Fish biology is influencing yield of aquaponically cultured basil (Ocimum basilicum), parsley (Petroselinum crispum) and marjoram (Origanum majorana) with better harvest in combination with Nile tilapia (Oreochromis niloticus).

Weight gain of African catfish (Clarias gariepinus) was better in comparison with Nile tilapia (Oreochromis niloticus).

Steadily increasing feed input per day resulted in a three phase water oxygen distribution (run in phase, exponential phase, and accumulation phase) in a coupled aquaponic system with a steady state at 150 g feed input per day.
