Human nature is the one factor the farm or RAS designer cannot control; humans are by nature lazy and we take the shortest route every time.
Heating a commercial farm is still the biggest fundamental left unattended in the Highveld of RSA.
It is commonly advertised by system designers to prospective farmers that 20kg/kl is the norm.
There are two main forms of bio filters, aerobic and anaerobic
Solids represent a huge amount of waste that needs to be removed from the system as soon as possible.
There are several fundamentals that need to be followed in every aspect of life, aquaculture is no exception. The insights gained and shared in this series of articles are not from a PhD or training courses. Instead it comes from trial and error by buildi
Courtesy of James Ebeling an introduction to some of the basics you should keep in mind RAS
Effective biosecurity systems in tilapia farming will help ensure farmer success.
System management is an ongoing balancing act.
Anytime fish are cultured, they are crowded and they are stressed.
Pure oxygen can simply be injected into pipes leading to the tank.
Oxygenation adds cost to recirculation production, but the benefit is that system production can be increased 50% or more.
There are a variety of ways to get air into water.
Submerged biofilter options are important in RAS.
Wet biofilters have an important role to play.
The oxidation of reduced nitrogen (NH3) by bacteria is a natural process known as nitrification.
Alternatives to granular media filters.
Removing solids is an important part of keeping your RAS in good shape for your fish.
Removal of solid waste in recirculation aquaculture is complicated by the fact that the loosely aggregated fecal material and uneaten food tend to break into small pieces in the water.
Tanks for recirculation aquaculture have been made from a variety of materials.
