The 5th Edition of the definitive reference book on Recirculating Aquaculture Systems
is now available!
Chapter Highlights
Water Quality
Biofiltration & Biofilter Design
Biofiltration & Biofilter Design
Learn how to optimize fish health
and growth rates through the understanding and management of critical water quality parameters.
Chapter includes information on various water quality parameters including:
dissolved oxygen, temperature, nitrogen,
pH, alkalinity, carbon dioxide, and solids.
Biofiltration & Biofilter Design
Biofiltration & Biofilter Design
Biofiltration & Biofilter Design
Learn about the fundamentals of biofiltration and biofilter types for RAS.
Chapters include explanation of the nitrification process, impact of water quality on nitrification, detailed descriptions of biofilter types, pros and cons of biofilter options, biofilter design considerations, and design examples.
Fish Health
Biofiltration & Biofilter Design
Fish Health
An effective fish health management program is a critical part of a successful aquaculture business. Learn about
prevention and control of infectious disease problems in RAS. Chapter covers biosecurity, reducing introduction and spread of pathogens, monitoring and surveillance, diagnosis, and treatment.
Aquaponics
Ozone & UV Irradiation
Fish Health
Interest in aquaponics is growing daily. Learn about the exciting integration of fish and plant culture in RAS!
Chapter includes information on nutrient dynamics, plant growth requirements, hydroponic subsystems, plant selection, approaches to system design, pest and disease control, design examples and economics.
Ozone & UV Irradiation
Ozone & UV Irradiation
Ozone & UV Irradiation
Maintaining good water quality and biosecurity are important for successful RAS. Learn about disinfection of inlet water and disinfection of RAS system water.
Chapter covers factors influencing disinfection efficiency, UV and ozone doses required for inactivation of fish pathogens, methods of ozone generation and transfer, and other methods of disinfection.
Dentrification
Ozone & UV Irradiation
Ozone & UV Irradiation
Managing nitrate level is an important aspect of operating a RAS. Excessive nitrate concentrations adversely impact both fish health and receiving waters.
Chapter covers stoichiometry of denitrification, factors controlling denitrification, effect of denitrification on alkalinity and phosphorus removal, types and design of denitrification reactors.

Cornell University: Designing Recirculating Aquaculture Systems Online Course
This self-paced course explains the basic engineering principles behind a successful recirculating aquaculture system (RAS) design. The objective of this course is to provide sufficient information so that you will be able to design, construct, and manage your own RAS system. Basic principles of business management and securing investment capital for the small family farm will also be reviewed. At the conclusion of the course, you will have received the essential information necessary to design your own system and have a fundamental knowledge of the principles influencing the numerous design options.
