Aquaponics involves the growing of fish and plants together in an integrated system. Catfish aquaponics can be used with catfish since they adapt well to an aquaponic tank. In an aquaponic system, the fish waste acts as a source of food for the plants and the plants provide natural organics for the water the fish live in. The other organics include bacteria like microbes that thrive in the surrounding. They help in converting ammonia, the fish waste into nitrites, then nitrates. The solid waste is then converted to vermicompost that becomes the plant food.
In aquaponics, catfish are among one of the many types of fish one can grow. Since some fish are more durable than others, it is important to choose the type of fish that will adapt to your aquaponic system. There are several advantages to using catfish in aquaponics. The ideal temperature for catfish aquaponics is about 65F to 90F. Colder temperatures can slow down metabolism and food consumption. A warm surrounding improves the fish and plant growth. However, catfish can survive in most climates.
The recommended stocking density would be one fish per three to five gallons of water. This is to reduce stress and give them more oxygen. As the system ages and the water bacteria become stronger, the amount of water can be exceeded. Catfish grow faster in the first breeding years than as they mature. Most fish will take about two years to fully mature. The ideal oxygen levels for the catfish would be four to five ppm(parts per million). Dense tanks may need aeration at night since plants absorb oxygen at this time and may choke the fish. Extra aeration may also be required when temperatures go above 85F.
Catfish aquaponics is a great way to breed the catfish. This is because in the natural surroundings, they have to make their living under diverse environmental conditions.
