Evaluation of a Hidrostal Pump Fish Return System

摘要: Abstract We tested the effectiveness of a Hidrostal pump and filtered mercury vapor light system for attracting, concentrating, transporting fish commonly impinged on water intake structures thermal electric generating stations Great Lakes. In general, effectively transported test with relatively low mortality rates. Mortality varied among species, rainbow trout (Salmo gairdneri) significantly hardier than yellow perch (Perca fiavescens) alewife (Alosa pseudoharengus). also generally increased at higher pumping speeds, while was greater in long transport loop short loop. tests attraction capture, addition efficiency capture system. Other directive cues (bubble curtains, strobe lights, fields) did not improve pump-mercury...
