An Overview of Aquaponic Systems: Aquaculture Components

Aquaponics is an integrated production operation that encompasses recirculating aquaculture systems and hydroponics to produce fish and plants in a closed-loop system that mimics the ecology of nature. Simply said, the fish produce nutrient-rich effluent that fertilizes the plants, and the plants filter the water for the fish. Fish waste from the aquaculture portion of the system is broken down by bacteria into dissolved nutrients that plants then utilize to grow in the hydroponic component. This nutrient removal not only improves water quality for the fish but also decreases overall water consumption by limiting the amount released as effluent. The synergistic relationship of the fish and plants has created a popular perception of sustainability around aquaponics by the general public. Additionally, aquaponics can be scaled from a bench-top hobby unit to multi-acre commercial production facilities

Lake Restoration 2007 Report and 2008 Plan, December 28, 2007

The Department of Natural Resources (IDNR) Lake Restoration Program focuses on restoring impaired lakes to improve the quality of life for Iowans. Communities are rallying around their water resources as they seek population growth and economic success. Communities of the Iowa Great Lakes Region, Storm Lake, Crystal Lake, Creston and Clear Lake are obvious examples, but other communities including Lake View and Brighton are identifying the importance of lakes for their futures as well. The distribution and nature of Vision Iowa grants, Community Attraction and Tourism grants, and now, Great Places, all further emphasize the importance of water to community, quality of life and economic growth
