J. W. Mumma Native Aquatic Soecies Restoration Facilitv There are currently Arkansas darter, bonytail, boreal toads, common shiner, Northern redbelly dace, plains minnow, Colorado pikeminnow. Rio Grande chub, Rio Grande sucker, roundtail chub, Southern redbelly dace, and suckermouth minnow on the unit. Seven fish species were spawned and reared on the unit in 2003, comprising over 76,000 fish released into Colorado waters, more than doubling 2002 production of these species. All seven of these species have spawned again this spring. An eighth species, the suckermouth minnow, has been successfully spawned and reared this spring for the first time at the facility. Colorado pikeminnow and bony tail are on the unit for grow-out purposes only as broodstock is maintained at federal facilities. Approximately 20,000 bonytaiI are on the unit. This spring, 2,587 8" fish were stocked in the Colorado River. An additional 2,500 bony tail will be released into the Green River this fall. Nearly 20,000 bonytail have been released into Colorado waters since the unit began stocking bony tail in 2002. Approximately 9,000 Colorado pikeminnow are currently on the unit. 2,3607" fish were released into the Colorado and Gunnison Rivers in May and June. 1,280 more Colorado pikeminnow will be released to the San Juan recovery program in mid June. Over 4,600 Colorado pikeminnow have been released since the unit began stocking in 2003. The last of the razorback suckers on the unit, approximately 575, were released to grow out ponds in spring of2003. Razorback sucker production has shifted to other units and the Native Species Hatchery will focus production on Colorado pikeminnow and bonytail for the Colorado River recovery programs. Due to severe drought conditions, roundtail chubs from the La Plata River and Arkansas darter from Big Sandy Creek were salvaged and brought into the hatchery last fall. Both populations have successfully spawned this Spring and progeny will be returned to those waters and nearby tributaries pending water conditions. There are approximately 560 boreal toads on station from 20 different breeding sites around the state. Over 14,000 tadpoles and toadlcts were released on thc Grand Mesa in summer 2003 for reintroduction studies. The facility successfully bred 8 pairs of toads in April and May 2004 and will continue rearing wild tadpoles and toadlets for the Grand Mesa study. Tadpoles and toads were also supplied to research facilities to further the study of chytrid fungus. More release sites are being evaluated for the presence of chytrid fungus in preparation for additional releases in the next few years. The USFWS will make a listing decision by 2005.
