This literature review has been written to examine different tilapia farming practises both in semi-intensive and extensive systems. Extensive culture is not mentioned sine it is not considered to be a real commercial production as the control over the system is quite limited and even semi-intensive system is being replaced by intensive system due to technological developments, high demand and increasing market prices of tilapa. In first chapter, environmental and nutritional requirements are also mentioned as they are closely correlated play a key role in a succesful production. The results of some recent studies and experiments suggest that tilapia has some superiority over other culture fish like faster growth, ability to utilize different feeds, wide tolerance for high stocking densities and environmental conditions. In addition to these advantages, tilapia do very well in integrated culture systemsboth with aquatic species; carp and shrimps, also crops like tomato and lettuce as well. As a result this study is conducted to prove the advantages of commercialtilapia production covering economic values.

Excerpt from the Book
3.1 AQUAPONIC SYSTEM
Formerly, semi-intensive pond production was the main method for tilapia farming particularly in developing countries. Today, with the increased demand for tilapia in the market, climatic changes and year round production chance, shortage of fresh water supply and the increasing land costs have been the driving factors for the use of intensive indoor re-circulating systems
In aquaculture facilities, regardless of fish species being farmed, wastes that disposed to water basically can be divided into three groups; 1) uneaten feeds, 2) indigestible feed substances and 3) feaces. In addition, metabolic products such CO2 and total ammonia nitrogen (TAN) might be considered as the fourth group. In aquaculture, with presence of those three factors; phosphor, ammonia, suspended solid particles amount increase and dissolved oxygen level in culture water dramatically drops. As well, increasingly stringent environmental regulations make aquaponics a major solution to overcome these critical problems (Lennard, 2004).
Aquaponics is the integrated production of plants (hydroponic) and fish in a water re-circulating system with the biofiltration process by nitrifying bacteria (Tyson et al., 2007) , while hydroponic is referred to plant production without soil and in a limited area in compare to land based plant production. Bacteria in the gravel and associated with the roots of the plants play a critical role in the nutrient cycle; absence of these organisms would stop the functioning system (Rakocy, 1999a ; Diver, 2000). Hydroponic system has several advantages alone. A well known superiority of hydroponics over conventional agriculture is, the year-round production of crops when the supply is decreased due to seasonal changes. The second one is considered to be the elimination of soil-borne diseases, as the crops are grown in an aquatic medium.
Summary of Chapters
CHAPTER ONE: This chapter details the critical environmental parameters (temperature, pH, oxygen) and nutritional requirements (protein, lipids, vitamins) essential for successful commercial tilapia production.
CHAPTER TWO: This section compares semi-intensive and intensive culture systems, providing a technical analysis of pond fertilization, tank culture, cage culture, and the implementation of bio-floc and recirculating systems.
CHAPTER THREE: The final chapter explores integrated culture approaches, specifically focusing on the sustainability and economic benefits of aquaponics and the synergies achieved in tilapia-shrimp and tilapia-carp polyculture systems.

Which keywords characterize this work?
Key terms include tilapia, intensive culture, aquaponics, polyculture, nutrient requirements, bio-floc, and sustainable production.
How does the aquaponic system improve water quality?
The aquaponic system uses the hydroponic subsystem as a biofilter where nitrifying bacteria convert toxic ammonia and nitrite into harmless substances, which are then absorbed by plants as fertilizer.
Why is polyculture beneficial for tilapia farming?
Polyculture maximizes resources by utilizing different feeding habits of species in the same area, often improving overall water quality and producing higher yields compared to monoculture systems.
