quantify stress-related mortality that may have resulted from stocking. <br />Samples of fish were measured and weighed at the time of stocking and once <br />monthly thereafter to monitor growth and relative condition. Dissolved <br />oxygen, temperature, conductivity, and water clarity of the ponds were <br />measured biweekly. Analysis of water chemistry was performed quarterly by <br />• Grand Junction Laboratories, a certified testing company. <br />In addition to the fish from Willow Beach NFH, a small group of Colorado <br />squawfish was obtained from Jackson NFH, Wyoming. Researchers there had <br />completed their laboratory investigations of .these fish and made those that <br />remained available for our use. The fish were air-freighted to Grand <br />Junction on 20 May. Because of airline error, the fish arrived late and <br />about half were dead; 234 survivors (65-135 mm long) were stocked into a <br />small pond on the Tiara Rado golf course (13th Hole Pond). The pond had a <br />good population of fathead minnows. Once each month, three hauls with a 76 <br />x 2.4-m, 3 x 5-mm-mesh bag seine were used to collect samples for growth <br />measurements and to estimate survival rates. Water temperature was measured <br />at the time of each collection. <br />RESULTS AND DISCUSSION <br />Artificial Spawning Activities <br />We were unsuccessful in our effort to spawn the captive squawfish. Although <br />the male fish began to produce milt and we then injected selected females <br />with carp pituitary, we could only express a small number of eggs from one <br />female. That female died a short while later, as did a male that had also <br />been previously injected. We concluded that the frequent seining and <br />handling of these wild fish necessitated by our procedures had appreciably <br />20
