FISH TEST CIRCUIT AND METHOD FOR EVALUATION OF WATERWAY BARRIER FISH BYPASS SYSTEMS

摘要

This invention of a fish test circuit for the evaluation of waterway barrier bypass systems is a conduit having at least one bypass system test station, a means for providing water flow within the conduit, a means for introducing fish into the conduit, and a means for measuring the effectiveness of the bypass system(s) under test. In the preferred embodiment of this invention, the means for measuring the effectiveness of the bypass system(s) under test includes a means for determining the survival or mortality rate of the fish as they pass through each bypass system undergoing test. The test circuit may be a closed loop or a side channel of another waterway. An important feature and benefit of this invention is the capability to evaluate multiple and differing bypass systems under similar water flow, water condition and water quality conditions.
