Conduct a sensitivity analysis of the IBM so that the model components can be ranked <br />with regard to their influence on the outcome of a simulation. This analysis will identify <br />which components are most important so that an evaluation can be conducted to <br />determine if additional information may improve the predictive capability of the IBM. <br />2. Validate IBM model predictions with data collected in the field. For example, predator <br />removal experiments could be used to evaluate if reductions in predator density enhance <br />recruitment of age-0 Colorado squawfish as predicted by the IBM. <br />3. Experimentally determine probability of capture and attack rates by other potentially <br />important non-native predator fishes on Colorado squawfish. These species might <br />include channel catfish and a representative centrarchid species. <br />4. Conduct laboratory and field studies to describe relationships of discharge, water <br />temperature, habitat availability, and abundance of alternate prey with survival, growth, <br />reproduction, and size-structure of native and non-native fishes in the Colorado River <br />Basin. <br />24 <br />
