A special fish tank system to commercially raise and to sell salt-water fish which uses tidal changes to replenish the seawater and remove stale water from the fish raising environment. This system also known as fish-farming or mariculture is for the raising of fish as a food product. It includes a water tight tank, a protective berm to keep out unwanted high waters and storms, a cover, a truck approach, an influent pipe that runs from the bottom of the ocean to the tank an elevation drop wherein the high tide permits and replenishes new seawater to the tank through tidal shifts and an effluent pipe with a cage to contain the fish. Optional water filtering devices including a bacteria remover, an electro coagulation machine, and a Seawater Reverse Osmosis Systems (SWRO) are anticipated.
