Abstract
A new aeration concept developed at the St. Anthony Falls Hydraulic Laboratory
can significantly reduce the operating costs for aeration in aquaculture applications. This
concept has been thoroughly evaluated in laboratory studies over a period of several years.
This research indicated that energy savings of 30 percent or more are possible. This report
describes the application of this technology to the development of an aeration system for
use in deep water fish farming. Performance measurements were made using procedures
established by the American Society of Civil Engineers which is the standard of the
industry.
This project was a joint venture between the Saint Anthony Falls Hydraulic
Laboratory (SAFHL) and Minnesota Aquafarms, Inc. (MAF). SAFHL was the lead
institution in the program. The project was carried out in four phases: 1) Design and
laboratory evaluation of a configuration specifically tailored for use in the fish pens of
Minnesota Aquafarms, 2) Construction .of a prototype system, 3) Operation and evaluation
of the prototype system and comparing its performance and energy efficiency against that
of the existing aeration system, and 4) Data analysis and final report.
The results of the field studies provided valuable data that will be useful for the
design and implementation of improved aeration systems for a broad range of aquaculture
applications. Significant information concerning the differences in the operational
characteristics of aeration devices with circular and rectangular planform has been obtained
This information will be useful in developing improved versions of the system.
