Aquaponics is a method of growing plants in water with the help of fish. The fish and plants live in a symbiotic relationship. Each one provides the needs of the other. It’s an effective way of growing plants, particularly veggies. If you’re familiar with aquaponics you may be wondering what fish you should use with aquaponics.
You need to take the following factors into consideration when deciding on the type of fish to add to your aquaponics system:
1. WILL THE FISH BE EDIBLE OR ORNAMENTAL?
If you are wanting to raise edible fish (eg: tilapia) you need to consider that they can be tricky to maintain and need specific conditions to thrive. Ornamental fish (eg: goldfish) on the other hand, are less costly and easier to maintain.
2. TEMPERATURE
You need to consider the temperatures of the area you live in. Some fish need cold water temperatures and some need warm water temperatures. So keep this in mind when choosing your fish.
3. AVAILABILITY IN YOUR LOCATION
Always check what fish are available in your location. Additionally, it’s also essential to check which fish are legal to farm in your area. Some fish also require a permit to farm. So be sure to check into this.
4. THE LEVEL OF MAINTENANCE REQUIRED FOR THE FISH
Fish differ in the level of care and maintenance that they need to thrive. Some are very sensitive and need a high level of care while others are more hardy and require less care. If you’re looking for fish that does not need costly maintenance then choose fish like, tilapia, koi or goldfish.
5. HOW THE FISH BREED
This is an important consideration. Some fish, like tilapia, breed very quickly in captivity. On the other hand, you get fish species that won’t breed at all in captivity. As a result, you need to carefully choose your fish so that you have one that will breed well.
6. THE DIET YOU FEED YOUR FISH
The food your fish consume becomes the nutrients that sustain the plants. As a result, it’s essential to make sure that you are feeding them a diet that is well-balanced with proteins, carbohydrates, fats and vitamins and minerals.
This is important to factor into consideration when choosing the fish for your aquaponics system. If you choose fish with high maintenance needs it will ultimately impact how much you will spend financially.
7. THE SIZE OF THE TANK
The size of the tank depends on the type of fish you choose. Some fish grow big and need lots of space. In addition, some fish also don’t thrive in a crowded tank. So keep this in mind when choosing the fish for your aquaponics system.
We’ve looked at some of the factors to keep in mind when deciding what fish to use with aquaponics. Use these guidelines to help you decide which type of fish to go with for your aquaponics system.
In addition, it’s also a good idea to join your local FB aquaponics group. It’s a great place to ask any questions you may have and get feedback from people who have experience with aquaponics.
