There are a number of factors that help determine the types of fish used in aquaponics gardening. These include cost, how much maintenance you are willing to do and the climate you live in. The cost of the fish you choose will depend on where you live and availability of the fish you wish stock your fish rearing tanks with. Maintenance depends on the level of cleanliness the fish needs in the water for them to thrive. These factors you can control. However the climate you live in cannot. If you choose to stock your fish rearing tanks with fish that need warm water, you will have to heat the water if you want them to grow or even survive. You cannot control the climate, but you can heat the water. This however will come at a cost.
The choice of fish for your Aquaponic system is very important. If you plan to only feed your family, then the type of fish they like most would be preferable. The only factor you need to adjust is the fish to plant ratio so the correct amount of nutrients will be provided the plants. The plants will also have to be able to clean the water so the fish will have a suitable environment to live.
Your produce tastes FANTASTIC! Now I’ve grown all sorts of vegetables aquaponic gardening plants in soil, but was astounded at the fresh full flavoured vegetables I could grow with this system.
This revolutionary food production system was devised by Dr. James Rakocy. Dr. Rakocy also known as the «Father of Aquaponics» he is a pioneer and actually the leader of the research teams that coined the phrase «Aquaponics» at the University of the Virgin Islands (UVI) some 30 odd years ago.
Unlike normal gardens you will need any fertilizers or plant foods fish aquaponics aid the growth of your crop. Plus there is no need for slug pellets and other repelants because your plants are not at ground level.
You can use the water for your garden to minimize the waste, but 360 liters is too much for a normal sized garden. Over watering plants causes more harm than benefit. It can introduce waterborne disease such as root rots or mold on leaves.
To help keep the fish in the build aquaponics system system healthy, their environment must be kept constant. For the best results the temperature of the water must be maintained between 70F and 86F. This is a 16 degree cushion, but that does not mean it can fluctuate between these extremes on a daily basis. For the fish not to go into shock, the daily average of fluctuation should not be more than 2F. This will give them a stable environment to live.
Leaves are wilting and dying — when your crops are dying, it is time to consider the type of water flow you are using on your system. Especially if it is now a continuous water flow, chances are your plants aren’t getting enough oxygen so try switching to once hourly or the ebb-and-flood method.
This is a type of system were you can start small and expand as you go. You can try it out with a low cost system and grow food for yourself. Fine tune it and learn how to get the most production. And if you want, expand from there and start selling what you produce. I can’t promise you are going to quickly make a fortune with aquaponics, but there is a lot of business potential. And at the least, growing plants and fish this way is a whole lot of fun, and will be worth the fresh fish and vegetables that it will produce for you.
