<br />chemical, and biological characteristics of the diverse array of bacKwater <br />habitats in the Green River between the confluence with the Yampa River and <br />the White River where larval, YOY, and 1+ Colorado squawfish have been found. <br /> <br />The objectives of this study were: <br /> <br />1. To identify energy sources which fuel secondary productivity in <br />nursery habitat. <br />2. To identify important trophic interactions leading to production of <br />food organisms available to young Colorado squawfish. <br />3. To identity food organisms utilized by young Colorado squawfish. <br />4. To quantify competition between fish species, with emphasis upon <br />interactions between young Colorado squawfish and other species for specific <br />size food items. <br />5. To estimate predator-to-available-prey ratios for nursery habitats. <br />6. To quantify the potential for predation on various sizes for young <br />Colorado squawfish. <br />7. To limnologically and physically characterize nursery areas utilized <br />by larval Colorado squawfish. <br /> <br />Characterization of physical, chemical, and biological attributes of these <br />backwaters, such as morphometry, structure availability, densities of phyto- <br />and zooplankton and benthic macroinvertebrates, and predator-prey <br />relationships are necessary to identify possible limiting factors that may <br />control or affect the survival of Colorado squawfish populations. <br /> <br />10 <br />
