<br /> <br />Status: <br /> <br />· Table 2 identifies the species, numbers, and sizes of fish stocked during 2003 <br />into various river reaches to meet requirements of the integrated stocking plan <br />and research needs for the Recovery Program. <br /> <br />· The Recovery Program has moved to a tiew passive integrated transponder <br />(PIT) tag with a lower frequency for stocked fish beginning in 2004. <br /> <br />Table 2.-Species, numbers, and sizes of fish stocked during FY03 to meet the integrated <br />stocking plan and research needs. <br /> <br /> <br />Species <br /> <br />River Section <br /> <br />Number, Season (Hatchery) <br /> <br />3,501; Summer-Fall (Wahweap) <br />> 250,000, Spring (Dexter) <br />10,000, Spring (Wahweap) <br /> <br />3,043, Summer-Fall (Wahweap) <br /> <br />885, Spring (Mumma) <br /> <br />6,303, Summer-Fall (Wahweap) <br /> <br />8,619, Summer-Fall (Ouray) . <br />345,000, Spring (Ouray/Grand Junction) <br /> <br />2,364, Summer-Fall (Grand Junction) <br /> <br />5,358, Summer-Fall (Grand Junction) <br /> <br />1,000, Summer-Fall (Grand Junction) <br /> <br />1,051, Summer-Fall (Grand Junction). <br /> <br />Bonytail <br /> <br />Green (Middle) <br /> <br /> <br />Green (Lower) <br />Colorado (Colorado) <br />Colorado (Utah) <br />Green (Middle) <br /> <br />Razorback sucker <br /> <br />Green (Lower) <br />Colorado (Colorado) <br />Colorado pikeminnow Colorado (Colorado) <br /> <br />Gunnison <br /> <br />v. <br /> <br /> <br /> <br />Size (inches) <br /> <br />-6 <br />larvae <br />juveniles <br /> <br />-6 <br /> <br /> <br />>8 <br /> <br />-6 <br /> <br />-10 <br />larvae <br /> <br />> 12 <br /> <br />> 12 <br /> <br />>6 <br /> <br />>6 <br /> <br /> <br /> <br />Goal: To support recovery activity, monitor endangered fish status and trends, and <br />maintain Recovery Program data archives. . <br /> <br />· Mark-recapture popul~tion estimates are underway to determine progress <br />toward achieving the recovery goals. Monitoring in 2003 was the last year in a <br />4-year sampling effort to obtain. population estimates for Colorado . <br />pikeminnow in the middle Green River and an expanded 3-year sampling effort <br />for Colorado pikeminnow in the lower Green River. A draft report on these <br />annual population estimates is due in March 2004,.. A3-yearsampling effort <br />for annual Colorado pikeminnow population estimates in the Colorado River <br />was initiated in 2003 (initial results continue to show an increase in this <br />population). The current sampling schedule for Colorado pikeminnow <br />populations is samplingJor 3years consecutively followed by 2 years of no <br />sampling to minimize sampling impacts. <br /> <br /> <br /> <br />Status: <br /> <br />8 <br /> <br /> <br /> <br /> <br />
