The easiest fish to farm in an extensive fish farming system are Catfish, Carp, and Tilapia. This is a dummy description. Aquaponics is well known for its efficiency and typically generates at least 80 percent of revenue from plant harvests produced from fish waste – as confirmed by chief operations officer Brandon Gottsacker who says (in regard to growing lettuce from the waste produced by salmon which has an FCR of 1:1): “That’s 1lb of input into the system and 10lb of healthy organic food out of the system.” Most importantly, such systems rely on adequate solids removal and perfect control of ion concentrations imperative to growth of vegetation in water. One of the big advantages of fish farming is that it's a fine entrepreneurial opportunity.

Using the actual research data, an internal rate of return (IRR) of 13 percent was calculated using the poor production performance of shrimp growing at a low 60 percent survival, 0.7g per week and a harvest biomass of 2.5kg/m3. trout farming) or flow-through raceways.
