After the model was adjusted to reflect input from our first workshop and data sources <br />for parameter estimation were identified, we began to accumulate data pertaining to all <br />population parameters for the Colorado squawfish populations. Three subpopulations <br />were identified and all available data were tabulated and analyzed to provide the best <br />estimates for parameter values possible (see model section below). To determine our <br />effectiveness at finding data (and understanding them) we met with T. Czapla, C. <br />McCada and D. Osmundson to discuss the data we tabulated and the analyses we <br />pertormed. We also discussed the areas where data were sparse or nonexistent. <br />Finally, we held a workshop, similar to the initial one at Utah State University, in <br />conjunction with the All-Scientist meeting for the Upper Basin at Lake Powell to discuss <br />model structure and data sources for Razorback sucker and Humpback chub. <br />Approximately 20 scientists attended that workshop. <br />In this report, we provide specitac models for three of the above fish species (data are <br />virtually nonexistent for bonytail chub), data synthesis required to estimate relevant <br />population parameters where possible, and some examples of how the models can be <br />used to determine target values or management targets for population stabilization or <br />enhancement. <br />3 <br />
