NNNOI04: Removal of Channel Catfish from the Lower Yampa River (FWS, $112,000) <br /> <br />This study builds on results of a previous project to develop an effective control program <br />for adult channel catfish in Yampa Canyon. The goal of channel catfish removal in <br />Yampa Canyon is to sufficiently reduce the abundance of adult channel catfish such that <br />predatory and competitive impacts on growth, recruitment, and survival of resident <br />humpback chub are minimized, Study objectives are to: I) reduce the abundance of adult <br />channel catfish in Yampa Canyon by capture and removal (lethal); and 2) determine fish <br />community responses to reductions in channel catfish population size, including channel <br />catfish reproduction and recruitment. Total out year cost: $121,800. <br /> <br />C-31 NNNOI02: Yampa Northern Pike Spawning Habitat Exclusion (CDOW, $50,000) <br /> <br />The goal of this project is to reduce spawning and reproduction by northern pike in <br />Yampa River habitats in order to reduce the abundance of pike in endangered fish critical <br />habitat downstream. The study will: I) determine feasibility and logistic requiremenls of <br />using temporary low-cost screening to prevent access to these habitats by spring <br />spawning, adult northern pike on a reach-wide scale from Craig to Steamboat Springs; <br />2) implement exclusionary screening of potential pike spawning habitats on a reach-wide <br />scale and mechanically remove pike from any habitats where access by pike to screened <br />spawning habitats has been gained due to temporary screen failure; 3) monitor <br />effectiveness of exclusionary screening using trend analysis of northern pike capture <br />rates; and 4) evaluate and recommend design improvements in existing irrigation <br />diversion and return systems to reduce pOlential northern pike spawning habitat or <br />facilitate screening control. Total out year cost: to be determined. <br /> <br />" <br /> <br />I: <br />\: <br /> <br />98a. NNA/9802: Translocation of Northern Pike from the Yampa River (LFL, $95,700) <br /> <br />The goal of this project is to improve survival of endangered fishes in the Yampa and <br />Green rivers by reducing the number of adult northern pike in critical habitat. Pike are <br />collected between Milk Creek (RM 120) and the entrance ofYampa Canyon (RM 46) in <br />the early spring as backwaters and tributaries fill during lhe ascending limb of the <br />hydro graph when the pike typically congregate in off-channel habilats for spawning, <br />feeding, or resling. The pike are then translocated to isolated ponds or reservoirs in or <br />near to the Yampa Valley that conform to Nonnative Fish Stocking Procedures and are <br />accessible to anglers. This project also will determine effectiveness ofremoval in terms <br />of number and size of northern pike removed over time. Total out year cost: $73,000. <br /> <br />98b. NNNO I 03: Translocation of Northern Pike from the Upper Yampa River (FWS, <br />$62,000) PLACEHOLDER <br /> <br />This project also is intended to improve survival of endangered fish in the Yampa and <br />Green rivers by removing pike from the upper Yampa River above Craig, Colorado <br />(-RM 135). This project is a "placeholder" as the Program's Management CommiUee <br />deferred a decision on whether to implement this project until after preliminary results of <br /> <br />C-IO <br />
