />218-462; P. C. Marsh, pers. comm.). As with those collected in <br />September 1985 all stomachs were empty but the presence of <br />visceral fat and overall condition of the captured fish indicated <br />that feeding by squawfish was evident. Unlike September 1985 <br />collections, all squawfish were alive in the nets when run. <br />Additionally, Bill Silvey (AGFD) received an unverified fisherman <br />report of a squawfish caught at Perkinsville in November 1985. <br />Discussion <br />Re-establishment of the Colorado squawfish in_the lower <br />Colorado River basin is uncertain but appears attainable if <br />existing riverine conditions are maintained and proper recovery <br />,, <br />protocol is conducted.
