Marine cage aquaculture is widely used in lakes and at sea. Fish are confined in cages constructed of fiber net or wire suspended from a floating frame. Traditional marine cages are often placed near the coast for operating convenience and the fish waste is polluting the seabed and the coastal area, destroying marine life.

Based on this observation, NOVATON developed the NOVATON EEVO (Environment Evolution) marine cages. The NOVATON EEVO cages are sustainable by extracting waste, minimizing the quantity that disperses into the environment. 

The bottom of the NOVATON EEVO marine cages is covered with a membrane and a basket that collects the fish waste and the remaining feed, until it is extracted on a daily basis.
