Unlimited to facilitate a "hatchery box" for cutthroat trout production. Trout eggs ~ placed in the box will hatch and passively enter the outflow channel. Habitat in the channel will hopefully sustain the young larvae until they are ready to enter ~ the Green River. All work was completed by June, 1997 and the pond was in full ~ operation. The wetlands are an integral part of the City's Greenest concept that • includes trails, and public open space linking to the existing Scott's Bottom Nature Area and historic Expedition Island. ~ Col. River Cutthroat Trout Recovery CDOW S-FC-CU-DW010 $95,450 Three separate tasks were accomplished under this agreement to assist with the ~ recovery of native Colorado River Cutthroat Trout (CRCT): ~ 1. A Joint Conservation Strategy among Colorado, Utah, Wyoming and ~ the U.S. Fish and Wildlife Service was completed that assigns recovery ~ responsibilities for each state. These tasks include inventory, non-native fish ~ eradication and hatchery rearing and stocking of pure strain CRCT. This joint ~ agreement implements an MOU signed by Colorado Governor Roemer and Interior Secty. Babbitt pledging to take actions to prevent the need for listing the ~ CRCT under the Endangered Species Act. With CUPCA funding, DOW was ~ able to assign staff to complete this complex interagency and interstate • agreement to assist the restoration of this native trout throughout its range in the • west. ~ 2. Planning, barrier installation, non-native fish eradication and restocking ~ of pure strain CRCT was conducted on Cunningham Creek in Colorado. This was a typical stream restoration project to benefit CRCT. Upper basin reaches of suitable streams are first isolated by means of barriers such as rock/log sills to ~ prevent any upstream fish passage. Next, all fish and invertebrates are ~ destroyed above the barrier by introduction of rotenone, a fish poison • (detoxification at the barrier minimizes downstream impacts). Pure strain CRCT are reintroduced above the barrier and the stream is monitored for several years ~ to confirm success. Special fishing regulations are often established for restored ~ reaches to prevent against over harvest. ~ ~ 3. Because it is impossible to identify pure strain CRCT in hand, DOW contracted with Colorado State University to conduct genetic (DNA) analysis of ~ trout taken from several steams believed to contain pure strain CRCT. It is ~ important to know which streams contain Prue strains so that proper ~ management steps can be taken to protect such streams, and so that these streams can serve as source populations for hatchery production or direct ~ translocation of fish to restored streams.
