| The objectives of this study were to compare the performance of two feed treatments on a population of rainbow trout, Oncorhynchus mykiss, reared in a linear raceway system, which utilized mine water from a mine water treatment facility (MWTF); to measure and compare waste outputs; to monitor the water quality of the system; and to identify the impacts, if any, of the water quality on the fish population. Toward the end of the study, a spike in the turbidity of the water source led to additional objectives. First, the water quality was characterized during the events to determine the extent of the disturbance. Second, the impact of the events on the health and growth of the fish was evaluated. Next, the vulnerability of aquaculture systems that utilize mine waters to such events was addressed. Finally, additional water quality treatment options were identified and preliminary designs were completed. (Abstract shortened by UMI.)... |
