Guide To Guide Aquaponics Systems Fish

By Brandon Sharp


Doesn't everyone love fish? You are most likely a full-blown consumer of fish if you are in search of data on the incorporation of new fish into your newly established aquaponics system.

Chances are one of your reasons for wanting an aquaponics system is a good appetite for healthy fish or a passion for healthy decorative fish.

Maybe you already know that a flourishing aquaponics system is dependent upon three key components. Fish, bacteria and plants encompass this trio. Your organic vegetables will not survive without the fish. The fish will perish rapidly with no plants to cleanse the water of toxic nitrates, ammonia and additional waste products, i.e., bacteria.

The plants would not be able to absorb vital nitrates from the water were it not for the bacteria. The removal of any one component would cause the system to fail as each component is important to the system.

Regardless of the size of the setup Tilapia is without a doubt the best preference for aquaponics systems. If you reside in a comparatively warm place in the United States, you can confer with your local agriculture bureau to learn if you can raise tilapia in your backyard aquaponics system.

If tilapia is not a good choice, you have can also raise a variety of other freshwater fish such as koi fish and crappie fish. Most common edible freshwater fish can be used in aquaponics systems.

Some people even breed bass in their backyards. We recommend tilapia because these fish grow very rapidly and are one of the most enduring groups of edible fish around. Tilapias are cichlids and are usually found in the tropics.

As for how many fish to raise in your holding tank, it really depends on how much room you have and the kind of filtration system you've installed in your tank. Small-scale commercial producers habitually add half a pound of fish for every one gallon of water in their tank.

The quantity of fish in the tank has an impression on how much vegetation your aquaponics system can hold. The three factors that come into play when it comes to determining how much vegetation your fish can sustain (indirectly) are; the amount of fish you have in the tank; the age, weight, and size of the fish; and, how much food that is being added to the holding tank daily.

When using elevated growing beds, one square meter (approximately 10.7 sq. ft.) of growing vegetation will require at least sixty grams (approximately 2.1 ounces) of fish food on a daily basis. This is a simple raft setup.

If you are caring for more challenging vegetables such as squash, you need at least one hundred grams of fish food every day. Bear in mind, your plants will be completely reliant on the waste products of the fish and the excess fish feed in the water.

With insufficient fish waste the water will have very minimal levels of organic matter and usable nitrates thereby hampering the ability of the vegetables to grow.

Inversely, too much food in the tanks will result in excess waste in the water and you will be running the risk of poisoning the fish. Finding the balance to sustain both, the fish and the fruits and/or vegetables in your aquaponic garden is greatly advised.
