After all, that is the only thing that you add to the system – and what you add directly affects how much your fish and plants thrive!

  • What food is good for your fish
  • How much to feed them
  • When to feed them
  • How to save money on fish food

#1: Why is the fish food important?

The food you give to your fish contributes much to the waste that the fish produces. Therefore, the health of your plants also indirectly depends on the fish feed. Also, if you are using the Aquaponics system to harvest the fish as well, then food automatically becomes important for their health and development as well.

The natural next concern is…

#2: What should good fish food contain?

Any good fish food should actually be a mix of proteins, fats, carbohydrates and minerals – even your fish need a balanced diet! But here there are a number of things to consider. Firstly, the kind of feed and exact compositions tend to differ from fish to fish as different fish need different feed. Also, fish feed is available in two forms commercially – omnivorous and carnivorous. Again, which you choose depends on the fish you keep.

Let’s now take a look at…

#3: Which is the best fish food?

While there are many different fish feed options available in the market, and they all come packed with all the right nutrients. In fact, when you go to buy any fish food from the market, the seller or the packet will display what fish breeds it is good for. Unfortunately, however, many fish feeds these days come with GMO ingredients. And you may not want to give these to your fish, if you are conscious about the harms and avoid it on a whole. In that case, you can always check out the array of organic fish feed options available in the market. You can also check out our section of cheaper fish feed below – where we’ll be talking about organic options!

Next we’d like to talk about…

#4: When and how to feed the fish?

This is a difficult question to answer since there is no one-size-fits-all solution here. It will differ from fish to fish, age to age and system to system. But we’ll look at all the factors here:

  • If your fish aren’t able to eat up all the food you give them in 5 minutes or so, then you’re giving too much food – reduce the amount for successive feeds. Also make sure to remove the excess food that does not get eaten.
  • If you have fewer numbers of fish then you will need to feed more frequently so there is more fish waste produced for your plants. For more fish, feed fewer times.
  • As for fish feed timings, you should decide this for yourself depending on how many feeds you will be giving them in a day. Space the feeds out almost equally.

And finally, let’s check out…

#5: How can I save money on fish food?

There are a number of alternate feed options that are all organic, and that you can make at home and save some money on:

  1. You can grow your own duckweed, which is excellent protein rich food for your fish. Also since it is a weed that grows very fast in any Aquaponics system, it takes little hassle!
  2. You can also grow worms, but they are more difficult to grow in large quantities, so this can be used as food occasionally.
  3. There is another option, and that is Black Soldier Fly larvae. This can be bred easily and you can even get a device that harvests the larvae making the job easier for you!

The bottom line is – Aquaponics fish food is one thing that you need to put considerable thought and consideration into. But that doesn’t mean that it is difficult to come by – or very expensive. Keep these pointers in mind, and pretty soon you will have a thriving Aquaponics system!
