The Integrated Floating Cage Aquageoponics System (IFCAS) was developed as an aquaculture-horticulture based on the concept of integrated farming system approach firstly in Bangladesh in 2013 to produce fish and vegetables in floating condition where waste materials (fish feces and unused feed) from fish culture dissolved in the pond water and settled on the bottom mud are used for vegetables ...

The objects appear to provide a "visual stimulus in an optical void", [ 2 ] and offer refuge for juvenile fish from predators. [ 3 ]
In the current technology, fish feed extruders play a key role in production lines. Although the majority of the process of the fish feed production occurs in the extruder, grinding and mixing can highly affect the quality of the final product.

[3] [4] The average depth of a raceway for fin fish, such as rainbow trout, is about one metre. [17] This means each section in a raceway should be about 30 m long and 2.5–3 m wide. The landscape should sloped to one or two percent, so the flow through the system can be maintained by gravity.
