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. 1. 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.. Approach to aquaponic feeding rate ratios. the rakocy/uvi feeding rate ratio is expressed as the grams of fish feed required to be fed to the system per day as related to the plant growing area (expressed as grams of fish feed/square meters of plant growing area per day; or g/m 2/day). the rakocy approach was determined by taking. Fish are most comfortable in large tanks, so estimate at least 1 800-gallon tank for a profitable aquaponics operation. step 2 - add grow beds in a ratio of 1:1 start with a grow bed ratio of 1:1, which is 800 square feet of grow beds for an 800-gallon fish tank..
Hence, the best way to determine the stocking densities more accurately is in terms of pounds. a 6 -10 gallons for every pound of fish is a fairly safe ratio in any type of system. the fish feeds according to their body weight. an adult fish can consume feed equals to the 46–68 percent of their body weight daily.. 1. use a feeding rate ratio for design calculations in a correctly designed and balanced aquaponic system, the ratio between fish and plants is based on the feeding rate ratio. the feeding rate ratio is the amount of feed fed to the fish daily per square meter of plant growing area.. Many in our aquaponic gardening community have pointed out that we need some basic aquaponic gardening rules of thumb. why? from grow bed area, determine the fish weight required (pounds or kg) using the ratio rule 1 lb (.5 kg) of fish for every 1 sq ft (.1 sq m)of grow bed surface area, assuming the beds are at least 12″ (30 cm) deep..
