Growth Rate

Exponential, linear, and plateau growth rates are the normal course of life of a tilapia. Depending on the genetics, the growth rate is linear up to from 1-3 lbs of weight.

Stocking Rate

1/4 lb per gallon without supplemental pure oxygen. With oxygen, stocking up to 1 lb per gallon is possible. -[1]
5-9 lbs per cubic foot with oxygen - [2]. Same? 1 cubic foot = 7.5 gallons. Thi
Bright Agrotech - correct stocking rate of 1 lb for 8-10 gallons of water - [3]. This rate allows for flow aearation, as opposed to air pump aeration - allowing the splash of flowing water to provide adequate oxygen. Summary: this figure is 1/2 or less the MSU publication above - so consistently conservative.
3 gallons to one pound of fish - [4]

Southeast Asia stocking of fry - not adult carrying capacity of the water - .7 kg/m2 - [5] - if 1 meter deep, that is 264 gallons

In tilapia monoculture systems, animal manures stimulate phytoplankton which the tilapia feed on - [6]
Tilapia can feed on duckweed alone. Feed Conversion Ratio is best on duckweed alone, though the growth of the fish was half of that on a mixed diet. - Trials
