The bull shark is a euryhaline species that moves at will from fresh to salt water, and many marine fish make a diel vertical migration , rising to the surface to feed at night and sinking to lower layers of the ocean by day.
Saltwater aquaponics (also known as marine aquaponics) is a combination of plant cultivation and fish rearing (also called aquaculture), systems with similarities to standard aquaponics, except that it uses saltwater instead of the more commonly used freshwater. In some instances, this may be diluted saltwater.

Striped bass spawn in fresh water, and although they have been successfully adapted to freshwater habitat, they naturally spend their adult lives in saltwater (i.e., they are anadromous). Five important bodies of water with breeding stocks of striped bass are: Miramichi River , Chesapeake Bay , Massachusetts Bay / Cape Cod , Hudson River , and ...
