Some inland aquaculture systems involve using a range of separated species to increase its productivity. An example of this would be where water is used to culture a fish specifies, which is then diverted to tanks of shellfish which feed on the fine particles left by the fish, which then is diverted to algae species which remove the dissolved nutrients, and then last of all the water is sent to a horticultural system.
