21st Annual Recirculating Aquaculture Systems Short Course

Engineering Design for Recirculating Aquaculture (RAS), Hydroponic, and Aquaponic Systems

This three day course  (Tuesday – Thursday) reviews the basic engineering principles behind a successful recirculating system (RAS) design. The objective of this course is to provide sufficient information so that the participant will be able to design, construct, and manage their own RAS system. We also cover the basic principles of state-of-the-art hydroponic (plant) and aquaponic (fish and plants) techniques and cover the management of these systems. Several design options will be explored. Basic principles of business management for the small family farm will also be reviewed by guest speaker Michael Finnegan, CEO Continental Organics L.L.C.

The following topics will be addressed:

  • Water quality monitoring and measurement
  • Engineering design of individual unit processes
  • System management
  • Fish health management
  • Economic and risk evaluation
  • Indoor Shrimp
  • Tours of local aquaculture/hydroponics facilities

A “distance” learning opportunity for aquaculture only is also offered.

At the conclusion of the workshop, participants will have the essential information necessary to design their own systems and have a fundamental knowledge of the principles influencing the numerous design options.

In addition, a Farm Tour will be made to Continental Organics Inc. (2 acres of hydroponics and a 100,000 lb/year tilapia system); see www.conorgnx.com for farm details (within 10 minutes of educational venue).

Tilapia – A Companion Crop for the Home Gardener

Tilapia are known as “aquatic chicken” because they are easily grown and produce mild, white filets. Increasingly, as wild capture fisheries become depleted, there is a need to look for other protein sources. Aquaculture can help meet some of this demand. In the last ten years, tilapia have made their appearance in local supermarkets. Today, tilapia rank are the fourth most highly consumed seafood in the United States.

Tilapia can be farmed in sustainable fashion in small farm ponds. The fish are grown as a companion crop to common vegetables, such as lettuce and herbs. Waste from the fish are used to fertilize the vegetables. The organic material in the fish pond supports algae which help to filter and maintain water quality. The fish ponds can also fertilized with agricultural wastes which helps to reduce production costs.

Raising fish and vegetable crops in an integrated system is known as aquaponics and helps provide food in a sustainable manner. For the home gardener, this type of sustainable food production can be accomplished using fish tanks in outdoor sheds or small greenhouses that integrate hydroponic vegetable production or that are in proximity to traditional family gardens.
