Hydroculture/Physiology/Aquatic

This is about aquaculture plant and symbiotic organisms in hydroculture systems: the focus is horticultural. Aquaponic and aquascaping organisms are covered in this section.

Hydrophytes
Hydrophytes are aquatic plants. Aquatic plants can transport oxygen throughout its stem, unlike land plants. Hydrophytes need plenty of light, as in their natural environments.

Semi-aquatic plants
Semi-aquatic plants are adapted to live with its root system in both submerged and land based environments. Only during this time, when a plant's root system is submerged it is involved in hydroculture. (cranberry and watercress)

Symbiotic animals
Animals in aquaponics or aquaculture form a symbiotic relationship with plant-life. Aquatic animals need some light like in their natural environments.

Freshwater
Goldfish, Loricariidae catfish, snails and shrimp eat algae.

Plant-like animals
Coral are a saltwater animal that require high maintenance. There are freshwater and saltwater sponge.

Aquascaping
Saltwater aquascaping is for aesthetic reasons. Coral, sponges and saltwater plants may (possibly) form a symbiotic relationship.
