My start up consisted of a portable 10ft x 20ft car port, with 4 - 4 x 8 grow troths, a self constructed 4ft x 4 ft x 3ft high self constructed 330 gallon tank and a 100 gallon stock watering tank and 220 fingerling tilapia. That was in July 2011. A major learning experience!
In 2013 I expanded to 4 additional 275 gallon polly fish tanks and 12 additional 4 x 8 grow troths. and I am about to add 4 more grow troths. The new growing area is housed in a 42ft x 26ft "hoop house".
My gross sales for 2013 was just over $200.00, from the original 4 grow troths.
