Catfish are one of the most popular fish for aquaponics systems. They can tolerate a large variation in water temperatures, are not territorial, and breed quickly. Catfish have a pleasant taste and are also slow-growing, so they will not outgrow your system, making them very suitable for aquaponics. This article discusses the essential factors you need to know about raising catfish in your aquaponics system.
An aquaponics system is considered functional and established once system cycling is done, the nitrifying bacteria is established, and there are no signs of fish stress and plants' nutrient deficiencies. One crucial factor that has a vital role in aquaponics system cycling is nitrate.
Fish food is the main input in an aquaponics system; therefore, it is essential to feed fish the right nutrition not only for the health of the fish but also because fish food becomes fish waste, which is the primary source of nutrients that feed the plants.
