Evaluation of models for developing biological input for the design and location of water-intake structures

An approach for assessing multiple stimulus/response relations between fish and water intake structures is presented in this report. The approach stresses stimulus/response relations influencing fish and shellfish distribution and is made up of two methods. The first places emphasis on spatial and temperal distributions of populations; information is presented in the form of a non-predictive model, which allows for organizing information and documenting review processes. The second approach encompasses functional relationships between environmental and biological stimuli and responses of organisms. By using the two methods together, functional relationships can be evaluated to define the distribution of a fish or shellfish species. This information can then be used to resolve questions relating to impingement and entrainment
