Completion Report for Minnesota Technology, Inc. (June 30, 1999): Development of Salmon and Trout Aquaculture in Mine Pit Lakes (1989-1991); Commercial Aquaculture Implications for Water Quality (1991-1993); Constructed Wetlands for Treating Aquaculture Wastes (1993-1996)

Abstract

The assessment of environmental impacts associated with intensive salmonid aquaculture, development of tools for predicting impacts, and the development of techniques for mitigating the effects of these potential negative impacts on water resources were the focus of three MTI grants in the period 1989-1996. They are: (1) Development of Salmon & Trout Aquaculture in Mine Pit Lakes, (1989-1991); (2) Commercial Aquaculture Implications for Water Quality, (1991-1993); and (3) Constructed Wetlands for Treating Aquaculture Wastes, (1993-1996) All of these grants were "matched" with grant funds obtained from the Iron Range Resources & Rehabilitation Board, the Minnesota Sea Grant Program (National Oceanic and Atmospheric Administration) and the Minnesota Department of Agriculture. The development of constructed wetlands(#3) subsequently led to the development of an ongoing research, development and demonstration program focused on broader on-site wastewater disposal systems for rural, residential and business needs.
