Best Fish Food to Use in Aquaponics

Fish food is the main input in an aquaponics system, therefore it is important to feed your fish the right nutrition not only for the health of your fish but also because fish food becomes fish waste that is the main source of nutrients that feed the plants.

Each fish species has different nutritional requirements that must be met to survive. In their natural environment, fish can seek food that will provide them with their nutritional needs. However, in aquaponics, the fish cannot search for their own food, so they are dependent on the farmers to provide the correct balance of protein, fats, carbohydrates, vitamins, and minerals that they need to grow healthy.

Tips in Feeding Fish in Aquaponics

  • If you have multiple fish varieties in one fish tank, ensure that they all have similar dietary needs, like all fish should be herbivores or omnivores in one tank. 
  • Choose fish food that will provide your fish with all their nutritional needs. Each fish species has certain nutritional requirements that should be met to survive and produce good food for the plants. The fish feed should contain the correct balance of proteins, carbohydrates, fats, vitamins, and minerals. (1)
  • In determining how to feed your fish, decide how much and how often you will feed them. Your fish should be able to eat all the food in around five minutes. (2)
  • Remove leftover food from the tank. 
  • You may need to feed you fish more frequently if you have a small amount of fish in your tank so they will produce the amount of waste that your plants need. If you have many fish for your plants can reduce the number of times you feed them. (2)

To get the most of your aquaponics fish, it is important to have routine over-all maintenance on your system  to ensure that the three main components are working well.  On fish maintenance, give your fish quality and well balanced food. You have the option to give them commercial fish food or homemade fish food. The fish you have in your fish tank will determine which type is better for your feed. Commercial fish can be carnivorous or omnivorous. Commercial fish food is packed with nutrients that will help your fish stay healthy.

Advantage of Commercial Fish Food.

  • Most of the commercial fish food supply all the necessary nutrients (carbohydrates, protein, fats, vitamins and minerals) needed for optimum fish growth and health. 
  • The nutritional content of the fish food depends on each fish species. 

Dis-advantage of Commercial Fish Food

  • The vitamins and minerals in the fish food are heat sensitive, so they need to be stored properly. 
  • Commercial fish food have limited shelf life. 
  • Preservatives such as antimicrobials and antioxidants are often added to extend the shelf life of commercial fish food.
