"The fish to plant ratio in aquaponics is roughly 1:2 (one fish:two plants). By having one fish per two plants this should provide for optimum fish production, as well as good plant growth. An optimum aquaponics system will mean the plants will work well at the nutrient removal, but also that the plants will receive enough nutrients to grow."

"There is no such thing as the perfect aquaponics fish to plant ratio. It is different for each growing technique and kind of crop you are going to use."

"There are several important factors to consider in figuring out what the right fish to plant ratio is in aquaponics. There is no exact fish to plant ratio, and every aquaponics system is different, but this ratio will guide and help you find the best balance for your aquaponics system.
- Feeding Rate
The fish to plant ratio depends on the feeding rate in an adequately maintained aquaponics system. Fish use about 80% of the food they consume and excrete 20% as waste.
The amount of feed added to your aquaponics system daily is considered per square meter of plants growing area. This ratio also depends on the feed used and the plants grown in the system; fruiting vegetables requires about one-third more nutrients that leafy greens to thrive."

"In aquaponics, the number of plants to be grown is directly proportional to the amount of fish feed you put in the system. Thus, sufficient fish should be present in the system, and you need to feed them well. A high plant density means a good number of fish and favorable water quality without exchanging large quantities of water or using any complex filter gadgets.
Similarly, the removal of ammonia and nitrites from the fish waste is essential, as it is toxic. A high nitrate level can result in tank water poisoning, which can kill the surviving fish species. To avoid this, more plants are required, as they act as biofilters to clean the water as well as process the wastes."

"One of the most important factors of a healthy and productive aquaponics system is ensuring that the ecosystem of the plants, fish, and bacteria is balanced at all times. This means that an aquaponics system is sized correctly to balance the plants' nutrient production from fish waste and nutrient uptake.
Having the right fish to plants ratio is essential in maintaining balance in an aquaponics system."

"Harnessing the power of aquaponics is both an art and a science, allowing for sustainable and efficient food production. The heart of this unique ecosystem lies in achieving the ideal fish to plant ratio—a crucial balance that ensures healthy growth for all budding aquaponic enthusiasts."
