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

摘要

A fish test circuit (1)for the evaluation of waterway barrier bypass systems is shown and described, the circuit including a conduit (10) having at least one bypass system test station (20), and preferably a plurality of separate bypass system test stations. Further, the circuit includes water flow (200) within the conduit(10) , fish introduced into the conduit, and systems for monitoring and measuring the effectiveness of the bypass system under test. In the preferred embodiment of this invention, the measurement of the effectiveness of the bypass system under test includes determining the survival or mortality rate of the fish as they pass through each bypass system undergoing test, and/or physical examination of the fish. The test circuit may be a closed loop or a side channel of another waterway. An important benefit and feature of the test circuit is the capability to evaluate multiple and differing bypass systems under similar water flow, water condition, and water quality conditions.
