In this video, UC Davis Aquaculture explains what is Recirculating Aquaculture System? We also  tour our RAS fish farming system that supports our vertical aquaponic greenhouse. We discuss the 4 components of a recirculating aquaculture system and introduce various common components used in a commercial aquaculture fish farm or on an aquaponic farm. The 4 components of a recirculating aquaculture fish farm include clarification, biofiltration, gas stripping and oxygenation. In this aquaculture video we break each component down and discuss the technology common in RAS. Our RAS is only designed to provide nutrients for our vertical aquaponic greenhouse. The system is a simple system that can easily be copied in backyard aquaponics applications, aquaponics for beginners or for STEM education in school systems. It is effective without all the frills. The goal of our system is to be low maintenance but still have excellent water quality for the care of our hybrid carp. We utilize a submersible pump which is maintained in our sump which is an IBC tote. Water is pumped to each of fish tank. Water gravity flows up and out of the dual standpipe to our first clarification step which is a round tank that we have adopted as a swirl filter. From the swirl filter water will flow into a series of IBC totes. the first IBC tote is a dual purpose are (clarification and biofiltration). We are using matala pads as roughing filters. From the secondary clarifier  water will enter the moving bed bioreactor (MBBR). Here we are using k1 media and mixing the system well using a regenerative blower which is a powerful air pump. After this step, water will flow back into our sump.
