Aquaculture, the farming of fish, is a complex system that requires constant management. It is not to come across dire, but maintaining a fishery demands delicate balance. Once a system is in place, regarding pH balances, oxygen levels, and the scheduled recycling of water through the hydroponics system, it becomes easier.
Conducting continual maintenance ensures that disease is prevented within your aquaponics system. This is incredibly important, not only for the livelihood of your fish, but also the livelihood of your other sea creatures and your plant life.
It can be tricky keeping the pH balance levels right for your sea life because you have to consider your fish, plants and the bacteria. Since plants prefer a pH balance between upper five and low six and your fish and bacteria prefer a range of high seven and low eight, it is a good idea to try to meet somewhere in the middle in the high six and low seven range. One thing your fish cannot handle is a continual sway of pH balances. Going from too acidic to too alkaline and back again can quickly kill your farm. Continue to gauge the balance and adjust accordingly.
Of course everything needs oxygen. That’s why everything is able to breathe on earth and not outside of the atmosphere. Fish should be receiving an ample amount of oxygen from pumps or filters. There needs to be a continual motion of bubbles in your tank. This is easy to keep watch out for. Also, putting air stones and wood at the bottom of your tanks can help provide good oxygen levels.
Excretion and Ammonia Levels
Fish excretion is the reason behind having an aquaponics system. It is the food that feeds the plant life. This excretion is broken down by a bacterium that turns it into nutrients. Without recycling the water, however, the excretion can become deadly for the fish due to an increase in ammonia levels. Keeping the water fresh and clean is utterly important.
This part of raising fish is the most obvious and should be the easiest, but even it requires dedication. Overfeeding fish isn’t too much of a concern. Fish will eat what they want, but what remains could be hazardous if not cleaned up. When uneaten food sinks to the bottom, it can cause contaminants to seep through the tank. Make sure your fish are consistently fed and that you clean up what they don’t eat.
Before setting up your aquaponics kit, be certain to have all the necessary equipment to keep your fish and sea life alive and well. Remember that without healthy sea life, your plant life will suffer as well. Aquaponics allows for nature to thrive off of nature, just as nature intended. So protect your fishery and it will provide the food production you anticipated.
